Disable setText of Button Android -

-

i extended button class achieve sign in button of design user cannot change of details or style. after done that, found out can not stop user changing text or design of button either programmatically or xml.

i want achieve sign in button facebook predefined login facebook.

i tried overriding settext no luck, final method can not override

public class signinbutton extends button{     @override     public void settext(charsequence chars){     } }

i suggest not extend button. make view extends view , use ondraw method paint it.

this way view not button developer can't use settext()
