AsyncTask를 publishProgress는 onProgressUpdate가

이미이 문제에 대한 모든 유사한 스레드에 보면 한 전화 해달라고,하지만 난 내 문제에 대한 해결책을 찾을 수 없습니다AsyncTask를 publishProgress는 onProgressUpdate가

보관함에서 파일을 다운로드 및 통지의 진행 상황을 표시해야 내 AsynkTask 진행 표시 줄. doInBackground는 파일을 다운로드하지만 publishProgress/onProgressUpdate 메소드가 제대로 작동하지 않습니다. onProgressUpdate가 호출되지 않습니다.

나는 모든 것을 시도했다. DoinBackground가 끝난 후에도 onProgressUpdate와 같은 여러 가지 효과가 여러 번 호출되었습니다. 그러나 그 순간에 전화를받지 못했습니다. 또한 소켓 닫기 예외를 설명 할 수 없습니다. =/

희망을 보내 주시면 감사하겠습니다. 이미 전체 프로젝트를 다시 만들고 다시 설치하려고했습니다. 그러나 그것은 효과가 없었습니다.

감사합니다.

는'publishProgress'는 주 응용 프로그램 스레드에 메시지를 보낸다는'handleMessage' 재정이'onProgressUpdate'를 호출, 나는 당신이이 주 응용 프로그램 스레드가 아닌 다른 스레드에서 메서드를 실행 호출하는 것 같아요 , 스레드가 메인 애플리케이션 스레드를 차단하고 있으며, 마지막으로 차단 해제되면 'onProgressUpdate'에 대한 보류중인 호출이 처리됩니다. [this] (https://github.com/android/platform_frameworks_base/blob/master/core/java/android/os/AsyncTask.java)를 확인하고,'private static class InternalHandler extends Handler'를 찾아보십시오. 메세지 루퍼는'Looper.getMainLooper()' –

내 POC를 사용해보십시오. 도움이됩니다.

public class MainActivity extends Activity { 처리기 처리기 = 새 처리기();

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    new BackGroundTask().execute(""); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

class BackGroundTask extends AsyncTask<String, String, String> { 

    @Override 
    protected String doInBackground(String... params) { 
     // TODO Auto-generated method stub 

     Thread t = new Thread(new Runnable() { 

      @Override 
      public void run() { 
       // TODO Auto-generated method stub 
       for (int i = 0; i < 10; i++) { 
        try { 
         Thread.sleep(1000); 
        } catch (InterruptedException e) { 
         // TODO Auto-generated catch block 
         e.printStackTrace(); 
        } 
        publishProgress("" + i); 
       } 
      } 
     }); 
     t.start(); 

     return null; 
    }

입니다. IntentService에서 asynctask를 호출했기 때문일 수 있습니다. – Stefan

@Stefan AsyncTask는 메인 UI 작업에서만 호출되기 때문에 질문의 intentservice에서 호출한다고 언급해야합니다. –

이제 정상적인 서비스로 변경했습니다. 그러나 이제 OnProgressUpdate는 doInBackground 다음에 여러 번 호출됩니다. publishProgress가 호출 될 때마다 호출해야합니까? – Stefan
