我正试图在片段中播放视频。但是,我无法让它发挥作用。如果我正在扩展'YoutubeFailureRecovery',我会得到:
09-06 21:56:40.472:E / AndroidRuntime(4946):引起:java.lang.IllegalStateException:只能使用扩展YouTubeBaseActivity作为其上下文的Activity创建YouTubePlayerView。
这是我的.xml:
<com.google.android.youtube.player.YouTubePlayerView
android:id="@+id/player"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
这是班级:
public class YoutubeFragment extends YoutubeFailureRecovery {
YouTubePlayer player;
YouTubePlayerView playerView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle arg2) {
// TODO Auto-generated method stub
return inflater.inflate(R.layout.detailview, container, false);
}
@Override
public void onStart() {
// TODO Auto-generated method stub
super.onStart();
playerView = (YouTubePlayerView)getActivity().findViewById(R.id.player);
playerView.initialize(DataHolder.DEVELOPER_KEY, this);
}
@Override
public void onInitializationSuccess(Provider provider, YouTubePlayer player,
boolean wasRestored) {
// TODO Auto-generated method stub
player.cueVideo("nCgQDjiotG0");
}
@Override
protected Provider getYouTubePlayerProvider() {
// TODO Auto-generated method stub
return playerView;
}
}
public abstract class YoutubeFailureRecovery extends YouTubePlayerSupportFragment implements YouTubePlayer.OnInitializedListener{
我只是不知道该怎么做。我尝试使用'YoutubePlayerSupportFragment'扩展我的Fragment类,尝试在XML中添加类似视频的片段,但没有任何工作(错误膨胀)。也许有人在Fragment中使用YouTube API有一些经验?

YouTubePlayerView仅适用于扩展的活动 YouTubeBaseActivity。
如果您想使用片段,您必须使用YoutubePlayerFragment / SupportFragment。
例如,您可以创建从YoutubePlayerSupportFragment继承的自定义片段:
public class VideoFragment extends YouTubePlayerSupportFragment {
public VideoFragment() { }
public static VideoFragment newInstance(String url) {
VideoFragment f = new VideoFragment();
Bundle b = new Bundle();
b.putString("url", url);
f.setArguments(b);
f.init();
return f;
}
private void init() {
initialize("yourapikey", new OnInitializedListener() {
@Override
public void onInitializationFailure(Provider arg0, YouTubeInitializationResult arg1) { }
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
if (!wasRestored) {
player.cueVideo(getArguments().getString("url"));
}
}
});
}
}
在代码中它看起来像这样:
VideoFragment f = VideoFragment.newInstance("your-video-url");
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, f).commit();
&#34; fragment_container &#34;在这种情况下应该是一个空 FrameLayout 。
