想用定位和画面做一个围栏功能，超出这个区域会震动提醒。但是打开后底图会消失，Fence坐标系为WGS84，底图是天地图。
部分代码：
private boolean drawRegion(){
if(editLayer != null){
editLayer.setEditable(true);
mapView.getMapControl().setAction( Action.DRAWPLOYGON);
System.out.println("绘制结束1");
return true;
}
Workspace workspace = mapView.getMapControl().getMap().getWorkspace();
String datasourceName = "fence";
// 设计图层风格
GeoStyle geoStyle_R = new GeoStyle ();
geoStyle_R.setFillForeColor(new com.supermap.data.Color(220, 220,220));
geoStyle_R.setFillBackOpaque(true);
geoStyle_R.setFillOpaqueRate(40);
geoStyle_R.setLineWidth(0.1);
geoStyle_R.setLineColor(new com.supermap.data.Color(40,40,40));
LayerSettingVector layerSettingVector = new LayerSettingVector ();
layerSettingVector.setStyle(geoStyle_R);
if (mapView.getMapControl().getMap().getLayers().getCount() == 1) {
Datasource datasource = workspace.getDatasources().get(datasourceName);
Dataset dataset = datasource.getDatasets().get(0);
editLayer = mapView.getMapControl().getMap().getLayers().add(dataset, true);
} else {
editLayer = mapView.getMapControl().getMap().getLayers().get(0);
}
editLayer.setEditable(true);
editLayer.setAdditionalSetting(layerSettingVector);
mapView.getMapControl().setAction( Action.DRAWPLOYGON);
mapView.getMapControl().addGeometryAddedListener(mGeometryAddedListener);
return true;
}
private void initLocation(){

option.setOpenGps(true);//可选，默认false,设置是否使用gps
option.setLocationNotify(true);//可选，默认false，设置是否当gps有效时按照1S1次频率输出GPS结果
option.setIgnoreKillProcess(true);//可选，默认true，定位SDK内部是一个SERVICE，并放到了独立进程，设置是否在stop的时候杀死这个进程，默认不杀死
option.setEnableSimulateGps(false);//可选，默认false，设置是否需要过滤gps仿真结果，默认需要
option.setIsNeedLocationDescribe(true);//可选，默认false，设置是否需要位置语义化结果，可以在BDLocation.getLocationDescribe里得到，结果类似于“在北京天安门附近”
