       mSurfaceView.setOutlineProvider(new ViewOutlineProvider() {
            @Override
            public void getOutline(View view, Outline outline) {
                Rect rect = new Rect();
                view.getGlobalVisibleRect(rect);
                int leftMargin = 0;
                int topMargin = 0;
                Rect selfRect = new Rect(leftMargin, topMargin,
                        rect.right - rect.left - leftMargin,
                        rect.bottom - rect.top - topMargin);
                outline.setRoundRect(selfRect, 22);
            }
        });
        mSurfaceView.setClipToOutline(true);
