Navigation Component in RecyclerView Adapter

Question

I wrote the following piece of code in the adapter.

holder.itemView.setOnClickListener {
    val action = SearchFragmentDirections.actionSearchFragmentToArtistFragment(artist.id)
    Navigation.createNavigateOnClickListener(action)
}

And this is may navigation xml:

 ...
    <fragment android:id="@+id/searchFragment"
          android:name="com.salmanseifian.spotiny.ui.search.SearchFragment"
          android:label="SearchFragment">

    <action android:id="@+id/action_searchFragment_to_artistFragment"
            app:destination="@id/artistFragment"
            app:popUpTo="@+id/searchFragment"/>
</fragment>

but it won't work. Can anybody help?

Answer 1

You are using lambda which is itself a click listener. Check this Navigation Docs which has proper implementation of click listener using navigation id and createNavigationListener.

Use below code for your case.

holder.itemView.setOnClickListener(
Navigation.createNavigateOnClickListener(R.id.action_searchFragment_to_artistFragment)
)

OR, try this way

holder.itemView.setOnClickListener{ view ->
 view.findNavController().navigate(R.id.action_searchFragment_to_artistFragment)
}
