android - ImageView with only one rounded corner

Question

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>

Answer 1

The Material Components library introduced the ShapeableImageView starting from 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>

With jetpack compose 1.0.x 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)),
)
