处理当前活动的Android推送通知

Question

我已经实现了Android推送通知，我可以在应用程序运行时使用此方法扩展Firebase MessagingService来处理它：

@Override
public void onMessageReceived(@NonNull RemoteMessage remoteMessage) {
   ...
}

但我真正需要的是在我当前的活动中获取通知数据，以更新一些字段，以便用户实时查看。但我找不到一个方法来做到这一点。有人能帮帮我吗？

Answer 1

请查看文档：

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());
        updateData(remoteMessage.getData());

    }

}



public void updateData(Map<String, String> data){
        // update your data here
        //ex: editText1.setText("text");
    }

创建本地广播接收器
当您在FirebaseMessagingService收到通知时，您将使用LocalBroadcastReceiver将数据发送到所需的活动。这既简单又安全。

在FirebaseMessagingService上

@Override
public void onMessageReceived(@NonNull RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);

//Take the data from message received
String myData = remoteMessage.get("MyDataKey");

//Send data through a local broadcast receiver
Intent intent = new Intent("IntentFilterAction");
intent.putExtra("MyDataKey", myData);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

关于活动onCreate

//Create BroadcastReceiver
BroadcastReceiver broadcastReceiver = new BroadcastReceiver(){
      @Override
      public void onReceive(Context context, Intent intent) {
          super.onReceive(context, intent);

          //Get data from intent
          String mydata = intent.getExtras
      }
};

IntentFilter intentFilter = new IntentFilter("IntentFilterAction");
LocalBroadcastManager.getInstance(getContext()).registerReceiver(broadcastReceiver, intentFilter);

活动onDestroy

//Unregister BroadcastReceiver
LocalBroadcastManager.getInstance(getContext()).unregisterReceiver(broadcastReceiver);
