我的片段事务方法类：

private void showFragment(Fragment fragment) {
    llContainer = (LinearLayout)findViewById(R.id.container);
    if (fragment != null) {
        llContainer.removeAllViewsInLayout();
        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.container,fragment,fragment.getClass().getName());
        fragmentTransaction.commit();
        fragmentManager.popBackStack();
    }
}


@Override
public void onItemSelected(int position) {
    Fragment frag = null;
    switch (position) {
        case POS_HOME:
            frag = FragmentHome.instance(screenTitles[position]);
            break;
        case POS_INBox:
            txtToolbarTitle.setVisibility(View.VISIBLE);
            txtToolbarTitle.setText("Notifications");
            frag = FragmentInBox.instance(screenTitles[position]);
            break;
        case POS_LOG:
            frag = FragmentLog.instance(screenTitles[position]);;
            break;

            frag = FragmentBook.instance(screenTitles[position]);

            frag = FragmentLaws.instance();
            break;
        case POS_DOCUMENT:
            frag = FragmentDocument.instance(screenTitles[position]);
            break;
        case POS_EVENT:
            frag = FragmentEvent.instance(screenTitles[position]);
            break;
        case POS_BOARD:
            frag = FragmentBoard.instance(screenTitles[position]);
            break;
        case POS_AROUND:
            frag = FragmentAround.instance(screenTitles[position]);

        case POS_PROFILE:
            frag = FragmentProfile.instance(screenTitles[position]);
            break;
        case POS_CONCIERGE:
            frag = FragmentConcierge.instance(screenTitles[position]);
            break;
    }

    showFragment(frag);
    mSlideMenu.closeMenu();
