public class MyPagerAdapter extends FragmentStatePagerAdapter {
    private String[] fragmentContents;

    public MyPagerAdapter(FragmentManager fm, String[] contents) {
        super(fm);
        fragmentContents = contents;
    }

    @Override
    public Fragment getItem(int position) {
        MyFragment fragment = new MyFragment();
        Bundle args = new Bundle();
        args.putString("toastMessage", fragmentContents[position]);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public int getCount() {
        return fragmentContents.length;
    }
}

public class MyFragment extends Fragment {
    private String toastMessage;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            toastMessage = getArguments().getString("toastMessage");
        }
    }

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

        // Show the Toast message
        Toast.makeText(getActivity(), toastMessage, Toast.LENGTH_SHORT).show();

        return view;
    }
}
