如何在Android中播放视频时禁用触摸屏事件

Question

我正在开发儿童应用程序，其中我已经在RecyclerView中显示了youtube视频缩略图。点击任何列出的视频缩略图，全屏播放视频（使用YouTube API获取缩略图并以Youtube意图播放视频）。我成功了，我这样做。问题是我想在视频播放时禁用触摸屏事件。各种帮助表示赞赏。下面是我的代码：
mainactivity.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:weightSum="2" 
    android:orientation="vertical" 
    tools:context="com.example.pc.fkidshell.Main4Activity"> 

    <include layout="@layout/toolbar" 
     android:id="@+id/my_thirdtoolbar"/> 

    <android.support.v7.widget.RecyclerView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:id="@+id/VideoList" 
     android:layout_below="@+id/my_thirdtoolbar" 
     android:paddingTop="20dp" 
     android:scrollbars="vertical"> 

    </android.support.v7.widget.RecyclerView> 
</RelativeLayout> 

video_row.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
    <ImageView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:id="@+id/thumbnailView" 
     android:layout_gravity="center_horizontal"/> 
</LinearLayout> 

mainactivity.java：

public class Main4Activity extends AppCompatActivity implements YouTubeThumbnailView.OnInitializedListener, YouTubeThumbnailLoader.OnThumbnailLoadedListener{ 
    Toolbar third_toolbar; 
    YouTubeThumbnailView thumbnailView; 
    YouTubeThumbnailLoader thumbnailLoader; 
    RecyclerView VideoList; 
    RecyclerView.Adapter adapter; 
    List<Drawable> thumbnailViews; 
    List<String> VideoId; 
    String videoid; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main4); 
     third_toolbar = (Toolbar) findViewById(R.id.my_thirdtoolbar); 
     setSupportActionBar(third_toolbar); 
     getSupportActionBar().setTitle(R.string.sectitle); 
     getSupportActionBar().setIcon(R.drawable.tblogo); 

     thumbnailViews = new ArrayList<>(); 
     VideoList = (RecyclerView) findViewById(R.id.VideoList); 
     RecyclerView.LayoutManager layoutManager=new LinearLayoutManager(this); 
     VideoList.setLayoutManager(layoutManager); 
     adapter=new VideoListAdapter(); 
     VideoList.setAdapter(adapter); 
     VideoId = new ArrayList<>(); 
     thumbnailView = new YouTubeThumbnailView(this); 
     thumbnailView.initialize("API Key", this); 

    } 

    @Override 
    public void onInitializationSuccess(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader youTubeThumbnailLoader) { 
     thumbnailLoader = youTubeThumbnailLoader; 
     youTubeThumbnailLoader.setOnThumbnailLoadedListener(Main4Activity.this); 
     thumbnailLoader.setPlaylist("PLXRActLQ03oY_6AQb-5EMuKFYQA_fDE40"); 
    } 

    @Override 
    public void onInitializationFailure(YouTubeThumbnailView youTubeThumbnailView, YouTubeInitializationResult youTubeInitializationResult) { 

    } 

    public void add() { 
     adapter.notifyDataSetChanged(); 
     if (thumbnailLoader.hasNext()) 
      thumbnailLoader.next(); 
    } 

    @Override 
    public void onThumbnailLoaded(YouTubeThumbnailView youTubeThumbnailView, String s) { 
     thumbnailViews.add(youTubeThumbnailView.getDrawable()); 
     VideoId.add(s); 
     add(); 
    } 

    @Override 
    public void onThumbnailError(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader.ErrorReason errorReason) { 

    } 

    public class VideoListAdapter extends RecyclerView.Adapter<VideoListAdapter.MyView>{ 
     public class MyView extends RecyclerView.ViewHolder{ 
      ImageView imageView; 
      public MyView(View itemView) { 
       super(itemView); 
       imageView= (ImageView) itemView.findViewById(R.id.thumbnailView); 
      } 
     } 

