VideoView to match parent height and keep aspect ratio

VideoView to match parent height and keep aspect ratio - android

I have a VideoView which is set up like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/player"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<VideoView
android:id="#+id/video"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:layout_centerVertical="true" />
<ProgressBar
android:id="#+id/loader"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" />
</RelativeLayout>
But the VideoView matches the width of the parent container, and then the height is set according to the aspect ratio of the loaded movie.
I would like to do just the opposite, I want the VideoView to match the height of the parent while keeping the aspect ratio intact, the video will be clipped on the sides.
I managed to stretch the VideoView to fill the parent but then the aspect ratio is not kept.
Another thing is, I'm adding MediaController to the VideoView like this:
MediaController controllers = new MediaController(this) {
#Override
public void hide() {
if (state != State.Hidden) {
this.show();
}
else {
super.hide();
}
}
};
controllers.setAnchorView(videoView);
videoView.setMediaController(controllers);
videoView.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mediaPlayer) {
controllers.show();
}
});
This works great, and the controllers always stay on, but the height of the controllers is not being taken into account when calculating where to place the video (since it's vertically centered).
My two questions then are:
How do I make the VideoView match the height of the parent yet keep the aspect ratio?
How do I make the VideoView take into account the height of it's controllers?
Thanks.

You should extends from the built-in video view.
Call setVideoSize before video view is shown, you can get video size from thumbnail extracted from video.
So that, when video view's onMeasure is called, both mVideoWidth & mVideoHeight are > 0.
If you want to account the height of controllers, you can do it yourself in the onMeasure method.
Hope will help.
public class MyVideoView extends VideoView {
private int mVideoWidth;
private int mVideoHeight;
public MyVideoView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyVideoView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public MyVideoView(Context context) {
super(context);
}
public void setVideoSize(int width, int height) {
mVideoWidth = width;
mVideoHeight = height;
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Log.i("###", "onMeasure");
int width = getDefaultSize(mVideoWidth, widthMeasureSpec);
int height = getDefaultSize(mVideoHeight, heightMeasureSpec);
if (mVideoWidth > 0 && mVideoHeight > 0) {
if (mVideoWidth * height > width * mVideoHeight) {
// Log.i("###", "image too tall, correcting");
height = width * mVideoHeight / mVideoWidth;
} else if (mVideoWidth * height < width * mVideoHeight) {
// Log.i("###", "image too wide, correcting");
width = height * mVideoWidth / mVideoHeight;
} else {
// Log.i("###", "aspect ratio is correct: " +
// width+"/"+height+"="+
// mVideoWidth+"/"+mVideoHeight);
}
}
// Log.i("###", "setting size: " + width + 'x' + height);
setMeasuredDimension(width, height);
}
}

I solved this problem with layout. It seems that it worked fine when it was pinned to the corners but it caused the video to skew. To test I changed my relative layout's background to #990000 to see the red poking through.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/relative_parent"
android:background="#000000">
<VideoView
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:focusable="false"
android:focusableInTouchMode="false"
android:id="#+id/videoView" />
</RelativeLayout>

Regarding question 1, I am surprised no one has mentioned the possible use of the MediaPlayer's scaling mode.
https://developer.android.com/reference/android/media/MediaPlayer.html#setVideoScalingMode(int)
It has 2 modes. Both of them always fill the view area. To get it to fill the space while preserving the aspect ratio, thus cropping the long side, you need to switch to the second mode, VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING. That solves one part of the problem. The other part is to change VideoView's measuring behavior, just as some of the other answers demonstrate. This is the way I did it, mostly out of laziness and not familiar with the metadata API's that the others use, you are welcome to use this method or one of the other methods to fix the size of the view. The blanket catch ensures safety when this is called before mMediaPlayer exists, as it may be called many times, and also falls back to old behavior should the field name ever change.
class FixedSizeVideoView : VideoView {
constructor(ctx: Context) : super(ctx)
constructor(ctx: Context, attrs: AttributeSet) : super(ctx, attrs)
// rather than shrink down to fit, stay at the size requested by layout params. Let the scaling mode
// of the media player shine through. If the scaling mode on the media player is set to the one
// with cropping, you can make a player similar to AVLayerVideoGravityResizeAspectFill on iOS
override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) {
try {
val mpField = VideoView::class.java.getDeclaredField("mMediaPlayer")
mpField.isAccessible = true
val mediaPlayer: MediaPlayer = mpField.get(this) as MediaPlayer
val width = View.getDefaultSize(mediaPlayer.videoWidth, widthMeasureSpec)
val height = View.getDefaultSize(mediaPlayer.videoHeight, heightMeasureSpec)
setMeasuredDimension(width, height)
}
catch (ex: Exception) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec)
}
}
}
So using this class in the layout, you just change the scaling mode on the media Player wherever you have a chance. Such as:
video.setOnPreparedListener { mp: MediaPlayer ->
mp.setVideoScalingMode(MediaPlayer.VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING)
mp.isLooping = true
mp.setScreenOnWhilePlaying(false)
}
video.start()

