我正在尝试在片段中初始化 youtubeplayer 片段。我成功地在一个活动中实现了片段，但是在片段中初始化它时遇到了问题。活动的代码片段如下
public class MainActivity extends AppCompatActivity {
private YouTubePlayerSupportFragmentX youTubePlayerFragment;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initializeYoutubePlayer();
private void initializeYoutubePlayer() {
youTubePlayerFragment = (YouTubePlayerSupportFragmentX) getSupportFragmentManager().findFragmentById(R.id.youtube_player_fragment);
if (youTubePlayerFragment == null)
return;
youTubePlayerFragment.initialize(Constants.DEVELOPER_KEY, new YouTubePlayer.OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
boolean wasRestored) {
if (!wasRestored) {
youTubePlayer = player;
//set the player style default
youTubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
//cue the 1st video by default
youTubePlayer.cueVideo(youtubeVideoArrayList.get(0));
youTubePlayer.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE);
}
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider arg0, YouTubeInitializationResult arg1) {
//print or show error if initialization failed
Log.e(TAG, "Youtube Player View initialization failed");
}
});
}
将此代码转换为片段，我尝试了这个
public class Welcome extends Fragment {
private YouTubePlayerSupportFragmentX youTubePlayerFragment;
private YouTubePlayer youTubePlayer;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_welcome, container, false);
initializeYoutubePlayer();
private void initializeYoutubePlayer() {
youTubePlayerFragment = (YouTubePlayerSupportFragmentX) getSupportFragmentManager().findFragmentById(R.id.youtube_player_fragment);
if (youTubePlayerFragment == null)
return;
youTubePlayerFragment.initialize(Constants.DEVELOPER_KEY, new YouTubePlayer.OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
if (!wasRestored) {
youTubePlayer = player;
//set the player style default
youTubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
//cue the 1st video by default
youTubePlayer.cueVideo(youtubeVideoArrayList.get(0));
youTubePlayer.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE);
}
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
Log.e(TAG, "Youtube Player View initialization failed");
}
});
}
private void getSupportFragmentManager() {
}
}
但在查找片段布局时出错。有人可以指导我如何在片段中做到这一点吗？Welcome片段的布局如下
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
