我有4级元素的可扩展列表视图,当我点击最后一个要扩展的元素时,它根本不会展开,我甚至看不到一个项目,但它有更多的项目。
我尝试动态设置布局高度,但我不知道如何获得真正的子项目高度
提前致谢!

设置类似的侦听器:
int lastExpandedGroupPosition;
// Listview Group click listener
expListView.setOnGroupClickListener(new OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView parent, View v,
int groupPosition, long id) {
return false;
}
});
// Listview Group expanded listener
expListView.setOnGroupExpandListener(new OnGroupExpandListener() {
@Override
public void onGroupExpand(int groupPosition) {
if (groupPosition != lastExpandedGroupPosition) {
expListView.collapseGroup(lastExpandedGroupPosition);
}
lastExpandedGroupPosition = groupPosition;
}
});
// Listview Group collasped (Close) listener
expListView.setOnGroupCollapseListener(new OnGroupCollapseListener() {
@Override
public void onGroupCollapse(int groupPosition) {
}
});
// Listview on child click listener
expListView.setOnChildClickListener(new OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
switch (groupPosition) {
case 0:
switch (childPosition) {
case 0:
break;
default:
break;
}
break;
case 1:
switch (childPosition) {
case 0:
break;
default:
break;
}
break;
default:
break;
}
}
});
