## TreeView
An android tree view with high performance and rich functions
[中文介绍](http://texy.me/2017/05/01/android_tree_view/)
### Captures
There are some gifs from Demo:
* Select node:
* Operate all:
### Features
- expandAll/collapseAll
- expandNode/collapseNode
- expandLevel/collapseLevel
- toggleNode
- deleteNode/addNode
- selectNode/deselectNode
- selectAll/deselectAll
- getSelectedNodes
- refreshTreeView
### Usage
**1.Reference the library from your module's build.gradle:**
```groovy
implementation 'me.texy.treeview:treeview_lib:1.0.6'
```
**2.Implement your all level's BaseNodeViewBinder**
Sample：
```java
public class FirstLevelNodeViewBinder extends BaseNodeViewBinder {
TextView textView;
public FirstLevelNodeViewBinder(View itemView) {
super(itemView);
textView = (TextView) itemView.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
.
.
.
```
If you want add the selectable feature,replace BaseNodeViewBinder with CheckableNodeViewBinder.
**3.Implement the BaseNodeViewFactory**
Sample：
```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;
}
}
}
```
If you do not want to create a class file,just implement a anonymous inner class in TreeView's constructor
**4.Add TreeView to wherever you want**
Sample:
```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
```
