Is there any way to change the radius of specific corner of Material design CardView

With the version 1.1.0 of the Material Component you can customize the shape of your component using the shapeAppearanceOverlay attribute.
You can use it in the view or in the style.

<com.google.android.material.card.MaterialCardView
      .....
      app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.MaterialCardView.Cut">

and then define your favorite shape:

  <style name="ShapeAppearanceOverlay.MaterialCardView.Cut" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSizeTopRight">0dp</item>
    <item name="cornerSizeTopLeft">16dp</item>
    <item name="cornerSizeBottomRight">16dp</item>
    <item name="cornerSizeBottomLeft">16dp</item>
  </style>

With the code you can apply a custom ShapeAppearanceModel to the corner of the card using something like:

float radius = getResources().getDimension(R.dimen.my_corner_radius);
cardView.setShapeAppearanceModel(
  cardView.getShapeAppearanceModel()
      .toBuilder()
      .setAllCorners(CornerFamily.ROUNDED,radius)
      .setTopRightCornerSize(0)
      .build());

I have a solution but it requires v21 Lollipop and above. You can do it programmatically as follows:

In your activity class have public static int radius = 20; and in your Oncreate();

CardView card = findViewById(R.id.my_card);


if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
   makeCustomOutline(card);
}

then define the function as follows:

 @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private void makeCustomOutline(CardView card){

    card.setOutlineProvider(new ViewOutlineProvider() {
        @Override
        public void getOutline(View view, Outline outline) {

            outline.setRoundRect(0, 0, view.getWidth(),
                    (view.getHeight() + radius), (float)radius );
        }
    });
    card.setClipToOutline(true);

}

by using the setRoundRect() method you can control which corner of the cardview gets the radius and which doesn't. The above code will make only the top corners rounded, bottom corners will not be rounded.
