Android LocationProvider不会更新

Question

我已将setInterval设置为10秒，并将setFastestInterval设置为1秒，但应用程序未更新地址位置。它只加载一次。

我希望它不止一次加载。我应该将mLocationProvider放入循环吗？

感谢您的帮助。

MainActivity：

public class MainActivity extends AppCompatActivity implements LocationProvider.LocationCallback {
    private LocationProvider mLocationProvider;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Find my location
        mLocationProvider = new LocationProvider(this, this);
    }


    public void handleNewLocation(Location location) {
        double currentLatitude = location.getLatitude();
        double currentLongitude = location.getLongitude();
        float currentAccuracy = location.getAccuracy();
    }
}

LocationProvider：

我读过https://developer.android.com/training/location/receive-location-updates，但它对我帮助不大。
