android gps当前位置

概述我想显示我当前的位置,但它显示了我在命令行上设置的纬度和经度！如果我没有在命令行上设置参数,它会显示 Eclipse中包含的纬度和经度！ 有没有人对此有所了解？我正在测试AVD. 我做了一个测试,看看我的位置是否已启用,但事实并非如此.我不确定为什么会这样. 这是我的代码： package com.manita.mapuse;import java.io.InputStream;impo 我想显示我当前的位置,但它显示了我在命令行上设置的纬度和经度！如果我没有在命令行上设置参数,它会显示 Eclipse中包含的纬度和经度！

有没有人对此有所了解？我正在测试AVD.

我做了一个测试,看看我的位置是否已启用,但事实并非如此.我不确定为什么会这样.

解决方法 除非您的PC / Mac具有GPS,否则AVD无法检测您的位置.使用真实设备或手动输入值来测试程序. 总结
