Linearlayout for different screen sizes

I have a linearLayout which is surrounded by a scrollView in order to make it for smaller screens scrollable. In the linear layout I have 3 childs which are also linearlayout.

This is working fine. But I also want to support larger screens. At the moment I get with a larger screen space left on the bottom of the screen. I want to have the buttons (navigation bar) be always at the bottom. for larger screens (height) I would like to add at the top of the screen an empty view which fills out the space that is more provided by the larger screen.

How can I achieve that? i tried a lot with weight attribute but didnt get it working.

Here the layout:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="#8db9f6"

Wrap the entire layout in a Relative Layout. Use a relative layout as your root element and set the Linear Layout containing your buttons to layout_alignParentBottom="true" and the ScrollView set to layout_alignParentTop="true".

The LinearLayout containing the buttons and the ScrollView should be direct children of the RelativeLayout.

<RelativeLayout
     android:layout_width="fill_parent"
     android:layout_height="fill_parent">
         <LinearLayout <-- containing the layout minus the buttons
               android:id="@+id/SV"
               android:layout_width="fill_parent"
               android:layout_height="wrap_content"
               android:layout_alignParentTop="true">
            <The Rest Of The Layout>
         </LinearLayout>
         <LinearLayout
               android:id="@+id/LLButtons"
               android:layout_width="fill_parent"
               android:layout_height="wrap_content"
               android:layout_alignParentBottom="true">
          <Buttons>
          </LinearLayout>
</ScrollView>

If you want the buttons to be always at the bottom of the screen alignParentBottom. If you want the buttons to always be at the bottom of the scrollview alignBelow="@id/SV"

android:layout_height="wrap_content" in your inner LinearLayout is your trouble here, changing it to 'fill_parent' should help. In general, you may want to use hierarchyviewer to help troubleshoot layout issues like this.
