android AsyncTask xml parsing

Question

나는 AsyncTask에서 큰 XML 문서를 구문 분석하려고합니다. FeinstaubActivity가 시작되지만 검은 화면 만보고 다른 활동을 시작한 RSSReaderActivity로 돌아갑니다.

코드

Document document = null; 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.feinstaub); 
      document = (Doxument) new ParseXMLFile().execute(); 
    } 

    private class ParseXMLFile extends AsyncTask<Integer, Integer, Document>{ 

    @Override 
    protected Document doInBackground(Integer... params) { 
     Document parsedXML = null; 
     try { 
      parsedXML = builder.parse(getApplicationContext().getResources().openRawResource(R.raw.finedust)); 
     } catch (NotFoundException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (SAXException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     return parsedXML; 
    }

아, 확실하지 당신은 할 수 있습니다 : 무효 수익을 실행 http://developer.android.com/reference/android/os/AsyncTask.html을 보여줍니다.

이 원하는 :

당신이해야 할 범위 지정의 조금있다

Document document = null; 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.feinstaub); 
     new ParseXMLFile().execute(); 
    } 

    void setDocument(Document document){ this.document = document; } 

    private class ParseXMLFile extends AsyncTask<Integer, Integer, Document>{ 
    @Override public void onPostExecute(Document d){ setDocument(d); } 

    @Override 
    protected Document doInBackground(Integer... params) { 
     Document parsedXML = null; 
     try { 
      parsedXML = builder.parse(getApplicationContext().getResources().openRawResource(R.raw.finedust)); 
     } catch (NotFoundException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (SAXException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     return parsedXML; 
    } 

} 

:의 부모 활동을 통과하거나 AsyncTask를 내부에서 다시 호출 할 수 있도록 적절하게 어떻게 든 setDocument 방법을 선언하지만, 뭔가 그게 그렇게해야합니다.
