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

The ListView looks like this in xml, this solved my problem:

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

Thanks for the comments.
