How to create a new Button shape in Android

Basically android give us the by default Button icon,which does not seems to look professional,so in order to make it look more attractive,we have to create a new XML file specially for its shape.So you need to follow the below steps:

Firstly right click on 'res' folder and create a new Android XML file,name it shape.
Now right the following code in your Shape.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >

<corners
android:radius="15dp"
/>
<gradient
android:angle="45"
android:centerX="35%"
android:centerColor="#1E90FF"
android:startColor="#000000"
android:endColor="#000000"
android:type="linear"
/>
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp"
/>
<size
android:width="150dp"
android:height="40dp"
/>
<stroke
android:width="3dp"
android:color="#878787"
/>
</shape>

3.Now we have to link this file with the background of our button,so we simply write this code:

android:background="@drawable/shape"

4.Now we are done with changing the look of our button,compare the shapes of button,now and before:
