Android listview ExpandableListView实现多选，单选，全选，edittext实现批量输入的实例代码

最近在项目开发中，由于项目的需求要实现一些列表的单选，多选，全选，批量输入之类的功能，其实功能的实现倒不是很复杂，需求中也没有涉及到复杂的动画什么之类，主要是解决列表数据复用的问题，解决好这个就可以了。下面是最近项目中涉及到的一些：

listview实现多选、全选、取消全选：

下面是适配器，一开始在适配器的构造函数中，对数据进行初始化，同时定义一个集合用于管理listview的点击；

class batchadpter extends baseadapter {
 private hashmap<integer, boolean> isselected;
 private list<dtgzscustomer> list;
 private context context;
 @suppresslint("usesparsearrays")
 public batchadpter(list<dtgzscustomer> list,context context) {
 this.context=context;
 this.list = new arraylist<dtgzscustomer>();
 if (list != null) {
 this.list.addall(list);
 }
 isselected = new hashmap<integer, boolean>();
 initdate(false);
 }
 // 初始化isselected的数据
 private void initdate(boolean bool) {
 for (int i = 0; i < list.size(); i++) {
 dtgzscustomer dtgzscustomer = list.get(i);
 if (bool) {  
  datas.add(dtgzscustomer.thread_id);
 } else {
  datas.remove(dtgzscustomer.thread_id);
 }
 getisselected().put(i, bool);
 }
 }
 public hashmap<integer, boolean> getisselected() {
 return isselected;
 }
 public void setisselected(hashmap<integer, boolean> isselected) {
 this.isselected = isselected;
 }
 public void nodfiydata(list<dtgzscustomer> list) {
 if (list != null) {
 this.list.clear();
 this.list.addall(list);
 }
 notifydatasetchanged();
 }
 @override
 public int getcount() {
 return list.size();
 }
 @override
 public object getitem(int position) {
 return list.get(position);
 }
 @override
 public long getitemid(int position) {
 return position;
 }
 @override
 public view getview(int position, view convertview, viewgroup parent) {
 viewholder holder;
 if (convertview == null) {
 holder = new viewholder();
 convertview = view.inflate(context, r.layout.no_contact_listview_item, null);
 holder.name = (textview) convertview.findviewbyid(r.id.name);
 holder.sex = (textview) convertview.findviewbyid(r.id.sex);
 holder.popuse = (textview) convertview.findviewbyid(r.id.popuse);
 holder.tv_phone = (textview) convertview.findviewbyid(r.id.tv_phone);
 holder.allocation = (textview) convertview.findviewbyid(r.id.allocation);
 holder.time = (textview) convertview.findviewbyid(r.id.time);
 holder.btn_dis = (button) convertview.findviewbyid(r.id.btn_dis);
 holder.btn_allot = (button) convertview.findviewbyid(r.id.btn_allot);
 holder.btn_telephone = (button) convertview.findviewbyid(r.id.btn_telephone);
 holder.btn_follow = (button) convertview.findviewbyid(r.id.btn_follow);
 holder.cb = (checkbox) convertview.findviewbyid(r.id.cb);
 holder.allocation.setvisibility(view.invisible);
 convertview.settag(holder);
 } else {
 holder = (viewholder) convertview.gettag();
 }
 dtgzscustomer data = list.get(position);
 salestools.settextviewtext(holder.name, data.p_customer_name);
 salestools.settextviewtext(holder.sex, data.gender);
 salestools.settextviewtext(holder.popuse, data.purpose_series);
 salestools.settextviewtext(holder.tv_phone, data.mobile_no);
 salestools.settextviewtext(holder.allocation, data.thread_contact_state);
 salestools.settextviewtext(holder.time, data.thread_create_date);
 holder.btn_dis.setvisibility(view.invisible);
 holder.btn_allot.setvisibility(view.invisible);
 holder.btn_telephone.setvisibility(view.invisible);
 holder.btn_follow.setvisibility(view.invisible);
 holder.cb.setvisibility(view.visible);
 hashmap<integer, boolean> isselected2 = getisselected();
 boolean boolean1 = isselected2.get(position);
 if (boolean1 != null) {
 holder.cb.setchecked(boolean1);
 }
 // 初始化的时候做处理，如果管理标记的集合中没有该pos则设为false如果有则设为true
 if (adapter != null) {
 hashmap<integer, boolean> isselected = adapter.getisselected();
 if (isselected != null && isselected.containskey(position)) {
  holder.cb.setchecked(isselected.get(position));
 } else {
  holder.cb.setchecked(false);
 }
 }
 return convertview;
 }
 }
 class viewholder {
 textview name, sex, popuse, tv_phone, allocation, time;
 button btn_dis, btn_allot, btn_telephone, btn_follow;
 checkbox cb;
 }

这里是全选的方法：

// 全选
 private void choiceall() {
 adapter.initdate(true);
 // 数量设为list的长度
 checknum = list.size();
 // 刷新listview和textview的显示
 cb_all.settextcolor(color.parsecolor("#0097e0"));
 datachanged();
 }

