Flex在地图上绘制TextSymbol标注

var gra:Graphic=new Graphic();
gra.geometry=graphicnew.geometry.extent.center;//获取地图中心
var content:String="标注XXX";
var tSymbol:TextSymbol = new TextSymbol(content);
tSymbol.textFormat = new TextFormat();
tSymbol.textFormat.size = 15;
tSymbol.textFormat.color = 0x000000;
tSymbol.border = false;
tSymbol.placement=InfoPlacement.BOTTOM;
tSymbol.yoffset=0;
tSymbol.xoffset=0;

gra.symbol=tSymbol;
