SuperMap iMobile for Android 地图添加POI兴趣点

作者：程溯

简介

Demo按类型往地图里添加POI兴趣点，并添加兴趣点的名称（name）与详细信息(detail)。地图上不同类型的POI兴趣点采用不同符号来表示。

示例数据

Data： mypoi.udb、mypoi.udd、mypoi.smwu

关键类型/成员

GeoStyle类

GeoPoint类

Environment类

WorkspaceConnectionInfo类

Map.setWorkspace()方法

MapControl.addGeometryAddedListener()方法

DatasetVector.query()方法

Recordset.edit()方法

Recordset.setGeometry()类

Recordset.setFieldValue()方法

Recordset.update()方法

使用步骤

(1) 将iMobile for android根目录的libs目录下的armeabi目录、com.supermap.data.jar、
com.supermap.mapping.jar拷贝至MyPoi工程目录的libs目录。
(2) elcipse导入MyPoi工程，如果需要，修改工程属性。
(3)需要将数据文件拷贝至android手机或模拟器的指定目录下。
(4) 编译运行程序，通过类型下拉列表选择POI类型，单击“添加”按钮，设置添加操作状态。
(5) 在地图上需要的位置单击，添加兴趣点，添加之后再单击“提交”按钮，提交操作。在弹出的页面中填写名称和详细信息，单击“添加”按钮返回地图页面，地图窗口中显示了POI的符号和名称。