这里是条目点击事件：

@override
 public void onitemclick(adapterview<?> parent, view view, int position, long id) {
 dtgzscustomer dtgzscustomer = list.get(position);
 // 取得viewholder对象，这样就省去了通过层层的findviewbyid去实例化我们需要的cb实例的步骤
 viewholder holder = (viewholder) view.gettag();
 // 改变checkbox的状态
 holder.cb.toggle();
 // 将checkbox的选中状况记录下来
 adapter.getisselected().put(position, holder.cb.ischecked());
 // 调整选定条目
 if (holder.cb.ischecked() == true) {
 checknum++;
 if (checknum==list.size()) {
 cb_all.setchecked(true);
 cb_all.settextcolor(color.parsecolor("#0097e0"));
 }
 datas.add(dtgzscustomer.thread_id);
 } else {
 cb_all.setchecked(false);
 cb_all.settextcolor(color.parsecolor("#c0c0c0"));
 checknum--;
 datas.remove(dtgzscustomer.thread_id);
 }
 datachanged();
 }

下面是listview和radionbutton实现单个条目单选，整个列表多线：

class checkadapter extends baseadapter {
 private context mcontext;
 private list<dtgzsschedule> list;
 public checkadapter(context context, list<dtgzsschedule> list) {
 this.mcontext = context;
 this.list=list;
 }
 @override
 public int getcount() {
 return list.size();
 }
 @override
 public object getitem(int position) {
 return list.get(position);
 }
 @override
 public long getitemid(int position) {
 return position;
 }
 @override
 public view getview(int position, view convertview, viewgroup parent) {
 viewholder holder;
 if (convertview==null) {
 holder=new viewholder();
 convertview=layoutinflater.from(mcontext).inflate(r.layout.check_listview_item, parent, false);
 holder.sale_name = (textview) convertview.findviewbyid(r.id.sale_name);
 holder.sale_branch = (textview) convertview.findviewbyid(r.id.sale_branch);
 holder.scb = (radiobutton) convertview.findviewbyid(r.id.scb);
 holder.scc = (radiobutton) convertview.findviewbyid(r.id.scc);
 holder.scd = (radiobutton) convertview.findviewbyid(r.id.scd);
 holder.sce = (radiobutton) convertview.findviewbyid(r.id.sce);
 convertview.settag(holder);
 }else{
 holder=(viewholder) convertview.gettag();
 }
 final dtgzsschedule dtgzsschedule = list.get(position);
 oncheckedchangelistener listener = new oncheckedchangelistener() {
 @override
 public void oncheckedchanged(compoundbutton buttonview, boolean ischecked) {
  string choice = buttonview.gettext().tostring();
  if (choice.equals("到岗")) {
  if (ischecked == true) {
  dtgzsschedule.check_type = "0";
  setactualnum();
  }
  } else {
  if (choice.equals("迟到")) {
  if (ischecked == true) {
  dtgzsschedule.check_type = "1";
  setactualnum();
  }
  } else if (choice.equals("休假")) {
  if (ischecked == true) {
  dtgzsschedule.check_type = "2";
  setactualnum();
  }
  } else if (choice.equals("旷工")) {
  if (ischecked == true) {
  dtgzsschedule.check_type = "3";
  setactualnum();
  }
  }
  }
 }
 };
 holder.sce.setoncheckedchangelistener(listener);
 holder.scd.setoncheckedchangelistener(listener);
 holder.scc.setoncheckedchangelistener(listener);
 holder.scb.setoncheckedchangelistener(listener);
 holder.sale_name.settext("" + dtgzsschedule.sales_consultant_name);
 holder.sale_branch.settext("" + dtgzsschedule.sales_branch);
 string check_type = dtgzsschedule.check_type;
 if (check_type.equals("0")) {// 到岗
 dtgzsschedule.scbchecked = true;
 dtgzsschedule.sccchecked = false;
 dtgzsschedule.scdchecked = false;
 dtgzsschedule.scechecked = false;
 } else if (check_type.equals("1")) {// 迟到
 dtgzsschedule.scbchecked = false;
 dtgzsschedule.sccchecked = true;
 dtgzsschedule.scdchecked = false;
 dtgzsschedule.scechecked = false;
 } else if (check_type.equals("2")) {// 旷工
 dtgzsschedule.scbchecked = false;
 dtgzsschedule.sccchecked = false;
 dtgzsschedule.scdchecked = true;
 dtgzsschedule.scechecked = false;
 } else if (check_type.equals("3")) {// 休假
 dtgzsschedule.scbchecked = false;
 dtgzsschedule.sccchecked = false;
 dtgzsschedule.scdchecked = false;
 dtgzsschedule.scechecked = true;
 }
 holder.scb.setchecked(dtgzsschedule.scbchecked);
 holder.scc.setchecked(dtgzsschedule.sccchecked);
 holder.scd.setchecked(dtgzsschedule.scdchecked);
 holder.sce.setchecked(dtgzsschedule.scechecked);
 return convertview;
 }
 }
 class viewholder{
 textview sale_name, sale_branch;
 radiobutton scb, scc, scd, sce;
 }

 // 刷新界面
