How can i call getItem method on a class if I did not declare it in that particular class. Please also tell me how it works and also for what purpose it is used for.
The above given code is a basic adapter class the allows a class Word containing two strings and one image resource integer variable and their getter methods as well. My intention is to display two text views and one image view in a single list item. The code is fine and the app is also running good.
