问题：1：仅定位后显示当前位置的图标如
，在此基础上添加动态图层以开发查询功能，结果是实时定位能实现，查询功能正常，仅上图位置图标不显示。
2:在单独实现定位功能时，手机转动上图标“圆”随之转动，三角形不动，如何改成三角形转动，而圆圈不动？
本人代码：
mMapControl.getMap().refresh();
mDynView = new DynamicView(context, mMapControl.getMap());
mView = new CompassView(this);
mapView.addDynamicView(mDynView);
mapView.addView(mView);
mGesture = new Gesture(mapView,mDynView);
mPopup = new QueryResultPopup(mapView,mDynView);
mMapControl.getMap().refresh();
mGesture.setSearchAroundListener(new SearchAroundListener() {
public void searchGeometry(Geometry geoRegion) {
query(geoRegion, DatasetType.POINT);
}
});
