站在巨人的肩膀上---重新自定义 android- ExpandableListView 收缩类,实现列表的可收缩扩展

距离上次更新,时隔略长,诸事繁琐,赶在去广州答辩之前,分享下安卓 android 中的一个 列表收缩 类---ExpandableListView

先上效果图:

如果想直接看实现此页面的代码请下滑到 红线 下

关于这个类的具体各函数的使用说明,这里不作详细说明,提供一个链接http://www.apkbus.com/android-124715-1-1.html,里面有关于此类的详细介绍。

我在这里主要通过源代码的注释和必要的说明,说明如何实现自定义的收缩列表。

必要的函数:

0->

1 ExpandableListView expandListView = (ExpandableListView) this.findViewById(R.id.ecpandable);
2 expandListView.setGroupIndicator(null);//去掉默认的下指箭头
3 expandListView.setDivider(null);//去掉下行线

 1->

1 @Override
2             public int getGroupCount() { 
3 //用于返回大标题的数目,例如我上面的图片,共有7个大标题
4                 return armTypes.length;
5 //armTypes 是用来存放大标题的数组,自定义
6             }

2->

1 @Override
2             public int getChildrenCount(int groupPosition) {
3 //用来返回一个大标题内的字标签数目,传入参数 groupPosition为当前
4 //大标题的下标,从0开始
5                 return arms_two[groupPosition].length;
6 //arms_two 是自定义的,存放子标签的 二维 数组
7             }
//对应上面,这个二维字符串数组共有 7 行,每行对应一个大标签
//每行的列数是子标签数,对应当前大标签,有多少个就是有多少个孩子
private String[][] arms_two = new String[][]{   //
                    {"班车列表(30分钟/班)","清记甜品","石头城","贝壳屋",}, //0~--
                    {"小a","清记甜品","石头城","贝壳屋",},
                    {"小c","清记甜品","石头城","贝壳屋","羊肉丁",},
                    {"小d",},
                    {"小e",},
                    {"小f",},
                    {"小aa",},
            };

3->

//返回当前的大标签数目,对应上面的 getGroupCount 函数,传入的是谁
// 返回的就是对应谁的数目,上面是armTypes,那么就是它的数目
@Override
            public long getGroupId(int groupPosition) {
                return groupPosition; //注意,它是从0下标开始的
            }

4->

//返回对应的每个大标签的 子标签数目,传入的 groupPosition 是当前的大
//标签下标,.length 就是当前行的列数
@Override
            public int getChildrenCount(int groupPosition) {
                return arms_two[groupPosition].length;
            }

5->

@Override
  public View getGroupView(int groupPosition, boolean isExpanded,View convertView, ViewGroup parent) {
   //返回大标签对应的 布局 视图,可以纯代码,也可以使用 xml 布局文件
  //使用 xml 布局文件例子
   RelativeLayout group = (RelativeLayout) RelativeLayout.inflate(getBaseContext(), R.layout.extend_group, null);
   return group;
}

 6->

@Override
   public View getChildView(int groupPosition, int childPosition, boolean isLastChild,View convertView, ViewGroup parent) {
  // 返回 子标签显示的 布局 视图,可以纯 代码,也可以 使用xml 布局文件
  //xml 布局例子
    LinearLayout child = (LinearLayout) LinearLayout.inflate(getBaseContext(), R.layout.extend_child, null);
  //建议使用listView
    return child;
}
