Changing content of Fragment (Fragment tab) dynamically

Question

I have created a tabbed window using fragments, I have three tabs now in one of the tabs I have a requirement of changing the contents without changing the tab, I searched over and came up with the following:

public class FragmentTab1 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragmenttab1, container, false);


        Button b = (Button)rootView.findViewById(R.id.button1); 
        b.setOnClickListener(on);

        return rootView;



    }
    private View.OnClickListener on = new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            FragmentManager fragmentManager = getFragmentManager();  
            FragmentTransaction fragmentTransaction = fragmentManager  
                    .beginTransaction();  
            Fragment3 fragment3 = new Fragment3();  
            fragmentTransaction.replace(R.layout.fragmenttab1, fragment3);  
            fragmentTransaction.commit();  

        }
    };




}

This is my Main activity:

public class MainActivity extends Activity {
    // Declare Tab Variable
    ActionBar.Tab Tab1, Tab2, Tab3;
    Fragment fragmentTab1 = new FragmentTab1();
    Fragment fragmentTab2 = new FragmentTab2();
    Fragment fragmentTab3 = new FragmentTab3();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ActionBar actionBar = getActionBar();

        // Hide Actionbar Icon
        actionBar.setDisplayShowHomeEnabled(false);

        // Hide Actionbar Title
        actionBar.setDisplayShowTitleEnabled(false);

        // Create Actionbar Tabs
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        // Set Tab Icon and Titles
        Tab1 = actionBar.newTab().setIcon(R.drawable.tab1);
        Tab1 = actionBar.newTab().setText("Reminders");
        //Tab2 = actionBar.newTab().setIcon(R.drawable.tab1);
        Tab2 = actionBar.newTab().setText("Notifications");
        //Tab3 = actionBar.newTab().setIcon(R.drawable.tab1);
        Tab3 = actionBar.newTab().setText("Contacts");

        // Set Tab Listeners
        Tab1.setTabListener(new TabListener(fragmentTab1));
        Tab2.setTabListener(new TabListener(fragmentTab2));
        Tab3.setTabListener(new TabListener(fragmentTab3));

        // Add tabs to actionbar
        actionBar.addTab(Tab1);
        actionBar.addTab(Tab2);
        actionBar.addTab(Tab3);
    }
}

And here is the fragment class:

public class Fragment3 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragmenttab3, container, false);
        return rootView;



    }
}

However when I run this program, I get a strange error:

Any pointers where I might be going wrong?

Hey mate, it works, I had to replace the R.layout with R.id. Craft an answer and I will accept it, now the next task is to add it to back stack :) — Skynet, Dec 04 '13 at 04:02
