使用firebase（Android）

Question

您好我一直关注this tutorial和this来生成并接收Android中的推送通知。我已经阅读了很多关于此的帖子，所以这可能是一个重复的问题，但我是android的新手，所以请耐心等待。当我的应用程序在前台时，应用程序显示我在广播接收器中写的吐司，但是当它在后台时，不调用广播接收器。以下是我的各种活动：

MyFirebaseInstanceIdService

import android.content.Intent;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import android.support.v4.content.LocalBroadcastManager;
import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;

public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

private static final String TAG = "MyFirebaseIIDService";

@Override
public void onTokenRefresh() {

    //Getting registration token
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();

    //Displaying token on logcat
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    //calling the method store token and passing token
    storeToken(refreshedToken);
    Log.i("token here",refreshedToken);
    Intent registrationComplete = new Intent(Config.REGISTRATION_COMPLETE);
    registrationComplete.putExtra("token", refreshedToken);
    LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete);

}

private void storeToken(String token) {
    //we will save the token in sharedpreferences later
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
    SharedPreferences.Editor editor = prefs.edit();
    Log.i("token in shared",token);
    editor.putString("token", token);
    editor.commit();
}
}

MyFirebaseMessagingService

我主要活动中的Brodadcast接收器

    mRegistrationBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {

            // checking for type intent filter
            if (intent.getAction().equals(Config.REGISTRATION_COMPLETE)) {
                // gcm successfully registered

                // now subscribe to `global` topic to receive app wide notifications
                FirebaseMessaging.getInstance().subscribeToTopic(Config.TOPIC_GLOBAL);



            } else if (intent.getAction().equals(Config.PUSH_NOTIFICATION)) {
                // new push notification is received

                String message = intent.getStringExtra("message");
                //  Map<String,String> notificationDataMap
                //        = intent.getSerializableExtra("notification_data");
                Toast.makeText(getApplicationContext(), "Push notification: " + message, Toast.LENGTH_LONG).show();
                Log.i("push push",message);
 //display in list .get data from messagin activity anad display here

            }
        }
    };

问题

我应该对我的php文件进行哪些更改才能打开主活动并在点击推送通知时显示弹出窗口或对话框？

提前致谢。

我修好了。刚刚使用了click_action，就像许多其他帖子所建议的那样，并将活动更改为我需要调用的活动。
