收到接近警报意图时如何接收位置信息？

发布于 2024-10-24 01:49:33 字数 174 浏览 3 评论 0原文

我需要使用 LocationManager 中的 addProximityAlert 方法添加多个接近警报。问题是，当我收到通知用户接近我正在侦听警报的区域之一的意图时，如果用户正在读取 KEY_PROXIMITY_ENTERING 的区域进入或退出，我可以获得，但我不知道该区域是什么他正在进入或退出。有什么办法可以获取此类信息吗？

好吧，要添加 ProximityAlert，您需要一个 PendingIntent，可以使用 PendingIntent.getBroadcast(aContext, aRequestCode, anIntent, 0); 获取 PeindingIntent；现在，在第三个参数“anIntent”中，您可以放置任何您想要的数据，例如位置对象，通过位置获取的城市名称，

我这样做：

private static final float DEFAULT_PROXIMITY = 1000f;
int requestCode = 0;
for (Location p : locationList) {
                Double _lat = p.getLatitude();
                Double _lon = p.getLongitude();
                float radious = DEFAULT_PROXIMITY;
                long expiration = -1;

                Intent intent = new Intent(PROXIMITY_ALERT_ACTION_FIRED);
                intent.putExtra( "location-lat" , p.getLatitude());
                intent.putExtra( "location-lon" , p.getLongitude());
                PendingIntent proximityIntent = PendingIntent.getBroadcast(this, requestCode, intent, 0);
                locationManager.addProximityAlert(_lat, _lon, radious, expiration, proximityIntent);
                requestCode++;
            }

现在，当您收到广播消息时，您必须获取位置来自传递的意图的信息，类似这样；

@Override
public void onReceive(Context context, Intent intent) {

  Boolean entering = intent.getBooleanExtra(key, false);
  if(entering){
    long lat = intent.getLongExtra("location-lat", -1);
    long lon = intent.getLongExtra("location-lon", -1);
    log.info("", "entering: " + lat + lon);
  }else{
    long lat = intent.getLongExtra("location-lat", -1);
    long lon = intent.getLongExtra("location-lon", -1);
    log.info("", "exiting: " + lat + lon);

  }
}

干杯

well, to add a ProximityAlert you need a PendingIntent, a PeindingIntent can be obtained with PendingIntent.getBroadcast(aContext, aRequestCode, anIntent, 0); Now, in the third parameter 'anIntent' you can put any data you want, like a Location object, a city name obtained with the location,

i do this like this:

private static final float DEFAULT_PROXIMITY = 1000f;
int requestCode = 0;
for (Location p : locationList) {
                Double _lat = p.getLatitude();
                Double _lon = p.getLongitude();
                float radious = DEFAULT_PROXIMITY;
                long expiration = -1;

                Intent intent = new Intent(PROXIMITY_ALERT_ACTION_FIRED);
                intent.putExtra( "location-lat" , p.getLatitude());
                intent.putExtra( "location-lon" , p.getLongitude());
                PendingIntent proximityIntent = PendingIntent.getBroadcast(this, requestCode, intent, 0);
                locationManager.addProximityAlert(_lat, _lon, radious, expiration, proximityIntent);
                requestCode++;
            }

now, when you receive the broadcast message, you must obtain the location info from the passed intent, something like this;

@Override
public void onReceive(Context context, Intent intent) {

  Boolean entering = intent.getBooleanExtra(key, false);
  if(entering){
    long lat = intent.getLongExtra("location-lat", -1);
    long lon = intent.getLongExtra("location-lon", -1);
    log.info("", "entering: " + lat + lon);
  }else{
    long lat = intent.getLongExtra("location-lat", -1);
    long lon = intent.getLongExtra("location-lon", -1);
    log.info("", "exiting: " + lat + lon);

  }
}

cheers
