Question

我有一个recyclerview，onClick会显示一个带有全屏按钮的videoview。

但是，当我单击videoview上的全屏按钮时。我的RecyclerView再次显示（或创建）。

我只想以全屏模式在videoview中显示视频。

以下是我的Acticity OnCreate（）方法：

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mangal_stuti_activity);
toolbar = findViewById(R.id.toolbar);
toolbar.setBackgroundColor(getResources().getColor(R.color.colorPrimary));
setSupportActionBar(toolbar);
recyclerView = (findViewById(R.id.recycler_view));
mAdapter = new Adapter(this, movieList, this);

RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.addItemDecoration(new MyDividerItemDecoration(this, LinearLayoutManager.VERTICAL,16));
recyclerView.setAdapter(mAdapter);
recyclerView.setBackgroundColor(getResources().getColor(R.color.recyclerViewBackground));
recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getApplicationContext(), this.recyclerView, new RecyclerTouchListener.ClickListener()
{
  public void onClick(View view, int position) {
    toolbar.setVisibility(View.GONE);
      playVideo();

  }

  public void onLongClick(View paramAnonymousView, int paramAnonymousInt) {}
}));

prepareMovieData();  // possibly this function is creating the recyclerview again when the fullScreen is called..

mVideoView = findViewById(R.id.videoView);
mYouTuDraggingView = findViewById(R.id.youtube_view);
mYouTuDraggingView.setCallback(this);

controlPanel = new YoutubeControlPanel(this);
controlPanel.setYouTuDraggingView(mYouTuDraggingView);
mVideoView.setControlPanel(controlPanel);
controlPanel.getFullScreenIv().setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
    mYouTuDraggingView.fullScreenChange();
  }
});
controlPanel.getDownIv().setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {
    toolbar.setVisibility(View.VISIBLE);
    mYouTuDraggingView.fullScreenGoMin();
  }
});
}

YouTuDraggingView类中的fullScreenChange（）如下：

void fullScreenChange() {
    if (isLandscape()) {
        isLandscapeToPortrait = true;
        mActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);
    } else {
        isPortraitToLandscape = true;
        mActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
    }
}

mangal_stuti_activity.xml

当我单击视频视图上的全屏按钮时..仅将视频视图显示在全屏上..而不是recyclerview ...

我认为问题可能出在 mAdapter = new Adapter(this, movieList, this); movieList进入全屏模式时，会在其中创建另一个videoview。

任何对此的帮助将对我有很大帮助。预先感谢。.

Answer 1

请分享mangal_stuti_activity.xml代码。

确保将youtube_view的宽度和高度设置为match_parent。

Answer 2

使视频全屏显示时，您似乎要求更改方向。当活动方向改变时，活动将被销毁并重新创建。这是Activity Life Cycle的一部分。发生这种情况时，您需要对活动和RecyclerView做save and restore your state。

这是一个有关如何执行此操作的示例：

Answer 3

我刚刚将此行添加到了在AndroidManifest.xml文件中播放视频的活动中

android:configChanges="orientation|screenSize"

这阻止了重新创建活动。

当全屏视频观看时，将重新创建RecyclerView
