这是我的尝试,但此方法仅在开始时调用,而不是在扩展状态更改时调用
谢谢你的想法 问题在于
if (convertView == null)
谢谢大家! 尝试在中的MainActivity中加载布局
<ExpandableListView Obj>.setOnGroupExpandListener();
.setOnGroupExpandListener();
及
.setOnGroupCollapseListener();
这两个布局都包含什么布局?您可以隐藏和显示“视图”,并更改线性布局的背景。或者将if-else条件置于if条件之外。会的work@SurenderKumar非常感谢。但是我会做更多的改变,但是这个;)这真的是最有用的方法吗?奥特赛德在哪里?
