I am trying to make a list view with two rows and two columns in each
element of the list view. The code I have so far I am trying to
achieve the first task i.e. two rows inside a single list view item. I
saw some online tutorial, and I formed a text view which I inflated in
the java file. It works but it's not exactly what i want, I guess
instead of the last digit which is displayed presently in the list
view, I would like to know how to hard code text 1, text 2, text 3
etc.These text 1 , 2, 3 are basically locations. Is my description
comprehensible?
Here is the updated code.
