如何在android应用中添加location类？

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

boolean isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
boolean isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
        // 当位置变化时执行的代码
    }

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

    public void onProviderEnabled(String provider) {}

    public void onProviderDisabled(String provider) {}
};

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

locationManager.removeUpdates(locationListener);
