定位地图瓦片图TileOverlay TileOverlay是瓦片图层的相关类。瓦片图层是显示在基本地图上的一组图像。这些瓦片可以是透明的，允许您增加一些新的功能到现有的地图上。瓦片图层具有以下属性：

瓦片提供者：

提供者提供在瓦片图层上使用的图像。您必须在瓦片添加到地图上之前指定提供者。一旦瓦片添加到地图之后，提供者将不能更改。如果瓦片提供者发生变化，您必须使用 TileOverlay.clearTileCache() 方法确保以前的瓦片图不再出现。

Z轴值：

Z轴是控制瓦片图层重复区域的绘制顺序的值。Z轴较大的瓦片图层会在绘制在Z轴较小的瓦片图层上面。如果两个瓦片图层的Z轴数值相同，则覆盖情况将随机出现。

可见性：

瓦片图层是否可见，只是表示是否画在地图上。设置不可见的瓦片图层，将不被画在地图上，但会保留它的其他属性。默认瓦片图层是可见的。

调用这个类的方法必须在主线程使用，操作失败将会抛出IllegalStateException异常。

Positioning map tile TileOverlay TileOverlay is the related class of tile layers. Tile layers are a set of images displayed on the base map. These tiles can be transparent, allowing you to add some new features to the existing map. Tile layers have the following attributes:

Tile provider:

The provider provides the images used on the tile layer. You must specify the provider before adding the tiles to the map. Once the tiles are added to the map, the provider cannot be changed. If the tile provider changes, you must use the TileOverlay.clearTileCache() method to ensure that the previous tile images no longer appear.

Z-axis value:

The Z-axis is the value that controls the drawing order of the overlapping areas of the tile layers. Tile layers with a larger Z-axis will be drawn above those with a smaller Z-axis. If two tile layers have the same Z-axis value, the overlap will occur randomly.

Visibility:

Whether the tile layer is visible only indicates whether it is drawn on the map. Setting an invisible tile layer will not be drawn on the map, but its other attributes will be retained. By default, tile layers are visible.

Methods of this class must be called on the main thread, and failure to do so will throw an IllegalStateException exception.
