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.ImageView; 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;   }    @Override   public int getItemViewType(int position) {     return (position == 20) ? 0 : 1;   }  }
