java - How to navigate between fragment programatically in android?

Question

Background: I created project by choosing Navigation Drawer template and my MainActivity extends AppCompatActivity.

Problem: I need to traverse/navigate to another UI fragment (lets say FragmentA) for a result on click of a button from UI fragmentB. Something similar to startActivityForResult.

I declared navController as public variable in MainAcitivty and tried to access it in the fragment and execute navController.navigate(MENU_ID); with no luck.

Any suggestion how it can be achieved?

Answer 1

You've to call navigate with either the navigation action id or pass the NavDirections object generated by safeArgs plugin. Here's one article on how to use safeArgs

Safe Args Example

navController.navigate(
    MoviesFragmentDirections.actionMoviesFragmentToMovieDetailFragment(movieId)
)

Action Id Example

navController.navigate(
    R.id.action_movies_fragment_to_movie_detail_fragment
)
