Adding layout to the bottom of screen in Android -

i want add layout this:

    <header layout>(fixed)          |          |      <scrollview>          |          |     <footer layout>(fixed) 

here's i've tried far:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent" >      <scrollview         android:id="@+id/container"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:layout_above="@id/footer" >          <linearlayout             android:id="@+id/limain"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:orientation="vertical" >         </linearlayout>     </scrollview>    </relativelayout> 

this question possible duplicate of this

remember header part missing in above example can declare like

 <linearlayout    android:id="@+id/header"     android:layout_width="match_parent"    android:layout_height="wrap_content"    android:layout_alignparenttop="true"    android:weightsum="1"    android:gravity="center" >    <button             android:id="@+id/button_show_header"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_weight="1"             android:text="header." />       </linearlayout> 

nd in scrollview put 1 line

 android:layout_below="@id/header" >
