Cómo deshabilitar viewpager cuando el panel de navegación está abierto

Question

He escrito un código simple con un cajón de navegación y 3 pestañas fijas, pero estoy frente a estos dos errores 1> Incluso cuando el cajón de navegación está abierto y cuando hago clic en él ... Las pestañas que están presentes en el mismo lugar oculto detrás de la navegación también se hace clic en el cajón. 2> Cuando hago clic en los elementos en el panel de navegación ... la acción se realiza pero el fragmento no se reemplaza ni se oculta con mayor precisión por el visor.

Aquí están los códigos .. MainActivity.java

public class MainActivity extends AppCompatActivity implements FragmentDrawer.FragmentDrawerListener {

private static String TAG = MainActivity.class.getSimpleName();

private Toolbar mToolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
private FragmentDrawer drawerFragment;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mToolbar = (Toolbar) findViewById(R.id.toolbar);

    setSupportActionBar(mToolbar);
    //getSupportActionBar().setDisplayShowHomeEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    drawerFragment = (FragmentDrawer)
            getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
    drawerFragment.setUp(R.id.fragment_navigation_drawer, (DrawerLayout) findViewById(R.id.drawer_layout), mToolbar);
    drawerFragment.setDrawerListener(this);

    // display the first navigation drawer view on app launch
    displayView(0);

    viewPager = (ViewPager) findViewById(R.id.viewpager);
    setupViewPager(viewPager);

    tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(viewPager);
}

private void setupViewPager(ViewPager viewPager){
    ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
    adapter.addFragment(new TabOne(), getString(R.string.tabOne));
    adapter.addFragment(new TabTwo(), getString(R.string.tabTwo));
    adapter.addFragment(new TabThree(), getString(R.string.tabThree));
    viewPager.setAdapter(adapter);
