android studio高德地图的显示于定位（附带逆地理编码围栏）

首先注册高德成为开发者（打开高德地图，点击底部的开发者平台），创建应用，按照要求填写相应信息

网站：http://lbs.amap.com/api/android-sdk/guide/create-project/get-key

途中包含了发布版的SHA1安全码和测试版SHA1安全码，两者的值可以看

照做就一定会获取的。

这里我讲发布版和调试版都用的relase版本的sha1

之后再去下载相应的Jar包，这里我用的是

3D地图的jar包

注意：2D地图的jar包，与3D地图的jar包因为接口有一样的，导致冲突无法使用。

在jnilibs下放入一下文件

因为有些人的android studio无法显示，但又不报错（我就这样）。你就需要将以上红圈类容放入libs，才能显示

之后在

将导入的jar包添加到类包；

选择，找到于自己名字一样的Jar，添加就可以了。之后检查在build.gradle 是否添加了以下类容

compile files('libs/AMap3DMap_5.1.0_AMapSearch_5.1.0_AMapLocation_3.4.0_20170518.jar')
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'

并且设置jar包的位置为libs

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

在androidManifest.xml中添加自己的添加权限

<!-- 用于进行网络定位 -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <!-- 用于访问GPS定位 -->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <!-- 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" />
    <!-- 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" />
    <!-- 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" />
    <!-- 用于访问网络，网络定位需要上网 -->
    <uses-permission android:name="android.permission.INTERNET" />
    <!-- 用于读取手机当前的状态 -->
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <!-- 用于写入缓存数据到扩展存储卡 -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <!-- 用于申请调用A-GPS模块 -->
    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
    <!-- 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 android:name="android.permission.BLUETOOTH_ADMIN" />

　　添加自己的key

<meta-data
                android:name="com.amap.api.v2.apikey"
                android:value="你的key" />

　　添加定位方法

<service android:name="com.amap.api.location.APSService" />

　　

在Activity_main.xml中添加

<TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/text1"/>
<com.amap.api.maps.MapView
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:id="@+id/map">
        </com.amap.api.maps.MapView>

　　如果要使用那个逆地理的编码围栏，你需要自己设定button控件的响应事件，通过返回值来控制button是否开启
