我必须等待才能获得当前位置,就像您在Google地图中一样,它要求您的位置一样。如果它无法获取任何位置,请通知错误并且不执行任何操作。
我在这里和网络上阅读了答案,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 - 仅获得一次定位
但以下是获取当前位置的方法:
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) {}
}
