here have tried following code change colour of button when button clicked not hold colour when go , return button , work events

yesbtn.setbackgroundcolor(color.yellow); nobtn.setbackgroundcolor(color.blue); maybebtn.setbackgroundcolor(color.blue); 

the above mentioned code under yesbtn.onclicllistener() method

here how use shared preference solve issue

you can store color in shared preference int. suggestion , need not store color , flag value 1,2,3,etc , based on value can set color on button
