Question

Answer 1

I wanted to implement @nelson-ramirez but had an error accessing mActivity, so this is a combination of those two answers, and works for my project, which uses a tab navigation with Facebook login (which requires support.v4 library). the keys are, creating a private mActivity that you then pass in and assign when initiating the listener, and creating your own Fragment Transaction, not using the one from the argument. Also, change the main activity to FragmentActivity, using v4 library, which allows access to getSupportFragmentManager().

public class MyTabListener implements ActionBar.TabListener{
    private Fragment fragment;
    private FragmentActivity mActivity;

    public MyTabListener(Fragment fragment, FragmentActivity activity){
        this.fragment = fragment;
        this.mActivity = activity;
    }

    @Override
    public void onTabSelected(ActionBar.Tab tab, android.app.FragmentTransaction ft) {
        android.support.v4.app.FragmentTransaction fft = mActivity.getSupportFragmentManager().beginTransaction();
        fft.replace(R.id.fragment_container, fragment);
        fft.commit();
    }

    @Override
    public void onTabUnselected(ActionBar.Tab tab, android.app.FragmentTransaction ft) {
        android.support.v4.app.FragmentTransaction fft = mActivity.getSupportFragmentManager().beginTransaction();
        fft.remove(fragment);
    }

    @Override
    public void onTabReselected(ActionBar.Tab tab, android.app.FragmentTransaction ft) {

    }
}
