【问题描述】：

下面是我的代码，我正在使用cordova推送通知，我正在尝试合并多个推送通知，但它给了我错误，对于单个通知它的工作，我找不到问题所在，请建议

package org.apache.cordova.firebase;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import android.util.Log;
import android.text.TextUtils;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
import java.util.Map;
import java.util.Random;


private void sendNotification(String id, String title, String messageBody, Map<String, String> data, boolean showNotification) 

    Bundle bundle = new Bundle();
    int notifyID = 1;
    for (String key : data.keySet()) 
        bundle.putString(key, data.get(key));
    
    if (showNotification) 
        Intent intent = new Intent(this, OnNotificationOpenReceiver.class);
        intent.putExtras(bundle);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, id.hashCode(), intent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
         NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setContentTitle(title)
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri);
         int numMessages = 0;
    //This line gives me error:error: cannot find symbol

    notificationBuilder.setContentText(currentText).setNumber(++numMessages);
        notificationManager.notify(notifyID, notificationBuilder.build());
     else 
        bundle.putBoolean("tap", false);
        FirebasePlugin.sendNotification(bundle);
    

【参考方案1】：

看起来 setContextText 方法中使用的 currentText 没有在代码中的任何地方实例化。
