Question

I saw the following code:

 mActionMode = OverviewActivity.this
        .startActionMode(mActionModeCallback);

I saw this here in the Android Dev. tutorial

What is the benefit of calling function like this ? I have changed the code to:

mActionMode = startActionMode(mActionModeCallback);

but, I didn’t see any change.

Answer 1

The difference (if there is any) is that it calls the outer classes method.

class Outer {
   void methodA() { }

   class Inner {
       void methodA() { }

       void method() {
            methodA(); // call my methodA();
            Outer.this.methodA(); // calls the Outer.methodA();
       }
   }
}

It is possible the developer liked to be specific even if he/sge didn’t need to be.