public class MyVideoView extends VideoView {
private int mVideoWidth;
private int mVideoHeight;
public MyVideoView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyVideoView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public MyVideoView(Context context) {
super(context);
}
#Override
public void setVideoURI(Uri uri) {
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource(this.getContext(), uri);
mVideoWidth = Integer.parseInt(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_WIDTH));
mVideoHeight = Integer.parseInt(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_HEIGHT));
super.setVideoURI(uri);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Log.i("###", "onMeasure");
int width = getDefaultSize(mVideoWidth, widthMeasureSpec);
int height = getDefaultSize(mVideoHeight, heightMeasureSpec);
if (mVideoWidth > 0 && mVideoHeight > 0) {
if (mVideoWidth * height > width * mVideoHeight) {
// Log.i("###", "image too tall, correcting");
height = width * mVideoHeight / mVideoWidth;
} else if (mVideoWidth * height < width * mVideoHeight) {
// Log.i("###", "image too wide, correcting");
width = height * mVideoWidth / mVideoHeight;
} else {
// Log.i("###", "aspect ratio is correct: " +
// width+"/"+height+"="+
// mVideoWidth+"/"+mVideoHeight);
}
}
// Log.i("###", "setting size: " + width + 'x' + height);
setMeasuredDimension(width, height);
}
}

Quick and efficient fix:
No need to create a custom view extending from VideoView. Just set a value big enough to android:layout_width. This will set the widthSpecMode of the video view to View.MeasureSpec.AT_MOST and then the onMeasure() method of VideoView will auto-adjust its width keeping the ratio.
<VideoView
android:id="#+id/video"
android:layout_width="2000dp"
android:layout_height="match_parent" />

Using ConstraintLayout we can achieve this, refer below xml code.
When layout_width and layout_height are 0dp, the size and position of the VideoView are calculated dynamically based on the other constraints. The layout_constraintDimensionRatio attribute indicates that when the app calculates the size of the VideoView, the ratio of the width to the height should be 3:4. This constraint keeps the aspect ratio of the video the same and prevents the view from being stretched too far in either direction (depending on how the device is rotated).
Change layout_constraintDimensionRatio value depending on requirement Portrait/Landscape.
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<VideoView
android:id="#+id/videoView"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintDimensionRatio="3:4"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

For the first time a question answered my issue instead of answers!!
My issue was that I had a white space under the video on full screen. I was setting the layout_height to match_parent. The solution was to set it to wrap_content and give the parent a black background. That, and having the VideoView centered vertically in its parent.
I wrote this as a comment but then thought someone might have the same
issue I had, so here it is as an answer also.

I've tried a lot of solutions, while my video was always in 1000*1000 format, so I've created an easy solution for people who know their aspect ratio. First create a VideoView in a RelativeLayout like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/video_holder"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:clipToPadding="false">
<VideoView
android:id="#+id/videoView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true" />
</RelativeLayout>
Then before you load the video change the height and with programmatically like this:
int i = videoView.getHeight() > videoView.getWidth() ? videoView.getHeight() : videoView.getWidth();
video_holder.setLayoutParams(new ConstraintLayout.LayoutParams(i, i));
Of course this only works with 1:1 aspect ratio's but you could just use your aspect ratio to change either the height or the width.

Jobbert's answer in Kotlin, in case anyone needs it:
val max = if (videoView.height > videoView.width) videoView.height else videoView.width
videoView.layoutParams = ConstraintLayout.LayoutParams(max, max)

I have been looking for ways to display video in aspect fill in VideoView but after trying many solutions, none of them seems to work.
So I implemented the following approach and it's working for me:
Code:
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// getting screen size
((Activity) getContext()).getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int width = displayMetrics.widthPixels;
int height = displayMetrics.heightPixels;
double videoSizeRatio = (double) mVideoHeight / mVideoWidth;
double screenSizeRatio = (double) height / width;
if (mVideoWidth > 0 && mVideoHeight > 0) {
if (videoSizeRatio > screenSizeRatio) { // screen is wider than video width
height = (int) (videoSizeRatio * width);
} else if (videoSizeRatio < screenSizeRatio) {
width = (int) (height / videoSizeRatio);
}
}
setMeasuredDimension(width, height);
}
Layout:
<YourCustomizedVideoView
android:id="#+id/videoView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
/>

The best way to do so is
Set width of videoview to max
I was facing the same issue.
I just set the Width to 999px
and Height to match parent
It works.
We get a perfect view like Tik tok or Instagram reels

Just put your VideoView inside the RelativeLayout and set the desired size for that relative layout. like below code,
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="300dp">
<VideoView
android:id="#+id/videoView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true" />
</RelativeLayout>
It will work.

You just need to put Videoview widget in RelativeLayout (changes in xml file only)

Allocate fixed space for adaptive banner ad

How should I go about allocating fixed space for adaptive ad banners?
My XML adaptive banner
<FrameLayout
android:id="#+id/ad_view_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_alignParentBottom="true"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
/>
Inside my Fragment getting adaptive ad banner dimensions
private val adSize: AdSize
get() {
val outMetrics = Resources.getSystem().displayMetrics;
val density = outMetrics.density
var adWidthPixels = adContainerView.width.toFloat()
if (adWidthPixels == 0f) {
adWidthPixels = outMetrics.widthPixels.toFloat()
}
val adWidth = (adWidthPixels / density).toInt()
return AdSize.getCurrentOrientationBannerAdSizeWithWidth(context, adWidth)
}
I would like to follow Googles guidlines and have an allocated fixed space reserved for my banner, so that if my banner "lags" for a second screen on mobile stays the same.
How should I go about it, whats the proper way?

