I have an image loading from a url using Glide, with the image I'm getting the image height. WHen I set the height, and width to match parent, the height is too high and there is empty space on bottom and top of image. The height is in pixels
This is how I'm setting height:
if (height != 0) {
height = convertPixelsToDp(height, mContext);
ViewGroup.LayoutParams params = viewHolder.listphoto.getLayoutParams();
params.height = height;
params.width = ViewGroup.LayoutParams.MATCH_PARENT;
viewHolder.listphoto.setLayoutParams(params);
}
XML:
<ImageView
android:id="#+id/listphoto"
android:adjustViewBounds="true"
android:layout_width="match_parent"
android:background="#dddddd"
android:layout_height="wrap_content"
android:scaleType="fitCenter"
/>
I tried experimenting with adjustViewBounds and scaleType but nothing is working. It's not wrapping the top and bottom. How can I make this work?
I've been working on this all night
UPDATE:
public static float convertPixelsToDp(float px, Context context){
Resources resources = context.getResources();
DisplayMetrics metrics = resources.getDisplayMetrics();
float dp = px / ((float)metrics.densityDpi / DisplayMetrics.DENSITY_DEFAULT);
return dp;
}
Okay. So, the answer is very simple. We just need to change the height of the ImageView with respect to the width of the image and the width of the screen. Doing this will set the image properly in the ImageView:
private float getHeight(float height, float width) {
Display display = ((Activity) context).getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
return (height * size.x / width);
}
If your ImageView has some margin or padding set to it, use this instead:
private float getHeight(float height, float width, int containerHeight) {
return (height * containerHeight / width);
}
Then finally,
if (height != 0) {
height = (int) getHeight(height, width);
//or if has some margin or padding
ViewGroup.LayoutParams params = viewHolder.listphoto.getLayoutParams();
params.height = height;
params.width = ViewGroup.LayoutParams.MATCH_PARENT;
viewHolder.listphoto.setLayoutParams(params);
}
Or if has padding or margin:
if (height != 0) {
height = (int) getHeight(height, width, viewHolder.listphoto.getMeasuredWidth());
ViewGroup.LayoutParams params = viewHolder.listphoto.getLayoutParams();
params.height = height;
params.width = ViewGroup.LayoutParams.MATCH_PARENT;
viewHolder.listphoto.setLayoutParams(params);
}
Note: It will be a better if you go with the second one. It will ensure that even when you apply some margin/padding to your ImageView, the image sets properly in the ImageView ignoring the padding/margin.
add these attributes
android:adjustViewBounds="true"
android:cropToPadding="false"
android:scaleType="fitXY"
android:scaleType="fitXY"
android:adjustViewBounds="true"
I think these two property will resolve the problem and please remove
android:scaleType="fitCenter"
Change width to
android:layout_width="wrap_content"
android:adjustViewBounds="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
This will work for you without giving scaleType.
I have a layout with a background image. The image width should be the same as the screen width (match_parent). But it's ugly, the OS don't stretch the picture in height.
I heard about ImageView scaleType, so I have the background image in an ImageView instead of a layout background, but I can't config to be what I want.
How can I set to the layout or ImageView to scale the image (in width) to fit the width of the screen AND scale the height with the same scale?
I want the second screen in the picture:
UPDATE:
I'm trying from code, but I get 0 width + I can't believe this can't be done from xml with an ImageView.
Drawable imageDrawable = getResources().getDrawable(imageResource);
contentContainer.setBackgroundDrawable(imageDrawable);
Rect rect = imageDrawable.getBounds();
int originalWidth = rect.width();
int originalHeight = rect.height();
Display display = getActivity().getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = originalHeight * (width/originalWidth);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(width, height);
contentContainer.setLayoutParams(layoutParams);
contentContainer.post(new Runnable() {
#Override
public void run() {
contentContainer.setScaleY(contentContainer.getScaleX());
Rect rect = contentContainer.getBackground().getBounds();
int originalWidth = rect.width();
int originalHeight = rect.height();
Display display = getActivity().getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = originalHeight * (width/originalWidth);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(width, height);
contentContainer.setLayoutParams(layoutParams);
}
}
Use FrameLayout as parent and then add imageview as child.
