廣播接收器的onReceive（）被調用以接收所有的接近警報。我究竟做錯了什麼？

Question

我是一個android新手，學習android，我正在開發一個簡單的Geofencing應用程序。 當我插入單個GeoFence時，一切正常。但是，當我使用2個以上的地理柵欄時，所有柵欄的onReceive都會被觸發，並且所有地理柵欄的通知都會在另一個上面創建。我試圖搜索網頁，並沒有提出任何解決方案。任何人都可以幫我解決我在做什麼錯了嗎？ 並且非常感謝。 :)

這裏是我寫爲服務類的代碼：

package com.example.multigeofence; 

import java.io.BufferedReader; 
import java.io.FileInputStream; 
import java.io.FileNotFoundException; 
import java.io.IOException; 
import java.io.InputStreamReader; 

import android.annotation.SuppressLint; 
import android.app.PendingIntent; 
import android.app.Service; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.content.IntentFilter; 
import android.database.sqlite.SQLiteDatabase; 
import android.location.Location; 
import android.location.LocationListener; 
import android.location.LocationManager; 
import android.os.Bundle; 
import android.os.IBinder; 

public class GeoFenceService extends Service { 

    LocationManager lm; 
    BroadcastReceiver br; 
    SQLiteDatabase myDatabase; 
    BufferedReader bur; 

    @Override 
    public IBinder onBind(Intent intent) { 
     return null; 
    } 

    @SuppressLint("SdCardPath") 
    @Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 

     lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
     lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 1, 
       new MyLocationListener()); 


     addProximityAlert(12.955299,77.679977,"Tata Elxsi",50); 
     addProximityAlert(12.187497,76.852970,"Mall",50); 
     addProximityAlert(12.552929,77.079977,"Dummy place",50); 

     return START_NOT_STICKY; 
    } 

    private void addProximityAlert(double latitude, double longitude, 
      String name, int rad) { 

     Intent intent = new Intent("idontknowyvusethis"); 
     PendingIntent proximityIntent = PendingIntent.getBroadcast(this, 0, 
       intent, 0); 

     lm.addProximityAlert(latitude, longitude, rad, -1, proximityIntent); 
     // will be used to generate an Intent to fire when entry to or exit from 
     // the alert region is detected 

     IntentFilter filter = new IntentFilter("idontknowyvusethis"); 
     registerReceiver(new proximityIntentReceiver(name, rad), filter); 

    } 

    public class MyLocationListener implements LocationListener { 
     public void onLocationChanged(Location location) { 
     } 

     public void onStatusChanged(String s, int i, Bundle b) { 
     } 

     public void onProviderDisabled(String s) { 
     } 

     public void onProviderEnabled(String s) { 
     } 
    } 

} 

下面是接收器類的代碼：

package com.example.multigeofence; 

import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.graphics.Color; 
import android.location.LocationManager; 
import android.util.Log; 
import android.widget.Toast; 

public class proximityIntentReceiver extends BroadcastReceiver { 
    private static final int NOTIFICATION_ID = 1000; 
    private String name; 
    private int rad; 

    public proximityIntentReceiver(String name, int rad) { 
     this.name = name; 
     this.rad = rad; 
    } 

    @SuppressWarnings("deprecation") 
    @Override 
    public void onReceive(Context context, Intent intent) { 
      String key = LocationManager.KEY_PROXIMITY_ENTERING; 
      String abc = ""; 

      Boolean entering = intent.getBooleanExtra(key, false); 

      if (entering) { 
       abc = "You are entering " + name + "! Beware!"; 
       Toast.makeText(context, "inside if : " + name, Toast.LENGTH_SHORT).show(); 
       Log.i("GeoGeo", "inside if : " + name); 
      } else 
       abc = "You are exiting " + name + "! Plz com bak :("; 

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

      Intent i = new Intent(); 
      PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, 
        i, 0); 

      Notification notification = createNotification(); 
      notification.setLatestEventInfo(context, abc, "The radius is: " 
        + rad, pendingIntent); 

      notificationManager.notify(NOTIFICATION_ID, notification); 
     } 


    private Notification createNotification() { 
     Notification notification = new Notification(); 

     notification.icon = R.drawable.ic_launcher; 
     notification.when = System.currentTimeMillis(); 

     notification.flags |= Notification.FLAG_AUTO_CANCEL; 
     notification.flags |= Notification.FLAG_SHOW_LIGHTS; 

     notification.defaults |= Notification.DEFAULT_VIBRATE; 
     notification.defaults |= Notification.DEFAULT_LIGHTS; 

     notification.ledARGB = Color.WHITE; 
     notification.ledOnMS = 1500; 
     notification.ledOffMS = 1500; 

     return notification; 
    } 
} 

這裏是清單：

任何提示或幫助將不勝感激。謝謝:)

你應該只註冊一個接收器而不是三個。要找出哪個位置觸發的通知，您應該添加一些數據到你的意圖傳遞給getBroadcast，這樣的事情：

Intent intent = new Intent("idontknowyvusethis"); 
intent.putExtra("fenceName", name); 
PendingIntent proximityIntent = PendingIntent.getBroadcast(this, 0, intent, 0); 

此意圖將在的onReceive退還給您：

String locationName = intent.getStringExtra("fenceName");
