I am working on app that uses Navigation pattern. Now I have an Activity and few fragments. Each Fragment has a unique functionality so I created a separate toolbar for each fragment: collapsing, usual or no toolbar at all. I used the following example: https://android.jlelse.eu/instagram-style-navigation-using-navigation-component-854037cf1389
It works pretty well, but now I am taking an issue if I want to set some menu items in the toolbar.
For example, I would like to add a settings menu to the toolbar of the Profile Fragment
I tried setting a menu item, but it simply never appears and I think the method doesn't get called at all..
Is it possible to solve this issue without changing the whole architecture logic?
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
binding = DataBindingUtil.inflate(inflater, R.layout.my_layout, container, false)
setHasOptionsMenu(true)
return binding.root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
binding.toolbar.apply {
setupWithNavController(findNavController())
}
}
override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
inflater.inflate(R.menu.main_menu, menu)
super.onCreateOptionsMenu(menu, inflater)
}
override fun onOptionsItemSelected(item: MenuItem): Boolean {
if(item.itemId == R.id.action_get_info)
Toast.makeText(context!!, "test message", Toast.LENGTH_SHORT).show()
return super.onOptionsItemSelected(item)
}
