唯一的解决办法就是重写TileList组件中drawSelectionIndicator 和drawHighlightIndicator 。
复制代码 代码如下:

* Description:
* 该组件实现选中和划过theme样式，并且添加间距

package myLib {
import flash.display.Graphics;
import flash.display.Sprite;
import mx.controls.TileList;
import mx.controls.listClasses.IListItemRenderer;
public class MyTileList extends TileList {
[Bindable]
private var _verticalGap:Number = 0;
[Bindable]
private var _horizontalGap:Number = 0;
public function MyTileList() {
super();
}
/**

* **/
override protected function drawHighlightIndicator(indicator:Sprite, x:Number, y:Number, width:Number, height:Number, color:uint, itemRenderer:IListItemRenderer):void {
//绘图
var g:Graphics = indicator.graphics;
g.clear();
g.beginFill(color);
//画椭圆
g.drawEllipse(0, 0, width - _horizontalGap, height - _verticalGap);
g.endFill();
indicator.x = x;
indicator.y = y;
}
/**

override protected function drawSelectionIndicator(indicator:Sprite, x:Number, y:Number, width:Number, height:Number, color:uint, itemRenderer:IListItemRenderer):void {

g.beginFill(color);
//画椭圆
g.drawEllipse(0, 0, width - _horizontalGap, height - _verticalGap);

indicator.x = x;
indicator.y = y;
}
//=============================
// set and get
//=============================
public function set verticalGap(value:Number):void {
_verticalGap = value;

public function get verticalGap():Number {
