谷歌滑動菜單與操作欄sherlock單獨的片段菜單項

當試圖與操作欄sherlock實施谷歌滑動菜單時，我得到這個錯誤。我想爲每個片段分別提供菜單項。它在onCreateOptions菜單和onOptionsItemSelected中給我這個錯誤，但只在Fragment中;在FragmentActivity它運行良好。谷歌滑動菜單與操作欄sherlock單獨的片段菜單項

The method onCreateOptionsMenu(Menu, MenuInflater) of type Fragment_1 must override or implement a supertype method

這是片段

import com.actionbarsherlock.view.Menu; 
import com.actionbarsherlock.view.MenuInflater; 
import com.actionbarsherlock.view.MenuItem; 
import android.support.v4.app.Fragment; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 

public class Fragment_1 extends Fragment{ 


@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setHasOptionsMenu(true); 
} 

// ... 

@Override 
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { 
    inflater.inflate(R.menu.find_movie, menu); 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // ... 
} 


}

代碼這是片段活動的代碼。不確定它是否與問題相關。

public class MainActivity extends SherlockFragmentActivity { 
private DrawerLayout mDrawerLayout; 
private ListView mDrawerList; 
private ActionBarDrawerToggle mDrawerToggle; 

private CharSequence mDrawerTitle;

忘了，而不是延長片段的SherlockFragment

public class Fragment_1 extends Fragment應該是 public class Fragment_1 extends SherlockFragment {
