1 | # TreeAdapter [  ](https://bintray.com/plumcookingwine/maven/TreeRvAdapter/_latestVersion)
2 | 1、# 使用： compile ‘com.plumcookingwine.tree:TreeRvAdapter:1.0.3’
3 |
4 | 2、实体类的创建： TreeListDao是具体封装的对象， 里面有两个泛型，第一个就是父级对象，第二个就是子级集合； 其他属性为一些配置项：
5 | ```
6 | // 是否可展开收起
7 | private boolean isEnableExpand = true;
8 | // 默认是否展开状态
9 | private boolean isExpand = false;
10 | // 收起状态最少展示子item数量
11 | private int minCount = 6;
12 | ```
13 |
14 | 目前支持这几种配置；以后会逐渐完善。。。
15 |
16 | （举例）
17 |
18 |
19 | `
20 | data class FilterDao(
21 | var _ID: Int = 0,
22 | var mTitle: String = "",
23 | var mDesc: String = "",
24 | var mCheckOption: List?
25 | )
26 | `
27 | `
28 | data class OptionDao(
29 | var _ID: Int = 0,
30 | var mTitle: String = "",
31 | var mDesc: String = "",
32 | var isCheck: Boolean = false
33 | )
34 | `
35 |
36 |
37 | 其中FilterDao 是父级对象， OptionDao是子级对象，最后将这两个对象放到TreeListDao对象中:
38 |
39 | ```
40 | private fun initData(): MutableList> {
41 | val list = mutableListOf>()
42 | for (i in 0..5) {
43 | val dao = TreeListDao()
44 | val filterDao = FilterDao(i, "title$i", "title$i", null)
45 | val subs = mutableListOf()
46 | for (j in 0..20) {
47 | val subListDao = OptionDao(j, "o${j}t${i}", "o${j}t${i}", false)
48 | subs.add(subListDao)
49 | }
50 | dao.groupDao = filterDao
51 | dao.subList = subs if (i % 2 == 0) {
52 | dao.isMultiCheck = true } list.add(dao)
53 | }
54 | return list
55 | }
56 | ```
57 |
58 |
59 | 2、创建adapter继承自AbsTreeListAdapter，将TreeListDao传进来，重写方法：
60 | ```
61 | // 组item的layoutId
62 | public abstract int groupLayoutId();
63 | // 子item的layoutId
64 | public abstract int subLayoutId();
65 | // 绑定组item数据（K 为传进来的父对象泛型）
66 | public abstract void onBindGroupHolder(GroupItemViewHolder holder, K k, int groupIndex, int position);
67 | // 绑定子item数据（V 为传进来的子对象泛型）
68 | public abstract void onBindSubHolder(SubItemViewHolder holder, V v, int subIndex, int groupIndex, int position);
69 | ```
70 |
