Question

我正在开发Android应用，就像使用youtube在视图寻呼机中播放多个视频一样。我无法播放所有视频。只有第一个和丢失的位置视频正在播放，其他视频显示为空白屏幕。

这是我的主要代码 -

    public class MainActivity extends FragmentActivity {

    // Widgets
      private VerticalViewPager viewPager;
      private PagerAdapter adapter;

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

  find_view_by_id();
  fetchVideo();
  }

 private void find_view_by_id() {

  viewPager = (VerticalViewPager) findViewById(R.id.pager);

  }

  private void fetchVideo() {
  .
  .
  ..adapter = new PagerAdapter(getSupportFragmentManager(),video_detail);
            viewPager.setAdapter(adapter);
 }

我的适配器类 - ＆gt;

    public class ViewPagerAdapter extends PagerAdapter implements YouTubePlayer.OnInitializedListener {

// Widgets
private YouTubePlayerView youTubeView;
private TextView txttitle, txtexplanation;

// Variables
public static final String API_KEY = "xxx";
public static String VIDEO_ID = "";

private ArrayList<String> mTitle;
private ArrayList<String> mExplanation;
private ArrayList<String> mArrayvid;


// Others
Context mContext;
LayoutInflater inflater;

public ViewPagerAdapter( Context context, ArrayList<String> title, ArrayList<String> explanation, ArrayList<String> arrayvid) {

    this.mContext = context;
    this.mTitle = title;  // title
    this.mExplanation = explanation;  // description
    this.mArrayvid = arrayvid;  //video link

}

@Override
public int getCount() {
    return mArrayvid.size();
}

@Override
public boolean isViewFromObject(View view, Object object) {
    return view == ((LinearLayout) object);
}

@Override
public Object instantiateItem(ViewGroup container, final int position) {

    inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View itemView = inflater.inflate(R.layout.viewpager_item, container, false);

    txttitle = (TextView) itemView.findViewById(R.id.txt_title);
    txtexplanation = (TextView) itemView.findViewById(R.id.txt_desc);
    youTubeView = (YouTubePlayerView) itemView.findViewById(R.id.youtube_player);

    txttitle.setText(mTitle.get(position));
    txtexplanation.setText(mExplanation.get(position));

    String[] videoId = mArrayvid.get(position).split("/");
    VIDEO_ID = videoId[videoId.length - 1];
    Log.e("videoid", mArrayvid.get(position));

    youTubeView.initialize(VIDEO_ID, this);


    (container).addView(itemView);
    return itemView;
}

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean wasRestored) {
    if (youTubePlayer != null) {
        youTubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
        youTubePlayer.loadVideo(VIDEO_ID);
        youTubePlayer.play();
        if (!wasRestored) {
            youTubePlayer.cueVideo(VIDEO_ID);
        }
    }
}

@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
    Toast.makeText(mContext, "Failed to initialize.", Toast.LENGTH_LONG).show();
    Log.e("Init Error: ", youTubeInitializationResult.toString());
}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    ((ViewPager) container).removeView((LinearLayout) object);
}

}

我的xml布局 - - ＆gt;

     <com.google.android.youtube.player.YouTubePlayerView
    android:id="@+id/youtube_player"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />

和主要xml布局 - ＆gt;＆gt;

      <view
    android:id="@+id/pager"
    class="com.example.inbridge08.videoswap.VerticalViewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="8.6" />

并且plz建议像这样的 lib或github项目。谢谢

使用android中的pageradapter无法在viewpager中播放多个视频
