What does Class.this mean?

Question

I do understand that Class.this used in case of nested classes but I came across a code which is using it without any nested classes.

// Find the View that shows the numbers category
TextView numbers = (TextView) findViewById(R.id.numbers);

// Set a click listener on that View
numbers.setOnClickListener(new View.OnClickListener() {
   // The code in this method will be executed when the numbers View is clicked on.
   @Override
   public void onClick(View view) {
       Intent numbersIntent = new Intent(MainActivity.this, NumbersActivity.class);
       startActivity(numbersIntent);
   }
});

In the line:

 Intent numbersIntent = new Intent(MainActivity.this, NumbersActivity.class);

Why is MainActivity.this used and why can't we use this.

if you use `this` there then you are referring to anonymous class not `MainActivity` — Pavneet_Singh, Jan 04 '17 at 06:21

Because here new View.OnClickListener() is anonymous inner class.
