Software keyboard move editTexts for android

I'm trying to get the editTexts, and sign in button to move up when the software keyboard is out however I want the background to not be compressed(I'm going to add an image soon). I have the TextView(Login), two EditTexts(email and password) and signin button in a ScrollView because I thought that might help however I have not be able to figure anything out.
