android listview ExpandableListView實現多選,單選,全選,edittext實現批量輸入

編輯:關於Android編程

最近在項目開發中,由於項目的需求要實現一些列表的單選,多選,全選,批量輸入之類的功能,其實功能的實現倒不是很復雜,需求中也沒有涉及到復雜的動畫什麼之類,主要是解決列表數據復用的問題,解決好這個就可以了。下面是最近項目中涉及到的一些:
listview實現多選、全選、取消全選:
下面是適配器,一開始在適配器的構造函數中,對數據進行初始化,同時定義一個集合用於管理listview的點擊;

class BatchAdpter extends BaseAdapter {

        private HashMap isSelected;
        private List list;
        private Context context;
        @SuppressLint("UseSparseArrays")
        public BatchAdpter(List list,Context context) {
            this.context=context;
            this.list = new ArrayList();
            if (list != null) {
                this.list.addAll(list);
            }
            isSelected = new HashMap();
            initDate(false);
        }

        // 初始化isSelected的數據
        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 getIsSelected() {
            return isSelected;
        }

        public void setIsSelected(HashMap isSelected) {
            this.isSelected = isSelected;
        }

        public void nodfiyData(List 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 isSelected2 = getIsSelected();
            Boolean boolean1 = isSelected2.get(position);
            if (boolean1 != null) {
                holder.cb.setChecked(boolean1);
            }
            // 初始化的時候做處理,如果管理標記的集合中沒有該pos則設為false如果有則設為true
            if (adapter != null) {
                HashMap 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;
    }
這裡是全選的方法:
// 全選
    private void choiceAll() {
        adapter.initDate(true);
        // 數量設為list的長度
        checkNum = list.size();
        // 刷新listview和TextView的顯示
        cb_all.setTextColor(Color.parseColor("#0097e0"));
        dataChanged();
    }

這裡是條目點擊事件:

@Override
    public void onItemClick(AdapterView parent, View view, int position, long id) {
        DtGzsCustomer dtGzsCustomer = list.get(position);
        // 取得ViewHolder對象,這樣就省去了通過層層的findViewById去實例化我們需要的cb實例的步驟
        ViewHolder holder = (ViewHolder) view.getTag();
        // 改變CheckBox的狀態
        holder.cb.toggle();
        // 將CheckBox的選中狀況記錄下來
        adapter.getIsSelected().put(position, holder.cb.isChecked());
        // 調整選定條目
        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實現單個條目單選,整個列表多線:

class CheckAdapter extends BaseAdapter {
        private Context mContext;
        private List list;
        public CheckAdapter(Context context, List 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("到崗")) {
                        if (isChecked == true) {
                            dtGzsSchedule.check_type = "0";
                            setActualNum();
                        }
                    } else {
                        if (choice.equals("遲到")) {
                            if (isChecked == true) {

                            }
                        } else if (choice.equals("休假")) {
                            if (isChecked == true) {
                                dtGzsSchedule.check_type = "2";
                                setActualNum();
                            }
                        } else if (choice.equals("曠工")) {
                            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")) {// 到崗
                dtGzsSchedule.scbChecked = true;
                dtGzsSchedule.sccChecked = false;
                dtGzsSchedule.scdChecked = false;
                dtGzsSchedule.sceChecked = false;
            } else if (check_type.equals("1")) {// 遲到

        }
    }
    class ViewHolder{
        TextView sale_name, sale_branch;
        RadioButton scb, scc, scd, sce;
    }

ExpandableListView實現子條目單選:

class PinnedHeaderExpandableAdapter extends BaseExpandableListAdapter implements HeaderAdapter {
        private Context context;

        }

        private SparseIntArray groupStatusMap = new SparseIntArray();

        @Override
        public void setGroupClickStatus(int groupPosition, int status) {
            groupStatusMap.put(groupPosition, status);
        }

        @Override

            if (groupStatusMap.keyAt(groupPosition) >= 0) {
                return groupStatusMap.get(groupPosition);
            } else {
                return 0;
            }
        }

        public void notifyDataSetChanged() {// 通知數據發生變化
            super.notifyDataSetChanged();
        }
    }

子條目點擊事件處理:

// 子條目的點擊事件
    @Override
    public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
        // Toast.makeText(SaleNameActivity.this, "點擊了" + groupPosition +
        // childPosition, Toast.LENGTH_LONG).show();
        // 將被點擊的一丶二級標簽的位置記錄下來
        String key = groupData.get(groupPosition);
        List 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實現批量輸入:

class SetAdapter extends BaseAdapter {
        private List goalList;
        private Context context;
        public SetAdapter(Context context, List goalList) {
            this.context = context;
            this.goalList = new ArrayList();
            if (goalList != null) {
                this.goalList.addAll(goalList);
            }
        }

        public void nodfiyData(List goalList) {
            if (goalList != null) {
                this.goalList.clear();
                this.goalList.addAll(goalList);
            }
            notifyDataSetChanged();
        }

        @Override
        public int getCount() {
            return goalList.size();
        }
