这篇文章主要介绍了Android listview ExpandableListView实现多选，单选，全选，edittext实现批量输入的实例代码,非常不错，具有参考借鉴价值，需要的朋友可以参考下
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：

子条目点击事件处理：

// 刷新界面
adapter.notifyDataSetChanged();
return true;
}
