如何在ArrayAdapter中使用哈希表中的键和值？_app

概述我有一个带有键,值对的hashmap示例：-(msisdn,值)43664xxxxxxx,243665xxxxxxx,3现在我想在ListView中显示此信息,但我不知道如何将数据从Hashmap馈送到ArrayAdapter？这是我的适配器,请注意,我想将myList替换为哈希映射一个连续的键值.>将上述哈希图传递给适配器,将myList替换为

我有一个带有键,值对的hashmap示例：-

(msisdn,值)

43664xxxxxxx,2
43665xxxxxxx,3

现在我想在ListVIEw中显示此信息,但我不知道
如何将数据从Hashmap馈送到ArrayAdapter？

这是我的适配器,请注意,我想将myList替换为
哈希映射一个连续的键值.

>将上述哈希图传递给适配器,将myList替换为
哈希图

    适配器=新
    ArrayAdapter(this,android.R.layout.simple_List_item_1,myList);
    setlistadapter(adapter);

谢谢
