我一直在尋找這個問題的答案（這個錯誤有很多問題），但沒有一個適合我。所以我想調用兩個片段。如果我只打電話給YouTube片段，一切正常。在其他活動（只有AdsFragment）一切正常工作也。android.view.InflateException：二進制XML文件行＃17：錯誤膨脹類片段
這裏是：
studio.java
public class Studio extends YouTubeFailureRecoveryActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_studio);
YouTubePlayerFragment youTubePlayerFragment =
(YouTubePlayerFragment) getFragmentManager().findFragmentById(R.id.youtube_fragment);
youTubePlayerFragment.initialize("myapikey", this);
}
@Override
public void onStart() {
super.onStart();
EasyTracker.getInstance(this).activityStart(this); // Add this method.
}
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
boolean wasRestored) {
if (!wasRestored) {
player.cueVideo("film");
}
}
@Override
protected YouTubePlayer.Provider getYouTubePlayerProvider() {
return (YouTubePlayerFragment) getFragmentManager().findFragmentById(R.id.youtube_fragment);
}
public void showPlaylist(View view){
Intent intent = YouTubeIntents.createUserIntent(this, "User");
startActivity(intent);
}
@Override
public void onStop() {
super.onStop();
// The rest of your onStop() code.
EasyTracker.getInstance(this).activityStop(this); // Add this method.
}
}
這裏是activity_studio.xml

它很奇怪，因爲它工作的其他活動非常正常......我將AdsFragment.java添加到我的問題 – wzieba
@tuksiarz：請檢查您的'Fragment'的import語句，看看您的'Fragment'實現進口。 – CommonsWare
我已經導入了這個'import android.support.v4.app.Fragment' – wzieba
