涉及主控: RK3566
Android: 11/13

问题

在使用GLSurfaceView播放视频的过程中, 增加了一个播放控制面板, 覆盖在视频上方. 默认隐藏setVisibility(View.INVISIBLE);点击屏幕再显示出来. 然而, 在RK3566上这个简单的功能却无法正常工作. 通过缩小视频窗口可以看到, 实际UI是已经展示, 但是被GLSurfaceView 覆盖了.

在Pixel Android 13 上不存在这个问题

如上图 红色 框选区域, 显示不出来.

分析

后续测试发现问题复现需要2个条件:

1. 覆盖层默认布局设置了隐藏: android:visibility="invisible"
2. 布局中使用了SurfaceView / GLSurfaceView

参考代码:

                mmp.setLooping(true);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    @Override
    protected void onStop() {
        super.onStop();
        if(mmp != null){
            mmp.stop();
            mmp.release();
        }
    }
}

解决

在需要展示覆盖层的时候调用一次requestLayout, 比如:

    void showOrHideMenu(){
        Log.d(TAG, "showOrHideMenu");
        rlMenu.setVisibility(rlMenu.getVisibility() == View.VISIBLE ? View.INVISIBLE : View.VISIBLE);
        //
        //((RelativeLayout)findViewById(R.id.rlRoot)).requestLayout();
        rlMenu.requestLayout();
    }

调用父容器 rlRoot 或 rlMenu本身 的requestLayout 都可以
