Android的活動組 - 第二活動始終顯示第一個活動菜單

Question

我使用的ActivityGroup一個問題。我有兩個ActivityGroup內的活動，他們都使用菜單（覆蓋onCreateOptionMenu和onOptionsItemSelected）。

兩個活動有不同的菜單。

好了，問題是，第二活動始終顯示第一個活動菜單，

有關此問題的任何想法？

下面是我的代碼

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; 
    } 
}

當您添加活動，「當前」活動是最後一個加入。我懷疑，如果你與其他活動互動，然後激活它將工作的選項菜單。

嘗試獲取你需要用字符串ID的活動：

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