Answer 1

기본 UI 스레드에서 parentsActivity.startChildActivity("MerchantActivity", edit);을 실행 해보십시오. 이런 식으로 뭔가가 :

runOnUiThread(new Runnable() { 
    public void run() { 
     parentsActivity.startChildActivity("MerchantActivity", edit); 
    } 
}); 

BTW, 당신은 이것에 대한 final로 TabGroupActivity parentsActivity 및 Intent edit를 선언해야합니다.

Answer 2

귀찮아, 내가 찾고있는 대답을 찾았습니다. 방금 ​​추가하면 매력처럼 작동합니다.

   runOnUiThread(new Runnable() { 
           public void run() { 
           // Toast.makeText(activity, "Hello", Toast.LENGTH_SHORT).show(); 
           Intent edit = new Intent(getParent(), MerchantActivity.class); 
           TabGroupActivity parentsActivity = (TabGroupActivity)getParent(); 
           parentsActivity.startChildActivity("MerchantActivity", edit); 
           } 
          });
