How to give Fixed width and height for Button in Android

Im beginner in android development. I ve just created a button in main.xml file

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >



  <Button 
    android:text="Click"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    />

I just give integer value for android: but I got error error: Error: Integer types not allowed

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.

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"
    />
