How to create a shadow that contains colour with a feather effect?

I have been searching around the interwebs for a way to create a glow/shadow effect for my ImageView inside android. I have attached a file with a concept that I created; under each theme card you can see a feathered glow effect that is the same colour as the card itself.

Would anyone that stumbled across this post know of a way to accomplish this? I have tried "layer-list" and it does somewhat of a job but doesn't contain a glow or a feather.

Any assistance would help, thanks.

Try this:

• This type of shadow I get the best results by using a 9 patch images shadow.
• You can use this link 9 patch image shadow editor

i hope it helps you.
