= DefaultTreeNode("Root") 78 | tree_view.root = root 79 | val child1 = DefaultTreeNode("Child1") 80 | val child2 = DefaultTreeNode("Child2") 81 | //在你创建节点之后，你需要立即添加她 82 | root.addChild(child1) 83 | root.addChild(child2) 84 | val child3 = DefaultTreeNode("Child3") 85 | child1.addChild(child3) 86 | //是否默认显示根节点的孩子 87 | tree_view.isRootVisible = true 88 | //默认的动画 89 | tree_view.isDefaultAnimation = true 90 | ``` 91 | 92 | 3. 设置监听器 93 | 94 | `Tree2View` 有默认的点击监听器，你也可以自己实现，可以参考[这里](https://github.com/LeeReindeer/Tree2View/blob/master/app/src/main/java/xyz/leezoom/tree2/activity/MainActivity.kt#L111)。 95 | 96 | 选择（长按）监听器需要自己实现。 97 | 98 | 4. 自定义使用 99 | 100 | 只需要实现 `TreeAapater` ,就那么简单。 101 | 102 | ```java 103 | public class FileTreeAdapter extends TreeAdapter { 104 | //resourceId 是 itemView 的 xml 视图。 105 | public FileTreeAdapter(Context context, DefaultTreeNode root, int resourceId) { 106 | super(context, root, resourceId); 107 | } 108 | 109 | @Override 110 | public View getView(int position, View convertView, ViewGroup parent) { 111 | //your code here 112 | //... 113 | //调用 setPadding 来设置缩进 114 | setPadding(holder.arrowIcon, depth, -1); 115 | //根据数据改变 view 的状态（比如图标什么的） 116 | toggle(node, holder); 117 | } 118 | 119 | @Override 120 | public void toggle(Object... objects) { 121 | //需要自己实现 122 | } 123 | } 124 | ``` 125 | 126 | 之后只要设置一下适配器： 127 | 128 | ```kotlin 129 | val adapter = FileTreeAdapter(this@MainActivity, root, R.layout.layout_file_tree_item) 130 | treeView.treeAdapter = adapter 131 | ``` 132 | 133 | ## License 134 | 135 | Apache 2.0 -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # Tree2View 2 | 3 | 4 | 5 | [![](https://jitpack.io/v/LeeReindeer/Tree2View.svg)](https://jitpack.io/#LeeReindeer/Tree2View) 6 | 7 | > TreeView implementation in Android.Now available on Jitpack:tada: 8 | 9 | [中文版](/README-ZH.md) 10 | 11 | ## Features 12 | 13 | |TreeView|File Explorer(Advanced Example)| 14 | |--------|----------| 15 | |①Multi-level tree view | Basic file manager layout| 16 | |②Remember expansion state | Automatically expand the last unclosed directory| 17 | |③Customize TreeAdapter | Different types of documents show different Icon | 18 | |④Dynamic add and delete nodes | refresh status after delete and add files | 19 | |⑤Select listener | Long press node for file operations (Copy, Cut, Rename, Delete) | 20 | |⑥Animation support | Add or delete files with animation | 21 | 22 | You can also see [a more simple example](https://github.com/LeeReindeer/Tree2View-demo). 23 | 24 | ## Implement 25 | 26 | - TreeView extends from ListView. 27 | 28 | - DFS travel the expandable tree node, and convert it to List which adapt with [TreeAdapter](https://github.com/LeeReindeer/Tree2View/blob/master/treeview/src/main/java/xyz/leezoom/view/treeview/adapter/TreeAdapter.java). 29 | 30 | - Use [SimpleTreeAdapter](https://github.com/LeeReindeer/Tree2View/blob/master/treeview/src/main/java/xyz/leezoom/view/treeview/adapter/SimpleTreeAdapter.java) ot set different indentation on nodes of different depths. 31 | 32 | - Use LinkedList to store node's children, see [DefaultTreeNode](https://github.com/LeeReindeer/Tree2View/blob/master/treeview/src/main/java/xyz/leezoom/view/treeview/module/DefaultTreeNode.java). 33 | 34 | ## Preview 35 | 36 | ![](https://github.com/LeeReindeer/Tree2View/blob/master/screenshot/tree2view_demo1.png) 37 | 38 | ![](https://github.com/LeeReindeer/Tree2View/blob/master/screenshot/tree2view_demo2.png) 39 | 40 | ## Download 41 | 42 | 1. Add it in your root build.gradle at the end of repositories: 43 | 44 | ``` 45 | allprojects { 46 | repositories { 47 | ... 48 | maven { url 'https://jitpack.io' } 49 | } 50 | } 51 | ``` 52 | 53 | 2. Add the dependency 54 | 55 | ``` 56 | dependencies { 57 | implementation 'com.github.LeeReindeer:Tree2View:v0.1.2' 58 | } 59 | ``` 60 | 61 | ## Usage 62 | 63 | 1. Add in your xml: 64 | 65 | Feel free to use it as `ListView`. 66 | 67 | ```xml 68 | 75 | 76 | 77 | ``` 78 | 79 | 2. Add children in Kotlin code(Java is similar whit it) 80 | ```kotlin 81 | var root :DefaultTreeNode? = DefaultTreeNode("Root") 82 | tree_view.root = root 83 | val child1 = DefaultTreeNode("Child1") 84 | val child2 = DefaultTreeNode("Child2") 85 | // After create a node your should immediately add it. 86 | root.addChild(child1) 87 | root.addChild(child2) 88 | val child3 = DefaultTreeNode("Child3") 89 | child1.addChild(child3) 90 | //whether the root's children is expanded by default 91 | tree_view.isRootVisible = true 92 | //animation 93 | tree_view.isDefaultAnimation = true 94 | ``` 95 | 3. Add click listener and select listener 96 | 97 | Tree2View has a default click listener, but it's ok to add your own.You can refer to [here](https://github.com/LeeReindeer/Tree2View/blob/master/app/src/main/java/xyz/leezoom/tree2/activity/MainActivity.kt#L111). 98 | 99 | 4. If you want to use customized item view, you should implement `TreeAapater`, like this: 100 | ```java 101 | public class FileTreeAdapter extends TreeAdapter { 102 | //resourceId is your customized view resourceId, please use RelativeLayout, and let view neighbour. 103 | public FileTreeAdapter(Context context, DefaultTreeNode root, int resourceId) { 104 | super(context, root, resourceId); 105 | } 106 | 107 | @Override 108 | public View getView(int position, View convertView, ViewGroup parent) { 109 | //your code here 110 | //... 111 | //call padding for a better UI 112 | setPadding(holder.arrowIcon, depth, -1); 113 | //toggle your view's status here 114 | toggle(node, holder); 115 | } 116 | 117 | @Override 118 | public void toggle(Object... objects) { 119 | } 120 | ``` 121 | 122 | Then simply add: 123 | 124 | ```kotlin 125 | val adapter = FileTreeAdapter(this@MainActivity, root, R.layout.layout_file_tree_item) 126 | treeView.treeAdapter = adapter 127 | ``` 128 |
