调用内startActivity（intentServiceIntent）（夏洛特）DialogFragment导致ActivityNotFoundException

Question

场景：

SherlockFragmentActivity显示SherlockFragment。 SherlockFragment显示SherlockDialogFragment。

Verions：

• 生成API：谷歌API的15
• 兼容性/支持包：V4
• ActionBarSherclock：4.1.0
• Android模拟器：API-8

代码：

SherlockFragmentActivity：

public class TrailerDetailSherlockFragmentActivity extends SherlockFragmentActivity { 
    ... 
    /* 
    * set up the fragment which will display the sensor details, 
    * and allow changes of the alarm settings 
    */      
    detailFragment = new TempsensorDetailSherlockFragment(); 

    transaction = getSupportFragmentManager().beginTransaction(); 
    transaction.replace(R.id.framelayout_td_sensordetail, detailFragment); 
    transaction.commit(); 
    ... 
    } 

SherlockFragment：

public class TempsensorDetailSherlockFragment extends SherlockFragment { 
    ... 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     ... 
     // set the onClick method for the alarm values 
     View alarmValueLayout = tempsensorDetailView.findViewById(R.id.ll_sd_minmax); 
     alarmValueLayout.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 

       FragmentManager fm = activity.getSupportFragmentManager(); 

       // Create and show the dialog. 
       SetAlarmTemperatureSherlockDialogFragment setAlarmTempsDialogFragment = new SetAlarmTemperatureSherlockDialogFragment(deviceString, alarm); 
       setAlarmTempsDialogFragment.show(fm, "dialog"); 
      } 
     }); 
     ... 
    } 

SherlockDialogFragment：

public class SetAlarmTemperatureSherlockDialogFragment extends SherlockDialogFragment { 
    ... 
    @Override 
    public void onAttach(Activity activity) { 
     ... 
     this.activity = (SherlockFragmentActivity) activity; 
     notificationServiceUtil = new NotificationServiceUtil(activity); 
     ... 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    ... 
    saveButton = (ImageButton) view.findViewById(R.id.btn_setalarmtemp_save); 
      saveButton.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 

        ... 
        notificationServiceUtil.alarmSubscribe(deviceString, bundle, new AlarmSubscribeHandler()); 
       } 
      }); 
    ... 
    } 

对于后台作业和数据管理，我使用的是IntentService。 因此，我创建了一个名为NotificationServiceUtil一个辅助类：清单的

public class NotificationServiceUtil { 
    ... 
    public NotificationServiceUtil(Activity activity) { 
     this.activity = activity; 
    } 

    private void _initRestApiServiceIntent (String action) { 
     restApiServiceIntent = new Intent(activity, NotificationService.class); 
     restApiServiceIntent.setAction(action); 
    } 

    public void alarmSubscribe(String deviceString, Bundle bundle, Handler handler) { 
     _initRestApiServiceIntent(NotificationService.ACTION_ALARM_SET); 
     restApiServiceIntent.putExtras(bundle); 
     restApiServiceIntent.putExtra(NotificationService.EXTRAKEY_DEVICE_STRING, deviceString); 
     restApiServiceIntent.putExtra(NotificationService.EXTRAKEY_MESSENGER, new Messenger(handler)); 

     activity.startActivity(restApiServiceIntent); 
    } 
    ... 
} 

部分：

<activity 
     android:name=".activitys.MainSherlockFragmentActivity" 
     android:label="@string/app_name"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 

    <activity 
     android:name=".activitys.TrailerDetailSherlockFragmentActivity" 
     android:label="@string/app_name"/> 

    <service android:name=".services.NotificationService" /> 

例外：

这是我得到的例外，当单击SetAlarmTemperatureSherlockDialogFragment中的保存按钮：

个

思考：

，你可以在异常看到的是，startActivityForResult（）被调用，而不是startActivity（）。 我认为这可能是support.v4包中的一个错误，但我不确定。

但我可以说的是，NotificationServiceUtil类从例如活动和SherlockFragmentActivity。

有没有人有一个想法如何解决这个问题？

Answer 1

你开始服务，而不是一个活动。将activity.startActivity（）更改为activity.startService（）

Answer 2

刚查的变化，我对我们的代码， 制成，不要忘记导入

import android.app.NotificationManager; // in ur activity 

public class NotificationServiceUtil { 
    ... 
    public NotificationServiceUtil(Activity activity) { 
     this.activity = activity; 
    } 

    private void _initRestApiServiceIntent (String action) { 
     NotificationManager nm = (NotificationManager) getSystemService(activity.NOTIFICATION_SERVICE); <------ CHANGE 
     restApiServiceIntent = new Intent(activity, nm.getClass()); <--- CHANGE 
     restApiServiceIntent.setAction(action); 
    } 
    public void alarmSubscribe(String deviceString, Bundle bundle, Handler handler) { 
     _initRestApiServiceIntent(NotificationService.ACTION_ALARM_SET); 
     restApiServiceIntent.putExtras(bundle); 
     restApiServiceIntent.putExtra(NotificationService.EXTRAKEY_DEVICE_STRING,  deviceString); 
     restApiServiceIntent.putExtra(NotificationService.EXTRAKEY_MESSENGER, new Messenger(handler)); 

    activity.startActivity(restApiServiceIntent); 
} 
... 
}