when starting the app you can get the adaptive banner height straight away by calling something like adSize.getHeight(). This will give you banner height in dps.
You then convert that heigth dps in px and set this height to your ad frame layout programatically by calling setLayoutParams with acquired height in pixels.
This way you dont need to wait for the ad to load to apply proper height and risk ad overlapping policy violation or conent shifting (which would happen if you depend on wrap_content)

If you have a more complex behavior, like I do, you can use the following implementation. I have a ConstraintLayout that splits my screen in two parts in portrait mode. The banner is within one of these two parts and the ratio between them is not fixed but depending on some logic. So this implementation also works with that requirement, as it overwrites onMeasure to determine the best size depending on the available width.
public class AdBanner extends FrameLayout
{
private AdView mAdView;
private final DisplayMetrics mDisplayMetrics = new DisplayMetrics();
public AdBanner(Context context)
{
super(context);
}
public AdBanner(Context context, AttributeSet attrs)
{
super(context, attrs);
}
public AdBanner(Context context, AttributeSet attrs, int defStyleAttr)
{
super(context, attrs, defStyleAttr);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
if (!isShowBanner())
{
super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.AT_MOST));
return;
}
int width = MeasureSpec.getSize(widthMeasureSpec);
if (width <= 0)
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
return;
}
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
// That's where we determine the most accurate banner format.
AdSize adSize = AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(getContext(), getDpWidth(width));
int height = adSize.getHeightInPixels(getContext());
int heightMode = MeasureSpec.getMode(heightMeasureSpec);
if (heightMode != MeasureSpec.UNSPECIFIED)
{
height = Math.min(height, MeasureSpec.getSize(heightMeasureSpec));
}
setMeasuredDimension(widthMeasureSpec, MeasureSpec.makeMeasureSpec(height, MeasureSpec.getMode(heightMeasureSpec)));
}
protected int getDpWidth(int width)
{
Display display = ((WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
display.getMetrics(mDisplayMetrics);
return (int) (width / mDisplayMetrics.density);
}
protected boolean isShowBanner()
{
// Do your checks here, like whether the user payed for ad removement.
}
#Override
protected void onLayout(boolean changed, int l, int t, int r, int b)
{
if (!isShowBanner())
{
return;
}
int width = r - l;
if (width <= 0)
{
return;
}
AdSize adSize = AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(getContext(), getDpWidth(width));
// Prevent the ad from beeing added with each layout cicle,
// by checking, whether or not available size actually changed the format of the banner
if (mAdView == null || !adSize.equals(mAdView.getAdSize()))
{
removeAllViews();
mAdView = new AdView(getContext());
mAdView.setAdSize(adSize);
((GameApplication) getContext().getApplicationContext()).androidInjector().getAdService().loadBannerAd(getRootActivity(this), mAdView);
this.addView(mAdView);
}
mAdView.layout(0, 0, width, b - t);
}
}

View doesn't fill the whole screen

I'm having everything the same as in this sample in https://github.com/googlesamples/android-vision/tree/master/visionSamples/multi-tracker except my activity layout is this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/topLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:keepScreenOn="true"
android:weightSum="100"
android:orientation="horizontal">
<be.citylife.communitypurchaseapp.view.camera.CameraSourcePreview
android:id="#+id/preview"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="60">
<be.citylife.communitypurchaseapp.view.camera.GraphicOverlay
android:id="#+id/overlay"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</be.citylife.communitypurchaseapp.view.camera.CameraSourcePreview>
<FrameLayout
android:id="#+id/sideContainer"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="40"/>
</LinearLayout>
My tablet is in landscape and I want that the cameraPreviewSource is always left and fills the whole screen in the height and then right off it I'm having a fragment that fills the rest.
This layout works except my previewsource doesn't fill the whole height. It has a black banner on it. Even my width is actually smaller than I want you can see this on the screenshot:
http://i61.tinypic.com/vctmw0.png
I played with the CameraSourcePreview with the width and height in the onLayout function but it doesn't help. I know on the preview that it does fill the screen to the bottom of the screen but on the tablet it isn't.
lp.
Anyone an idea how to solve this?
EDIT:
I think it has something to do with this:
#Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
int width = 320;
int height = 240;
if (mCameraSource != null) {
Size size = mCameraSource.getPreviewSize();
if (size != null) {
width = size.getWidth();
height = size.getHeight();
}
}
// Swap width and height sizes when in portrait, since it will be rotated 90 degrees
if (isPortraitMode()) {
int tmp = width;
width = height;
height = tmp;
}
final int layoutWidth = right - left;
final int layoutHeight = bottom - top;
// Computes height and width for potentially doing fit width.
int childWidth = layoutWidth;
int childHeight = (int)(((float) layoutWidth / (float) width) * height);
// If height is too tall using fit width, does fit height instead.
if (childHeight > layoutHeight) {
childHeight = layoutHeight;
childWidth = (int)(((float) layoutHeight / (float) height) * width);
}
for (int i = 0; i < getChildCount(); ++i) {
getChildAt(i).layout(0, 0, childWidth, childHeight);
}
try {
startIfReady();
} catch (IOException e) {
Log.e(TAG, "Could not start camera source.", e);
}
}
That's the onlayout method off the CameraSourcePreview.

