标签式活动中的 Youtube Player 导致此错误 [英] Youtube Player Inside Tabbed Activity Cause This Error

问题描述

我有标签式活动，我想在第三个标签上播放 YouTube 视频.

I have tabbed activity and I want to have youtube video on third tab.

这是我的 java :

here's my java :

public class FragmentTutorial extends YouTubePlayerFragment {

    YouTubePlayerView youTubePlayerView;
    YouTubePlayer.OnInitializedListener onInitializedListener;

    public FragmentTutorial() {
        // Required empty public constructor
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        youTubePlayerView = (YouTubePlayerView) youTubePlayerView.findViewById(R.id.tutorial_youtube_player);

        onInitializedListener = new YouTubePlayer.OnInitializedListener() {
            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
                youTubePlayer.loadVideo("3LiubyYpEUk");
            }

            @Override
            public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

            }
        };

        youTubePlayerView.initialize(PlayerConfig.API_KEY, onInitializedListener);

        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_tutorial, container, false);
    }

}

这是我的 XML :

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.FragmentTutorial">

    <com.google.android.youtube.player.YouTubePlayerView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/tutorial_youtube_player" />

</FrameLayout>

这是我的 MainActivity :

and here's my MainActivity :

class FragmentAdapter extends FragmentPagerAdapter {

        public FragmentAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            switch (position){
                case 0:
                    return new FragmentHome();
                case 1:
                    return new FragmentCatalog();
                case 2:
                    return new FragmentTutorial();
            }
            return null;
        }

        @Override
        public int getCount() {
            return 3;
        }


        @Override
        public CharSequence getPageTitle(int position) {
            switch (position){
                //
                //Your tab titles
                //
                case 0: return "Home";
                case 1: return "Catalog";
                case 2: return "Tutorial";
                default: return null;
            }
        }
    }

当我尝试运行此代码时，出现以下错误:

when I tried to run this code, I got this following error :

Error:(80, 28) error: incompatible types: FragmentTutorial cannot be converted to Fragment

我在这里错过了什么?谢谢...

what did I missed here? thank you...

推荐答案

可能是Fragment类错了，YouTubePlayerFragment extends android.app.Fragment, FragmentPagerAdapter 需要 android.support.v4.app.Fragment 并且无法转换

Probably it is caused by the wrong Fragment class, YouTubePlayerFragment extends android.app.Fragment, FragmentPagerAdapter requires android.support.v4.app.Fragment and this cannot be converted

尝试使用 android.support.v13.app.FragmentPagerAdapter 代替 android.support.v4.app.FragmentPagerAdapter(其他片段应该扩展 android.app.片段)

try to use android.support.v13.app.FragmentPagerAdapter instead android.support.v4.app.FragmentPagerAdapter (other fragments should extends android.app.Fragment)
