百度地图——导航（地理编码输入地址获取经纬度）

最近自己在学习百度地图和讯飞语音，这里自己整理点导航方面的。我用的是Android studio 可能和eclipse有点不一样但大体差不多。

一.主要文件

1.如何获取密钥等步骤自行查询百度官网。。。这里贴需要的主要文件

2.lib包里面放着百度地图需要用的类

我个人不喜欢把jar包和so方法放一块，但是喜欢放一块的也行。要在bulid.gradle里面声明去哪找so方法

3.这里是需要的权限，我是Android5.0系统这个以上的系统要重写下权限获取

<!-- 连接网络权限，用于执行云端语音能力 -->
<uses-permission android:name="android.permission.INTERNET" />
<!-- 获取手机录音机使用权限，听写、识别、语义理解需要用到此权限 -->
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<!-- 这个权限用于进行网络定位 -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!-- 这个权限用于访问GPS定位 -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- 用于读取手机当前的状态 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!-- 写入扩展存储，向扩展卡写入数据，用于写入离线定位数据 -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!-- 用于访问wifi网络信息，wifi信息会用于进行网络定位 -->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!-- 获取运营商信息，用于支持提供运营商信息相关的接口 -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

4.百度地图的key和service

service必须要在jar包添加进去以后才有效不然都是报错（f就是包里面的一个类）

5.初始化

SDK的初始化一定要在setContentView之前！

二.java代码和布局代码

1.布局：

这个是导航的诱导界面，里面有个这里没有给图片报错删掉那一行就行了不影响功能