Comment or remove below lines from CameraSourcePreview and it should be fine. I was having same issue like you and it is solved now.
if (childHeight > layoutHeight) {
childHeight = layoutHeight;
childWidth = (int)(((float) layoutHeight / (float) height) * width);
}

that should put it into fullscreen mode :D there are a bunch of other modes you can select from. if this doesnt work, remove the automatically generated
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
/** gets called when a Menu.onClick happens
*
* #param item the ID of the clicked Item
*/
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
int id = item.getItemId();
if (id == R.id.action_settings) {
//TODO
}
return super.onOptionsItemSelected(item);
}
}

Likely has something to do with the aspect ratio of the camera and how it draws into its container.
If the camera preview you're using maintains aspect ratio and fits the preview to the container, then you will definitely get black bars. This is because most cameras' sensors produce images that are designed to fit within a space relative to 1920x1080px (or a 16:9 aspect ratio box).
What you need, is for the extra space on the sides to be hidden and for the preview to fill based on height. That is, if you don't mind some of your image to be hidden from the user when previewing. It might not be possible to do this directly with the view you're using, but it should be relatively simple if you place your object into another layout container.
Hope this helps!

Scale Image to fill ImageView width and keep aspect ratio

I have a GridView. The data of GridView is request from a server.
Here is the item layout in GridView:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/analysis_micon_bg"
android:gravity="center_horizontal"
android:orientation="vertical"
android:paddingBottom="#dimen/half_activity_vertical_margin"
android:paddingLeft="#dimen/half_activity_horizontal_margin"
android:paddingRight="#dimen/half_activity_horizontal_margin"
android:paddingTop="#dimen/half_activity_vertical_margin" >
<ImageView
android:id="#+id/ranking_prod_pic"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:contentDescription="#string/app_name"
android:scaleType="centerCrop" />
<TextView
android:id="#+id/ranking_rank_num"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/ranking_prod_num"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/ranking_prod_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
I request data from server, get image url and load image to Bitmap
public static Bitmap loadBitmapFromInputStream(InputStream is) {
return BitmapFactory.decodeStream(is);
}
public static Bitmap loadBitmapFromHttpUrl(String url) {
try {
return loadBitmapFromInputStream((InputStream) (new URL(url).getContent()));
} catch (Exception e) {
Log.e(TAG, e.getMessage());
return null;
}
}
and there is the code of getView(int position, View convertView, ViewGroup parent) method in adapter
Bitmap bitmap = BitmapUtil.loadBitmapFromHttpUrl(product.getHttpUrl());
prodImg.setImageBitmap(bitmap);
The image size is 210*210. I run my application on my Nexus 4. The image does fill ImageView width, but the ImageView height does not scale. ImageView does not show the whole image.
How do I solve this problem?

Without using any custom classes or libraries:
<ImageView
android:id="#id/img"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitCenter" />
scaleType="fitCenter" (default when omitted)
will make it as wide as the parent allows and up/down-scale as needed keeping aspect ratio.
scaleType="centerInside"
if the intrinsic width of src is smaller than parent widthwill center the image horizontally
if the intrinsic width of src is larger than parent widthwill make it as wide as the parent allows and down-scale keeping aspect ratio.
It doesn't matter if you use android:src or ImageView.setImage* methods and the key is probably the adjustViewBounds.

I like answer of arnefm but he made a small mistake (see comments) which I will try to correct:
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;
/**
* ImageView that keeps aspect ratio when scaled
*/
public class ScaleImageView extends ImageView {
public ScaleImageView(Context context) {
super(context);
}
public ScaleImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ScaleImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
try {
Drawable drawable = getDrawable();
if (drawable == null) {
setMeasuredDimension(0, 0);
} else {
int measuredWidth = MeasureSpec.getSize(widthMeasureSpec);
int measuredHeight = MeasureSpec.getSize(heightMeasureSpec);
if (measuredHeight == 0 && measuredWidth == 0) { //Height and width set to wrap_content
setMeasuredDimension(measuredWidth, measuredHeight);
} else if (measuredHeight == 0) { //Height set to wrap_content
int width = measuredWidth;
int height = width * drawable.getIntrinsicHeight() / drawable.getIntrinsicWidth();
setMeasuredDimension(width, height);
} else if (measuredWidth == 0){ //Width set to wrap_content
int height = measuredHeight;
int width = height * drawable.getIntrinsicWidth() / drawable.getIntrinsicHeight();
setMeasuredDimension(width, height);
} else { //Width and height are explicitly set (either to match_parent or to exact value)
setMeasuredDimension(measuredWidth, measuredHeight);
}
}
} catch (Exception e) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
}
Thus your ImageView will be scaled properly and will have no dimension problems if (for instance) put inside of ScrollView

I had a similar problem once. I solved it by making a custom ImageView.
public class CustomImageView extends ImageView
Then override the onMeasure method of the imageview. I did something like this I believe:
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
try {
Drawable drawable = getDrawable();
if (drawable == null) {
setMeasuredDimension(0, 0);
} else {
float imageSideRatio = (float)drawable.getIntrinsicWidth() / (float)drawable.getIntrinsicHeight();
float viewSideRatio = (float)MeasureSpec.getSize(widthMeasureSpec) / (float)MeasureSpec.getSize(heightMeasureSpec);
if (imageSideRatio >= viewSideRatio) {
// Image is wider than the display (ratio)
int width = MeasureSpec.getSize(widthMeasureSpec);
int height = (int)(width / imageSideRatio);
setMeasuredDimension(width, height);
} else {
// Image is taller than the display (ratio)
int height = MeasureSpec.getSize(heightMeasureSpec);
int width = (int)(height * imageSideRatio);
setMeasuredDimension(width, height);
}
}
} catch (Exception e) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
This will stretch the image to fit the screen while maintaining the aspect ratio.

