android - View widthXheight equals to the available space of the screen -


i'm creating layout , have header aligned on top, footer aligned on bottom , want view take rest of available space in middle.

how do without explicit passing height attributes each view?

my actual xml is:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"      android:layout_width="match_parent" android:layout_height="match_parent"      orientation="vertical">       <imageview           android:id="@+id/header"           android:layout_width="match_parent"          android:layout_height="wrap_content"           android:src="@drawable/library_header"          android:scaletype="fitxy" />       <viewflipper           android:id="@+id/content"          android:layout_height="0dip"           android:layout_width="match_parent"          android:layout_weight="1.0" />       <linearlayout           android:layout_width="match_parent"          android:layout_height="44px"           android:layout_alignparentbottom="true"          android:background="@drawable/library_footer">           <button               android:id="@+id/l_coverflow"               android:layout_width="44px"              android:layout_height="34px"               android:background="@drawable/library_coverflow_deselected"              android:layout_gravity="center" android:layout_marginleft="12px" />           <button                android:id="@+id/l_grid"                android:layout_width="36px"               android:layout_height="32px"                android:background="@drawable/library_grid_deselected"               android:layout_marginleft="12px"                android:layout_gravity="center"               android:paddingleft="10px" />           <button                android:id="@+id/l_list"               android:layout_width="40px"               android:layout_height="32px"                android:background="@drawable/library_list_deselected"               android:layout_marginleft="12px"                android:layout_gravity="center" />      </linearlayout> </linearlayout>

it's easy (i omitted android: namespace prefix brevity):

<linearlayout   orientation="vertical"   layout_width="fill_parent"   layout_height="fill_parent">    <!-- header goes here height=wrap_content -->    <middleview     layout_width="fill_parent"     layout_height="0dip"     layout_weight="1.0" />    <!-- footer goes here height=wrap_content -->  </linearlayout>
