How to make an ImageView with rounded corners?

Question

In Android, an ImageView is a rectangle by default. How can I make it a rounded rectangle (clip off all 4 corners of my Bitmap to be rounded rectangles) in the ImageView?

Answer 1

I have done by Custom ImageView:

public class RoundRectCornerImageView extends ImageView {

    private float radius = 18.0f;
    private Path path;
    private RectF rect;

    public RoundRectCornerImageView(Context context) {
        super(context);
        init();
    }

    public RoundRectCornerImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public RoundRectCornerImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    private void init() {
        path = new Path();

    }

    @Override
    protected void onDraw(Canvas canvas) {
        rect = new RectF(0, 0, this.getWidth(), this.getHeight());
        path.addRoundRect(rect, radius, radius, Path.Direction.CW);
        canvas.clipPath(path);
        super.onDraw(canvas);
    }
}
