接近警报类不会触发安卓

Question

我试图根据所选标记的位置设置接近警报，其坐标存储在外部文件中并读取到数组中，该数组反过来绘制坐标。

    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 clicked@" + 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();
      }
    }
    }
            }
});
}

所选标记的坐标被传递给位置管理器，但接近警报不起作用。显然现在，它只是显示一个祝酒词，但它甚至没有这样做。根据日志，接近接收器类从未被调用，但我不知道为什么。我试过不同大小的半径，它仍然不起作用。有什么想法或帮助吗?

你需要用PendingIntent的intent动作注册BroadcastReceiver。你可以在AndroidManifest.xml中添加这些行:

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