Replacing fragments within viewpager

Question

I am currently having an issue with replacing a certain fragment within ViewPager with another. The fragment id like to replace is my \"Departments\" which has an Imagebutton id

Answer 1

I'm assuming you want the Engineering fragment to be on a completely new page, because you aren't using it in your ViewPagerAdapter. If that's the case, create a new Activity, with your Engineering fragment in the layout, and launch the Activity from the engineeringButton click.

The problem is you are trying to shove your Engineering fragment into the View hierarchy of R.layout.activity_departments, and there is (hopefully) no ViewPager in there, hence the error.
