I think witch canvas this is posible but i am not sure.

Anyone have a example of this?

Answer 1

You can use FrameLayout , make big image to be the background and the little one to be on the foreground. You can change its gravity using the android:layout_gravity attribute. FrameLayout documentation here . Hope this helps.

Answer 2

You could make the first image the content of a class that extends from ImageView. Then in this class, override onDraw(Canvas canvas), drawing the second the image as a Bitmap at the coordinates you specify.

Eg

public class DoubleImage extends ImageView
{
    private Bitmap mSecondBitmap;
    public DoubleImage(Context context, AttributeSet attrs)
    {
         super(context, attrs);

         // load the second image into mSecondBitmap
         mSecondBitmap = BitmapFactory.decodeResource(context, R.drawable.my_second_image);
    }

    @Override
    protected void onDraw(Canvas canvas)
    {
        super.onDraw(canvas);

        canvas.drawBitmap(mSecondImage, x, y, null);
    }
}
