Question

Modify the following code so that it includes a button when clicked it changes the layout from relative to linear.

Also, add an image that when clicked it enlarge to view better for the user.

** I couldn't find "ic_btn_speak_now" in application files I think it is located in android resources. I think you can refer to it the way it is written.

** You can replace the photo if you wish with any appropriate photo, I just need to see how it clicked an englarge.

Thanks for your help in advance.
