推荐答案

是的，这是可能的。 Parse.com文件说：

Yes, it's possible. Parse.com documentation says:

您还可以指定一个Intent在后台被解雇时，推送通知是
  好评。这将使您的应用程序执行自定义处理的通知，并
  可用于无论是否选择了显示系统托盘消息。为了实现
  自定义通知的处理，您在您的推送通知的数据录入行动
  词典要火意图的行动。 Android的指南建议，
  您preFIX您的包名的行动，以避免与其他命名空间冲突
  正在运行的应用。

You can also specify an Intent to be fired in the background when the push notification is received. This will allow your app to perform custom handling for the notification, and can be used whether or not you have chosen to display a system tray message. To implement custom notification handling, set the Action entry in your push notification data dictionary to the Intent action which you want to fire. Android guidelines suggest that you prefix the action with your package name to avoid namespace collisions with other running apps.

所以，你用这种方式发送推送通知：

So you send push notifications in this way:

JSONObject data = new JSONObject("{\"action\": \"com.example.UPDATE_STATUS\""}));

ParsePush push = new ParsePush();
push.setData(data);
push.sendPushInBackground();

然后在你的Andr​​oidManifest.xml中注册一个广播接收器，只要用com.example.UPDATE_STATUS的操作参数收到一个推送通知将被调用：

Then in your AndroidManifest.xml register a broadcast receiver that will be called whenever a push notification is received with an action parameter of com.example.UPDATE_STATUS:

<receiver android:name="com.example.MyBroadcastReceiver" android:exported="false">
  <intent-filter>
    <action android:name="com.example.UPDATE_STATUS" />
  </intent-filter>
</receiver>

在你的广播接收器，你就可以开始一个新的活动：

In your broadcast receiver you can start a new activity:

public class MyBroadcastReceiver extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {
    context.startActivity(new Intent(context, MyActivity.class));
  }
}
