【英文标题】：Error inflating class com.google.android.youtube.player.YouTubePlayerView

【问题描述】：

我无法开始使用 android Youtube API。 我有一个ActionBarActivity 有一个v4.ViewPager，我想在里面放多个YouTubePlayerSupportFragment。 我得到了Error inflating class com.google.android.youtube.player.YouTubePlayerView，我的提示是继承链中的某些东西是错误的，但我不知道是什么。

到目前为止我的代码： XML：

<FrameLayout android:layout_
android:layout_ >

<com.google.android.youtube.player.YouTubePlayerView
    android:id="@+id/youtube_player"
    android:layout_
    android:layout_
    android:background="#fff"
    android:padding="5dp" /> </FrameLayout>

Java：

public class MyYoutubeFragment extends YouTubePlayerSupportFragment 

private static final String API_KEY = "";

private String videoId = "qNggvk8QtaY";

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) 
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.fragment_youtube, container, false);

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

    return view;


@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult result) 
    Toast.makeText(getActivity(), "Failured to Initialize!", Toast.LENGTH_LONG).show();


@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) 
    player.setPlayerStateChangeListener(playerStateChangeListener);
    player.setPlaybackEventListener(playbackEventListener);

    if (!wasRestored) 
        player.cueVideo(videoId);

【问题讨论】：

请填写完整的logcat跟踪

完成了，希望你能帮到我

我也有同样的问题

如果您找到解决方案，也许您可​​以发布它

【参考方案1】：

像这样改变你的班级。也不要忘记使用真正的 API_KEY，在你的代码中它只是一个空字符串

public class MyYoutubeFragment extends YouTubePlayerSupportFragment 
private static final String API_KEY = "";
private String videoId = "qNggvk8QtaY";

public static MyYoutubeFragment newInstance()

    MyYoutubeFragment playerYouTubeFrag = new MyYoutubeFragment();

    playerYouTubeFrag.initialize(API_KEY, this);
    return playerYouTubeFrag;


@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult result) 
    Toast.makeText(getActivity(), "Failured to Initialize!", Toast.LENGTH_LONG).show();  


@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) 
    player.setPlayerStateChangeListener(playerStateChangeListener);
    player.setPlaybackEventListener(playbackEventListener);

    if (!wasRestored) 
        player.cueVideo(videoId);
    

也加载如下

fragmentManager.beginTransaction()
            .add(R.id.video_view, MyYoutubeFragment.newInstance())
            .commit();

【讨论】：

我在哪里进行交易？

这取决于你想在哪里加载 youtube 片段。例如对于原始问题，它应该在页面更改事件监听器中。
