    };
    public Favorite() {
        // Required empty public constructor
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment

        initializeVariables();
        return parent;
    }

    private void addFragmentToTablayout()
    {
    try
    {

        objectFavoriteStatusTabAdapter.addFragments(objectFavoriteTextStatusFragment);

        objectFavoriteStatusTabAdapter.addFragments(objectFavoriteImageStatusFragment);
        objectViewPager.setAdapter(objectFavoriteStatusTabAdapter);


        objectTablayout.(objectViewPager);
        objectViewPager.setSaveFromParentEnabled(false);

    }
    catch (Exception e)
    {
        Toast.makeText(getContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
    }
    }


    private void initializeVariables()
    {
        try
        {
            objectFavoriteTextStatusFragment=new favoriteTextStatusFragment();
            objectFavoriteImageStatusFragment=new favoriteImageStatusFragment();

            objectTablayout=parent.findViewById(R.id.favoriteFragment_TabLayout);

            objectViewPager=parent.findViewById(R.id.favoriteFragment_viewPager);
        }
        catch (Exception e)
        {
            Toast.makeText(getContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
            
        }
    }
}

is there any alternative way to access setupWithViewPager or how should i access it.

Answer 1

It seems that you are confusing xml using TabLayout and Java code you use TableLayout. Modify TableLayoutOut in Java Code and Running, your problem has been solved

public class Favorite extends Fragment {


//XML Variables
private View parent;
private TabLayout objectTablayout;
private ViewPager objectViewPager;

//Class Variables
favoriteImageStatusFragment objectFavoriteImageStatusFragment;
FavoriteStatusTabAdapter objectFavoriteStatusTabAdapter;
favoriteTextStatusFragment objectFavoriteTextStatusFragment;

private int[] tabIcons= {
        R.drawable.ic_text, R.drawable.ic_image
};
public Favorite() {
    // Required empty public constructor
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    parent= inflater.inflate(R.layout.fragment_favorite, container, false);
    initializeVariables();
    return parent;
}

private void addFragmentToTablayout()
{
try
{
    objectFavoriteStatusTabAdapter=new FavoriteStatusTabAdapter(getChildFragmentManager());
    objectFavoriteStatusTabAdapter.addFragments(objectFavoriteTextStatusFragment);

    objectFavoriteStatusTabAdapter.addFragments(objectFavoriteImageStatusFragment);
    objectViewPager.setAdapter(objectFavoriteStatusTabAdapter);


    objectTablayout.(objectViewPager);
    objectViewPager.setSaveFromParentEnabled(false);

}
catch (Exception e)
{
    Toast.makeText(getContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
}
}


private void initializeVariables()
{
    try
    {
        objectFavoriteTextStatusFragment=new favoriteTextStatusFragment();
        objectFavoriteImageStatusFragment=new favoriteImageStatusFragment();

        objectTablayout=parent.findViewById(R.id.favoriteFragment_TabLayout);

        objectViewPager=parent.findViewById(R.id.favoriteFragment_viewPager);
    }
    catch (Exception e)
    {
        Toast.makeText(getContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
        
    }
}

}
