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，其中我在 RecyclerView 中显示了 youtube 视频缩略图。在点击任何列出的视频缩略图时，视频将全屏播放（使用 YouTube API 获取缩略图并在 Youtube 意图中播放视频）。我成功了，我这样做了。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。以下是我的代码：
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) {

    }
}

并创建布局，我将其命名为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>

您可以使用YoutubePlayerActivity 启动

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

那么，代码的作用是什么？它将自动播放 youtube 视频，并在视频开始时在 YouTubePlayerView 顶部显示透明层。透明层上的android:clickable="true" 属性将阻止任何直接点击YouTubePlayerView。视频停止后（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() 方法中调用 finish();。
