在使用RecyclerView时候，必须指定一个适配器Adapter和一个布局管理器LayoutManager。

recyclerView=(RecyclerView)findViewById(R.id.recyclerView);

LinearLayoutManagerlayoutManager=newLinearLayoutManager(this);

//设置布局管理器 recyclerView.setLayoutManager(layoutManager);

//设置为垂直布局，这也是默认的 layoutManager.setOrientation(OrientationHelper.VERTICAL);

//设置Adapter recyclerView.setAdapter(recycleAdapter);

//设置分隔线 recyclerView.addItemDecoration(newDividerGridItemDecoration(this));

//设置增加或删除条目的动画 recyclerView.setItemAnimator(newDefaultItemAnimator());

// ① 创建Adapter

public class NormalAdapter extends RecyclerView.Adapter<NormalAdapter.VH>{

//② 创建ViewHolder 

public static class VH extendsRecyclerView.ViewHolder{

public final TextViewtitle;

public VH(Viewv) {super(v);

title=(TextView)v.findViewById(R.id.title);}} 

private List<String> mDatas;

public NormalAdapter(List<String>data){this.mDatas=data;}

//③ 在Adapter中实现3个方法

@Override

public void onBindViewHolder(VHholder,intposition){holder.title.setText(mDatas.get(position));

holder.itemView.setOnClickListener(newView.OnClickListener(){

@Override

public void onClick(Viewv){//item 点击事件}});

}

@Override

public int getItemCount(){returnmDatas.size();}

@Override

public VH onCreateViewHolder(ViewGroupparent,intviewType){

//LayoutInflater.from指定写法

View v=LayoutInflater.from(parent.getContext()).inflate(R.layout.item_1,parent,false);

return newVH(v);}}
