PRivate Context context; private String[] beans; // 用來控制CheckBox的選中狀況 private static HashMap<Integer, Boolean> isSelected; class ViewHolder { TextView tvName; CheckBox cb; } public ListViewAdapter(Context context, String[] beans) { // TODO Auto-generated constructor stub this.beans = beans; this.context = context; isSelected = new HashMap<Integer, Boolean>(); // 初始化數據 initDate(); } // 初始化isSelected的數據 private void initDate() { for (int i = 0; i < beans.length; i++) { getIsSelected().put(i, false); } } @Override public View getView(final int position, View convertView, ViewGroup parent) { // 監聽checkBox并根據原來的狀態來設置新的狀態 holder.cb.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if (isSelected.get(position)) { isSelected.put(position, false); setIsSelected(isSelected); } else { isSelected.put(position, true); setIsSelected(isSelected); } } }); // 根據isSelected來設置checkbox的選中狀況 holder.cb.setChecked(getIsSelected().get(position)); return convertView; } public static HashMap<Integer, Boolean> getIsSelected() { return isSelected; } public static void setIsSelected(HashMap<Integer, Boolean> isSelected) { ListViewAdapter.isSelected = isSelected; }