Use android:scaleType="centerCrop".

FOR IMAGE VIEW (set these parameters)
android:layout_width = "match_parent"
android:layout_height = "wrap_content"
android:scaleType = "fitCenter"
android:adjustViewBounds = "true"
Now whatever the size of the image is there, it's width will match the parent and height will be according to match the ratio. I have tested this and I am 100% sure.
we want this -->
not this -->
// Results will be:
Image width -> stretched as match parent
Image height -> according to image width (maximum to aspect ratio)
// like the first one

I did something similar to the above and then banged my head against the wall for a few hours because it did not work inside a RelativeLayout. I ended up with the following code:
package com.example;
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;
public class ScaledImageView extends ImageView {
public ScaledImageView(final Context context, final AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec) {
final Drawable d = getDrawable();
if (d != null) {
int width;
int height;
if (MeasureSpec.getMode(heightMeasureSpec) == MeasureSpec.EXACTLY) {
height = MeasureSpec.getSize(heightMeasureSpec);
width = (int) Math.ceil(height * (float) d.getIntrinsicWidth() / d.getIntrinsicHeight());
} else {
width = MeasureSpec.getSize(widthMeasureSpec);
height = (int) Math.ceil(width * (float) d.getIntrinsicHeight() / d.getIntrinsicWidth());
}
setMeasuredDimension(width, height);
} else {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
}
And then to prevent RelativeLayout from ignoring the measured dimension I did this:
<FrameLayout
android:id="#+id/image_frame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/something">
<com.example.ScaledImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="150dp"/>
</FrameLayout>

This will not be applicable if you set image as background in ImageView, need to set at src(android:src).
Thanks.

Yo don't need any java code. You just have to :
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="centerCrop" />
The key is in the match parent for width and height

To create an image with width equals screen width, and height proportionally set according to aspect ratio, do the following.
Glide.with(context).load(url).asBitmap().into(new SimpleTarget<Bitmap>() {
#Override
public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
// creating the image that maintain aspect ratio with width of image is set to screenwidth.
int width = imageView.getMeasuredWidth();
int diw = resource.getWidth();
if (diw > 0) {
int height = 0;
height = width * resource.getHeight() / diw;
resource = Bitmap.createScaledBitmap(resource, width, height, false);
}
imageView.setImageBitmap(resource);
}
});
Hope this helps.

Use these properties in ImageView to keep aspect ratio:
android:adjustViewBounds="true"
android:scaleType="fitXY"

You can try to do what you're doing by manually loading the images, but I would very very strongly recommend taking a look at Universal Image Loader.
I recently integrated it into my project and I have to say its fantastic. Does all the worrying about making things asynchronous, resizing, caching images for you. It's really easy to integrate and set up. Within 5 minutes you can probably get it doing what you want.
Example code:
//ImageLoader config
DisplayImageOptions displayimageOptions = new DisplayImageOptions.Builder().showStubImage(R.drawable.downloadplaceholder).cacheInMemory().cacheOnDisc().showImageOnFail(R.drawable.loading).build();
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext()).
defaultDisplayImageOptions(displayimageOptions).memoryCache(new WeakMemoryCache()).discCache(new UnlimitedDiscCache(cacheDir)).build();
if (ImageLoader.getInstance().isInited()) {
ImageLoader.getInstance().destroy();
}
ImageLoader.getInstance().init(config);
imageLoadingListener = new ImageLoadingListener() {
#Override
public void onLoadingStarted(String s, View view) {
}
#Override
public void onLoadingFailed(String s, View view, FailReason failReason) {
ImageView imageView = (ImageView) view;
imageView.setImageResource(R.drawable.android);
Log.i("Failed to Load " + s, failReason.toString());
}
#Override
public void onLoadingComplete(String s, View view, Bitmap bitmap) {
}
#Override
public void onLoadingCancelled(String s, View view) {
}
};
//Imageloader usage
ImageView imageView = new ImageView(getApplicationContext());
if (orientation == 1) {
imageView.setLayoutParams(new LinearLayout.LayoutParams(width / 6, width / 6));
} else {
imageView.setLayoutParams(new LinearLayout.LayoutParams(height / 6, height / 6));
}
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageLoader.displayImage(SERVER_HOSTNAME + "demos" + demo.getPathRoot() + demo.getRootName() + ".png", imageView, imageLoadingListener);
This can lazy load the images, fit them correctly to the size of the imageView showing a placeholder image while it loads, and showing a default icon if loading fails and caching the resources.
-- I should also add that this current config keeps the image aspect ratio, hence applicable to your original question