Give the width match_parent and height fill_parent to the imageView and another ways is apply the android:layout_weight attribute try this may be it's work.
you can do this at runtime by measuring the width of the device like this:--
super.onCreate(savedInstanceState);
setContentView(<layout-resoure-id);
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
int imageSize = 0;
if (width > height)
imageSize = height;
else
imageSize = width;
ImageView imageView = (ImageView) findViewById(R.id.imageView);
imageView.getLayoutParams().width = imageSize;
imageView.getLayoutParams().height = imageSize;
imageView.setImageResource(R.drawable.pattu);
your xml:--
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_margin="10dp"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView"
android:layout_width="100dp"
android:layout_height="100dp"
android:scaleType="fitXY"/>
</LinearLayout>
Enjoy...!
Have you tried playing with scaleType in you layout file?
<ImageView
...
android:scaleType="fitStart"
/>
This should scale your image to fit at the top of your layout, stretching or shrinking if necessary. Haven't had a chance to test (and I can't remember the height/width settings--sorry!), but this could be a solution.
ImageView imageView = (ImageView) findViewById(R.id.your_image_id);
DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
int width = displayMetrics.widthPixels;
int height = displayMetrics.heightPixels;
int imageSize = height>width?width:height;
your configurations go here !
imageView.getLayoutParams().width = imageSize;
imageView.getLayoutParams().height = imageSize + (/* additional height logic*/);
you should put the imageView scaletype as fitXY and do this to stretch the image like the way you want!
<ImageView
...
android:scaleType="fitXY"
/>
Is there anyway so I can align bitmap in ImageView. I have an issue with my image view. I'm setting it's source via Java Code and after bitmap is resized it's centered in ImageView, but the thing that I want is to align the bitmap.
Declaring the imageView :
<RelativeLayout
android:id="#+id/collection_background"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/actionbar" >
<ImageView
android:id="#+id/collection_image_background"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:contentDescription="#string/stampii" />
// countinue ........
and here is how I'm setting the bitmap :
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inTempStorage = new byte[8*1024];
ops = BitmapFactory.decodeStream(cis,null,o2);
ImageView view = (ImageView) findViewById (R.id.collection_image_background);
view.setImageBitmap(ops);
Any ides how to do that?
Add android:scaleType="fitStart" to your ImageView. It is ok for me.
You can use android:scaleType to change the alignement in your ImageView.
You can use setLayoutParams, as shown in this answer.
EDIT
Your problem is that you've specified the view to be as wide as its parent, while the loaded bitmap may be considerably thinner.
Try to make the view only as wide as needed by using this attribute instead:
android:layout_width="wrap_content"
Actually you can scale your bitmap depending on your screen size and set it as source of your ImageView. You can use something like this :
int screenWidth = getWindow().getWindowManager().getDefaultDisplay().getWidth();
Log.e("","screen width : "+screenWidth);
//int screenHeight = getWindow().getWindowManager().getDefaultDisplay().getHeight();
int width = ops.getWidth();
Log.e("","bitmap width : "+width);
int height = ops.getHeight();
Log.e("","bitmap height : "+height);
float scale = 0;
if(width>height){
scale = (float) width / (float) height;
} else if(height>width){
scale = (float) height / (float) width;
}
Log.e("","scale : "+scale);
float newWidth = (float) screenWidth * scale;
Log.d("","new height : "+newWidth);
Bitmap scaledBitmap = Bitmap.createScaledBitmap(ops, screenWidth, (int) newWidth, true);
Log.e("","new bitmap width : "+scaledBitmap.getWidth());
Log.e("","new bitmap height : "+scaledBitmap.getHeight());
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(screenWidth, (int)newWidth);
params.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
view.setLayoutParams(params);
view.setImageBitmap(scaledBitmap);
Try this and just hit me up if it's working or not.
Additionally to the answers above you can set it programmatically with scaleType:
image.scaleType = ImageView.ScaleType.FIT_START
How to fit an image of random size to an ImageView?
When:
Initially ImageView dimensions are 250dp * 250dp
The image's larger dimension should be scaled up/down to 250dp
The image should keep its aspect ratio
The ImageView dimensions should match scaled image's dimensions after scaling
E.g. for an image of 100*150, the image and the ImageView should be 166*250.
E.g. for an image of 150*100, the image and the ImageView should be 250*166.
