一、上图
二、图片功能解说
1、点击ListView中其中的一项，Item中处于隐藏状态的操作按钮部分布局显示,其他项显示的布局同时被隐藏，再次点击该项，操作按钮部分布局再次隐藏。
2、点击各个按钮，分别弹出哪个按钮被点击（也就是点击每一个按钮分别处理不同按钮的业务功能）。
三、实现代码主要处于适配器的处理。见如下代码:
package com.test.listviewbtn.adapters;import java.util.ArrayList;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.Button;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.TextView;import android.widget.Toast;import com.test.listviewbtn.R;import com.test.listviewbtn.beans.LvItemBean;public class LvAdapter extends BaseAdapter {private ArrayList<LvItemBean> lvItemBeanList;// 布局加载器private LayoutInflater mInflater;// 上下文private Context context;// 布局缓存对象private ViewHolder holder;//记录当前展开项的索引private int expandPosition = -1;public LvAdapter(ArrayList<LvItemBean> lvItemBeanList, Context context) {super();this.lvItemBeanList = lvItemBeanList;this.context = context;mInflater = LayoutInflater.from(context);}@Overridepublic int getCount() {return null == lvItemBeanList ? 0 : lvItemBeanList.size();}@Overridepublic Object getItem(int position) {return lvItemBeanList.get(position);}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {if (null == convertView) {convertView = mInflater.inflate(R.layout.activity_main_listview_item, null);holder = new ViewHolder();holder.tv1 = (TextView) convertView.findViewById(R.id.tv_1);holder.tv2 = (TextView) convertView.findViewById(R.id.tv_2);holder.tv3 = (TextView) convertView.findViewById(R.id.tv_3);holder.llItemTop = (LinearLayout) convertView.findViewById(R.id.ll_item_top);holder.llItemBottom = (LinearLayout) convertView.findViewById(R.id.ll_item_bottom);holder.bt1 = (Button) convertView.findViewById(R.id.bt_1);holder.bt2 = (Button) convertView.findViewById(R.id.bt_2);holder.bt3 = (Button) convertView.findViewById(R.id.bt_3);convertView.setTag(holder);} else {holder = (ViewHolder) convertView.getTag();}LvItemBean lvItemBean = lvItemBeanList.get(position);if (null != lvItemBean) {holder.llItemTop.setOnClickListener(new OnLvItemClickListener(position));holder.bt1.setOnClickListener(new OnBtnClickListener());holder.bt2.setOnClickListener(new OnBtnClickListener());holder.bt3.setOnClickListener(new OnBtnClickListener());//如果点击的是当前项，则将其展开，否则将其隐藏if(expandPosition == position){holder.llItemBottom.setVisibility(View.VISIBLE);}else{holder.llItemBottom.setVisibility(View.GONE);}}return convertView;}class OnLvItemClickListener implements OnClickListener {private int position;public OnLvItemClickListener(int position) {super();this.position = position;}@Overridepublic void onClick(View v) {//如果当前项为展开，，则将其置为-1，目的是为了让其隐藏，如果当前项为隐藏，则将当前位置设置给全局变量，让其展开，这也就是借助于中间变量实现布局的展开与隐藏if(expandPosition == position){expandPosition = -1;}else{expandPosition = position;}notifyDataSetChanged();}}class OnBtnClickListener implements OnClickListener{@Overridepublic void onClick(View v) {switch(v.getId()){case R.id.bt_1:Toast.makeText(context, "新增按钮被点击", 1).show();break;case R.id.bt_2:Toast.makeText(context, "修改按钮被点击", 1).show();break;case R.id.bt_3:Toast.makeText(context, "删除按钮被点击", 1).show();break;}}}class ViewHolder {TextView tv1;TextView tv2;TextView tv3;LinearLayout llItemTop;LinearLayout llItemBottom;Button bt1;Button bt2;Button bt3;ImageView ivUpDownArrow;}}
