Android AsyncTask : 각 뷰 페이지 조각에 대한 비동기 작업

Question

나는 viewpager과 FragmentStatePagerAdapter입니다. 그리고 Fragment에 계산 프로세스가 있으므로 Fragment에 AsyncTask을 사용했습니다. 이 단편은 FragmentStatePagerAdapter에서로드됩니다. 조각의 스냅 코드는 다음과 같습니다.

public void refreshView() { 
     if(asynTask == null) { 
      asynTask = new SetupTableTask(); 
     } 
     asynTask.execute(); 
    } 

    private class SetupTableTask extends AsyncTask<Void, Void, Void> { 

     @Override 
     protected Void doInBackground(Void... arg0) { 
      setupInitialValue(); 
      dashboradView.removeAllViews(); 
      setupTableRow(); 
      return null; 
     } 

     @Override 
     protected void onPostExecute(Void result) { 
      progressDialog.dismiss(); 
     } 

     @Override 
     protected void onPreExecute() { 
      progressDialog = ProgressDialog.show(getActivity(), "Dashboard", 
        " Loading...", true, false); 
     } 
    } 

문제는 4 또는 5 페이지를 빠르게 스 와이프 할 때입니다. 이 예외가 있습니다.

ViewPager의 조각에서 AsyncTask를 사용할 수 있습니까? 이 예외를 극복하는 아이디어? 나는 이미 Handler을 시도했다. CalledFromWrongThreadException과 같은 예외가 있습니다.

감사

Answer 1

당신은 결합 또는 doInBackground 에서 제거하고 onPostExecute에 넣고 여기에 당신이 당신의 조회수
