使用环境：

         使用到surfaceView，发现底部总有部分不能填充

使用方法：

获取到surfaceView的实际宽高，将这个宽高通过surfaceView的holder赋值。

代码如下：

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        if (hasFocus) {
            int width = mSurfaceView.getMeasuredWidth() / 2;
            //int height = mSurfaceView.getMeasuredHeight();
            SurfaceHolder holder = mSurfaceView.getHolder();
            holder.setFixedSize(width, width);
            //setSurfaceViewCorner(width);
        }
    }

项目中需要用到圆形的surfaceView，代码如下：

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    private void setSurfaceViewCorner(final float radius) {
        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,
                        rect.bottom - rect.top);
                LogUtil.e("right-->" + (rect.right - rect.left));
                LogUtil.e("bottom-->" + (rect.bottom - rect.top));
                outline.setRoundRect(selfRect, radius);
            }
        });
        mSurfaceView.setClipToOutline(true);
    }
