Anyone know how to do this?

You can simply make an XML Drawable, something like this (save under res/drawable):

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    <gradient
        android:angle="0"
        android:type="linear"
        android:startColor="#FF00FF00"
        android:endColor="#FFFFFFFF"
        />
    <stroke
        android:width="1dp"
        android:color="#FF000000"
        />
/>

then just use a TextView, with this Drawable set as your android:background attribute.

Do you want the colour to dynamically change colour for each value? Or are you okay with just having a few colour "levels" (e.g. red, yellow, green).

The easier route would be to just have a few set colours and create those gradients in photoshop and then apply those textures to the back of an ImageView using the background attribute.