Try this: it solved the problem for me
android:adjustViewBounds="true"
android:scaleType="fitXY"

Just use UniversalImageLoader and set
DisplayImageOptions.Builder()
.imageScaleType(ImageScaleType.EXACTLY_STRETCHED)
.build();
and no scale settings on ImageView

try with this simple line... add this line in your xml code in image view tag with out adding any dependency
android:scaleType="fitXY"

use android:ScaleType="fitXY" im ImageView xml

I had a similar issue, I found the reason for this is because you need to calculate the dp. Android studio is calculating the ImageView when you load it from the drawable, but when you are using another method, like loading from bitmap the dp is not automatically accounted for,
Here is my xml
<ImageView
android:id="#+id/imageViewer"
android:layout_width="match_parent"
android:layout_height="match_parent"//dp is not automaticly updated, when loading from a other source
android:scaleType="fitCenter"
tools:srcCompat="#drawable/a8" />
I'm using Kotlin, and loading drawable from an asset file, here's how I calculate this
val d = Drawable.createFromStream(assets.open("imageData/${imageName}.png"), null)
bitHeight = d.minimumHeight//get the image height
imageViewer.layoutParams.height = (bitHeight * resources.displayMetrics.density).toInt()//set the height
imageViewer.setImageDrawable(d)//set the image from the drawable
imageViewer.requestLayout()//here I apply it to the layout

Android: Mediaplayer: How to use SurfaceView or mediaplayer to play video in correct size

I am playing local video file using MediaPlayer and SurfaceView. SurfaceView is the only control in activity, while my video files are QVGA or other. Problem is that video is getting stretched, How can i play video in its original size e.g. qvga with remaining area black.
From iteration,
When i am forcefully sets layout_height/width of Surfaceview in XML, video displayed fine.
surface_holder.setFixedSize(w,h) has no effect, neither mp.setdisplay().
Please guide in this.
UPDATE
XML flie
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/home_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<SurfaceView
android:id="#+id/surface"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="10dip" />
</framelayout>
MediaPlayer usage is as per following link
http://davanum.wordpress.com/2007/12/29/android-videomusic-player-sample-from-local-disk-as-well-as-remote-urls/
Thanks in advance.

Setting your SurfaceView layout to wrap_content will not size a video to play at the proper aspect ratio.
A SurfaceView is an optimized drawing surface
A video is drawn to a SurfaceView, not contained within it
wrap_content is synonymous with fill_parent for a SurfaceView.
What you want to do is get the dimensions of your video from the MediaPlayer object. You can then set the aspect ratio of the SurfaceView to match the video.
Some Basic initialization
public class YourMovieActivity extends Activity implements SurfaceHolder.Callback {
private MediaPlayer mp = null;
//...
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mp = new MediaPlayer();
mSurfaceView = (SurfaceView) findViewById(R.id.surface);
//...
}
}
Then the good stuff. I have omitted error checking here to reduce code, MediaPlayer calls should be wrapped in a try{}.
#Override
public void surfaceCreated(SurfaceHolder holder) {
mp.setDataSource("/sdcard/someVideo.mp4");
mp.prepare();
//Get the dimensions of the video
int videoWidth = mp.getVideoWidth();
int videoHeight = mp.getVideoHeight();
//Get the width of the screen
int screenWidth = getWindowManager().getDefaultDisplay().getWidth();
//Get the SurfaceView layout parameters
android.view.ViewGroup.LayoutParams lp = mSurfaceView.getLayoutParams();
//Set the width of the SurfaceView to the width of the screen
lp.width = screenWidth;
//Set the height of the SurfaceView to match the aspect ratio of the video
//be sure to cast these as floats otherwise the calculation will likely be 0
lp.height = (int) (((float)videoHeight / (float)videoWidth) * (float)screenWidth);
//Commit the layout parameters
mSurfaceView.setLayoutParams(lp);
//Start video
mp.start();
}
Note that this code makes some assumptions about the dimensions of your video. As-is, it maximizes the width and assumes that the height is not greater than the height of the screen.
You may want to fit height instead of width, also you could check the dimension calculation and ensure that it is not greater than the screen or screen - other_layout_elements.

here is the code I currently use in a project:
private MediaPlayer mMediaPlayer;
private SurfaceView mSurfaceView;
private SurfaceHolder holder;
private int mPos = 0;
...
int width = mSurfaceView.getWidth();
int height = mSurfaceView.getHeight();
float boxWidth = width;
float boxHeight = height;
float videoWidth = mMediaPlayer.getVideoWidth();
float videoHeight = mMediaPlayer.getVideoHeight();
Log.i(TAG, String.format("startVideoPlayback # %d - video %dx%d - box %dx%d", mPos, (int) videoWidth, (int) videoHeight, width, height));
float wr = boxWidth / videoWidth;
float hr = boxHeight / videoHeight;
float ar = videoWidth / videoHeight;
if (wr > hr)
width = (int) (boxHeight * ar);
else
height = (int) (boxWidth / ar);
Log.i(TAG, String.format("Scaled to %dx%d", width, height));
holder.setFixedSize(width, height);
mMediaPlayer.seekTo(mPos);
mMediaPlayer.start();
the layout I'm using (you can just ignore the progress bar)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical" >
<ProgressBar
android:id="#+id/progressBar1"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<SurfaceView
android:id="#+id/surface"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" >
</SurfaceView>

On your SurfaceView in XML are you using wrap_content ? This should fix your problem if not. You may need to paste a little more code for further investigation if that doesn't fix your problem.
Change your surface view width to wrap_content as well.

