找这样一个手机给我看看（这意味着手机不支持TextField,Command,Form...,那它还可以说自己支持j2me吗？）  我手机玩Gameloft的游戏 经常摇杆的下 键不能使.

对不起，这里不负责修理手机

   是键位不对. 不是我手机坏了

	public void commandAction(Command cmd, Item item) {
		if(item == uiMenuKey){
			GetKey keyCanvas = new GetKey((TextField)item);
			keyCanvas.show(controler.getDisplay());
		}
	}
