Question

My Activity扩展了另一个活动，包含导航抽屉，每个项目都打开一个新片段。我想将Youtube集成到其中一个片段中。以前我使用YouTubePlayerView将Youtube集成到活动中，但这里需要片段。我在网上搜索，发现YouTubePlayerFragment将youtube整合到片段中。但是当我在教程中搜索时，我发现即使使用YouTubePlayerFragment，我们也在扩展YouTubeBaseActivity。这些都是示例.. http://android-coding.blogspot.in/2013/04/example-to-use-youtubeplayerfragment-of.html http://android-er.blogspot.in/2013/06/example-to-use-youtubeplayerfragment-of.html

我无法理解如何使用YouTubePlayerFragment，以便我的类扩展Fragment而不是我的项目中所需的YouTubeBaseActivity。如下所示，我的课程扩展了另一项活动并包含导航抽屉，其中第五个选项打开YouTube片段我想在这个片段中播放Youtube视频。我简要介绍了我的课程 -

public class LandingActivity extends BaseGActivity {
.

public void selectDrawerItem(int position) {

        Bundle args = new Bundle();

        switch (position) {

布局

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <fragment
        android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
        android:id="@+id/youtube_fragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
</LinearLayout>

错误 -

Error:(64, 101) error: <anonymous com.pc.gi.ui.fragment.YoutubeFragment$1> is not abstract and does not override abstract method onInitializationFailure(Provider,YouTubeInitializationResult) in OnInitializedListener

Answer 1

首先将您的活动正常扩展

 class YourActivity extends Activity...

布局文件中的

放下以下行

<fragment
  android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
  android:id="@+id/youtube_fragment"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"/>

然后在您的Activity中，您可以使用片段的onCreareView方法中的下一行创建其实例。

YouTubePlayerSupportFragment youTubePlayerFragment = (YouTubePlayerSupportFragment) getActivity().getSupportFragmentManager()
                    .findFragmentById(R.id.youtube_fragment);

或者您可以在xml中声明FrameLayout，然后使用以下行启动YouTubeSupportFragment

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <FrameLayout
        android:id="@+id/youtube_fragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerHorizontal="true"
        android:visibility="visible" />

</RelativeLayout>

onCreateView中的代码

 YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();

    youTubePlayerFragment.initialize("DEVELOPER_KEY", new OnInitializedListener() {

        @Override
        public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {

            if (!wasRestored) {
                YPlayer = player;
                YPlayer.setFullscreen(true);
                YPlayer.loadVideo("2zNSgSzhBfM");
                YPlayer.play();
            }

        }

        @Override
        public void onInitializationFailure(Provider arg0, YouTubeInitializationResult arg1) {
            // TODO Auto-generated method stub

        }
    });
    FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
    transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();

这里的关键是使用YouTubePlayerSupportFragment代替YouTubePlayerFragment。

希望这有帮助。

            }
        });

    }
}

Answer 2

要使用片段实现youtube播放器，请执行以下3个步骤：-

在活动XML文件中添加以下内容：

 <fragment
         android:name="com.google.android.youtube.player.YouTubePlayerFragment"
         android:id="@+id/youtube_fragment"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"/>

在活动Java文件中创建一个新的OnInitialize侦听器

YouTubePlayer.OnInitializedListener onInitializedListener = new 
YouTubePlayer.OnInitializedListener() {
     @Override
     public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {

         youTubePlayer.loadVideo("Your_video_id");



     }

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

     }
 };

初始化监听器后，获取片段引用并初始化播放器。

YouTubePlayerFragment youTubePlayerFragment = (YouTubePlayerFragment) getFragmentManager().findFragmentById(R.id.youtube_fragment);
youTubePlayerFragment.initialize("You_Developer_Api_Key", onInitializedListener);

要获取开发人员API密钥，请遵循此link。
