错误膨胀类 com.google.android.youtube.player.YouTubePlayerView

问题描述 投票：0回答：2

我在开始使用 Android Youtube API 时遇到了麻烦。
我有一个

ActionBarActivity
，它有一个
v4.ViewPager
，我想在里面放多个
YouTubePlayerSupportFragment
。
我得到
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_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="wrap_content"
    android:background="#fff"
    android:padding="5dp" /> </FrameLayout>

爪哇：

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);
    }
}

}

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();

要解决此问题，您可以按照以下步骤操作：

更新您的 Activity 类以扩展 YouTubeBaseActivity 而不是标准 Activity 类。例如：

java

public class PlayerActivity extends YouTubeBaseActivity {
    // Your activity code here
}

或在 Kotlin 中：

class PlayerActivity : YouTubeBaseActivity() {
    // Your activity code here
}

注意：如果您在项目中使用不同的基础活动类（例如，来自 AndroidX 库的 AppCompatActivity），您应该使用 YouTubeBaseSupportFragment 而不是 YouTubeBaseActivity。
