[android-developers] customAdapter how to print out content of array in TextView.setText() of getview

Hi,

I have written a CustomAdapter to display a list of hash key+value
items as a list. But I am stuck on the line below.

label.setText(my_VALUES[0])

Class two is my CustomAdapter and I am passing it a hashMap

public MyCustomAdapter(DynamicLists dynamicLists, int row,
HashMap<String,String> data)

here I combine key+value pairs and I assign them to an array called
my_VALUES. But I don't know if this is correct?

How can I print out each KEY+VALUE pair as a seperate item in getview.
at the moment I can only use label.setText(my_VALUES[0])

Thanks

graham
