java - AndroidのYoutubeAndroidAPIでフラグメントを使用するには?

Question

AndroidでYoutubeAndroidApiを使用する場合、ビデオアプリケーションでフラグメントを使用するにはどうすればよいですか?

このコードを参照して、私に提案してください...事前にあなたより..

MainActivity.java

import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

public class Main extends FragmentActivity {

    @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;
    }

}
