我正在尝试使用FusedLocationApi获取当前位置

Question

我正在尝试使用融合位置API获取当前位置。

private void setInitialLocation() {


        if (ActivityCompat.checkSelfPermission(getActivity(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(MainActivity.this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }

        LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, request, new LocationListener(){
            @Override
            public void onLocationChanged(Location location) {


                mLastLocation = location;

                try {

                } catch (Exception ex) {

                    ex.printStackTrace();
                    Log.e("MapException", ex.getMessage());

                }

            }
        });
    }

android studio发出此错误

  

类'从LocationListener派生的Annonymous类'必须是   声明抽象或实现抽象方法。

当我实现位置监听器的所有抽象方法时。

FusedLocationApi已弃用。使用此FusedLocationProviderClient

详细链接为here

创建FusedLocationProviderClient

的实例

mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);


mFusedLocationClient.getLastLocation()
    .addOnSuccessListener(this, new OnSuccessListener<Location>() {
        @Override
        public void onSuccess(Location location) {
            // Got last known location. In some rare situations, this can be null.
            if (location != null) {
                // Logic to handle location object
            }
        }
    });
