高德地图自动导航，定位功能

第一步 AndroidManifest 配置

    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <!--用于进行网络定位-->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
    <!--用于访问GPS定位-->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    <!--用于获取运营商信息，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"></uses-permission>
    <!--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"></uses-permission>
    <!--用于获取wifi的获取权限，wifi信息会用来进行网络定位-->
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
    <!--用于访问网络，网络定位需要上网-->
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <!--用于读取手机当前的状态-->
    <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
    <!--用于写入缓存数据到扩展存储卡-->

    <!--用于申请调用A-GPS模块-->
    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"></uses-permission>
    <!--用于申请获取蓝牙信息进行室内定位-->
    <uses-permission android:name="android.permission.BLUETOOTH"></uses-permission>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"></uses-permission>

<service android:name="com.amap.api.location.APSService"></service>
        <meta-data android:name="com.amap.api.v2.apikey" android:value="自己的高德Key">

        </meta-data>
        <activity android:name="com.amap.api.navi.AmapRouteActivity"
                  android:theme="@android:style/Theme.NoTitleBar"
                  android:configChanges="orientation|keyboardHidden|screenSize" />

导入依赖

    compile 'com.amap.api:navi-3dmap:latest.integration'
    compile 'com.amap.api:location:latest.integration'
    compile 'com.google.code.gson:gson:2.2.4'

创建MapUtils类。传入Context;

定位功能方法    getAddress()

导航功能   startNavigation()；

加载地图 setMap();

加载地图并且显示出对应位置的覆盖物 setMap();

覆盖物的点击事件 在Activity中调用。

aMap.setOnMarkerClickListener(new AMap.OnMarkerClickListener() {
            @Override
            public boolean onMarkerClick(Marker marker) {
                
                return true;
            }
        });

参数列表如果不懂 就直接crtl+方法名 查看方法注释。

获取APP的SHAI码 当SHAI码错误为7时 调用getSHAICode()方法 查看log日志 复制SHAI码，保存到高德的key中即可。

把以下的代码复制到MapUtils中

注意！！！

请把这个类中第一个成员变量KEY 修改为自己的高德Web端KEY

是WebKey 如果没有请创建一个

看下面这张图片

添加新的key 选择WEB服务即可
