Drawing animation in Android

Drawing graphics directly using XML

We can also draw graphics in android using XML .

First i need to create a blank project called "Drawing"

Then make a new  file inside the drawable folder called rect.xml.

Creating a new xml file 

I write this codes inside my rect.xml:

<shape xmlns:android="http://schemas.android.com/apk/res/android"

    android:shape="rectangle">

    <gradient

        android:startColor="#FFFF0000"

        android:endColor="#80FF00FF"

        android:angle="45"/>

    <padding

        android:left="7dp"

        android:right="7dp"

        android:top="7dp"

        android:bottom="7dp"/>

    <corners android:radius="10dp"/>

    </shape>

Animation.xml

Now drag a button in activity.main.xml file and i need to apply the rect.xml feature in my button.

this is done by changing  the background of button :

android:background="@drawable/rec"

Adding  drawing animation in button

And the button looks like this:
