给用户的图形页面定义的注释 [英] give user defined annotation in mapview
本文介绍了给用户的图形页面定义的注释的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想探索在具有多个注释的图形页面我的城市，但我无法做到这一点。是任何一个建议我，我们怎么能与用户定义的经度和纬度的Android做到这一点。我创建了一个地图视图有一个注释但定义的系统，我必须从仿真器控制通过经度和纬度。我们如何发送与code与多个注释。

I want to explore my cities on a mapview with multiple annotations but I unable to do that. Is any one suggest me that how can we do this in android with user defined longitude and latitude. I created a map view with one annotation but with system defined, I have to pass longitude and latitude from emulator control. how we send that with code with multiple annotation.
Here is my code:
