Android的活动组 - 第二活动始终显示第一个活动菜单

Question

我使用的ActivityGroup一个问题。我有两个ActivityGroup内的活动，他们都使用菜单（覆盖onCreateOptionMenu和onOptionsItemSelected）。

两个活动有不同的菜单。

好了，问题是，第二活动始终显示第一个活动菜单，

有关此问题的任何想法？

下面是我的代码

public class myActivityGroup extends ActivityGroup { 

---- 

    public void startChildActivity(String Id, Intent intent) { 
     Window window = getLocalActivityManager().startActivity(Id, intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)); 
     if (window != null) { 
      mIdList.add(Id); 
      View view = window.getDecorView(); 
      history.add(view); 
      setContentView(view); 
     } 
    } 

     public void back() { 
     if (history.size() > 0) { 
      int lastActivityIndex = history.size() - 1; 
      int lastIDIndex = mIdList.size() - 1; 

      String activityId = mIdList.get(lastIDIndex); 
      Log.d(TAG, "activityId:" + activityId); 

      history.remove(lastActivityIndex); 
      mIdList.remove(lastIDIndex); 
      setContentView(history.get(history.size() - 1)); 
     } else { 
      finish(); 
     } 
    } 


@Override 
    public boolean onPrepareOptionsMenu(Menu menu) { 
     Activity current = getLocalActivityManager().getCurrentActivity(); 
     return current.onPrepareOptionsMenu(menu); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     LocalActivityManager manager = getLocalActivityManager(); 
     Activity current = manager.getCurrentActivity(); 
     return current.onCreateOptionsMenu(menu); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     LocalActivityManager manager = getLocalActivityManager(); 
     Activity current = manager.getCurrentActivity(); 
     return current.onOptionsItemSelected(item); 
    } 
} 



public class ChildActivity1 extends Activity { 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     //add menu here 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.settings_menu, menu); 
     return true; 
    } 

    @Override 
     public boolean onOptionsItemSelected(MenuItem item) { 
     //handle on menu item selected here 
     return true; 
    } 
} 



public class ChildActivity2 extends Activity { 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState);  
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     //add menu here 
     MenuInflater inflater = getMenuInflater(); 
     inflater.inflate(R.menu.offer_menu, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     //handle on menu item selected here 
     return true; 
    } 
}

当您添加活动，“当前”活动是最后一个加入。我怀疑，如果你与其他活动互动，然后激活它将工作的选项菜单。

尝试获取你需要用字符串ID的活动：

LocalActivityManager manager = getLocalActivityManager(); 
Activity a = manager.getActivity(id); 
return a.onCreateOptionsMenu(menu);
