how to start activity to selected fragment?
this is my fragment list and i need start actvity to topTygodnia() how do it?
val adapter = ViewPageAdapter(supportFragmentManager)
adapter.addFragmenr(Sciana(), "Posty")
adapter.addFragmenr(Wydarzenia(),"Wydarzenia")
adapter.addFragmenr(Konto_zarzadzanie(), "Ustawienia")
adapter.addFragmenr(topTygodnia(), "top tygodnia")
adapter.addFragmenr(TopMiesiaca(), "top miesiaca")
adapter.addFragmenr(OstatnieWiadomosci(), "powiadomień")
viewPager.adapter = adapter
nawigacja.setupWithViewPager(viewPager)
topTygodnia fragment has index of 3 (zero-based index). So you can use ViewPagers currentItem property to set the currently selected page:
viewPager.currentItem = 3
Note: the good approach is to stick to class naming conventions: class name should start with a capital letter, consist of english words and have Camel Case Style. For example use WeekTopFragment instead of topTygodnia, AccountManagementFragment instead of Konto_zarzadzanie.
