Answer 1

Simply pass view object into onButtonClicked function. getView() does not seem to work as expected inside fragment. Try this code for your FragmentOne fragment

PS. you have redefined object view in your original FragmentOne code.

package com.example.fragmenttutorial;

import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class FragmentOne extends Fragment{

    FragmentManager fragmentManager = getFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_one, container, false);
        onButtonClicked(view);
        return view;
    }

  protected void onButtonClicked(View view)
  {
      if(view.getId() == R.id.buttonSayHi){
          Fragment fragmentTwo = new FragmentTwo();

          fragmentTransaction.replace(R.id.frameLayoutFragmentContainer, fragmentTwo);
          fragmentTransaction.addToBackStack(null);

          fragmentTransaction.commit();   

     }
