onStart（）中添加：
//设置沉浸式状态栏
getWindow().addFlags(WindowManager.LayoutConfig.MARK_TRANSLUCENT_STATUS);
initPlayer();
需要重写两个回调：VideoSurfaceCallback 、VideoPlayerCallback
private void initPlayer() {
    sfProvider=(SurfaceProvider) findComponentById(ResourceTable.Id_surfaceProvider);
    image=(Image) findComponentById(ResourceTable.Id_img);
    sfProvider.getSurfaceOps().get().addCallback(new VideoSurfaceCallback());
    //sfProvider.pinToZTop(boolean)--如果设置为true, 视频控件会在最上次展示，但是设置为false时，虽然不在最上层展示，却出现黑屏，
    // 需加上一行代码：WindowManager.getInstance().getTopWindow().get().setTransparent(true);
    sfProvider.pinToZTop(false);
    WindowManager.getInstance().getTopWindow().get().setTransparent(true);
    player=new Player(getContext());
//sfProvider添加监听事件
    sfProvider.setClickedListener(new Component.ClickedListener() {
        @Override
        public void onClick(Component component) {
            if(player.isNowPlaying()){
                //如果正在播放，就暂停
                player.pause();
                //播放按钮可见
                image.setVisibility(Component.VISIBLE);
            }else {
                //如果暂停，点击继续播放
                player.play();
                //播放按钮隐藏
                image.setVisibility(Component.HIDE);
