android ExpandableListView - 将某些组设置为不可扩展

Question

我有一个 ExpandableListView，我需要将某个组(groupPosition 已知且始终相同)设置为不可展开，并在点击。有没有办法做到这一点？

更新

我也只需要一次扩展一组，并尝试了以下方法(但这不能正常工作):

  getExpandableListView().setOnGroupClickListener(
            new OnGroupClickListener() {
                @Override
                public boolean onGroupClick(ExpandableListView parent,
                        View v, int groupPosition, long id) {
                    if (groupPosition == 1) {
                        Toast.makeText(getApplicationContext(), "TEST",
                                Toast.LENGTH_SHORT).show();
                    } else if (groupPosition != lastExpandedGroupPosition) {
                        getExpandableListView().collapseGroup(
                                lastExpandedGroupPosition);
                    } else
                        getExpandableListView().expandGroup(groupPosition);
                    lastExpandedGroupPosition = groupPosition;

                    return true;
                }
            });

这将起到作用 - 在 onGroupClick 中检查您想要专门处理的组，为它返回 true，为任何您想要由默认操作(展开/折叠)处理的组返回 false。

    mExpandableListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
        public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
            if(groupPosition == 2) {
                Toast.makeText(mContext, "Group 2 clicked", Toast.LENGTH_LONG).show();
                return true;
            } else
                return false;
        }
    });
