推荐答案

您可以通过 setGroupIndicator 方式添加组指示灯。但默认情况下，指标的Andr​​oid拉伸高度以配合集团项目的高度。 （宽度可以通过 setIndicatorBounds 方式进行调整。） 因此，你应该让组指标的高度完全相同组项目的高度。 （见 ExpandableListView ）

You can add group indicator by setGroupIndicator method. But By default, Android stretch height of indicator to fit group item's height. (width can be adjusted by setIndicatorBounds method.) Therefore, you should make group indicator's height exactly same as group item's height. (see ExpandableListView)

否则，您可以完全自定义组指标是 onGroupCollapsed 和 onGroupExpanded 的方法。只要有一些国家的视图，当调用这些方法，改变你的看法的状态。 （见 ExpandableListAdapter ）

Otherwise, you can make fully customized group indicator with onGroupCollapsed and onGroupExpanded methods. Just make a view with some states and When these methods are called, change your view's state. (see ExpandableListAdapter)
