ChoiceGroup的问题

摘要: ChoiceGroup的问题

为什么我这样定义会出问题？》：
ChoiceGroup cg = new ChoiceGroup("select:", ChoiceGroup.IMPLICIT);
而我这样定义是OK的。。
ChoiceGroup cg = new ChoiceGroup("select:", ChoiceGroup.EXCLUSIVE);
别的类别都不会出问题。就是IMPLICIT就出问题。报错如下：
Running with storage root DefaultColorPhone

IMPLICIT只适用于List

The IMPLICIT type is not valid for ChoiceGroup objects.

没有仔细看。呵呵。谢谢楼上的大哥
