LocationListener如何在调用onLocationChanged（）时停止？

Question

我希望locationlistener在更改位置时停止使用gps，这可能吗？

Answer 1

public class MyActivity extends AppCompatActivity implements LocationListener {

    private LocationManager locationManager;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
    }

    @Override
    public void onLocationChanged(Location location) {
        locationManager.removeUpdates(this);
    }

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

    }

    @Override
    public void onProviderEnabled(String provider) {

    }

    @Override
    public void onProviderDisabled(String provider) {

    }

}

此处此是对LocationListener接口的引用。

如果您只想要单个位置更新，那么您可以致电

locationManager.requestSingleUpdate（LocationManager.GPS_PROVIDER，this，Looper.getMainLooper（））;