     @Override 
     public VideoListAdapter.MyView onCreateViewHolder(ViewGroup parent, int viewType) { 
      View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.video_row, parent, false); 
      return new MyView(itemView); 
     } 

     @Override 
     public void onBindViewHolder(VideoListAdapter.MyView holder, final int position) { 
      holder.imageView.setImageDrawable(thumbnailViews.get(position)); 
      holder.imageView.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) 
       { 
        videoid=VideoId.get(position); 

        Intent intent=new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.youtube.com/watch?v="+videoid+"&index="+position+"&list=PLXRActLQ03oY_6AQb-5EMuKFYQA_fDE40")); 
        intent.putExtra("force_fullscreen",true); 
        startActivity(intent); 

       } 
      }); 
     } 

     @Override 
     public int getItemCount() { 
      return thumbnailViews.size(); 
     } 
    } 
}

我的解决方案，你应该让YoutubePlayerActivity.java

public class YoutubePlayerActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener, 
     YouTubePlayer.PlaybackEventListener { 

    public static final String KEY_VIDEO_ID = "videoId"; 
    private static final int RECOVERY_REQUEST = 1; 
    private static final String API_KEY = "your API_KEY"; 

    private YouTubePlayerView youTubePlayerView; 
    private View topLayer; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_youtube_player); 

     youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtube_player); 
     youTubePlayerView.initialize(API_KEY, this); 

     topLayer = findViewById(R.id.top_layer); 

     WindowManager wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE); 
     DisplayMetrics dm = new DisplayMetrics(); 
     wm.getDefaultDisplay().getMetrics(dm); 

     topLayer.setLayoutParams(new RelativeLayout.LayoutParams(dm.widthPixels - 1, dm.heightPixels - 1)); 
     topLayer.setClickable(true); 
    } 

    @Override 
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean wasRestored) { 
     if (!wasRestored) { 
      youTubePlayer.setPlaybackEventListener(this); 
      youTubePlayer.loadVideo(getIntent().getStringExtra(KEY_VIDEO_ID)); 
     } 
    } 

    @Override 
    public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) { 
     if (youTubeInitializationResult.isUserRecoverableError()) { 
      youTubeInitializationResult.getErrorDialog(this, RECOVERY_REQUEST).show(); 
     } 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (requestCode == RECOVERY_REQUEST) { 
      // Retry initialization if user performed a recovery action 
      youTubePlayerView.initialize(API_KEY, this); 
     } 
    } 

    @Override 
    public void onPlaying() { 
     topLayer.setVisibility(View.VISIBLE); 
    } 

    @Override 
    public void onPaused() { 

    } 

    @Override 
    public void onStopped() { 
     topLayer.setVisibility(View.GONE); 
    } 

    @Override 
    public void onBuffering(boolean b) { 

    } 

    @Override 
    public void onSeekTo(int i) { 

    } 
} 

，打造布局，我把它命名为activity_youtube_player.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <com.google.android.youtube.player.YouTubePlayerView 
     android:id="@+id/youtube_player" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:fitsSystemWindows="false" /> 

    <View 
     android:id="@+id/top_layer" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_centerInParent="true" 
     android:clickable="true" /> 
</RelativeLayout> 

可以使用

Intent openYoutubePlayerActivity = new Intent(context, YoutubePlayerActivity.class); 
openYoutubePlayerActivity.putExtra(YoutubePlayerActivity.KEY_VIDEO_ID, videoId); 
startActivity(openYoutubePlayerActivity); 

于是开始YoutubePlayerActivity，代码做了什么？它会自动播放YouTube视频，并在视频开始时在YouTubePlayerView之上显示透明图层。透明图层上的android:clickable="true"属性将防止任何直接点击到YouTubePlayerView。视频停止后（由错误或视频结束），它将删除透明层。如果需要，您也可以直接在onStopped()方法内拨打finish();。
