Android-可靠地获取当前位置

代码可能是这样的:

public class MyLocation {
    Timer timer1;
    LocationManager lm;

    public boolean getLocation(Context context)
    {
        lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
        lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListenerGps);
        timer1=new Timer();
        timer1.schedule(new GetLastLocation(), 20000);
        return true;
    }

    LocationListener locationListenerGps = new LocationListener() {
        public void onLocationChanged(Location location) {
            timer1.cancel();
            lm.removeUpdates(this);
            //use location as it is the latest value
        }
        public void onProviderDisabled(String provider) {}
        public void onProviderEnabled(String provider) {}
        public void onStatusChanged(String provider, int status, Bundle extras) {}
    };

    class GetLastLocation extends TimerTask {
        @Override
        public void run() {
             lm.removeUpdates(locationListenerGps);
             Location location=lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
             //use location as we have not received the new value from listener
        }
    }
}

编辑(asker):这是大多数答案,但我的最终解决方案使用了 Handler

如果用户的位置已经稳定,那么 getLastKnownLocation 将返回当前位置。我会打电话的 GetLastKnown位置 Location.getElapsedRealTimeNanos() 具有 SystemClock.elapsedRealTimeNanos() )如果修复程序太旧,则注册一个侦听器。
