android webview layout to take remaining space

Question

I want to create, what seems to be a simple layout, but I am having a few problems with it. The layout consists of a header, body which is a webview, and a footer banner on bottom as seen on the attached sketch.

I need the webview to take all the remaining space between the header and footer.

I have tried this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical"
 android:background="@drawable/back"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent">
 <ImageView  
android:id="@+id/banner"
     android:layout_height="wrap_content"
     android:layout_width="wrap_content" 
     android:src="@drawable/banner" /> 
<WebView  
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/bck"
    android:layout_weight="2"
    android:layout_gravity="center"/>
  <RelativeLayout   
     android:layout_width="wrap_content"   
     android:layout_height="wrap_content"
     android:layout_weight="4"> 
        <com.mobclix.android.sdk.MobclixMMABannerXLAdView 
                android:id="@+id/banner_adview"
                android:layout_width="320dip"
                android:layout_height="50dip"
                android:layout_gravity="center"
                android:layout_alignParentBottom="true" />
   </RelativeLayout>

Answer 1

Put all of them inside a RelativeLayout and in the webview use layout_below="@id/header_banner" and layout_above="@+id/footer_banner"
