Android - MaterialCardView corner radius not showing up in fragments

I created a cornerRadius card view and my codes work well in activity but the problem now is that the cardview does not show the rounded edges and elevation in fragment but it shows in the design codes and in activity. my codes are shown blow:
raounded_corners.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

</com.google.android.material.card.MaterialCardView>
</RelativeLayout>
In Fragment
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.raounded_corners,container,false);
return v;
}
raounded_corners.xml layout cornerRadius showing in activity but not showing in fragment
How to fix this.
In Activity
in fragment

If you are trying to make the imageview circular, I propose this approach.Create the custom view and set it in your xml. It works perfectly. If this helps you, an upvote will be appreciated.
Create a custom Circular view like shown below. CircleImageView.java

Set the view in your xml
<com.fishpott.fishpott5.Views.CircleImageView
android:id="#+id/activity_setprofilepicture_profilepicture_imageview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/none"
android:src="#drawable/setprofilepicture_activity_imageholder_default_image"
app:civ_border_color="#android:color/transparent"
app:civ_border_width="0dp" />
The reason you see "Views" in my xml call of the CircleImageView is because my CircleImageView.java is in "Views" folder/package.

ImageView with only one rounded corner

I'm trying to make one rounded corner of ImageView like in the picture below but with bottom right corner. Tried using background shape but it's not working at all. All images loaded by Glide. Should i use something like ViewOutlineProvider? Is there are an efficient way to do this? Thanks!
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<corners
android:radius="2dp"
android:bottomRightRadius="20dp"
android:bottomLeftRadius="0dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp"/>
</shape>

With jetpack compose you can apply the clip Modifier using a RoundedCornerShape:
Image(painterResource(id = R.drawable.xxx),
contentDescription = "xxxx",
contentScale = ContentScale.Crop,
modifier = Modifier
.size(xx.dp,xx.dp)
.clip(RoundedCornerShape(topStart = 12.dp)),
)
With The Material Components library you can use the ShapeableImageView (introduced with the version 1.2.0-alpha03).
Just use something like:
<com.google.android.material.imageview.ShapeableImageView
android:id="#+id/image_view"
android:scaleType="centerInside"
android:adjustViewBounds="true"
../>
then in your code you can apply the ShapeAppearanceModel with:
ShapeableImageView imageView = findViewById(R.id.image_view);
float radius = getResources().getDimension(R.dimen.default_corner_radius);
imageView.setShapeAppearanceModel(imageView.getShapeAppearanceModel()
.toBuilder()
.setTopRightCorner(CornerFamily.ROUNDED,radius)
.build());
You can also apply in the xml the shapeAppearanceOverlay parameter:
<com.google.android.material.imageview.ShapeableImageView
app:shapeAppearanceOverlay="#style/customRroundedImageView"
app:srcCompat="#drawable/ic_image" />
with:
<style name="customRoundedImageView" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">0dp</item>
<item name="cornerSizeTopRight">8dp</item>
</style>

Also if you want to get rid of writing code in ".java" file. Then you can define style like below and just add it to your ShapeableImageView:
<com.google.android.material.imageview.ShapeableImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ex_image"
app:shapeAppearanceOverlay="#style/roundedImageView"
/>
then:
<style name="roundedImageView" parent="">
<item name="cornerFamilyTopRight">rounded</item>
<item name="cornerSizeTopRight">30dp</item>
</style>

this is your main layout file which uses a custom drawable "round_one.xml"file. just copy and paste this code.
it will hopefully meet your requirements.

Creating RoundImageView causes NullPointerException

I want to create RoundedImageView for some ImageView used in my app. I am creating custom view for that.
Below is the Xml file and source code for custom ImageView.

Circular imageview with downloading from url

I am downloading image from url with ion library.It is working like this:
holder.imageView=(ImageView)convertView.findViewById(R.id.image);
Ion.with(holder.imageView).load(image_url);
My imageView xml:
<ImageView
android:id="#+id/image"
android:layout_width="64dp"
android:layout_height="64dp"
android:src="#drawable/defaultprofile"/>
I want to use this imageview as circular imageview.
I have found that question:How to Make an ImageView in Circular Shape?
But in that question they are using static image.I mean they don't download from url.How can I use circular image with downloading from url or what is the best library for me ?

