ExpandableListView 的默认行为是在单击组的标题时折叠该组。不点击就能显示吗？始终向 child 展示而不点击

Answer 1

尝试使用此代码

ExpandableListView mExpandableListView = (ExpandableListView) findViewById(R.id.exListview);
int count = viewAdapter.getGroupCount();
for (int position = 1; i <= count; position++)
{
    mExpandableListView.expandGroup(position - 1);
}
