Answer 1

There can be a couple of ways. It would nice if you add some code for the reference. 1st way would be to have a method in the fragment which would have the set the visibility to gone in fragment. In you activity you can get the instance of the fragment by this getSupportFragmentManager().findFragmentById(<container - id>) and then just call the fragment method.

2nd way could be using interface to this.
