## DataBinding RecyclerViewAdapter
Super simple RecyclerView adapter using Data Binding Technology, no longer need to write any adapter! You don't need to write any extra class like ViewHolder or ItemView.
It`s Based on [markzhai/DataBindingAdapter](https://github.com/markzhai/DataBindingAdapter) and [tianzhijiexian/CommonAdapter](https://github.com/tianzhijiexian/CommonAdapter)
Combined with the Characteristics of the two, make `Adapter` easier to use
## Get Started
`AdapterItem`:
```Java
public class EmployerItem implements AdapterItem {
//...
@Override public int getLayoutResId() {
return R.layout.item_employer;// layout res
}
@Override public Integer getVariableId() {
return BR.item; // xml中的item
}
@Override public Decorator getDecorator() {
return null; // item Decorator
}
@Override public Map getBindData() {
Map map = new HashMap<>();
map.put(BR.presenter, new EmployerPresenter());
return map; // item <-> Variable
}
public class EmployerPresenter {//presenter
public void onItemClick(EmployerViewModel model) {
Toast.makeText(context, "employer " + model.name, Toast.LENGTH_SHORT).show();
}
}
}
```
`CommonAdapter`:
```Java
public class MainAdapter extends CommonAdapter {
//...
@NonNull @Override public AdapterItem createItem(int viewType) {
return adapterItem;
}
@Override public int getViewType(Object _o) {
return viewType;
}
}
```
## Listener Binding
An easy way to add listener binding
```java
holder.getBinding().setVariable(key, value);
```
Do not have their own settings, only need to set up presenter，Such as：
```java
public class EmployerPresenter {//presenter
public void onItemClick(EmployerViewModel model) {
Toast.makeText(context, "employer " + model.name, Toast.LENGTH_SHORT).show();
}
}
```
## Decorator
A Decorator is provided to let user implement and set ,With it we can do some extra works in onBindViewHolder
```java
AdapterItem.Decorator decorator = adapterItem.getDecorator();
if (decorator != null) {
decorator.decorator(holder, position, getItemViewType(position));
}
//adapter
@Override public Decorator getDecorator() {
return null; // return AdapterItem.Decorator
}
```
