## 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 

```
