Drop shadow for FrameLayout programmatically

Question

Is there a way to add a drop shadow to a FrameLayout programmatically without the use of an additional XML file?

If yes please can you provide me a solution?

Something like that:

Answer 1

I fixed my problem by creating a gradient color on Photoshop, then creating views that has this color as background. On transitions, I change the X,Y,width,height properly :)

Edit 2019:

The simple solution now is add some elevation to the FrameLayout.
