Question

我想创建hashmap.how它可能 我希望此类型的hashmap如下所示

{Question=how are you, friend=mack}
{Question=how are you, friend=jack}
{Question=hello, friend=mack}
{Question=hello, friend=jack}

如何从代码下面获取此类地图

map_friend = webservice.getFrend(); //{0=Mack, 1=jack}
map_QUE = webservice.getQuestion();//{0=How are you, 1=hello}

int RQSize = map_QUE.size();
int Isize = map_ITEM.size();
     for (i = 0; i < RQSize; i++) 
     {

                rate_map = new HashMap<String, String>();
        final String val = map_QUE.get(i);

        rate_map.put("Question", val);
        mylist.add(rate_map);


        for (j = 0; j < Isize; j++) 
                {
                     rate_map1 = new HashMap<String, String>();

            final String val1 = map_friend.get(j);
            rate_map1.put("friend", val1);
            mylist1.add(rate_map1);
        }

    }

mylist和mylist1是arraylist

Answer 1

如果我理解您的问题，您想知道如何声明地图列表。你可以这样做：

List<Map<String, String>> mylist = new ArrayList<Map<String, String>>();
List<Map<String, String>> mylist1 = new ArrayList<Map<String, String>>();

Answer 2

Android具有HashMap数据结构。请参阅以下代码并获取想法：

ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
list.put("Question=hello", "friend=jack");
