我想创建多个接近警报,但我不能得到它的工作...broadcastReceiver可以捕捉多个广播吗?
我认为广播接收机被覆盖,因此只处理最后一个广播。所以,如果我有两个点,只有最后创建的意图创建一个最后会产生一个警报...
我读我应该使用请求代码,但我不知道如何做到这一点...
我设立挂起的意图和广播接收方法...
private void addProximityAlert(double latitude, double longitude, String poiName, String intentfilter) {
Bundle extras = new Bundle();
extras.putString("name", poiName);
Intent intent = new Intent(PROX_ALERT_INTENT+poiName);
intent.putExtras(extras);
PendingIntent proximityIntent = PendingIntent.getBroadcast(MainMenu.this, requestCode, intent, 0);
locationManager.addProximityAlert(
latitude, // the latitude of the central point of the alert region
longitude, // the longitude of the central point of the alert region
POINT_RADIUS, // the radius of the central point of the alert region, in meters
PROX_ALERT_EXPIRATION, // time for this proximity alert, in milliseconds, or -1 to indicate no expiration
proximityIntent // will be used to generate an Intent to fire when entry to or exit from the alert region is detected
);
requestCode++;
IntentFilter filter = new IntentFilter(intentfilter);
registerReceiver(new ProximityIntentReceiver(), filter);
}
我的广播接收器类
public class ProximityIntentReceiver extends BroadcastReceiver {
private static final int NOTIFICATION_ID = 1000;
@Override
public void onReceive(Context context, Intent intent) {
String key = LocationManager.KEY_PROXIMITY_ENTERING;
Boolean entering = intent.getBooleanExtra(key, false);
if (entering) {
Log.d(getClass().getSimpleName(), "entering");
}
else {
Log.d(getClass().getSimpleName(), "exiting");
}
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, null, 0);
Notification notification = createNotification();
notification.setLatestEventInfo(context,
"Proximity Alert!", "You are approaching: " +intent.getExtras().get("name"), pendingIntent);
//here-------------------------------------
notificationManager.notify(NOTIFICATION_ID, notification);
}
private Notification createNotification() {
Notification notification = new Notification();
notification.icon = R.drawable.androidmarker;
notification.when = System.currentTimeMillis();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.flags |= Notification.FLAG_INSISTENT;
notification.defaults |= Notification.DEFAULT_VIBRATE;
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.defaults |= Notification.DEFAULT_SOUND;
notification.ledARGB = Color.WHITE;
notification.ledOnMS = 300;
notification.ledOffMS = 1500;
return notification;
}
}
你能帮我吗?我真的坚持...
任何帮助将非常感谢!
只是为了让你们都知道我在我的原始代码上发布了更新其中包括GitHub上的完整示例:http://www.gauntface.co.uk/pages/blog/2010/12/28/how-to-multiple-proximity-alerts-in-android/ –
如何删除您的警报?我只是继续建设。 :( – deucalion0
它已经有一段时间了,我真的不记得我做了什么对不起。 – mixkat
