获取我的位置与setMyLocationEnabled（）方法 [英] Fetching my location with setMyLocationEnabled() method

问题描述

我试图使用 setMyLocationEnabled（）方法来获得地图中我的位置。有这种方法没有问题，我也用 setMyLocationButtonEnabled（）键，一切都很好。

I am trying to get my location in a map using the setMyLocationEnabled() method. There is no problem with this method, I have also used setMyLocationButtonEnabled() and everything is good.

但是，当我在地图上按一下按钮，我不明白的蓝点，表示我的位置。

But when I click on the button in the map, I don't get the "blue dot" that indicates my location.

你能告诉我这个问题可能是什么？

Can you tell me what the problem could be?

推荐答案

首先，您应该声明一个匿名内部类，实现 Google.OnMyLocationChangeListener ，或者你可以只是实现它在你的主类。比方说，你图的实例被称为地图。您必须设置监听器，像这样： map.setOnMyLocationChangeListener（本）。然后，你将不得不做这样的事情：

First, you should either declare an anonymous inner class, that implements Google.OnMyLocationChangeListener, or you could just implement it in your main class. Let's say the instance of your map is called map. You will have to set the listener, like this: map.setOnMyLocationChangeListener(this). Then, you will have to do something like this:

@Override
public void onMyLocationChange(Location location) //inherited from the interface you implemented
{
//do your thing, the variable "location" holds everything you need
}
