但我有问题。 ..
当我安装应用程序那个时间给出正确的位置纬度和经度，但当我
去Onther城并运行已安装的应用程序那时它给我以前的位置，表示最后一个位置纬度和经度。当位置更改时，导入我的位置未更新。
请告诉我如何更新位置，或刷新上一个已知位置？
But I have Problem...
When I Install Application That Time give correct Location Latitude and Longitude,But when I
go to Onther city and run installed Application that time it give me previous Location ,mean Last Known Location latitude and Longitude.Insort my Location is Not Updated when Location Change.
please Tell me how update Location,or refresh last known location?
推荐答案
@Override
public void onLocationChanged(Location loc) {
}
什么它做到了吗？没有。那不是你应该对LocationChanged事件做出反应的那一行吗？
What does it do? Nothing. Isn't that the line where you ought to react on the LocationChanged event?
