android xml sample code to define gradient background

android xml defines gradient background

In Android, you can use XML to define gradient backgrounds. Here is a simple example showing how to use shape drawable to create a linear gradient background:

Create a file named gradient_background.xml in the res/drawable directory.

Add the following XML code to define the gradient background:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:andro>
    <gradient
        android:startColor="#FF0000"
        android:endColor="#0000FF"
        android:angle="0" />
</shape>

This XML defines a horizontal gradient from red to blue. android:startColor is the start color of the gradient, android:endColor is the end color of the gradient, android:angle defines the direction of the gradient, 0 means from left to right, and 90 means from top to bottom.

Reference this background in your layout file or style:

&lt;LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/gradient_background"
    android:orientation="vertical"&gt;
    &lt;!-- Other views --&gt;
&lt;/LinearLayout&gt;

In this example, we set the gradient background to the background of LinearLayout. You can apply the background to any view or layout element as you want.