If I set the bounds as
<ImageView
android:id="#+id/picture"
android:layout_width="250dp"
android:layout_height="250dp"
android:layout_gravity="center_horizontal"
android:layout_marginTop="20dp"
android:adjustViewBounds="true" />
images fit properly in the ImageView, but the ImageView is always 250dp * 250dp.
May not be answer for this specific question, but if someone is, like me, searching for answer how to fit image in ImageView with bounded size (for example, maxWidth) while preserving Aspect Ratio and then get rid of excessive space occupied by ImageView, then the simplest solution is to use the following properties in XML:
android:scaleType="centerInside"
android:adjustViewBounds="true"
(The answer was heavily modified after clarifications to the original question)
After clarifications:
This cannot be done in xml only. It is not possible to scale both the image and the ImageView so that image's one dimension would always be 250dp and the ImageView would have the same dimensions as the image.
This code scales Drawable of an ImageView to stay in a square like 250dp x 250dp with one dimension exactly 250dp and keeping the aspect ratio. Then the ImageView is resized to match the dimensions of the scaled image. The code is used in an activity. I tested it via button click handler.
Enjoy. :)
private void scaleImage(ImageView view) throws NoSuchElementException {
// Get bitmap from the the ImageView.
Bitmap bitmap = null;
try {
Drawable drawing = view.getDrawable();
bitmap = ((BitmapDrawable) drawing).getBitmap();
} catch (NullPointerException e) {
throw new NoSuchElementException("No drawable on given view");
} catch (ClassCastException e) {
// Check bitmap is Ion drawable
bitmap = Ion.with(view).getBitmap();
}
// Get current dimensions AND the desired bounding box
int width = 0;
try {
width = bitmap.getWidth();
} catch (NullPointerException e) {
throw new NoSuchElementException("Can't find bitmap on given view/drawable");
}
int height = bitmap.getHeight();
int bounding = dpToPx(250);
Log.i("Test", "original width = " + Integer.toString(width));
Log.i("Test", "original height = " + Integer.toString(height));
Log.i("Test", "bounding = " + Integer.toString(bounding));
// Determine how much to scale: the dimension requiring less scaling is
// closer to the its side. This way the image always stays inside your
// bounding box AND either x/y axis touches it.
float xScale = ((float) bounding) / width;
float yScale = ((float) bounding) / height;
float scale = (xScale <= yScale) ? xScale : yScale;
Log.i("Test", "xScale = " + Float.toString(xScale));
Log.i("Test", "yScale = " + Float.toString(yScale));
Log.i("Test", "scale = " + Float.toString(scale));
// Create a matrix for the scaling and add the scaling data
Matrix matrix = new Matrix();
matrix.postScale(scale, scale);
// Create a new bitmap and convert it to a format understood by the ImageView
Bitmap scaledBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, true);
width = scaledBitmap.getWidth(); // re-use
height = scaledBitmap.getHeight(); // re-use
BitmapDrawable result = new BitmapDrawable(scaledBitmap);
Log.i("Test", "scaled width = " + Integer.toString(width));
Log.i("Test", "scaled height = " + Integer.toString(height));
// Apply the scaled bitmap
view.setImageDrawable(result);
// Now change ImageView's dimensions to match the scaled image
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) view.getLayoutParams();
params.width = width;
params.height = height;
view.setLayoutParams(params);
Log.i("Test", "done");
}
private int dpToPx(int dp) {
float density = getApplicationContext().getResources().getDisplayMetrics().density;
return Math.round((float)dp * density);
}
The xml code for the ImageView:
<ImageView a:id="#+id/image_box"
a:background="#ff0000"
a:src="#drawable/star"
a:layout_width="wrap_content"
a:layout_height="wrap_content"
a:layout_marginTop="20dp"
a:layout_gravity="center_horizontal"/>
Thanks to this discussion for the scaling code:
http://www.anddev.org/resize_and_rotate_image_-_example-t621.html
UPDATE 7th, November 2012:
Added null pointer check as suggested in comments
<ImageView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="centerCrop"
android:adjustViewBounds="true"/>
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 currentBitmapWidth = bitMap.getWidth();
int currentBitmapHeight = bitMap.getHeight();
int ivWidth = imageView.getWidth();
int ivHeight = imageView.getHeight();
int newWidth = ivWidth;
newHeight = (int) Math.floor((double) currentBitmapHeight *( (double) new_width / (double) currentBitmapWidth));
Bitmap newbitMap = Bitmap.createScaledBitmap(bitMap, newWidth, newHeight, true);
imageView.setImageBitmap(newbitMap)
enjoy.
try adding android:scaleType="fitXY" to your ImageView.
