无法显示多层次扩展列表视图中至少节点 [英] Unable to show least node of multi level expandable list view

问题描述

我有4个级别的元素，当我最后一个元素上单击展开扩展列表视图，它不扩大可言，我无法看到，即使一个项目，但它有更多的项目。

I have expandable list view with 4 levels of elements, when I click on the last element to expand, it doesn't expand at all, I am not able to see even one item but it has more items.

我试图动态设置布局的高度，但我不知道如何获得真正的儿童身高的项目

I tried to set layout height dynamically, but i don't know how to get real children items height

在此先感谢！

推荐答案

设置监听器这样的：

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;
                }
            }
        });
