Post your logcat output and the part of your layout xml file where you
declare the RelativeLayout.
I would guess that you either didn't assign an android:id to the
relative layout, or using the wrong id with findViewById. Because of
this, the value of "background" is null.

Hi everyone.
I have a relative layout that I want to change the background
according to a set of features. For some reason when I try to change
the background image I get a null pointer exception. Currently in the
onStart method I call a function the handles valedating then determins
what background image should show. The code for the image change I
have is below:
RelativeLayout background =
(RelativeLayout)findViewById(R.id.currentWeatherBackground);
background.setBackgroundResource(R.drawable.blue_background);
blue_background is in my resource folder and I can use it just fine if
I type it into the XML.
Could anyone please shed some light on what I am doing wrong?
Thank you for your time and help,
Tommy
