Android开源：TreeView－利用 RecyclerView 打造高性能树形控件

   <h2>TreeView</h2>    <p>An android tree view with high performance and rich functions</p>    <h3>Captures</h3>    <p>There are some gifs from Demo:</p>    <ul>     <li>Select node:</li>    </ul>    <p style="text-align:center"><img src="https://simg.open-open.com/show/6be9434c6ad1e0b3a89728ed2b382c12.gif"></p>    <ul>     <li>Operate all:</li>    </ul>    <p style="text-align:center"><img src="https://simg.open-open.com/show/8f8d3be75cfd7ed61644d72cc4c74e2d.gif"></p>    <h3>Features</h3>    <ul>     <li>expandAll/collapseAll</li>     <li>expandNode/collapseNode</li>     <li>expandLevel/collapseLevel</li>     <li>toggleNode</li>     <li>deleteNode/addNode</li>     <li>selectNode/deselectNode</li>     <li>selectAll/deselectAll</li>     <li>getAllSelectedNodes</li>    </ul>    <h3>Usage</h3>    <p>1.Reference the library from your module's build.gradle:</p>    <pre>  <code class="language-java">compile 'me.texy.treeview:treeview_lib:1.0.2'</code></pre>    <p>2.Implement your all level's BaseNodeViewBinder</p>    <p>Sample：</p>    <pre>  <code class="language-java">public class FirstLevelNodeViewBinder extends BaseNodeViewBinder {    TextView textView;    public FirstLevelNodeViewBinder(View itemView) {       super(itemView);        textView = (TextView) view.findViewById(R.id.node_name_view)    }        @Override    public int getLayoutId() {      return R.layout.item_first_level;    }        @Override    public void bindView(TreeNode treeNode) {      textView.setText(treeNode.getValue().toString());    }  }    SecondLevelNodeViewBinder  ThirdLevelNodeViewBinder  .  .  .</code></pre>    <p>If you want add the selectable feature,replace BaseNodeViewBinder with CheckableNodeViewBinder.</p>    <p>3.Implement the BaseNodeViewFactory</p>    <p>Sample：</p>    <pre>  <code class="language-java">public class MyNodeViewFactory extends BaseNodeViewFactory {    @Override    public BaseNodeViewBinder getNodeViewBinder(View view, int level) {      switch (level) {        case 0:          return new FirstLevelNodeViewBinder(view);        case 1:          return new SecondLevelNodeViewBinder(view);        case 2:          return new ThirdLevelNodeViewBinder(view);        default:          return null;      }    }  }</code></pre>    <p>If you do not want to create a class file,just implement a anonymous inner class in TreeView's constructor</p>    <p>4.Add TreeView to wherever you want</p>    <p>Sample:</p>    <pre>  <code class="language-java">TreeNode root = TreeNode.root();  //build the tree as you want  for (int i = 0; i < 5; i++) {    TreeNode treeNode = new TreeNode(new String("Child " + "No." + i));    treeNode.setLevel(0);    root.addChild(treeNode);  }  View treeView = new TreeView(root, context, new MyNodeViewFactory()).getView();  //add to view group where you want </code></pre>    <h3>License</h3>    <p>Copyright 2017 shineM.</p>    <pre>  <code class="language-java">Licensed under the Apache License, Version 2.0 (the "License");  you may not use this file except in compliance with the License.
