我要评论先上演示：
高德地图的key申请这里就不讲了，比较简单，网上有很多资料，或者前往官网查看：官方文档
依赖引入
项目使用了如下依赖：

implementation 'com.github.getactivity:xxpermissions:18.3'配置清单
<!--允许访问网络，必选权限-->
<uses-permission android:name="android.permission.internet" />
<!--允许获取粗略位置，若用gps实现定位小蓝点功能则必选-->
<uses-permission android:name="android.permission.access_coarse_location" />
<!--允许获取网络状态，用于网络定位，若无gps但仍需实现定位小蓝点功能则此权限必选-->

隐私合规
新版本在使用高德地图前都要调用隐私合规接口，不然无法使用
//隐私合规接口 mapsinitializer.updateprivacyshow(this,true,true); mapsinitializer.updateprivacyagree(this,true);
