I\'m always using onclick() event in most of my projects. But, I read about OnClickListener(). Can anyone tell what\'s the difference between these
I'm not sure the question is clear. View.OnClickListener is an interface, which defines the onClick(View) method. If you have a class which intends to listen for clicks, you should both implement the interface (if not already extending a class that does), and implement this method too. You have to use both; they're not somehow alternatives.
