Answer 1

I managed, after a search I discovered the attribute descendantFocusability, and I was testing the values until I found the value afterDescendants.

Listview looked like this in xml, it solved my problem:

<ListView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:id="@android:id/list"
        android:descendantFocusability="afterDescendants"/>

Thank you for the comments.
