It can work

 public static Bitmap getBitmapFromView(View view) { Bitmap returnedBitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(),Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(returnedBitmap); view.layout(0, 0, view.getLayoutParams().width, view.getLayoutParams().height); view.draw(canvas); return returnedBitmap; }
