# RecyclerAdapter
在想着尽可能保留原味，又想简化代码工作量的情况下封装了 RecyclerView.Adapter。
## Installation
add the dependency to your build.gradle:
```
compile 'com.github.nukc:recycleradapter:0.2.1'
```
## Usage
设置 Adapter
```java
recyclerView.setAdapter(new RecyclerAdapter(mItemListener) {
@Override
public ItemWrapper getItemHolder(int position) {
// 可获取到对应的 model ，可根据实际需求返回不一样的 Item
// NumberItem numberItem = getItem(position);
return new ItemWrapper(R.layout.item, ItemHolder.class);
}
});
```
继承 RecyclerHolder 。 (class RecyclerHolder extends RecyclerView.ViewHolder )
在原有的 ViewHolder 上增加了一个抽象方法 onBindView(T t)。
```java
//NumberItem 是 sample 中的 Model
static class ItemHolder extends RecyclerHolder {
private TextView mTextView;
private OnItemListener mItemListener;
public ItemHolder(View itemView, OnItemListener listener) {
super(itemView);
mTextView = (TextView) itemView.findViewById(R.id.text);
mItemListener = listener;
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (mItemListener != null) {
mItemListener.onItemClick(view, getAdapterPosition());
}
}
});
}
@Override
public void onBindView(NumberItem item) {
mTextView.setText("+" + item.getNumber());
}
}
```
监听点击事件
```java
interface OnItemListener {
void onItemClick(View view, int position);
}
private OnItemListener mItemListener = new OnItemListener() {
@Override
public void onItemClick(View view, int position) {
NumberItem numberItem = mNumberList.get(position);
Toast.makeText(MainActivity.this, "number=" + numberItem.getNumber(), Toast.LENGTH_SHORT).show();
}
};
```
## About
Adapter 方法说明
> 对数据操作的方法，最后都会 notify
方法名 | 备注
:------------- | :-------------
getItem(position) | 获取对应的 item
getItemCount() | 获取 item 的数量
getDataList() | 获取数据集合
refresh(dataList) | 清空原先的数据再加入新的数据后刷新
add(position, data) | 在指定位置插入
add(data) | 在最后位置插入
addAll(positionStart, dataList) | 在指定开始位置插入一个集合
addAll(dataList) | 在最后位置插入一个集合
move(fromPosition, toPosition) | 把 fromPosition 的 item 移动到 toPosition
change(position, data) | 改变指定位置的数据，然后刷新 item
remove(position) | 移除指定位置的 item
clear() | 清空
setItemListener(listener) | 设置监听，也可在构造方法中传入
getItemHolder(position) | 获取指定位置的 ItemWrapper ，该方法由 ItemProvide 接口声明，继承 RecyclerAdapter 需要实现该方法
ItemWrapper 说明
> 该类用于控制 itemView 的 Type
变量成员 | 备注
:------------- | :-------------
mLayoutResId | 布局文件Id
mHolderClass | RecyclerHolder 的子类 Class
欢迎大家 PR 、提 issues ，一起加入更多方便实用的方法。
## Proguard
```
-keepclassmembers public class * extends com.github.nukc.recycleradapter.RecyclerHolder {
public (...);
}
```
