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;
 }

ExpandableListView实现子条目单选：


class PinnedHeaderExpandableAdapter extends BaseExpandableListAdapter implements HeaderAdapter {
 private Context context;
 private PinnedHeaderExpandableListView listView;
 private LayoutInflater inflater;
 private Map<String, List<DtGzsCustomer>> map;
 private List<String> parentList;

 this.map = new HashMap<String, List<DtGzsCustomer>>();
 if (map != null) {
 this.map.putAll(map);

 }
 public void notifyMap(Map<String, List<DtGzsCustomer>> map) {

 notifyDataSetChanged();
 }
 public void notifyParent(List<String> parentList) {

 }
 @Override
 public int getChildrenCount(int groupPosition) {
 if (groupPosition != -1) {
 String key = parentList.get(groupPosition);
 return map.get(key).size();
 } else {
 return 0;
 }
 }
 @Override
 public Object getChild(int groupPosition, int childPosition) {
 String key = parentList.get(groupPosition);// 根据组名位置的值作为map的key去获取value
 DtGzsCustomer dtGzsCustomer = map.get(key).get(childPosition);
 return dtGzsCustomer.sales_consultant_name;
 }
 @Override
 public long getChildId(int groupPosition, int childPosition) {
 return childPosition;
 }
 @Override
 public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
 convertView = inflater.inflate(R.layout.child, null);
 TextView text = (TextView) convertView.findViewById(R.id.childto);
 ImageView iv = (ImageView) convertView.findViewById(R.id.iv);
 // 判断item的位置是否相同，如相同，则表示为选中状态，更改其背景颜色，如不相同，则设置背景色为白色
 if (group_groupId == groupPosition && child_childId == childPosition) {
 iv.setImageResource(R.drawable.login_check);
 } else {
 iv.setImageResource(R.drawable.login_uncheck);
 }
 String key = parentList.get(groupPosition);
 List<DtGzsCustomer> list = map.get(key);
 DtGzsCustomer childernItem = list.get(childPosition);
 SalesTools.setTextViewText(text, childernItem.sales_consultant_name);
 return convertView;
 }
 @Override
 public Object getGroup(int groupPosition) {
 return parentList.get(groupPosition);
 }
 @Override
 public int getGroupCount() {
 return parentList.size();
 }
 @Override
 public long getGroupId(int groupPosition) {

 ImageView iv = (ImageView) convertView.findViewById(R.id.groupIcon);
 TextView tv = (TextView) convertView.findViewById(R.id.groupto);
 if (isExpanded) {
 iv.setImageResource(R.drawable.btn_arrow_up);
 } else {

 }
 SalesTools.setTextViewText(tv, parentList.get(groupPosition));
 return convertView;
 }
 @Override

 if (childPosition == childCount - 1) {
 return PINNED_HEADER_PUSHED_UP;
 } else if (childPosition == -1 && !listView.isGroupExpanded(groupPosition)) {

 return groupStatusMap.get(groupPosition);
 } else {
 return 0;
 }
 }
 public void notifyDataSetChanged() {// 通知数据发生变化
 super.notifyDataSetChanged();
 }
 }

子条目点击事件处理：


// 子条目的点击事件
 @Override
 public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
 // Toast.makeText(SaleNameActivity.this, "点击了" + groupPosition +
 // childPosition, Toast.LENGTH_LONG).show();
 // 将被点击的一丶二级标签的位置记录下来
 String key = groupData.get(groupPosition);
 List<DtGzsCustomer> list = map.get(key);
 DtGzsCustomer dtGzsCustomer = list.get(childPosition);
 sales_consultant_name = dtGzsCustomer.sales_consultant_name;
 sales_consultant_id = dtGzsCustomer.sales_consultant_id;
 group_groupId = groupPosition;
 child_childId = childPosition;
 // 刷新界面
 adapter.notifyDataSetChanged();
 return true;
 }

listview和edittext实现批量输入：


class SetAdapter extends BaseAdapter {
 private List<DtGzsCustomer> goalList;
 private Context context;
 public SetAdapter(Context context, List<DtGzsCustomer> goalList) {
 this.context = context;
 this.goalList = new ArrayList<DtGzsCustomer>();

 this.goalList.addAll(goalList);
 }
 notifyDataSetChanged();
 }
 @Override
 public int getCount() {
 return goalList.size();
 }
 @Override
 public Object getItem(int position) {
 return goalList.get(position);
 }
 @Override
 public long getItemId(int position) {

 @Override
 public View getView(final int position, View convertView, ViewGroup parent) {

  String value = entry.getValue();
  if (value==null||value.length()==0) {
  value="0";
  }
  sum=sum+Integer.parseInt(value);
  }
  tv_order.setText("订车"+sum+"台");
 }
 };
 holder.et_order.addTextChangedListener(orderTitle);
 holder.et_order.setTag(orderTitle);
 TextWatcher carContent = new SimpleTextWatcher() {

  String return_num = dtGzsCustomer.return_num.replace("0", "");
  carMap.put(sales_consultant_id, return_num);
  }else{

  carMap.put(sales_consultant_id, return_num);
  }
  Iterator<Map.Entry<String, String>> it = carMap.entrySet().iterator();
  while(it.hasNext()){

  }
  tv_return.setText("交车"+sum+"台");
 }
 };
 holder.et_car.addTextChangedListener(carContent);
 holder.et_car.setTag(carContent);
 return convertView;
 }
 /**
 * 去除textWatcher
 *
 * @param editText
 */
 private void removeTextWatcher(EditText editText) {
 if (editText.getTag() instanceof TextWatcher) {
 editText.removeTextChangedListener((TextWatcher) editText.getTag());
 }
 }
 }
 class ViewHolder {
 EditText et_order, et_car;
 TextView sale_name;
 }

以下是效果显示：
