Android定时器和倒计时实现淘宝秒杀功能

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;
}

}
