例子演示如何将客户端数据存储在地形对象中。例子使用了 ICreator701 (CreateHoleOnTerrain), IGeometryCreator (CreateGeometryFromWKT), ITerrainHole701 (Position, set_ClientData, get_ClientData), INavigate701 (FlyTo) 的属性和方法。
private void ClientData() {
UI.runOnRenderThread(new Runnable() {
@Override
public void run() {
try {
// create hole on terrain
ITerrainHole hole = ISGWorld.getInstance().getCreator().CreateHoleOnTerrain(ISGWorld.getInstance().getCreator().getGeometryCreator().CreateGeometryFromWKT("POLYGON((6 6,11 6,11 11,6 11,6 6))"), "", "Hole on terrain");
hole.getPosition().setDistance(8000000); // store client data with key "My Data" in the hole
hole.set_ClientData("MyData", "Big hole"); // fly to the hole
ISGWorld.getInstance().getNavigate().FlyTo(hole);
Log.e("Tag", "Created hole on terrain and saved client data(Big Hole) in it. Click ok to read client data from it");
// read client data with key "My Data" from the hole
final String data = hole.get_ClientData("MyData");
Log.e("Tag","data is:"+data);
} catch (Exception e) {
}
}
});
}
tip : ITerraExplorerMessage调用set_ClientData会报错
