实现 微信/QQ聊天 发送位置功能

利用百度地图 实现QQ/微信发送位置功能

1.看到好多同学 项目需要 模仿发送位置 功能 自己项目也使用了 经过摸索现在分享出来

2.申请百度地图key(http://lbsyun.baidu.com/apiconsole/key);

3.主要界面代码 定位界面,内含 一个 popupWindow 里面显示的内容及 发送地图需要的内容 （图片+Location 点及 地点名字address）

/**
* 重要说明  1.本demo 利用百度地图模仿 实现 微信/QQ  聊天   发送位置功能
*       2. 考虑到具体界面比较复杂 所以并未 全仿界面 ，提供实现思路。
*       3. 拿到demo 后 请从bin 文件中 提取 已经编译好的APK  试看效果。
*       4. 更换menifast 里面  百度地图 的你自己的 key后  可在本地重新编译 运行
*       5.百度地图 key申请地址(http://lbsyun.baidu.com/apiconsole/key)
*       6.本demo  mPopupWindow 中显示的内容 即为 要显示在聊天窗口中的内容  包括一张实时 截图 及一个Location 点。
*       7.如有疑问 可联系QQ: 194093798 相互交流学习。
