废话不多说，首先去高德地图的API上获取key(这一步很重要)，因为没有KEY是无法获取高德地图的。
首先这是高德地图API的网址/，可以点击进去获取自己的key.这个流程在高德API上都是有教程的。在AndroidManifest.xml中获取定位为权限<!--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>
在Layout中设置xml文件
<com.amap.api.maps.MapViewandroid:id="@+id/mapView"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_marginTop="40dp"app:layout_constraintTop_toBottomOf="@id/offlineMap"tools:ignore="MissingConstraints"tools:layout_editor_absoluteX="31dp"></com.amap.api.maps.MapView>
直接上我的代码然后注释给的很清楚

上面的代码中直接复制就行，泛红的方法删除就可以是用了。
其实高德地图定位有三种模式：基站定位、Wi-Fi定位、GPS定位。其中基站，精度在500米-5000米之间、Wi-Fi定位精度较高，在5米－200米之间、GPS精度较高，在10米－100米左右。所以记录运动轨迹是一般会把基站定位和Wi-Fi定位的点过滤掉，这样就很少飘点。
写的不好请指教。
