Say, your play icon is transparent, then use overlay technique to draw this play icon on your imageview image. Just use the following function:

 public Bitmap putOverlay(Bitmap bmp1, Bitmap overlay) {
        Bitmap bmOverlay = Bitmap.createBitmap(bmp1.getWidth(), bmp1.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bmOverlay);
        Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG);

            canvas.drawBitmap(bmp1, 0, 0, null); 
            canvas.drawBitmap(overlay, 0, 0, null);       

        return bmOverlay;
    }

Pass image of your corresponding imageview and another image(for ex: play icon), it returns a merged image which you can set to your imageview. You can also extend ImageView class and override onDraw method to accomplish it.
