Because that's what you coded.

Let's create a button with a (@Deprecated) ClickListener.
On first iteration, dismissListener hasn't been initialized, so it has
its default value: null.

Now that the button is created and "used", let's create a
ClickListener for the current Info, but don't use it.
On first iteration, this sets dismissListener from 'null' to a
ClickListener for the first row (but notice that the button has been
created with a null listener, and added the first row already; so this
listener will only be used on second iteration, so that the second
button's listener will be related to the first Info, and so on for
other rows)
