3 | TreeView implement in Android with RecyclerView.. 4 | 5 | ## Effect 6 | ![](https://raw.githubusercontent.com/TellH/RecyclerTreeView/master/raw/effect.gif) 7 | 8 | ## Usage 9 | ### Setup 10 | root build.gradle 11 | ```groovy 12 | allprojects { 13 | repositories { 14 | jcenter() 15 | maven { url "https://jitpack.io" } 16 | } 17 | } 18 | ``` 19 | app build.gradle 20 | ```groovy 21 | dependencies { 22 | compile 'com.github.TellH:RecyclerTreeView:1.2.0' 23 | } 24 | ``` 25 | 26 | 27 | 28 | ### Quick Start 29 | 30 | - Create a Java bean class and implement the LayoutItemType, to attach item layout id to it. 31 | 32 | ```java 33 | public class Dir implements LayoutItemType { 34 | public String dirName; 35 | 36 | public Dir(String dirName) { 37 | this.dirName = dirName; 38 | } 39 | 40 | @Override 41 | public int getLayoutId() { 42 | return R.layout.item_dir; 43 | } 44 | } 45 | ``` 46 | 47 | 48 | 49 | - Create a ViewBinder to bind view with the data bean. As you see, `provideViewHolder(View itemView)` corresponds for `onCreateViewHolder` in RecyclerView, and `bindView` corresponds for `onBindViewHolder` in RecyclerView. 50 | 51 | ```java 52 | public class FileNodeBinder extends TreeViewBinder { 53 | @Override 54 | public ViewHolder provideViewHolder(View itemView) { 55 | return new ViewHolder(itemView); 56 | } 57 | 58 | @Override 59 | public void bindView(ViewHolder holder, int position, TreeNode node) { 60 | File fileNode = (File) node.getContent(); 61 | holder.tvName.setText(fileNode.fileName); 62 | } 63 | 64 | @Override 65 | public int getLayoutId() { 66 | return R.layout.item_file; 67 | } 68 | 69 | public class ViewHolder extends TreeViewBinder.ViewHolder { 70 | public TextView tvName; 71 | 72 | public ViewHolder(View rootView) { 73 | super(rootView); 74 | this.tvName = (TextView) rootView.findViewById(R.id.tv_name); 75 | } 76 | 77 | } 78 | } 79 | ``` 80 | 81 | 82 | 83 | - Add TreeNode to TreeViewAdapter. 84 | 85 | ```java 86 | List nodes = new ArrayList<>(); 87 | TreeNode app = new TreeNode<>(new Dir("app")); 88 | nodes.add(app); 89 | app.addChild( 90 | new TreeNode<>(new Dir("manifests")) 91 | .addChild(new TreeNode<>(new File("AndroidManifest.xml"))) 92 | ); 93 | app.addChild( 94 | new TreeNode<>(new Dir("java")).addChild( 95 | new TreeNode<>(new Dir("tellh")).addChild( 96 | new TreeNode<>(new Dir("com")).addChild( 97 | new TreeNode<>(new Dir("recyclertreeview")) 98 | .addChild(new TreeNode<>(new File("Dir"))) 99 | .addChild(new TreeNode<>(new File("DirectoryNodeBinder"))) 100 | .addChild(new TreeNode<>(new File("File"))) 101 | .addChild(new TreeNode<>(new File("FileNodeBinder"))) 102 | .addChild(new TreeNode<>(new File("TreeViewBinder"))) 103 | ) 104 | ) 105 | ) 106 | ); 107 | TreeNode res = new TreeNode<>(new Dir("res")); 108 | nodes.add(res); 109 | res.addChild( 110 | new TreeNode<>(new Dir("layout")) 111 | .addChild(new TreeNode<>(new File("activity_main.xml"))) 112 | .addChild(new TreeNode<>(new File("item_dir.xml"))) 113 | .addChild(new TreeNode<>(new File("item_file.xml"))) 114 | ); 115 | res.addChild( 116 | new TreeNode<>(new Dir("mipmap")) 117 | .addChild(new TreeNode<>(new File("ic_launcher.png"))) 118 | ); 119 | TreeViewAdapter adapter = new TreeViewAdapter(nodes, Arrays.asList(new FileNodeBinder(), new DirectoryNodeBinder())); 120 | rv.setAdapter(adapter); 121 | ``` 122 | 123 | - set TreeNodeListener to TreeViewAdapter 124 | 125 | ```java 126 | adapter.setOnTreeNodeListener(new TreeViewAdapter.OnTreeNodeListener() { 127 | @Override 128 | public boolean onClick(TreeNode node, RecyclerView.ViewHolder holder) { 129 | if (!node.isLeaf()) { 130 | //Update and toggle the node. 131 | onToggle(!node.isExpand(), holder); 132 | } 133 | return false; 134 | } 135 | 136 | @Override 137 | public void onToggle(boolean isExpand, RecyclerView.ViewHolder holder) { 138 | DirectoryNodeBinder.ViewHolder dirViewHolder = (DirectoryNodeBinder.ViewHolder) holder; 139 | final ImageView ivArrow = dirViewHolder.getIvArrow(); 140 | int rotateDegree = isExpand ? 90 : -90; 141 | ivArrow.animate().rotationBy(rotateDegree) 142 | .start(); 143 | } 144 | }); 145 | ``` 146 | 147 | 148 | 149 | Please check out the Demo and source code for more information.
