如何覆盖ParsePushBroadcastReceiver的onPushReceive()？

Question

我正在使用Parse.com的推送通知服务.根据文件:

覆盖onPushReceive以触发"静默"推送的后台操作

我在这里找到了onPushOpen()的源代码,但现在我必须重写onPushReceive()来自定义声音和振动的行为.我不知道我应该在onPushReceive()中做什么,是否有任何示例代码可以帮助我找出onPushReceive()中的逻辑？谢谢.

创建一个扩展ParsePushBroadcastReceiver的新类:

public class MyPushBroadcastReceiver extends ParsePushBroadcastReceiver {

public static final String PARSE_DATA_KEY = "com.parse.Data";

   @Override
   protected Notification getNotification(Context context, Intent intent) {
      // deactivate standard notification
      return null;
   }

   @Override
   protected void onPushOpen(Context context, Intent intent) {
      // Implement       
   }  

   @Override
   protected void onPushReceive(Context context, Intent intent) {
      JSONObject data = getDataFromIntent(intent);
      // Do something with the data. To create a notification do:

      NotificationManager notificationManager =
      (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

      NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
      builder.setContentTitle("Title");
      builder.setContentText("Text");
      builder.setSmallIcon(R.drawable.ic_notification);
      builder.setAutoCancel(true);

      // OPTIONAL create soundUri and set sound:
      builder.setSound(soundUri);

      notificationManager.notify("MyTag", 0, builder.build());

   }

   private JSONObject getDataFromIntent(Intent intent) {
      JSONObject data = null;
      try {
         data = new JSONObject(intent.getExtras().getString(PARSE_DATA_KEY));
      } catch (JSONException e) {
         // Json was not readable...
      }
      return data;
   }
}

在你的Manifest中添加:

  <receiver
     android:name=".MyPushBroadcastReceiver"
     android:exported="false">
     <intent-filter>
        <action android:name="com.parse.push.intent.RECEIVE" />
        <action android:name="com.parse.push.intent.DELETE" />
        <action android:name="com.parse.push.intent.OPEN" />
     </intent-filter>
  </receiver>
