How do i create a simple expandable list in android

i want to make an expandable list in android ( with only one group ) that has item1, sub-item1, seperator, item2, sub-item2, sperator and so on..., where item1 and item2's values are taken from an array of numbers and sub-item1 and sub-item2's values are taken from an array of strings. I did att开发者_高级运维empt to find out but im pretty new and dont understand most of it(yet):D.

Thanks in advance.
