import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
import android.widget.ArrayAdapter;

public class mainMenu extends ActionBarActivity implements ActionBar.OnNavigationListener {

    ActionBar actionbar;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.menutab);

        actionbar = getSupportActionBar();

        actionbar.setListNavigationCallbacks(mSpinnerAdapter, this);
    }

    @Override
    public boolean onNavigationItemSelected(int arg0, long arg1)//item pos, itemid
    {
        switch (arg0) {
