《ArcGIS Runtime for Android 100.2.1学习笔记》二：通过WebTiledLayer加载天地图 1、WebTiledLayer WebTiledLayer是100.1后新加入的图层类型，用于定义一个可扩展的切片图层，该图层根据URL从切片服务器中请求图像，它提供了一种将非ArcGIS Services作为图层继承到地图中的简单方法。 URL通常遵循：http://{subDomain}.tile.opencyclemap.org/cycle/{level}/{col}/{row}... 阅读详情

1、上一节讲了如何加载天地图arcgis for android 入门与提高（五）加载天地图arcgis for android 入门与提高（五）加载天地图_郝大大的博客-优快云博客_android studio 天地图，这节讲解如何定位，定位有很多方式，但是原理都是基于GPS，第一种常用的定位方式就是Android系统自带的定位，封装在LocationListener和LocationManager里面，自带的有个很大的缺陷：室内基本无法定位！坐标系是WGS84的，误差在十米左右；第二种可以用百度定位API，对室内定位支持较好，但是它用的是百度坐标系；第三就是本章要讲的LocationDisplay，我们用的2000坐标系的底图，在上面可以轻松设置各种空间参考，也是封装好了，室内也能解算当前位置！

2、Android现在定位需要权限，用户允许定位才行，主要是ACCESS_FINE_LOCATION和ACCESS_COARSE_LOCATION 这两个权限：

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

3、请求权限

List<String> permissionList = new ArrayList<>();
if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.
        permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    permissionList.add(Manifest.permission.ACCESS_FINE_LOCATION);
}
if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.
        permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    permissionList.add(Manifest.permission.ACCESS_COARSE_LOCATION);
}

if (!permissionList.isEmpty()) {
    String[] permissions = permissionList.toArray(new String[permissionList.size()]);
    ActivityCompat.requestPermissions(MainActivity.this, permissions, 1);
}

4、定位有三种模式：

自动居中模式，可以用来初始化显示当前位置：

导航模式：

指北针模式：

5、完整代码：