Use Picasso. It is the best (for me) image downloading library which also handles caching. https://github.com/square/picasso You can also set a placeholder while the image is loading and you can do so much more than that.
For the circular ImageView you can use this library: https://github.com/hdodenhof/CircleImageView or one of the others Butani Vijay gave, but you can also use transformation specifically for Picasso: https://gist.github.com/julianshen/5829333
I'm using Picasso with this transformation method in my own apps.

You can use any one of below :
https://github.com/hdodenhof/CircleImageView
https://github.com/Pkmmte/CircularImageView
https://github.com/lopspower/CircularImageView
You need to create custome ImageView
Example :
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Shader;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;
public class CircularImageView extends ImageView {

this(context, null);
}
public CircularImageView(Context context, AttributeSet attrs) {
this(context, attrs, R.attr.circularImageViewStyle);
}
public CircularImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// init paint
paint = new Paint();
paint.setAntiAlias(true);
paintBorder = new Paint();
paintBorder.setAntiAlias(true);
// load the styled attributes and set their properties
TypedArray attributes = context.obtainStyledAttributes(attrs, R.styleable.CircularImageView, defStyle, 0);
if(attributes.getBoolean(R.styleable.CircularImageView_border, true)) {
int defaultBorderSize = (int) (4 * getContext().getResources().getDisplayMetrics().density + 0.5f);
setBorderWidth(attributes.getDimensionPixelOffset(R.styleable.CircularImageView_border_width, defaultBorderSize));
setBorderColor(attributes.getColor(R.styleable.CircularImageView_border_color, Color.WHITE));
}
if(attributes.getBoolean(R.styleable.CircularImageView_shadow, false))
addShadow();
}
public void setBorderWidth(int borderWidth) {
this.borderWidth = borderWidth;
this.requestLayout();
this.invalidate();
}
public void setBorderColor(int borderColor) {
if (paintBorder != null)
paintBorder.setColor(borderColor);
this.invalidate();
}
public void addShadow() {
setLayerType(LAYER_TYPE_SOFTWARE, paintBorder);
paintBorder.setShadowLayer(4.0f, 0.0f, 2.0f, Color.BLACK);
}
#Override
public void onDraw(Canvas canvas) {
// load the bitmap
image = drawableToBitmap(getDrawable());
// init shader
if (image != null) {
canvasSize = canvas.getWidth();
if(canvas.getHeight()<canvasSize)
canvasSize = canvas.getHeight();
BitmapShader shader = new BitmapShader(Bitmap.createScaledBitmap(image, canvasSize, canvasSize, false), Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
paint.setShader(shader);
// circleCenter is the x or y of the view's center
// radius is the radius in pixels of the cirle to be drawn
// paint contains the shader that will texture the shape
int circleCenter = (canvasSize - (borderWidth * 2)) / 2;
canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, ((canvasSize - (borderWidth * 2)) / 2) + borderWidth - 4.0f, paintBorder);
canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, ((canvasSize - (borderWidth * 2)) / 2) - 4.0f, paint);
}
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int width = measureWidth(widthMeasureSpec);
int height = measureHeight(heightMeasureSpec);
setMeasuredDimension(width, height);
}
private int measureWidth(int measureSpec) {
int result = 0;
int specMode = MeasureSpec.getMode(measureSpec);
int specSize = MeasureSpec.getSize(measureSpec);
if (specMode == MeasureSpec.EXACTLY) {
// The parent has determined an exact size for the child.
result = specSize;
} else if (specMode == MeasureSpec.AT_MOST) {

result = specSize;
} else {

return result;
}

result = specSize;
} else {
// Measure the text (beware: ascent is a negative number)
result = canvasSize;
}
return (result + 2);
}
public Bitmap drawableToBitmap(Drawable drawable) {
if (drawable == null) {
return null;
} else if (drawable instanceof BitmapDrawable) {
return ((BitmapDrawable) drawable).getBitmap();
}
Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(),
drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
drawable.draw(canvas);
return bitmap;
}
}
And use as below in your layout :
<com.yourpkg.CircularImageView
android:layout_width="64dp"
android:layout_height="64dp"
android:src="#drawable/image"
app:border="true"
app:border_color="#color/GrayLight"
app:border_width="4dp"
app:shadow="true" />

how can i show a square image in a circle?

