Updating Layout When Navigating to Fragment

Updating Layout When Navigating to Fragment

Nathan Sokalski 4,111

When navigating to a Fragment using the SupportFragmentManager in .NET for Android using code similar to the following:

this.SupportFragmentManager.BeginTransaction().DisallowAddToBackStack().Replace(Resource.Id.fcvMain, new ScoresFragment()).Commit();

Many of the RecyclerView(s) on the Fragment I am navigating to are not displayed. I have confirmed that the LayoutManager(s) & Adapter(s) for the RecyclerView(s) have been set, and that they all have data. I do this in the OnResume method of the AndroidX.Fragment.App.Fragment that contains the RecyclerView(s). I also call the NotifyDataSetChanged() method of the Adapter of each RecyclerView I have also tried creating simple FrameLayout(s) with solid backgrounds & fixed sizes as placeholders, but I could not get them to display either. The root of my Fragment's layout is a 2×5 GridLayout. Why are so many of the child View(s) (including the FrameLayout(s) I mentioned as using for testing) not displayed?

Are there any relative logs for this problem? How can we reproduce this problem? Could you please post more code snippets or a basic demo so that we can try to reproduce this problem on our side?

You can try these fixes:

1.      Do initialization in OnViewCreated() instead of OnResume()

OnResume() might be too late for some layout-related updates.

Fix:

Move RecyclerView setup(Adapter, LayoutManager etc.) to OnViewCreated():

Public override void OnViewCreated(View view, Bundle savedInstanceState)

{

                Base.OnViewCreated(view, savedInstanceState);

                recyclerView = view.FindViewById<TecyclerView>(Resounse.Id.myRecyclerView);

                recyclerView.SetLayoutManager(new LinearLayoutManager(Contaxt));

                recyclerView.SetAdapter(myAdapter);

2.      Check Fragment Layout inflation

Ensure you’re inflating the correct layout in OnCreateView();

Public override View OnCreateView (LayoutInflater inflater, ViewGroup container, Bundle sabedInstanceState)

{

Return inflater.Inflate(Resouce.Layout.fragment_scores, container, false);

}

If you are returning null or inflating incorrectly, the layout won’t show.

3.      Use ChildFragmenrManager if you are nesting Fragments

Use ChildFragmenrManage instead of SupportFragmentManager.

4.      Check Parent Container View(fcvMain)

Ensure fcvMain (container in Replace()) exists in the current activity layout and has:

·         Android:id = “@+id/fcvMain”

·         A valid height/width (match_parent is safe)

·         It is not inside another Fragment that is not attached yet

5.      Check GridLayout behavior

If you are using a GridLayout as the root of your fragment make sure it has proper layout parameters(match_parent) and it is better to use ConstraintLayout or LinearLayout as root if layout is not rendering properly.

Hope this helps . please let me know if you have any other query
