could you explain more your issue? And please update the title to provide more information. In Java 'this' refers to the class instance. – Mario Santini Dec 13 '17 at 18:34

So does it mean that in my above case it refers to the object of class MainActivity – Harshal Patil Dec 13 '17 at 18:46

this refers to the object which you are calling the method. When you will create an object, suppose obj and then call obj.onCreate (), this will be a reference to obj.

I get that it refers to the obj. But it looks complex for me in above case.In my question, 'this' refers to MainActivity class ? – Harshal Patil Dec 13 '17 at 18:44

It refers to object and not class. And that object will be an instance of MainActivity – Shiksha Verma Dec 13 '17 at 18:45