Android: Scale a Drawable or background image?

On a layout I want to scale the background image (keeping its aspect ratio) to the space allocated when the page gets created. Does anyone have an idea how to do this?
I am using layout.setBackgroundDrawable() and a BitmapDrawable() to set gravity for clipping and filling, but don't see any option for scaling.

To customize background image scaling create a resource like this:
<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="center"
android:src="#drawable/list_bkgnd" />
Then it will be centered in the view if used as background. There are also other flags: http://developer.android.com/guide/topics/resources/drawable-resource.html

Haven't tried to do exactly what you want, but you can scale an ImageView using android:scaleType="fitXY"
and it will be sized to fit into whatever size you give the ImageView.
So you could create a FrameLayout for your layout, put the ImageView inside it, and then whatever other content you need in the FrameLayout as well w/ a transparent background.
<FrameLayout
android:layout_width="fill_parent" android:layout_height="fill_parent">
<ImageView
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:src="#drawable/back" android:scaleType="fitXY" />
<LinearLayout>your views</LinearLayout>
</FrameLayout>

There is an easy way to do this from the drawable:
your_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#color/bg_color"/>
<item>
<bitmap
android:gravity="center|bottom|clip_vertical"
android:src="#drawable/your_image" />
</item>
</layer-list>
The only downside is that if there is not enough space, your image won't be fully shown, but it will be clipped, I couldn't find an way to do this directly from a drawable. But from the tests I did it works pretty well, and it doesn't clip that much of the image. You could play more with the gravity options.
Another way will be to just create an layout, where you will use an ImageView and set the scaleType to fitCenter.

Use image as background sized to layout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/imgPlaylistItemBg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:maxHeight="0dp"
android:scaleType="fitXY"
android:src="#drawable/img_dsh" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>

To keep the aspect ratio you have to use android:scaleType=fitCenter or fitStart etc. Using fitXY will not keep the original aspect ratio of the image!
Note this works only for images with a src attribute, not for the background image.

When you set the Drawable of an ImageView by using the setBackgroundDrawable method, the image will always be scaled. Parameters as adjustViewBounds or different ScaleTypes will just be ignored. The only solution to keep the aspect ratio I found, is to resize the ImageView after loading your drawable. Here is the code snippet I used:
// bmp is your Bitmap object
int imgHeight = bmp.getHeight();
int imgWidth = bmp.getWidth();
int containerHeight = imageView.getHeight();
int containerWidth = imageView.getWidth();
boolean ch2cw = containerHeight > containerWidth;
float h2w = (float) imgHeight / (float) imgWidth;
float newContainerHeight, newContainerWidth;
if (h2w > 1) {
// height is greater than width
if (ch2cw) {
newContainerWidth = (float) containerWidth;
newContainerHeight = newContainerWidth * h2w;
} else {
newContainerHeight = (float) containerHeight;
newContainerWidth = newContainerHeight / h2w;
}
} else {
// width is greater than height
if (ch2cw) {
newContainerWidth = (float) containerWidth;
newContainerHeight = newContainerWidth / h2w;
} else {
newContainerWidth = (float) containerHeight;
newContainerHeight = newContainerWidth * h2w;
}
}
Bitmap copy = Bitmap.createScaledBitmap(bmp, (int) newContainerWidth, (int) newContainerHeight, false);
imageView.setBackgroundDrawable(new BitmapDrawable(copy));
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(params);
imageView.setMaxHeight((int) newContainerHeight);
imageView.setMaxWidth((int) newContainerWidth);
In the code snippet above is bmp the Bitmap object that is to be shown and imageView is the ImageView object
An important thing to note is the change of the layout parameters. This is necessary because setMaxHeight and setMaxWidth will only make a difference if the width and height are defined to wrap the content, not to fill the parent. Fill parent on the other hand is the desired setting at the beginning, because otherwise containerWidth and containerHeight will both have values equal to 0.
So, in your layout file you will have something like this for your ImageView:
...
<ImageView android:id="#+id/my_image_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
...

