Fragment Arguments

Every fragment instance can have a Bundle object attached to it. This bundle contains key-value pairs that work just like the intent extras of an Activity. Each pair is known as an argument.

To create fragment arguments, you first create a Bundle object. Next, you use type-specific “put” methods of Bundle (similar to those of Intent) to add arguments to the bundle.
