What should I

Answer 1

Just posting the drawerLayout.closeDrawer() on the message queue using the handler, with a minimal delay solved my problem. Handler.postDelayed() is the key here.

 public void selectItem(int position)
    {
        switch (position)
        {
            case 0:

                DashboardFragment dashboardFragment = new DashboardFragment();
                Bundle args = new Bundle();
                args.putInt(dashboardFragment.ARG_SCREEN_NUMBER, position);
                dashboardFragment.setArguments(args);

                FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

                // Replace whatever is in the fragment_container view with this fragment,
                // and add the transaction to the back stack so the user can navigate back
                transaction.replace(R.id.fragmentLayout, dashboardFragment, TAG_DASHBOARD);
                transaction.addToBackStack(null);

                // Commit the transaction
                transaction.commit();
                getSupportFragmentManager().executePendingTransactions();
                break;            

            default:
                break;

        }

        // Highlight the selected item, update the title, and close the drawer
        drawerList.setItemChecked(position, true);
        setTitle(mScreenTitles[position]);

        mPendingRunnable = new Runnable()
        {
            @Override
            public void run()
            {
                drawerLayout.closeDrawer(GravityCompat.START);
            }
        };
        mHandler.postDelayed(mPendingRunnable,50);

    }
