Im not getting this layout thingy right.
Here are some pictures to make it easies for me to explain:

That green thing is the temporary icon to the SlidingDrawer. As you see I want it to get the whole way up to the other gray field, so that the gray backgounds becomes one, and the handler icon overlaps the top field.
This is how the xml looks like now:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="bottom"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/info_container"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/drawer_bg"
android:orientation="vertical"
android:paddingBottom="5dip"
android:paddingLeft="10dip"
android:paddingRight="10dip"
android:paddingTop="10dip" >
<TextView
android:id="@+id/info_ip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="10dip"
android:typeface="monospace" />
<TextView
android:id="@+id/info_in"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/wifi_unknown"
android:textSize="10dip"
android:typeface="monospace" />
<TextView
android:id="@+id/info_mo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="10dip"
android:typeface="monospace" />
</LinearLayout>
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1" >
<TextView
android:id="@+id/list_empty"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="center_horizontal"
android:gravity="center_vertical"
android:text="@string/discover_empty"
android:textSize="10dip"
android:typeface="monospace" />
<!-- Slider -->
<SlidingDrawer
android:id="@+id/drawer"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:content="@+id/content"
android:handle="@+id/handle" >
<!-- Image for the handler to the slider -->
<ImageView
android:contentDescription="@string/desc"
android:id="@id/handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/drawer_handle" />
<LinearLayout
android:id="@id/content"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/slider_bg"
android:orientation="vertical" >
<!-- Horisontal layout : wide as possible, but height is minimal -->
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="5dip"
android:orientation="horizontal" >
<!-- Search button -->
<Button
android:id="@+id/btn_discover"
style="@style/ButtonTop"
android:drawableLeft="@drawable/discover"
android:text="@string/btn_discover" />
<!-- Option button -->
<Button
android:id="@+id/btn_options"
style="@style/ButtonTop"
android:drawableLeft="@drawable/settings"
android:text="@string/btn_options" />
</LinearLayout>
<!-- The list with network devices inside the slidingdrawer-->
<ListView
android:id="@+id/output"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:cacheColorHint="#00000000"
android:dividerHeight="0dip" />
</LinearLayout>
</SlidingDrawer>
</FrameLayout>
</LinearLayout>
Ive tried RelativeLayout, but I cant get it right.
Sorry for my bad explanation.
If you want to overlap the info pane with the sliding drawer it too (the info pane layiut) needs to be inside the framelayout.
That simple change should make it work like you want it to.
