I'm trying to set my root LinearLayout element (which is set to fill_parent in both dimensions) to have a background image which is always located in the lower left corner of the screen no matter the orientation of the device. It would be excellent if there were some way to set the background image position such as that which you can do with css using "background-position: left bottom;" but I'm not seeing a way to achieve this in Android. Is there a way to do this?

Thanks for the help.

You'll have to create a custom bitmap drawable with your bitmap in an XML file (eg "res/drawables/my_drawable.xml"

<?xml version="1.0" encoding="utf-8"?>
<bitmap
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/my_png_file"
    android:gravity="bottom|left" />

And then set this drawable xml as your view's background ("@drawables/my_drawable"). The drawable XML format is very poorly documented in the Android site, though, so it's definitely not an easy problem to figure out how to solve on your own.
