本文实例为大家分享了Android实现淘宝秒杀的具体代码，供大家参考，具体内容如下

目录结构

效果图：

imageViewHolder

public class imageViewHolder extends RecyclerView.ViewHolder { 
 
 public ImageView imageView; 
 
 public imageViewHolder(View itemView) { 
  super(itemView); 
  imageView = (ImageView) itemView; 
 } 
} 

MyViewHolder

public class MyViewHolder extends RecyclerView.ViewHolder { 
 
 public TextView textView; 
 
 public MyViewHolder(View itemView) { 
  super(itemView); 
  textView = (TextView) itemView; 
 } 
} 

recycleAdapter

package com.nodeprogress.snapupview.SnapUp; 
 
import android.content.Context; 
import android.graphics.Color; 
import android.support.v7.widget.RecyclerView; 
import android.view.ViewGroup;

import android.widget.TextView; 
 
public class recycleAdapter extends RecyclerView.Adapter { 
 
 Context context; 
 
 public recycleAdapter(Context context) { 
  this.context = context; 
 } 
 
 
 @Override 
 public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
 
  if (viewType == 0){ 
   return new imageViewHolder(new ImageView(context)); 
  }else { 
   return new MyViewHolder(new TextView(context)); 
  } 
 } 
 
 @Override 
 public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 
  if (getItemViewType(position) == 0) { 
   imageViewHolder viewHolder = (imageViewHolder) holder; 
   viewHolder.imageView.setPadding(150,20,20,20); 
   viewHolder.imageView.setBackgroundColor(Color.BLUE); 
  } else { 
   MyViewHolder viewHolder = (MyViewHolder) holder; 
   viewHolder.textView.setText(" 淘宝 " + position); 
  } 
 } 
 
 @Override 
 public int getItemCount() { 
  return 21; 
 }