This is not the most performant solution, but as somebody suggested instead of background you can create FrameLayout or RelativeLayout and use ImageView as pseudo background - other elements will be position simply above it:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent">
<ImageView
android:id="#+id/ivBackground"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:scaleType="fitStart"
android:src="#drawable/menu_icon_exit" />
<Button
android:id="#+id/bSomeButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="61dp"
android:layout_marginTop="122dp"
android:text="Button" />
</RelativeLayout>
The problem with ImageView is that only scaleTypes available are:
CENTER, CENTER_CROP, CENTER_INSIDE, FIT_CENTER,FIT_END, FIT_START, FIT_XY, MATRIX
(http://etcodehome.blogspot.de/2011/05/android-imageview-scaletype-samples.html)
and to "scale the background image (keeping its aspect ratio)" in some cases, when you want an image to fill the whole screen (for example background image) and aspect ratio of the screen is different than image's, the necessary scaleType is kind of TOP_CROP, because:
CENTER_CROP centers the scaled image instead of aligning the top edge to the top edge of the image view and FIT_START fits the screen height and not fill the width. And as user Anke noticed FIT_XY doesn't keep aspect ratio.
Gladly somebody has extended ImageView to support TOP_CROP
public class ImageViewScaleTypeTopCrop extends ImageView {
public ImageViewScaleTypeTopCrop(Context context) {
super(context);
setup();
}
public ImageViewScaleTypeTopCrop(Context context, AttributeSet attrs) {
super(context, attrs);
setup();
}
public ImageViewScaleTypeTopCrop(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setup();
}
private void setup() {
setScaleType(ScaleType.MATRIX);
}
#Override
protected boolean setFrame(int frameLeft, int frameTop, int frameRight, int frameBottom) {
float frameWidth = frameRight - frameLeft;
float frameHeight = frameBottom - frameTop;
if (getDrawable() != null) {
Matrix matrix = getImageMatrix();
float scaleFactor, scaleFactorWidth, scaleFactorHeight;
scaleFactorWidth = (float) frameWidth / (float) getDrawable().getIntrinsicWidth();
scaleFactorHeight = (float) frameHeight / (float) getDrawable().getIntrinsicHeight();
if (scaleFactorHeight > scaleFactorWidth) {
scaleFactor = scaleFactorHeight;
} else {
scaleFactor = scaleFactorWidth;
}
matrix.setScale(scaleFactor, scaleFactor, 0, 0);
setImageMatrix(matrix);
}
return super.setFrame(frameLeft, frameTop, frameRight, frameBottom);
}
}

Now IMHO would be perfect if somebody wrote custom Drawable which scales image like that. Then it could be used as background parameter.
Reflog suggests to prescale drawable before using it. Here is instruction how to do it:
Java (Android): How to scale a drawable without Bitmap?
Although it has disadvantage, that upscaled drawable/bitmap will use more RAM, while scaling on the fly used by ImageView doesn't require more memory. Advantage could be less processor load.

The Below code make the bitmap perfectly with same size of the imageview. Get the bitmap image height and width and then calculate the new height and width with the help of imageview's parameters. That give you required image with best aspect ratio.
int bwidth=bitMap1.getWidth();
int bheight=bitMap1.getHeight();
int swidth=imageView_location.getWidth();
int sheight=imageView_location.getHeight();
new_width=swidth;
new_height = (int) Math.floor((double) bheight *( (double) new_width / (double) bwidth));
Bitmap newbitMap = Bitmap.createScaledBitmap(bitMap1,new_width,new_height, true);
imageView_location.setImageBitmap(newbitMap)

What Dweebo proposed works. But in my humble opinion it is unnecessary.
A background drawable scales well by itself. The view should have fixed width and height, like in the following example:
< RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/black">
<LinearLayout
android:layout_width="500dip"
android:layout_height="450dip"
android:layout_centerInParent="true"
android:background="#drawable/my_drawable"
android:orientation="vertical"
android:padding="30dip"
>
...
</LinearLayout>
< / RelativeLayout>

One option to try is to put the image in the drawable-nodpi folder and set background of a layout to the drawable resource id.
This definitely works with scaling down, I haven't tested with scaling up though.

Kotlin:
If you needed to draw a bitmap in a View, scaled to FIT.
You can do the proper calculations to set bm the height equal to the container and adjust width, in the case bm width to height ratio is less than container width to height ratio, or the inverse in the opposite scenario.
Images:
// binding.fragPhotoEditDrawCont is the RelativeLayout where is your view
// bm is the Bitmap
val ch = binding.fragPhotoEditDrawCont.height
val cw = binding.fragPhotoEditDrawCont.width
val bh = bm.height
val bw = bm.width
val rc = cw.toFloat() / ch.toFloat()
val rb = bw.toFloat() / bh.toFloat()
if (rb < rc) {
// Bitmap Width to Height ratio is less than Container ratio
// Means, bitmap should pin top and bottom, and have some space on sides.
// _____ ___
// container = |_____| bm = |___|
val bmHeight = ch - 4 //4 for container border
val bmWidth = rb * bmHeight //new width is bm_ratio * bm_height
binding.fragPhotoEditDraw.layoutParams = RelativeLayout.LayoutParams(bmWidth.toInt(), bmHeight)
}
else {
val bmWidth = cw - 4 //4 for container border
val bmHeight = 1f/rb * cw
binding.fragPhotoEditDraw.layoutParams = RelativeLayout.LayoutParams(bmWidth, bmHeight.toInt())
}

you'll have to pre-scale that drawable before you use it as a background

You can use one of following:
android:gravity="fill_horizontal|clip_vertical"
Or
android:gravity="fill_vertical|clip_horizontal"

VideoView to match parent height and keep aspect ratio - android

Jobbert's answer in Kotlin, in case anyone needs it: val max = if (videoView.height > videoView.width) videoView.height else videoView.width videoView.layoutParams = ConstraintLayout.LayoutParams(max, max)

The best way to do so is Set width of videoview to max I was facing the same issue. I just set the Width to 999px and Height to match parent It works. We get a perfect view like Tik tok or Instagram reels

You just need to put Videoview widget in RelativeLayout (changes in xml file only) here is reference answer link
