private static final String TAG = "MainActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {

//设置许可文件路径（默认路径“/SuperMap/license/”）
Environment.setLicensePath(rootPath + "/SuperMap/license/");
//组件功能必须在Environment初始化之后才能调用
Environment.initialization(getApplicationContext());
setContentView(R.layout.activity_main);
//打开工作空间
Workspace m_workspace = new Workspace();
WorkspaceConnectionInfo info = new WorkspaceConnectionInfo();
info.setServer(rootPath + "/SampleData/GeometryInfo/World.smwu");

m_workspace.open(info);
//将地图显示控件和工作空间关联
MapView m_mapView = findViewById(R.id.Map_view);

mapControl.getMap().setWorkspace(m_workspace);
// 打开工作空间中的第二幅地图
String mapName = m_workspace.getMaps().get(1);
mapControl.getMap().open(mapName);
mapControl.getMap().refresh();
}
