感應警報類不會觸發Android

我正在嘗試根據選定標記的位置設置接近警報，該標記的座標存儲在外部文件中，並讀入數組中，然後繪製數組該座標。感應警報類不會觸發Android

googleMap.setOnInfoWindowClickListener(
      new OnInfoWindowClickListener(){ 
    public void onInfoWindowClick(Marker marker) { 



     LatLng clickedMarkerLatLng = marker.getPosition(); 
       double lat = clickedMarkerLatLng.latitude; 
       double long1 = clickedMarkerLatLng.longitude; 

      Log.e("hello", "Output=" + lat + long1); 


    LocationManager lm; 
    // double lat=0; 
// double long1=0; //Defining Latitude & Longitude 
    float radius=3000; 


    lm=(LocationManager) getSystemService(LOCATION_SERVICE); 
    Intent i= new Intent("com.example.sleepertrain5.proximityalert");   //Custom Action 
    PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), -1, i, 0); 
    lm.addProximityAlert(lat, long1, radius, -1, pi); 
    Toast.makeText(getBaseContext(), 
      "Info Window [email protected]" + lat + "dddjdj" + long1, 
      Toast.LENGTH_SHORT).show(); 



    class ProximityReceiver extends android.content.BroadcastReceiver { 

    @Override 
    public void onReceive(Context arg0, Intent arg1) { 
     // TODO Auto-generated method stub 
     // The reciever gets the Context & the Intent that fired the broadcast as arg0 & agr1 

     String k=LocationManager.KEY_PROXIMITY_ENTERING; 
    // Key for determining whether user is leaving or entering 

     boolean state=arg1.getBooleanExtra(k, false); 
     //Gives whether the user is entering or leaving in boolean form 

     if(state){ 
     // Call the Notification Service or anything else that you would like to do here 
     Toast.makeText(arg0, "Welcome to my Area", 600).show(); 
     }else{ 
     //Other custom Notification 
     Toast.makeText(arg0, "Thank you for visiting my Area,come back again !!", 600).show(); 

     } 

    } 

    } 
      } 

}); 
}

所選標記的座標被傳遞給位置管理器，但接近報警不起作用。顯然此刻，它只是顯示敬酒，但它甚至沒有這樣做。根據日誌，Proximity接收器類永遠不會被調用，但我無法弄清楚爲什麼。我已經嘗試過使用不同尺寸的半徑，但它仍然不起作用。任何想法或幫助？

您需要向您的BroadcastReceiver註冊您用於PendingIntent的Intents操作。您可以在AndroidManifest.xml中通過添加以下幾行來執行此操作：

<receiver android:name="MyScheduleReceiver" > 
    <intent-filter> 
     <action android:name="com.example.sleepertrain5.proximityalert" /> 
    </intent-filter> 
</receiver>
