简介：

 在做一个软件时，用到了定位功能。网上有很多关于google 的GPS定位，但网上关于google定位都没有用，

搜索下原因：（这里建议大家在中国就尽量不使用系统自带的定位）

   因为Google的服务器不在中国（就算能网上关于定位的代码能用，那也非常的慢，除非你的应用是在国外使用）
   由于网络等原因所以定位一般会失败

   于是转向使用百度api来定位。


所用到的百度API参考地址。

   取得位置的百度官方sdk参考 Android定位SDK

   由坐标获取地址方法参考 Geocoding API 的 7.逆地理编码


先讲解怎么使用百度api获取获取地理坐标


准备工作：

　　（1）第一步，下载定位Android locSDK3.3。
下载地址：http://developer.baidu.com/map/static/doc/locSDK3.3.zip

　　（2）第二步，解压缩Android locSDK3.3

　　准备工作至此已经结束。

一、工程配置

　　1、第一步，在工程里新建libs文件夹，将开发包里的locSDK_3.3.jar拷贝到libs根目录下，将liblocSDK3.so拷贝到libs\armeabi目录下，拷贝完成后的工程目录如下图所示；

　　２、第二步（第一步导入后可以使用就不用这一步了）：在工程属性->Java Build Path->Libraries中选择“Add External JARs”，选定locSDK_3.3.jar，确定后返回。

　　通过以上两步操作后，您就可以正常使用百度地图定位SDK为您提供的全部功能了。

在AndroidManifest.xml加入如下所示权限及server

< service
             android:name = "com.baidu.location.f"
             android:enabled = "true"
             android:permission = "android.permission.BAIDU_LOCATION_SERVICE"
             android:process = ":remote"  >
             < intent-filter >
                 < action  android:name = "com.baidu.location.service_v3.3"  />
             </ intent-filter >
         </ service >


由于Location.java继承自Application，所以需要在配置文件中<application android:name="com.baidulocation.MainActivity" ……>节中需要加android:name，其中com.genwoxue.baidulocation为我们的包名称，Location为继承Application的类名称。

　　<service android:name="com.baidu.location.f" android:enabled="true"   android:process=":remote"&gt;  </service>这个是来自百度定位中的服务，不可更改其中内容。 


我做好的如下所示

补充：安列参考

在http://blog.csdn.net/ryantang03/article/details/7951260博客中提到可以通过 Android定位SDK  直接获取地址，但是经过实验不行。或许我这地方并不有名的原因。



于是我使用  Android定位SDK 加 Geocoding API的模式来获取位置。


为了获取的地理坐标能在函数中被调用，我封装了定位函数

在官方的文档中关于官方说的返回的 json， 需要加个[] 再才能解析。于是直接封装了个直接有坐标获取地址的类。

获取坐标室外会有8秒左右的延迟，所以在获取地理名称时需要等待获取坐标完成后。在主main中，定义一个线程（这里不能再直接建个类来直接获取地名了，需要在Aactivity中实现）


我的工程如下布局，主要看activity中的线程如何实现获取位置的


activity_main.xml布局如下

在手机上运行能获取坐标(室外获取到地理名称8到10秒。室内时间更长或无法定位）（需链接网咯）
