AsyncTask의 화면 방향 처리

Question

내 응용 프로그램에서 AsyncTask를 사용하고 있습니다.

오리엔테이션이 변경 되더라도 작업을 재개하려면 어떻게해야합니까?

이 작업은 : -

package com.android.grad; 

import android.app.Activity; 
import android.app.ProgressDialog; 
import android.content.Intent; 
import android.net.Uri; 
import android.os.AsyncTask; 
import android.provider.MediaStore; 

public class LoginTask extends AsyncTask<Void, Void, Boolean> { 

    private Activity activity; 
    private ProgressDialog pd; 
    private Uri fileUri; 
    private final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100; 

    public LoginTask(Activity activity, Uri fileUri) { 
     this.activity = activity; 
     this.fileUri = fileUri; 
    } 

    @Override 
    protected void onPreExecute() { 
     pd = ProgressDialog.show(activity, "Signing in", 
       "Please wait while we are signing you in.."); 
    } 

    @Override 
    protected Boolean doInBackground(Void... arg0) { 
     try { 
      Thread.sleep(1000); 
     } catch (InterruptedException e) { 
     } 
     return true; 
    } 

    @Override 
    protected void onPostExecute(Boolean result) { 
     pd.dismiss(); 
     pd = null; 

     Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); 
     activity.startActivityForResult(intent, 
       CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE); 
    } 
}  

public class LoginActivity extends Activity { 

private final int MEDIA_TYPE_IMAGE = 1; 
private CheckBox rememberMe; 
private EditText userName, passWord; 
private Button loginBtn; 
private final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100; 
private String path; 
private Uri fileUri; 

private OnClickListener loginOnClick = new OnClickListener() { 
    public void onClick(View v) { 
     new LoginTask(LoginActivity.this, fileUri).execute(); 
    } 
}; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.login); 

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); 
    path = fileUri.getPath(); 

    loginBtn = (Button) findViewById(R.id.signInBtn); 
    loginBtn.setOnClickListener(loginOnClick); 

    rememberMe = (CheckBox) findViewById(R.id.keepMe); 

    userName = (EditText) findViewById(R.id.userNameID); 
    passWord = (EditText) findViewById(R.id.passwordID); 
} 

@Override 
protected void onResume() { 
    super.onResume(); 
    SharedPreferences sp = getSharedPreferences("user", MODE_PRIVATE); 
    try { 
     userName.setText(sp.getString("username", "")); 
     passWord.setText(sp.getString("password", "")); 
     rememberMe.setChecked(sp.getBoolean("rememberMe", false)); 
    } catch (ClassCastException ex) { 
    } 
} 

@Override 
protected void onPause() { 
    super.onPause(); 

    SharedPreferences sp = getSharedPreferences("user", MODE_PRIVATE); 
    Editor editor = sp.edit(); 
    if (rememberMe.isChecked()) { 
     editor.putString("username", userName.getText().toString()); 
     editor.putString("password", passWord.getText().toString()); 
    } else { 
     editor.putString("username", ""); 
     editor.putString("password", ""); 
    } 
    editor.putBoolean("rememberMe", rememberMe.isChecked()); 
    editor.commit(); 
} 

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) { 
     if (resultCode == RESULT_OK) { 

      Intent intent = new Intent(LoginActivity.this, 
        PreviewActivity.class); 
      intent.putExtra("path", path); 
      startActivity(intent); 

     } else if (resultCode == RESULT_CANCELED) { 
      // User cancelled the image capture 
      Toast.makeText(getApplicationContext(), 
        "User cancelled the image capture", Toast.LENGTH_LONG) 
        .show(); 
     } else { 
      // Image capture failed, advise user 
     } 
    } 
} 

어떻게 LoginActivity에 있음을 처리 할 수 ​​있습니다. 화면 방향을 지정하면 progressBar 상태를 저장하여 계속 진행할 수 있습니다.

안드로이드 넣어주세요 : configChanges = "오리엔테이션 | keyboardHidden"
