Specifying the relative dimension of views in a layout based on device screen width/height

Question

I am writing an android application that has 3 views one below the other. Each view has to be of equal height, depending on the screen size. Each view occupies the full width of the screen. How do you specify in the layout xml that the view has to take up 1/3rd height of the device display height? What would be the appropriate layout to use in this case?

Try android:layout_weight="1"

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<View  
    android:layout_width="fill_parent" 
    android:layout_height="0dp" 
    android:layout_weight="1"
    android:background="#F00"
    />
<View  
    android:layout_width="fill_parent" 
    android:layout_height="0dp" 
    android:layout_weight="1"
    android:background="#0F0"
    />
<View  
    android:layout_width="fill_parent" 
    android:layout_height="0dp" 
    android:layout_weight="1"
    android:background="#00F"
    />
