TabGroupActivity - startChildActivity - 작동하지 않습니다.

Question

TabActivity을 사용하고 있으며 모든 하위 활동에 탭을 표시하려고합니다. 내가 좋아하는 흐름을 한이 MainActivity(TabActivity) ->TabGroupActivity1(TabGroupActivity) ->Activity1 ->

지금은 플래그가 true 인 경우에만 activity2에에 리디렉션 할 Activity2. 그래서 내 코드는 다음과 같습니다.

TabGroupActivity 

    public class TabGroupActivity extends ActivityGroup { 

    private ArrayList<String> mIdList; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState);  
     if (mIdList == null) mIdList = new ArrayList<String>(); 
    } 

    /** 
    * This is called when a child activity of this one calls its finish method. 
    * This implementation calls {@link LocalActivityManager#destroyActivity} on the child activity 
    * and starts the previous activity. 
    * If the last child activity just called finish(),this activity (the parent), 
    * calls finish to finish the entire group. 
    */ 
    @Override 
    public void finishFromChild(Activity child) { 
     LocalActivityManager manager = getLocalActivityManager(); 
     int index = mIdList.size()-1; 

     if (index < 1) { 
      finish(); 
      return; 
     } 

     manager.destroyActivity(mIdList.get(index), true); 
     mIdList.remove(index); index--; 
     String lastId = mIdList.get(index); 
     Intent lastIntent = manager.getActivity(lastId).getIntent(); 
     Window newWindow = manager.startActivity(lastId, lastIntent); 
     setContentView(newWindow.getDecorView()); 
    } 

    /** 
    * Starts an Activity as a child Activity to this. 
    * @param Id Unique identifier of the activity to be started. 
    * @param intent The Intent describing the activity to be started. 
    * @throws android.content.ActivityNotFoundException. 
    */ 
    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); 
      setContentView(window.getDecorView()); 
     }  
    } 

    /** 
    * The primary purpose is to prevent systems before android.os.Build.VERSION_CODES.ECLAIR 
    * from calling their default KeyEvent.KEYCODE_BACK during onKeyDown. 
    */ 
    @Override 
    public boolean onKeyDown(int keyCode, KeyEvent event) { 
     if (keyCode == KeyEvent.KEYCODE_BACK) { 
      //preventing default implementation previous to android.os.Build.VERSION_CODES.ECLAIR 
      return true; 
     } 
     return super.onKeyDown(keyCode, event); 
    } 

    /** 
    * Overrides the default implementation for KeyEvent.KEYCODE_BACK 
    * so that all systems call onBackPressed(). 
    */ 
    @Override 
    public boolean onKeyUp(int keyCode, KeyEvent event) { 
     if (keyCode == KeyEvent.KEYCODE_BACK) { 
      onBackPressed(); 
      return true; 
     } 
     return super.onKeyUp(keyCode, event); 
    } 

    /** 
    * If a Child Activity handles KeyEvent.KEYCODE_BACK. 
    * Simply override and add this method. 
    */ 
    @Override 
    public void onBackPressed () { 
     int length = mIdList.size(); 
     if (length > 1) { 
      Activity current = getLocalActivityManager().getActivity(mIdList.get(length-1)); 
      current.finish(); 
     } 
    } 
} 

이제 코드 Activity1

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 

     if(flag){ 
      TabGroupActivity parentActivity = (TabGroupActivity)getParent(); 
      Intent previewMessage = new Intent(parentActivity, Activity2.class); 
      parentActivity.startChildActivity("Activity2", previewMessage); 
     }else{ 
      setContentView(R.layout.row); 
      //... 
     } 
    } 

이 작동하지 않습니다 지금 TabGroupActvity1

public class TabGroupActyvity1 extends TabGroupActivity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     startChildActivity("OptionsActivity", new Intent(this,Activity1.class)); 
    } 


} 

,

같은 코드 일부 클릭 이벤트에서 울부 짖는 작품의 하나지만 내 경우 엔 작동하지 않아.

TabGroupActivity parentActivity = (TabGroupActivity)getParent(); 
Intent previewMessage = new Intent(parentActivity, Activity2.class); 
parentActivity.startChildActivity("Activity2", previewMessage); 

제안 방법을 알려주세요. 문제를 잘 설명해 주어야합니까 ... 자세한 내용을 추가해야합니까?

Answer 1

그래, 나는 다른 대안을 발견했다.

대신 ... 하위 작업의 플래그를 확인하고 다른 페이지로 리디렉션합니다.

나는이

if (getLNApplication().isLogin()) { 
    startChildActivity("Report", new Intent(this, ReportActivity.class)); 
}else{ 
    startChildActivity("LogIn", new Intent(this, LoginActivity.class)); 
} 

마찬가지로 parnt 활동에 플래그를 확인하고 및 로그인에 성공한 LoginActivity에서 내가 우는 소리

parentActivity.startChildActivity("EditActivity", new Intent(getParent(), ReportActivity.class)); 

같은 ReportActivity을 시작하고 나는 또한 현재의 뒷면을 눌러 처리 사용자가 다시 로그인 페이지로 돌아가 길 원치 않습니다. 내가 만약이

@Override 
public void onBackPressed() { 
    int length = mIdList.size(); 
    if (length > 1) { 
     Activity current = getLocalActivityManager().getActivity(
       mIdList.get(length - 1)); 
     // Added code to disable back press only for the ReportActivity 
     if(current instanceof ReportActivity){ 
      Log.i("TabGroup", "I am instance of ReportActivity"); 
      return; 
     } 
     current.finish(); 
    } 
}
