How to use Android GradientDrawable

Question

I try to use the GradientDrawable to set a gradient to some backgrounds and buttons. Sadly the documentation is not very detailed.

What are the main attributes to configure the gradient? I understand start and endcolor but some of the other attributes could need some explanation.

At the moment I used images as the background for the buttons but a drawable defined in XML would be much nicer.

I try to get a look like this (It is a very light gradient):

Answer 1

use this xml as background to the imageview.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"&gt;
<gradient android:angle="90" android:startColor="#7c0000" android:endColor="#A71C1C"/>
</shape>

thats it.
