谷歌地图的当前位置标记和准确性半径覆盖 [英] Google Maps current location marker and accuracy radius overlay

问题描述

我怎么能显示在谷歌地图Android的API V2闪烁省略号和一个圆演示用户的当前位置，准确度（蓝色叠加）？

How can I display a blinking ellipsis and a circle demonstrating user's current location and the accuracy (blue overlay) on Google Maps Android API v2?

要更具体地讲，我怎么能有一个动画绘制像一个谷歌使用？我怎么能显示一个圆圈为蓝色覆盖（25％字母或类似的东西）？

To be more specifically, how can I have an animated drawable like the one Google uses? And how can I display a circle as a blue overlay (25% alpha or something like)?

感谢。

推荐答案

其实，解决的办法是比我想象的简单。

Actually, the solution is simpler than I thought.

在使用谷歌地图Android的API V2，该GoogleMap的对象有一个名为setMyLocation方法。如果设置为true，则地图API的我的定位布局将被激活，它会显示这个蓝色的省略号或箭头指示的方位。

When using Google Maps Android API v2, the GoogleMap object has a method called setMyLocation. If you set it to true, the my-location layout of the Maps API will be activated and it will display this blue ellipsis or an arrow indicating the bearing.
