[android] Dove inserire la logica

[Maxton]

Ciao a tutti, scusate la mia ignoranza ma sono nuovo. Ho creato una applicazione con lo swipe + tabs, quindi la mainActivity in realtà è un fragment activity, ho creato una scheda con i vari bottoni, ma non riesco a inserirci una logica all'interno. Mi spiego meglio, il tab in questione ha dei bottoni "aprire connessione", e "chiudi connessione", ma non so dove inserire la banalissima logica di programmazione all'interno del fragmentActivity. Confermo che le poche righe di codice che ho creato funzionano in una semplice Activity, vi posto il codice

Questo è il main

public class MainActivity extends FragmentActivity implements ActionBar.TabListener
{
    private static Socket socket = new Socket();
    private static DataOutputStream outToServer = null;
    private static String ip = "192.168.50.104";
    private static int port = 2000;

    SectionsPagerAdapter mSectionsPagerAdapter;
    
    ViewPager mViewPager;


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

        final ActionBar actionBar = getActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        mSectionsPagerAdapter = new SectionsPagerAdapter(
                getSupportFragmentManager());

        mViewPager = (ViewPager) findViewById(R.id.pager);
        mViewPager.setAdapter(mSectionsPagerAdapter);
        
        mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() 
                {
                    @Override
                    public void onPageSelected(int position) 
                    {
                        actionBar.setSelectedNavigationItem(position);
                    }
                });

        for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++)
        {

            actionBar.addTab(actionBar.newTab()
                    .setText(mSectionsPagerAdapter.getPageTitle(i))
                    .setTabListener(this));
        }    
        setContentView(R.layout.activity_connection);
    }
    
    @Override
    public boolean onCreateOptionsMenu(Menu menu)
    {
        getMenuInflater().inflate(R.menu.main, menu);
        getMenuInflater().inflate(R.menu.connection, menu);
        return true;
    }
    
    
    @Override
      public boolean onOptionsItemSelected(MenuItem item)
    {
        return super.onOptionsItemSelected(item);
    }
    
    
    @Override
    public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction)
    {
        mViewPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction)
    {
        
    }

mi rendo conto che è un problema sciocco, ma questi fragment non so proprio trattarli...
