使用ActionBarSherlock的每个选项卡片段的操作栏菜单

Question

我在使用ActionBarSherlock API获取使用ActionBarSherlock API的每个片段的选项菜单时遇到了一些麻烦。

我已经把我的setHasOptionsMenu(true)里面onCreateView，但onCreateOptionsMenu内片段不会被调用。

我的主要活动

public class EvolutionActivity extends TabActivity { 

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

    @Override 
    protected void onResume() { 
    // TODO Auto-generated method stub 
    super.onResume();  
     addTab(getResources().getString(R.string.fragment_measurement_title), TabFragmentMeasurement.class, null); 
     addTab(getResources().getString(R.string.fragment_workout_title) , TabFragmentWorkout.class, null); 
     addTab(getResources().getString(R.string.fragment_exercise_title), TabFragmentExercise.class, null); 
    } 

} 

标签活性抽象类TabActivity.class

public abstract class TabActivity extends SherlockFragmentActivity { 

private ViewPager mViewPager; 
private TabsAdapter adapter; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    /* 
    * Create the ViewPager and our custom adapter 
    */ 
    mViewPager = new ViewPager(this); 
    adapter = new TabsAdapter(this, mViewPager); 
    mViewPager.setAdapter(adapter); 
    mViewPager.setOnPageChangeListener(adapter); 

    /* 
    * We need to provide an ID for the ViewPager, otherwise we will get an exception like: 
    * 
    * java.lang.IllegalArgumentException: No view found for id 0xffffffff for fragment TabFragmentMeasurement{40de5b90 #0 id=0xffffffff android:switcher:-1:0} 
    * at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:864) 
    * 
    * The ID 0x7F04FFF0 is large enough to probably never be used for anything else 
    */ 
    mViewPager.setId(0x7F04FFF0); 

    super.onCreate(savedInstanceState); 

    /* 
    * Set the ViewPager as the content view 
    */ 
    setContentView(mViewPager); 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // TODO Auto-generated method stub 
    switch (item.getItemId()) { 
    case R.id.action_settings:{ 
     Intent intent = new Intent(this, ParametersActivity.class); 
     startActivity(intent); 
     break; 
    } 
    } 
    return super.onOptionsItemSelected(item); 
} 

/** 
* Add a tab with a backing Fragment to the action bar 
* @param titleRes A string resource pointing to the title for the tab 
* @param fragmentClass The class of the Fragment to instantiate for this tab 
* @param args An optional Bundle to pass along to the Fragment (may be null) 
*/ 
protected void addTab(int titleRes, Class fragmentClass, Bundle args) { 
    adapter.addTab(getString(titleRes), fragmentClass, args); 
} 
/** 
* Add a tab with a backing Fragment to the action bar 
* @param titleRes A string to be used as the title for the tab 
* @param fragmentClass The class of the Fragment to instantiate for this tab 
* @param args An optional Bundle to pass along to the Fragment (may be null) 
*/ 
protected void addTab(CharSequence title, Class fragmentClass, Bundle args) { 
    adapter.addTab(title, fragmentClass, args); 
} 

我的片段TabFragmentMeasurement.class

public class TabFragmentMeasurement extends Fragment { 

....... // Class' attributes 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 

     setHasOptionsMenu(true); 

     TextView txt = new TextView(inflater.getContext()); 

     ....... // Change TextView's attributes 

     return txt; 
} 


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

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle presses on the action bar items 
    switch (item.getItemId()) { 

    case R.id.item_add_measurement:{ 

       // Add a measurement 

    } 
    default: 
     return super.onOptionsItemSelected(item); 
    } 
} 
} 

XML菜单文件measurement.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" > 

<item 
    android:id="@+id/action_settings" 
    android:orderInCategory="100" 
    android:showAsAction="never" 
    android:title="@string/action_settings"/> 
<item 
    android:id="@+id/item_add_measurement" 
    android:icon="@android:drawable/ic_menu_add" 
    android:orderInCategory="1" 
    android:showAsAction="ifRoom" 
    android:title="@string/item_add_measurement"/> 

</menu>

你为什么不延长SherlockFragment在fragment类？ 请记住，您传递的每个环境都像“this”一样：

this.getSherlockActivity().
