我已经使用Jsoup解析了HTML，并在
items1 items2和items3中获得了Elements。我想创建一个ArrayList>以便以后使用以填充ListView。问题是我无法正确填充HashMap和/或ArrayList。
我尝试使用
Elements itemLine = document.select("selector1");
Elements itemsTime = document.select("selector2");
...
for (Element itemLine : itemLines) {
hashMap.put("itemLine", itemLine.text());
}
...
arrayList.add(hashMap);
