您创建YouTubePlayer对象的方式而不是那种方式尝试以下代码：

<强> activity_main.xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:layout_gravity="center"
    android:gravity="center_horizontal">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello YouTube API"
        android:layout_margin="12dip"/>

   <com.google.android.youtube.player.YouTubePlayerView
              android:id="@+id/youtube_view"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_margin="12dip"/>

</LinearLayout>

<强> MainActivity.java

public class MainActivity extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener {

       static private final String DEVELOPER_KEY = "add your own key here!";
       static private final String VIDEO = "4SK0cUNMnMM";

         @Override
         protected void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              setContentView(R.layout.activity_main);

              YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
              youTubeView.initialize(DEVELOPER_KEY, this);
         }

         @Override

         public void onInitializationFailure(Provider provider, YouTubeInitializationResult error) {
                Toast.makeText(this, "Error : " + error.toString(), Toast.LENGTH_LONG).show();
         }

         @Override

         public void onInitializationSuccess(Provider provider, YouTubePlayer player, boolean wasRestored) {
              player.loadVideo(VIDEO);
         }

}

AndroidManifest.xml中的权限

<uses-permission android:name="android.permission.INTERNET"/>

无法播放不同活动的Youtube视频
