I want to populate the textviews dynamically i got everything in the arraylist but my getView method is not getting called.

Answer 1

you are not passing the array of string to the ArrayAdapter.. ArrayAdapter use the passed list to calculate the number of item to display in the view..

Check out the javadoc for ArrayAdapter. You either need to send the array of object to its constructor or call one of the add() method to add the object to the Adapter..
