高德地图定位实现

GoogleMap不存在,SouGou占有率不高,BaiDu niao性差,所以肯定实现地图首选高德啦..

1.创建应用

官方文档地址: http://lbs.amap.com/api/android-location-sdk/guide/create-project/get-key

注册账号,创建对应的应用.
这里基本就是填资料啦,没什么难的地方,只不过创建应用之后设置key的时候,要获取SHA1,
我的获取方法:androidstudio3.0,利用Terminal工具:

根据签名文件分别获取debug和release的SHA1,直接贴主要命令行吧:

D:\A_Git3\XHBC>cd D:\JDK8\bin
D:\JDK8\bin>keytool -v -list -keystore C:\Users\zjp\.android\debug.keystore

2 Android Studio 配置工程

官方文档地址: http://lbs.amap.com/api/android-location-sdk/guide/create-project/android-studio-create-project

这里基本照着文档走就没问题,注意问题如下:
- 1. 此处,只是获取当前定位,比如获取当前位于哪个城市直接用定位就好,要显示地图就多下载一个2D,要添加复杂图层或者添加多个标记点等操作就要用到3D地图
- 2.2D地图不用下载.so库,3D地图要搭配.so库,主选arm架构的,笔记市场占有率在那摆着

3.获取定位数据

官方文档地址: http://lbs.amap.com/api/android-location-sdk/guide/android-location/getlocation

3.1 配置AndroidMainfest.xml文件

    <!-- 高德地图权限--><!--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--><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission><!--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><applicationandroid:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:theme="@style/AppTheme"><!--设置key--><meta-dataandroid:name="com.amap.api.v2.apikey"android:value="这里填写第一步你申请的那个key" /><!--声明定位service--><service android:name="com.amap.api.location.APSService"></service></application>

3.1 在布局文件中添加地图显示控件

此处注意2D和3D地图因为添加的jar包不同其MapView路径也是不同的,如下

2D:

<com.amap.api.maps2d.MapViewandroid:id="@+id/map"android:layout_width="fill_parent"android:layout_height="fill_parent" />

3D:

 <com.amap.api.maps.MapViewandroid:id="@+id/map"android:layout_width="match_parent"android:layout_height="match_parent" />

3.3 Activity里面进行注册配置

此处参考这篇博文,写的很详细了,如侵权请告知我立即删改,此处我在这个哥们写的基础上加上一点我自己的理解吧: https://www.jianshu.com/p/c3dc0cea0a2d
