for (HashMap<String,String> hashMap : yourArrayList)
    {
        // For each hashmap,iterate over it
        for (Map.Entry<String,String> entry  : hashMap.entrySet())
        {
           // Do something with your entrySet,for example get the key.
           String sListName = entry.getKey();
        }
    }

您的Hashmap可能使用其他类型,这个使用字符串.
