Hello!

I just can't display the button at the bottom of the screen. I have 2 textviews and 2 edittexts set as gone, and they become visible when user clicks checkbox. It's only then that my button gets positioned properly Otherwise it sits on top of the app at launch of my app.(see here: http://www.shrani.si/f/3V/10G/4nnH4DtV/layoutproblem.png) I also tried android:layout_alignParentBottom="true" but that doesnt help either.

 <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/scrollview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
