Baidu Map

The app comes with a map soufun

1. Download the SDK of Baidu map familiarize yourself with the API Handbook Baidu Developer's account
2. 2.12 just have to have an AK to be able to build the application's package name and signature return the developer's serial number

Use Baidu Map steps

1. Application API Key
2. Create Project
3. Reference Library Armeabi only compatible with Arme CPU
   
4. Networking permissions
5. Initialize the map engine (2.13 is initialized in the code, the high version is configured in the manifest file)
6. referencing layouts

Mapview Show Map V

Inherit ViewGroup own definition control specifically for displaying maps

1. MapController    getController()   获取到地图的控制器 2.  让mapView的生命周期 必须和anctivity绑死在一起  onResume onPause destroy3.  setBuiltInZoomControls(boolean on)   设置是否启用内置的缩放控件回调 MKMapViewListener

Bmapmanager M

Ability to initialize the map engine

1. destroy()  当程序退出的时候调用2. start()  当程序可见的时候调用3. stop()  当程序不可见的时候调用 4. init(String strKey, MKGeneralListener listener) 方法校验key信息, 回调

Mapcontroller Map Controller C

Operations that specifically control the map

1. animateTo(GeoPoint point)   移动到指定位置2. setCenter(GeoPoint point)  在给定的中心点GeoPoint上设置地图视图。3. setZoom(float zoomLevel)  设置地图的缩放级别4.  缩放5.  旋转6.  改动鸟瞰角度

Layer

1. 卫星图层 mapView.setSatellite(true); 2. 交通图层 mapView.setTraffic(true);

Covering material
