What is the difference between this and Activity.this

advertisements

For example

Intent intent = new Intent(this, SecondActivity.class);

eclipse error: The method setClass(Context, Class) in the type Intent is not applicable for the arguments (FirstActivity.ClickEvent, Class)

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);

But that will be correct. Anybody can explain the difference between those two ? Thanks.


this refers to your current object. In your case you must have implemented the intent in an inner class ClickEvent, and thats what it points to.

Activity.this points to the instance of the Activity you are currently in.
