Java 如何在Android中使用YoutubeAndroidAPI中的Fragment？

在android中使用YoutubeAndroidApi时，如何在视频应用程序中使用片段

请参考此代码，并建议我。。。 比你先

MainActivity.java

activity_main.xml

screen1_fragment.xml

---

很抱歉，这不是复制的问题。main.xml文件中存在一些问题。。错误是：错误膨胀类碎片Post错误堆栈tracejava.lang.RuntimeException:无法启动活动组件信息{com.youtubedemofragment/com.youtubedemofragment.Main}:android.view.InflateException:二进制XML文件第12行错误膨胀类碎片请参见问题。

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

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
