To create a button with fixed height and width, you can give values in both px or in dp.

giving values in dp is more convenient , bec android automatically scale the height and width in ldpi,mdpi and hdpi devices.

<Button 
    android:text="Click"
    android:layout_width="100dp"
    android:layout_height="50dp"
    />

What is the difference between android:layout_width and android:width

You need to give Numeric Values as following,

 <Button 
    android:text="Click"
    android:layout_width="250dp"
    android:layout_height="50dp" />

use integer(25, 40 ...) + type(DP,DIP,PX) :like

android:layout_width="25dp"

Why you want to do it . better use wrap content, or use weight tag, so it will support and will look good on all sizes devices.
