# RecyclerTreeView
[](https://jitpack.io/#TellH/RecyclerTreeView)
TreeView implement in Android with RecyclerView..
## Effect
## Usage
### Setup
root build.gradle
```groovy
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}
```
app build.gradle
```groovy
dependencies {
compile 'com.github.TellH:RecyclerTreeView:1.2.0'
}
```
### Quick Start
- Create a Java bean class and implement the LayoutItemType, to attach item layout id to it.
```java
public class Dir implements LayoutItemType {
public String dirName;
public Dir(String dirName) {
this.dirName = dirName;
}
@Override
public int getLayoutId() {
return R.layout.item_dir;
}
}
```
- 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.
```java
public class FileNodeBinder extends TreeViewBinder {
@Override
public ViewHolder provideViewHolder(View itemView) {
return new ViewHolder(itemView);
}
@Override
public void bindView(ViewHolder holder, int position, TreeNode node) {
File fileNode = (File) node.getContent();
holder.tvName.setText(fileNode.fileName);
}
@Override
public int getLayoutId() {
return R.layout.item_file;
}
public class ViewHolder extends TreeViewBinder.ViewHolder {
public TextView tvName;
public ViewHolder(View rootView) {
super(rootView);
this.tvName = (TextView) rootView.findViewById(R.id.tv_name);
}
}
}
```
- Add TreeNode to TreeViewAdapter.
```java
List nodes = new ArrayList<>();
TreeNode app = new TreeNode<>(new Dir("app"));
nodes.add(app);
app.addChild(
new TreeNode<>(new Dir("manifests"))
.addChild(new TreeNode<>(new File("AndroidManifest.xml")))
);
app.addChild(
new TreeNode<>(new Dir("java")).addChild(
new TreeNode<>(new Dir("tellh")).addChild(
new TreeNode<>(new Dir("com")).addChild(
new TreeNode<>(new Dir("recyclertreeview"))
.addChild(new TreeNode<>(new File("Dir")))
.addChild(new TreeNode<>(new File("DirectoryNodeBinder")))
.addChild(new TreeNode<>(new File("File")))
.addChild(new TreeNode<>(new File("FileNodeBinder")))
.addChild(new TreeNode<>(new File("TreeViewBinder")))
)
)
)
);
TreeNode res = new TreeNode<>(new Dir("res"));
nodes.add(res);
res.addChild(
new TreeNode<>(new Dir("layout"))
.addChild(new TreeNode<>(new File("activity_main.xml")))
.addChild(new TreeNode<>(new File("item_dir.xml")))
.addChild(new TreeNode<>(new File("item_file.xml")))
);
res.addChild(
new TreeNode<>(new Dir("mipmap"))
.addChild(new TreeNode<>(new File("ic_launcher.png")))
);
TreeViewAdapter adapter = new TreeViewAdapter(nodes, Arrays.asList(new FileNodeBinder(), new DirectoryNodeBinder()));
rv.setAdapter(adapter);
```
- set TreeNodeListener to TreeViewAdapter
```java
adapter.setOnTreeNodeListener(new TreeViewAdapter.OnTreeNodeListener() {
@Override
public boolean onClick(TreeNode node, RecyclerView.ViewHolder holder) {
if (!node.isLeaf()) {
//Update and toggle the node.
onToggle(!node.isExpand(), holder);
}
return false;
}
@Override
public void onToggle(boolean isExpand, RecyclerView.ViewHolder holder) {
DirectoryNodeBinder.ViewHolder dirViewHolder = (DirectoryNodeBinder.ViewHolder) holder;
final ImageView ivArrow = dirViewHolder.getIvArrow();
int rotateDegree = isExpand ? 90 : -90;
ivArrow.animate().rotationBy(rotateDegree)
.start();
}
});
```
