ANDROID locationManager.requestLocationUpdates无法解析？

Question

我不明白为什么无法解析locationManager.requestLocationUpdates。我搜索了答案，它说您必须导入不再使用的 LocationClient。

这是我如何找到我当前的定位方法。如果我遗漏了什么，请告诉我。

 private void setUpMap() {
    // Enable MyLocation Layer of Google Map
    mMap.setMyLocationEnabled(true);

    // Get LocationManager object from System Service LOCATION_SERVICE
    LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    // Create a criteria object to retrieve provider
    Criteria criteria = new Criteria();
    // Get the name of the best provider
    String provider = locationManager.getBestProvider(criteria,true);



    LocationListener locationChangeListener = new LocationListener() {
        public void onLocationChanged(Location l) {
            if (l != null) {
                Log.i("SuperMap", "Location changed : Lat: " + l.getLatitude() + " Lng: " +
                        l.getLongitude());
            }
        }

        public void onProviderEnabled(String p) {
        }

        public void onProviderDisabled(String p) {
        }

        public void onStatusChanged(String p, int status, Bundle extras) {
        }

    };
    locationManager.requestLocationUpdates(provider,0,0,locationChangeListener);



    // Get Current Location
    Location myLocation = locationManager.getLastKnownLocation(provider);

    // set map type
    mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);

    // Get latitude of the current location
    double latitude = myLocation.getLatitude();
    // Get longitude of the current location
    double longitude = myLocation.getLongitude();

    // Create a LatLng object for the current location
    LatLng latLng = new LatLng(latitude, longitude);

    // Show the current location in Google Map
    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));

    // Zoom in the Google Map
    mMap.animateCamera(CameraUpdateFactory.zoomTo(14));
    mMap.addMarker(new MarkerOptions().position(new LatLng(latitude, longitude)).title("You are here!").snippet("Consider yourself located"));
}

这是我的进口

Answer 1

从 android.location 包中导入 LocationListener 接口(interface)，因为当前您正在从 com.google.android.gms.location 包中导入，但是 requestLocationUpdates 方法将 android.location.LocationListener 作为最后一个参数。

改变:

import com.google.android.gms.location.LocationListener;

到

import android.location.LocationListener;
