How To Properly Add Data To Arraylist - Android

I have a class the extends arrayAdapter. I am trying to add variables to the list but I am not sure exactly how to do so. Here is my current ArrayAdapter class. class Item {

Solution 1:

That's because you don't have a constructor that matches that signature. Simply make one.

class Item {

     String username;
     String number;
     String content;

     public Item (String username, String number, String content){
     this.username = username;
     this.number = number;
     this.content = content;
     }

}
