Android – ImageView with rounded only one corner

You can use the Material Components Library.
With the version 1.2.0-alpha03 there is the new ShapeableImageView.

Just use in your layout:

  <com.google.android.material.imageview.ShapeableImageView
      app:srcCompat="@drawable/..."
      ../>

And in your code apply the ShapeAppearanceModel with:

float radius = getResources().getDimension(R.dimen.default_corner_radius);
imageView.setShapeAppearanceModel(imageView.getShapeAppearanceModel()
    .toBuilder()
    .setTopRightCorner(CornerFamily.ROUNDED,radius)
    .setBottomLeftCorner(CornerFamily.ROUNDED,radius)
    .build());

enter image description here

You can use this library and put your ImageView inside the Layout

and can set the radius for specific corners like this

containerLayout.setCornerRadius(2f, CornerType.ALL);
containerLayout.setCornerRadius(2f, CornerType.BOTTOM_LEFT);

public final enum class CornerType private constructor() : kotlin.Enum<com.jcminarro.roundkornerlayout.CornerType> {
    ALL,

    TOP_LEFT,

    TOP_RIGHT,

    BOTTOM_RIGHT,
