[ArcGIS for android学习]com.esri.android.map下面有些什么

我觉得在应用程序里，有两个东西很重要，一个是装地图的容器com.esri.android.map.MapView，一个是被容器装的地图com.esri.android.map.Layer

com.esri.android.map.MapView的继承关系是extends android.view.ViewGroup

而com.esri.android.map.Layer则是extends java.lang.Object

com.esri.android.map.MapView

MapView通过

int	addLayer(Layer layer) Adds the child Layer.
int	addLayer(Layer layer, int index) Adds the child Layer at the given index.
void	%29]addLayers(Layer[] layerArray) Adds the Layer array.

Layer	getLayer(int index) Gets a layer at the given index.
Layer	getLayerByURL(String url) Gets a layer by its service URL.
Layer[]	getLayers() Returns all child Layers that are added to the MapView.

六个方法和Layer发生联系

com.esri.android.map.Layer

继承自Layer 的有DynamicLayer, GraphicsLayer, GroupLayer, TiledLayer
