In order to create a gradient, you create an xml file in res/drawable. I am calling mine my_gradient_drawable.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"> <gradient android:type="linear" android:angle="0" android:startColor="#f6ee19" android:endColor="#115ede" />
</shape>
You set it to the background of some view. For example:
<View android:layout_width="200dp" android:layout_height="100dp" android:background="@drawable/my_gradient_drawable"/>
