내 앱이 조금 지연이를, 그래서 진행률 표시 줄 스피너에 넣어하기로 결정 응용 프로그램을로드하는 동안. 내 코드는 진행률 표시 줄이 약 6 분 동안 회전 한 후에 오류를 표시합니다. 그것은 fileReader()에 오류를 던지고 때로는 그냥 영원히 돌아갑니다. FileReader()는 코드의 핵심 인 또 다른 클래스 파일입니다. 이 수업을 보시려면 클릭하십시오 here 도와주세요. 감사합니다.

발생한 오류에 대한 스택 추적을 게시하십시오. – elevine

체크하기 위해 아래로 스크롤 할 수있는 오류를 넣었습니다. 감사합니다 – ImGeorge

doInBackground 메서드에서 UI를 변경하려고하면 문제가 발생합니다. 근본적인 원인은 아마도 FileReader 클래스가 display.setText(fg); 일 때입니다. doInBackground에있는 동안 수 없습니다은 Acticity's UI로 변경하십시오. 이를 수행하려면 AsyncTask의 publishProgress 및 onProgressUpdate 메소드를 사용해야합니다.

onprogressupdate를 사용하는 방법에 대한 아이디어를 제공 할 수 있습니까? onprogressupdate 클래스 안에 fileReader()를 넣을 수 있습니까? thanks – ImGeorge

AsyncTask Javadoc의 맨 위에는 매우 간단한 예제가 있습니다. http://developer.android.com/reference/android/os/AsyncTask.html. 작업이 doInBackground에서 완료되고 UI 업데이트가 onProgressUpdate에서 수행되도록 fileReader를 해체해야합니다. – elevine

정말 고마워요. Android GUI는 Java Desktop Application에 비해 어렵습니다. – ImGeorge

this.dialog.dismiss();을 if 문에서 제거하고 onPostExecute이 실행될 때마다 대화 상자가 자동으로 닫히도록 할 수 있습니다.

편집 : 내 코드 제안 :

클래스에서 AsyncTask를 실행 :

  ProgressDialog progressDialog = new ProgressDialog(getActivity()); 
      progressDialog.setMessage("Logging in..."); 
      LoginTask loginTask = new LoginTask((Polling) getActivity(), progressDialog); 
      loginTask.execute();

그리고 AsyncTask를 자체 :

public class LoginTask extends AsyncTask<String, Void, Integer> { 

private ProgressDialog progressDialog; 
private Polling activity; 
public LoginTask(Polling activity, ProgressDialog progressDialog) 
{ 
    this.activity = activity; 
    this.progressDialog = progressDialog; 
} 

@Override 
protected void onPreExecute() 
{ 
    progressDialog.show(); 
} 

protected Integer doInBackground(String... arg0) { 
    EditText userName = (EditText)activity.findViewById(R.id.emailEditText); 
    EditText passwordEdit = (EditText)activity.findViewById(R.id.passEditText); 
    String email = userName.getText().toString(); 
    String password = passwordEdit.getText().toString(); 
    UserFunctions userFunction = new UserFunctions(); 
    JSONObject json = userFunction.loginUser(email, password); 

    // check for login response 
    try { 
     if (json.getString(KEY_SUCCESS) != null) { 
      String res = json.getString(KEY_SUCCESS); 

      if(Integer.parseInt(res) == 1){ 
       //whole bunch of extra code! 
       responseCode = 1; 
       // Close Login Screen 
       //finish(); 

      }else{ 
       responseCode = 0; 
       // Error in login 
      } 
     } 

    } catch (NullPointerException e) { 
     e.printStackTrace(); 

    } 
    catch (JSONException e) { 
     e.printStackTrace(); 
    } 

    return responseCode; 
} 

@Override 
protected void onPostExecute(Integer responseCode) 
{ 
    EditText userName = (EditText)activity.findViewById(R.id.emailEditText); 
    EditText passwordEdit = (EditText)activity.findViewById(R.id.passEditText); 

    if (responseCode == 1) { 
     progressDialog.dismiss(); 
     activity.loginReport(responseCode); 
     userName.setText(""); 
     passwordEdit.setText(""); 
     //shared prefences, store name 

    } 
    if (responseCode == 0) { 
     progressDialog.dismiss(); 
     activity.loginReport(responseCode); 

    } 
}

}

그냥 함께 따라가 progressDialog. 그것은 작업을 시작하는 메인 클래스에서 시작하여 AsyncTask에 전달됩니다. 그런 다음 AsyncTask가 구성되면 progressDialog가 AsyncTask의 필드로 저장됩니다. 그런 다음 preExecute에서 progressDialog를 보여줍니다(). 그런 다음 doInBackground의 결과에 따라 onPostExecute에 1 또는 0을 보냅니다. 하나 또는 0은 onPostExecute에게 무엇을해야 하는지를 알려주며, 이는 내 코드에서 대화 상자를 어느 쪽이든 지우지 만 메인 클래스에서 다른 메소드를 실행합니다. 희망이 당신이 자신과 비슷한 작업을 비교하는 데 도움이됩니다.

super.onPostExecute (unused); this.dialog.dismiss(); 나는 그것을 그렇게했다. 하지만 여전히 영원과 같은 회전합니다 – ImGeorge

흠, 제 편집을보고 내 자신의 코드를 비교해보십시오, 도움이 될 수 있습니다. – Davek804

runOnUiThread(new Runnable() { 
@Override 
public void run() { 
// TODO Auto-generated method stub 
if (this.dialog.isShowing()) { 
this.dialog.dismiss(); 
} 
});

doInBackground()의 catch 블록에서 위 코드를 사용하십시오.

위의 코드에서 onPostExecute에서 dialog.dismiss가 호출되고 있습니다.이 코드는 이미 ui 스레드에 있습니다. 이것이 어떻게 도움이되는지 나는 모르겠다. – elevine
