        <RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" >

            <ImageView

        </LinearLayout>

    </LinearLayout>

</RelativeLayout>

yet I still haven´t the solution

回答1:

this can only be done with a custom view. I had the same problem. Look for Custom ImageView and Paths and clipping Bitmaps. I wrote this snippet to clip a speech bubble shape out of a given bitmap:

  public static Bitmap clipit(Bitmap bitmapimg,int direct) {

    //1 = direction right
    //0 = direction left

      Bitmap output = Bitmap.createBitmap(bitmapimg.getWidth(),
                bitmapimg.getHeight(), Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final int color = 0xff424242;
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, bitmapimg.getWidth(),
                bitmapimg.getHeight());

        paint.setAntiAlias(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(color);

        if(direct == 0) {
        canvas.drawRect(0, 0, bitmapimg.getWidth()-15, bitmapimg.getHeight(), paint);
        Path path = new Path();
        path.moveTo(bitmapimg.getWidth()-15, 10);
        path.lineTo(bitmapimg.getWidth(), 20);
        path.lineTo(bitmapimg.getWidth()-15, 30);
        path.lineTo(bitmapimg.getWidth()-15, 10);
        canvas.drawPath(path,paint);
        }
        if(direct == 1) {
            canvas.drawRect(15, 0, bitmapimg.getWidth(), bitmapimg.getHeight(), paint);             
            Path path = new Path();
            path.moveTo(15, 10);
            path.lineTo(0, 20);
            path.lineTo(15, 30);
            path.lineTo(15, 10);
            canvas.drawPath(path,paint);    
        }


        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(bitmapimg, rect, rect, paint);
        return output;

  }

does this solve your problem?
