Recyclerview Doesn't Appear In Fragment

i add a recyclerView to Fragment but it doesn't show any thing in side the fragment i found many questions for the same problem but actually i avoid those errors i Toast messages

Solution 1:

You should call adapter.notifyDataSetChanged() every time you setting new list of data.

Take a look at the documentation.

A good solution would be to create setItems(items) method inside adapter and call notifyDataSetChanged() inside it.

Solution 2:

You need to change

adapter = newStoreListAdapter(v.getContext(), storesList);
storeRecyclerView.setAdapter(adapter);`

to

adapter = newStoreListAdapter(getActivity(), storesList);
storeRecyclerView.setAdapter(adapter);

Solution 3:

Code seems to be ok but i suspect there is a problem with Tablayout. In Main class [where u set the adapter to ViewPager] something link

ViewPager_Adapter_Class  adapter= newViewPager_Adapter_Class (getChildFragmentManager());

I think mistake u made might be here :

use getChildFragmentManager() instead getFragmentManager()

ViewPager_Adapter_Class :

publicclassViewPager_Adapter_ClassextendsFragmentStatePagerAdapter {  
    publicAppLevelMainFragmentAdapter(FragmentManager fm) {
        super(fm);
    }
  .................etc..,
}

Because Tablayout class might be fragment in which ur loading fragments in tablayout .If u use getFragmentManager()/getSupportFragmentManager which basically behaves like activity lifecycle so u need to use getChildFragmentManager(). This is what i suspect hope it will help you.
