等待当前位置 - GPS - Android Dev

Question

我必须等待才能获得当前位置，就像您在 Google 地图中并请求您的位置时一样。如果它无法获得任何位置，则通知错误并且什么也不做。

我在这里和网上阅读了答案，但都说我必须使用getLastKnownLocation 方法，但我不需要这个，我只需要当前位置。如果没有，我什么都不做。

从昨天开始阅读：GPS Android - get positioning only once

但是，您可以通过以下方式获取当前位置：

public class Example extends Activity implements LocationListener {
    LocationManager mLocationManager;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mLocationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);

        Location location = mLocationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        if(location != null && location.getTime() > Calendar.getInstance().getTimeInMillis() - 2 * 60 * 1000) {
            // Do something with the recent location fix 
            //  if it is less than two minutes old,
            //  otherwise wait for the update below
        }
    }

    public void onLocationChanged(Location location) {
        if (location != null) {
            Log.v("Location Changed", location.getLatitude() + " and " + location.getLongitude());
            // You need to call this whenever you are done:
            // mLocationManager.removeUpdates(this);
        }
    }

    // Required functions    
    public void onProviderDisabled(String arg0) {}
    public void onProviderEnabled(String arg0) {}
    public void onStatusChanged(String arg0, int arg1, Bundle arg2) {}
}
