Question

I want to create a ListView with alternating row layouts.

Row 1 - Layout A
Row 2 - Layout B
Row 3 - Layout A etc.

Is it necessary to create a Custom Adapter for that or is it by default possible?

Answer 1

No you can’t do this without Adapter, but look at getViewTypeCount() and getItemViewType(postion) of the BaseAdapter class, as they will support you.

First let your Adapter know how much different types your rows have; in your case they are 2 (Layout A, and Layout B).

The second method returns the type for the given position. In your case it could be something easy like the following code.

@Override
public int getItemViewType(int postion){
    return (postion % 2);
