Question

我希望获得带有复选框的列表视图的位置文本.Listview包含来自baseadapter的textview和复选框

    holder = new ViewHolder();
            holder.full_name = (TextView) convertView
                    .findViewById(R.id.social_name);
            holder.social_network_pic = (ImageView)convertView.findViewById(R.id.social_image);
            holder.checkBox = (CheckBox)convertView.findViewById(R.id.social_check_box);


            convertView.setTag(holder);
            Log.e("Position=", "" + position);
            holder = (ViewHolder) convertView.getTag();
            String holderValue = socila_network_name_arraya_list.get(position).get("serviceLabel").toString();
            holder.full_name.setText(socila_network_name_arraya_list.get(position).get("serviceData").toString());
            int resID = getResources().getIdentifier(holderValue , "drawable", getPackageName());
            holder.social_network_pic.setImageResource(resID);
             holder.checkBox.setOnClickListener(CreatePost.this);
            holder.checkBox.isChecked();

之后我没有得到如何做到这一点我需要紧急：0

试用此代码

以下代码使用适配器初始化ListView

     list.setAdapter(new ArrayAdapter(Download_ReadyList.this,
                android.R.layout.simple_list_item_multiple_choice, item));
        for (int i = 0; i < result.length; i++) {
            list.setItemChecked(i, true);
        }

以下代码获取ListView以查看

int cntChoice = list.getCount();
String checked[] = new String[list.getCheckedItemCount()];
SparseBooleanArray sparseBooleanArray = list.getCheckedItemPositions();

            ArrayList<HashMap<String, String>> list_offline = new ArrayList<HashMap<String, String>>();
            int Count = 0;
            for (int i = 0; i < cntChoice; i++) {
                if (sparseBooleanArray.get(i) == false) {
                    checked[Count] = list.getItemAtPosition(i).toString();

                    Count++;
                }
            }
