Switch between tab navigation and list navigation

I use ActionBarSherlock and use this template to navigate the tab that I found on the Android developer site. It works very well, but I also want to switch between NAVIGATION_MODE_TABSand NAVIGATION_MODE_LISTwhile maintaining the connection between tabs and fragments.

The template mentioned above is pretty good for maintaining common code. Therefore, I add listeners to my tabs and associate them with snippets such as this:

bar.addTab(bar.newTab()
.setText("MyFragment")
.setTabListener(new TabListener<SomeFragment>(this, "myfargment", SomeFragment.class)));

and create an instance of the fragment by clicking on the corresponding tab using generics:

public void onTabSelected(Tab tab, FragmentTransaction ft) {
    if (mFragment == null) {
        mFragment = Fragment.instantiate(mActivity, mClass.getName(), mArgs);
        ft.add(android.R.id.content, mFragment, mTag);
    } else {
        ft.attach(mFragment);
    }
}

- :

@Override
public boolean onNavigationItemSelected(int itemPosition, long itemId) {
    switch (itemPosition) {
    case 0:
    //Replace the current fragment with FragmentA
        break;
    case 1:
    //Replace the current fragment with FragmentB
        break;
    case 2:
    //Replace the current fragment with FragmentC
        break;
    default:
        break;
    }
    return true;
}
