获取 listview 列表每行数据

ArrayList<String> listArray = new ArrayList<String>();// listView data

java.util.Iterator it1 = listItem.iterator();final String[] getValue = new String[20];// 返回配置值 数组 0 -9int f = 0;while (it1.hasNext()) {Object value = it1.next();String value_str = value.toString();Pattern pattern;Matcher matcher;pattern = Pattern.compile("ItemValue=(.*?),");matcher = pattern.matcher(value_str);matcher.find();getValue[f] = matcher.group(1); f++;}////ArrayList<HashMap<String, Object>> listItem = new ArrayList<HashMap<String,Object>>();
