當RecyclerView有下拉刷新時，有時候設計圖上，體現(xiàn)出來的列表有頭部布局，這可以通過Adapter實現(xiàn)加載多套布局就可以，這里以加載兩種布局為例說明。

先看看Adapter的代碼

import android.annotation.SupPRessLint;import android.content.Context;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import com.alvin.R;import java.util.ArrayList;import java.util.List;public class MainListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder>{ private List<Data> list; private ArrayList<ItemEntity> jdList; private Context context; public MainListAdapter(List<Data> list,ArrayList<ItemEntity> jdList, Context context) { this.list = list; this.jdList = jdList; this.context = context; } @Override public int getItemViewType(int position) { return list.get(position).getShowType(); } @Override public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { if(viewType==1){ View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_header_main_list,parent,false); return new HeaderHolder(view); }else{ View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_list_main,parent,false); return new ViewHolderItem(view); } } @Override public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { if(holder instanceof HeaderHolder){ final HeaderHolder headerHolder = (HeaderHolder) holder; //TODO 實現(xiàn)相關邏輯 }else if(holder instanceof ViewHolderItem){ } } @Override public int getItemCount() { return list.size(); } private class HeaderHolder extends RecyclerView.ViewHolder{ HeaderHolder(View itemView) { super(itemView); } } private class ViewHolderItem extends RecyclerView.ViewHolder{ ViewHolderItem(View itemView) { super(itemView); } }}
