--------------------------------------------------------------------------------
1 | 支持增删（递归删，普通删除）的折叠RecyclerView
2 |
3 | 
4 |
5 | 基于viewType实现，因此大量数据下不会有内存问题
6 |
7 | ## 数据结构：
8 |
9 | 1、数据存储的基本结构为树
10 |
11 | 2、在实际实现中树的保存方式分为了两种
12 |
13 | （1）、数据输入形式：基于父节点与子节点的树形二维结构存储
14 |
15 | （2）、数据与Adapter的联系形式：基于前序遍历的一维数组形式【ArrayList】
16 |
17 | ## 视图与数据联系
18 |
19 | 树的每一个层级对应Adapter的一种ViewType，对应一种实际的数据存储结构【Adapter的实际数据源】
20 |
21 |
22 | ## 功能类别
23 |
24 | - 折叠显示
25 |
26 | - 增：在指定节点增加子树【或单个节点】
27 |
28 | - 删：删除指定Item，删除操作分两种：
29 |
30 | 1、普通删除，仅删除单个节点
31 |
32 | 2、递归删除，当被删除节点的父节点不存在其他孩子节点时，删除父节点，以此向上递归删除
33 |
34 | ## 使用方法
35 | ### 新增依赖
36 | 1. 在项目的根目录gradle新增仓库如下：
37 |
38 | ```java
39 | allprojects {
40 | repositories {
41 | google()
42 | jcenter()
43 | maven { url 'https://jitpack.io' }
44 | }
45 | }
46 | ```
47 |
48 | 2. 使用module依赖，新增依赖：
49 |
50 | ```java
51 | compile 'com.github.liyuzero:extendedRecyclerView:1.1.0'
52 | ```
53 |
54 | ### 具体调用（详情见demo）
55 | 1. 构建原始数据，显示
56 |
57 | ```java
58 | ArrayList roots = new ArrayList<>();
59 | roots.add(new ExtendedNode<>(new Type1Bean(0), false));
60 |
61 | roots.add(new ExtendedNode<>(new Type1Bean(1), false));
62 | sons = roots.get(1).addSons(getType2Nodes(2)).getSons();
63 | sons.get(0).addSons(getType3Nodes(1));
64 | sons.get(1).addSons(getType3Nodes(2));
65 |
66 | roots.add(new ExtendedNode<>(new Type1Bean(2), true));
67 | sons = roots.get(2).addSons(getType2Nodes(3)).getSons();
68 | sons.get(1).addSons(getType3Nodes(3));
69 |
70 | roots.add(new ExtendedNode<>(new Type1Bean(3), true));
71 |
72 | final ExtendedRecyclerViewHelper extendedRecyclerViewHelper = = ExtendedRecyclerViewBuilder.build(recyclerView)
73 | .init(initList, new ExtendedHolderFactory() {
74 | @Override
75 | public ExtendedHolder getHolder(ExtendedRecyclerViewHelper helper, ViewGroup parent, int viewType) {
76 | switch (viewType){
77 | case 0:
78 | return new Type1Holder(helper, LayoutInflater.from(parent.getContext()).inflate(R.layout.holder1, parent, false));
79 | case 1:
80 | return new Type2Holder(helper, LayoutInflater.from(parent.getContext()).inflate(R.layout.holder2, parent, false));
81 | case 2:
82 | return new Type3Holder(helper, LayoutInflater.from(parent.getContext()).inflate(R.layout.holder3, parent, false));
83 | case 3:
84 | return new Type4Holder(helper, LayoutInflater.from(parent.getContext()).inflate(R.layout.holder4, parent, false));
85 | case 4:
86 | return new Type5Holder(helper, LayoutInflater.from(parent.getContext()).inflate(R.layout.holder5, parent, false));
87 | }
88 | return null;
89 | }
90 | }).complete();
91 |
92 | ```
93 |
94 | 2. 对每个Item进行操作
95 |
96 | ```java
97 | //增加节点
98 | ArrayList list = new ArrayList<>();
99 | list.add(new ExtendedNode(new Type2Bean(111), false, new ExtendedNode(new Type3Bean(1111))));
100 | list.add(new ExtendedNode(new Type2Bean(111)));
101 | extendedRecyclerViewHelper.insertItems(initList.get(0), 0, list);
102 |
103 | //删除节点
104 | helper.usuallyDelete(getLayoutPosition());
105 | //递归删除
106 | helper.recursionDelete(getLayoutPosition(), 1);
107 | ```
