如何在導航抽屜打開時禁用viewpager

Question

我已經寫了一個帶有導航抽屜和3個固定選項卡的簡單代碼，但我面對這兩個錯誤 1>即使導航抽屜打開並且當我點擊它時...隱藏在導航抽屜後面的相同位置上的選項卡也會被點擊。 2>當我點擊導航抽屜上的項目時...動作得到執行，但片段並未被viewpager替換或更準確地隱藏。

這裏是代碼.. 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;

    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));

     Toast.makeText(getApplicationContext(), "Search action is selected!", Toast.LENGTH_SHORT).show(); 
     return true;

    return super.onOptionsItemSelected(item);