The Best solution that works in most cases is
Here is an example:
<ImageView android:id="#+id/avatar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY"/>
this can all be done using XML... the other methods seem pretty complicated.
Anyway, you just set the height to what ever you want in dp, then set the width to wrap content or visa versa. Use scaleType fitCenter to adjust the size of the image.
<ImageView
android:layout_height="200dp"
android:layout_width="wrap_content"
android:scaleType="fitCenter"
android:adjustViewBounds="true"
android:src="#mipmap/ic_launcher"
android:layout_below="#+id/title"
android:layout_margin="5dip"
android:id="#+id/imageView1">
After searching for a day, I think this is the easiest solution:
imageView.getLayoutParams().width = 250;
imageView.getLayoutParams().height = 250;
imageView.setAdjustViewBounds(true);
Edited Jarno Argillanders answer:
How to fit Image with your Width and Height:
1) Initialize ImageView and set Image:
iv = (ImageView) findViewById(R.id.iv_image);
iv.setImageBitmap(image);
2) Now resize:
scaleImage(iv);
Edited scaleImage method: (you can replace EXPECTED bounding values)
private void scaleImage(ImageView view) {
Drawable drawing = view.getDrawable();
if (drawing == null) {
return;
}
Bitmap bitmap = ((BitmapDrawable) drawing).getBitmap();
int width = bitmap.getWidth();
int height = bitmap.getHeight();
int xBounding = ((View) view.getParent()).getWidth();//EXPECTED WIDTH
int yBounding = ((View) view.getParent()).getHeight();//EXPECTED HEIGHT
float xScale = ((float) xBounding) / width;
float yScale = ((float) yBounding) / height;
Matrix matrix = new Matrix();
matrix.postScale(xScale, yScale);
Bitmap scaledBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, true);
width = scaledBitmap.getWidth();
height = scaledBitmap.getHeight();
BitmapDrawable result = new BitmapDrawable(context.getResources(), scaledBitmap);
view.setImageDrawable(result);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) view.getLayoutParams();
params.width = width;
params.height = height;
view.setLayoutParams(params);
}
And .xml:
<ImageView
android:id="#+id/iv_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal" />
if it's not working for you then replace android:background with android:src
android:src will play the major trick
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitCenter"
android:src="#drawable/bg_hc" />
it's working fine like a charm
Use this code:
<ImageView android:id="#+id/avatar"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:scaleType="fitXY" />
This did it for my case.
<ImageView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:scaleType="centerCrop"
android:adjustViewBounds="true" />
I needed to have an ImageView and an Bitmap, so the Bitmap is scaled to ImageView size, and size of the ImageView is the same of the scaled Bitmap :).
I was looking through this post for how to do it, and finally did what I want, not the way described here though.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/acpt_frag_root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/imageBackground"
android:orientation="vertical">
<ImageView
android:id="#+id/acpt_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:adjustViewBounds="true"
android:layout_margin="#dimen/document_editor_image_margin"
android:background="#color/imageBackground"
android:elevation="#dimen/document_image_elevation" />
and then in onCreateView method
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_scanner_acpt, null);
progress = view.findViewById(R.id.progress);
imageView = view.findViewById(R.id.acpt_image);
imageView.setImageBitmap( bitmap );
imageView.getViewTreeObserver().addOnGlobalLayoutListener(()->
layoutImageView()
);
return view;
}
and then layoutImageView() code
private void layoutImageView(){
float[] matrixv = new float[ 9 ];
imageView.getImageMatrix().getValues(matrixv);
int w = (int) ( matrixv[Matrix.MSCALE_X] * bitmap.getWidth() );
int h = (int) ( matrixv[Matrix.MSCALE_Y] * bitmap.getHeight() );
imageView.setMaxHeight(h);
imageView.setMaxWidth(w);
}
And the result is that image fits inside perfectly, keeping aspect ratio,
and doesn't have extra leftover pixels from ImageView when the Bitmap is inside.
