我有一项服务需要运行onLocationChanged。当我尝试将onLocationChanged方法放在onStartCommand中时，它不起作用。如何在服务启动时将onLocationChanged设置为运行？
public class myService extends Service implements LocationListener {
Double lat;
Double lng;
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// Let it continue running until it is stopped.
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
return START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service Destroyed", Toast.LENGTH_LONG).show();
}
@Override
public void onLocationChanged(Location location) {
if (MainActivity.location != null) {
lat = MainActivity.location.getLatitude();
lng = MainActivity.location.getLongitude();
if (MainActivity.placeArrayList.size() != 0) {
for (int i = 0; i < MainActivity.placeArrayList.size(); i++) {
Log.e("hello", String.valueOf(Float.parseFloat(MainActivity.latitudeArrayList.get(i))));
MainActivity.destination.setLatitude(Double.parseDouble(MainActivity.latitudeArrayList.get(i)));
MainActivity.destination.setLongitude(Double.parseDouble(MainActivity.longitudeArrayList.get(i)));
Log.e("distancemeters", Stri ng.valueOf(MainActivity.location.distanceTo(MainActivity.destination)));
if (MainActivity.location.distanceTo(MainActivity.destination)<100) {
AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_RING, AudioManager.RINGER_MODE_SILENT, AudioManager.FLAG_SHOW_UI);
} else {
}
}
}
}
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
}
}
