Question

I just started learning android programming and while working through the android Tab Layout tutorial I noticed they created a new Intent with the following code.

// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, ArtistsActivity.class);

Up until now, all the books I’ve read have created a new intent using

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

and was wondering if there is a difference between the two lines of code.

Answer 1

They are equivalent.

Based on the comment from the tutorial…

// Create an Intent to launch an Activity for the tab (to be reused)

It seems they just use the .setClass() method instead of the Constructor that takes a class to be more explicit as the Intent item created there will be reused and .setClass() will probably be called on it again.