Result
It's important ImageView to have
wrap_content and adjustViewBounds to true,
then setMaxWidth and setMaxHeight will work, this is written in the source code of ImageView,
/*An optional argument to supply a maximum height for this view. Only valid if
* {#link #setAdjustViewBounds(boolean)} has been set to true. To set an image to be a
* maximum of 100 x 100 while preserving the original aspect ratio, do the following: 1) set
* adjustViewBounds to true 2) set maxWidth and maxHeight to 100 3) set the height and width
* layout params to WRAP_CONTENT. */
I needed to get this done in a constraint layout with Picasso, so I munged together some of the above answers and came up with this solution (I already know the aspect ratio of the image I'm loading, so that helps):
Called in my activity code somewhere after setContentView(...)
protected void setBoxshotBackgroundImage() {
ImageView backgroundImageView = (ImageView) findViewById(R.id.background_image_view);
if(backgroundImageView != null) {
DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int width = displayMetrics.widthPixels;
int height = (int) Math.round(width * ImageLoader.BOXART_HEIGHT_ASPECT_RATIO);
// we adjust the height of this element, as the width is already pinned to the parent in xml
backgroundImageView.getLayoutParams().height = height;
// implement your Picasso loading code here
} else {
// fallback if no element in layout...
}
}
In my XML
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout_editor_absoluteY="0dp"
tools:layout_editor_absoluteX="0dp">
<ImageView
android:id="#+id/background_image_view"
android:layout_width="0dp"

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
<!-- other elements of this layout here... -->
</android.support.constraint.ConstraintLayout>
Note the lack of a constraintBottom_toBottomOf attribute. ImageLoader is my own static class for image loading util methods and constants.
I am using a very simple solution. Here my code:
imageView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.getLayoutParams().height = imageView.getLayoutParams().width;
imageView.setMinimumHeight(imageView.getLayoutParams().width);
My pictures are added dynamically in a gridview. When you make these settings to the imageview, the picture can be automatically displayed in 1:1 ratio.
Use Simple math to resize the image . either you can resize ImageView or you can resize drawable image than set on ImageView . find the width and height of your bitmap which you want to set on ImageView and call the desired method. suppose your width 500 is greater than height than call method
//250 is the width you want after resize bitmap
Bitmat bmp = BitmapScaler.scaleToFitWidth(bitmap, 250) ;
ImageView image = (ImageView) findViewById(R.id.picture);
image.setImageBitmap(bmp);
You use this class for resize bitmap.
public class BitmapScaler{
// Scale and maintain aspect ratio given a desired width
// BitmapScaler.scaleToFitWidth(bitmap, 100);
public static Bitmap scaleToFitWidth(Bitmap b, int width)
{
float factor = width / (float) b.getWidth();
return Bitmap.createScaledBitmap(b, width, (int) (b.getHeight() * factor), true);
}
// Scale and maintain aspect ratio given a desired height
// BitmapScaler.scaleToFitHeight(bitmap, 100);
public static Bitmap scaleToFitHeight(Bitmap b, int height)
{
float factor = height / (float) b.getHeight();
return Bitmap.createScaledBitmap(b, (int) (b.getWidth() * factor), height, true);
}
}
xml code is
<ImageView
android:id="#+id/picture"
android:layout_width="250dp"
android:layout_height="250dp"
android:layout_gravity="center_horizontal"
android:layout_marginTop="20dp"
android:adjustViewBounds="true"
android:scaleType="fitcenter" />
Quick answer:
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:src="#drawable/yourImage"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
Just write it in xml
android:scaleType="centerCrop"
Worked for me
In my case, I found the answer buried in a comment on this question (credit to #vida).
android:scaleType="centerInside"
How about using android:scaleType="centerInside" instead of android:scaleType="centerCrop"? It would also not crop the image but ensure that both width and height are less than or equal the imageview's width and height :) Here's a good visual guide for scaletypes: Android ImageView ScaleType: A Visual Guide
I just use ImageView inside ConstraintLayout and set adjustviewbound in ImageView to true.
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:src="#drawable/myimg"
android:adjustViewBounds="true"
/>
</androidx.constraintlayout.widget.ConstraintLayout>