I'm trying to mimic something from the iPhone version of my app. I have a square image and I want to show it in a circle with a white border around it. like this
Is there a way I can do this?

You can achieve this effect, or something very close to it, using a custom Drawable class, containing a Paint object with a BitmapShader that renders the image as a texture. This is the code I'm using (slightly adapted from Romain's Guy post, which uses the same technique to draw images with rounded corners).
class CircularDrawable extends Drawable
{
private float mCircleRadius;
private final RectF mBackgroundRect = new RectF();
private final Paint mBackgroundPaint;
private final BitmapShader mBitmapShader;
private final Paint mPaint;
private final int mMargin;
CircularDrawable(Bitmap bitmap, int margin, int backgroundColor)
{
mBitmapShader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
mPaint = new Paint();
mPaint.setAntiAlias(true);
mPaint.setShader(mBitmapShader);
mMargin = margin;
mBackgroundPaint = new Paint();
mBackgroundPaint.setColor(backgroundColor);
}
#Override
protected void onBoundsChange(Rect bounds)
{
super.onBoundsChange(bounds);
mBackgroundRect.set(bounds);
mCircleRadius = Math.min(bounds.width() / 2 - mMargin, bounds.height() / 2 - mMargin);
}
#Override
public void draw(Canvas canvas)
{
canvas.drawRect(mBackgroundRect, mBackgroundPaint);
canvas.drawCircle(mBackgroundRect.width() / 2, mBackgroundRect.height() / 2, mCircleRadius, mPaint);
}
#Override
public int getOpacity()
{
return PixelFormat.TRANSLUCENT;
}
#Override
public void setAlpha(int alpha)
{
mPaint.setAlpha(alpha);
mBackgroundPaint.setAlpha(alpha);
}
#Override
public void setColorFilter(ColorFilter cf)
{
mPaint.setColorFilter(cf);
mBackgroundPaint.setColorFilter(cf);
}
}
Having the bitmap you want to draw, just build a CircularDrawable from it with
new CircularDrawable(bitmap, margin, Color.WHITE);

Try this.
public class CircularImageView extends ImageView {
private int borderWidth;
private int viewWidth;
private int viewHeight;
private Bitmap image;
private Paint paint;
private Paint paintBorder;
private BitmapShader shader;
public CircularImageView(final Context context) {
this(context, null);
}
public CircularImageView(Context context, AttributeSet attrs) {
this(context, attrs, R.attr.circularImageViewStyle);
}
public CircularImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// init paint
paint = new Paint();
paint.setAntiAlias(true);
paintBorder = new Paint();
paintBorder.setAntiAlias(true);
// load the styled attributes and set their properties
TypedArray attributes = context.obtainStyledAttributes(attrs,
R.styleable.CircularImageView, defStyle, 0);
if (attributes.getBoolean(R.styleable.CircularImageView_border, true)) {
setBorderWidth(attributes.getColor(
R.styleable.CircularImageView_border_width, 4));
setBorderColor(attributes.getInt(
R.styleable.CircularImageView_border_color, Color.WHITE));
}
if (attributes.getBoolean(R.styleable.CircularImageView_shadow, false))
addShadow();
}
public void setBorderWidth(int borderWidth) {
this.borderWidth = borderWidth;
this.invalidate();
}
public void setBorderColor(int borderColor) {
if (paintBorder != null)
paintBorder.setColor(borderColor);
this.invalidate();
}
public void addShadow() {
setLayerType(LAYER_TYPE_SOFTWARE, paintBorder);
paintBorder.setShadowLayer(4.0f, 0.0f, 2.0f, Color.BLACK);
}

#Override

if (image != null) {
shader = new BitmapShader(Bitmap.createScaledBitmap(image,

int circleCenter = viewWidth / 2;
// circleCenter is the x or y of the view's center
// radius is the radius in pixels of the cirle to be drawn

if (specMode == MeasureSpec.EXACTLY) {
// We were told how big to be

return result;

I'd make a custom view and just draw what you want to the canvas- draw the border, then the white circle, then the image.It's a couple of easy canvas calls. If you need to clip the image to a circular area, just set a clipping Region before doing the image draw.
