Я пытаюсь добавить NavigationDrawer и ViewPager в моем приложении.

MyActivity - я инициализировал метод Viewpager в onCreate() и метод NavigationItemSelected,
private MenuItem selectedNavMenuItem;
private NavigationView navigationView;
ViewPagerNotificationAdapter pagerAdapter = new ViewPagerNotificationAdapter(getSupportFragmentManager(), fragmentBundle);
viewPager.setAdapter(pagerAdapter);
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
invalidateOptionsMenu();
}
@Override
public void onPageSelected(int position) {
if (selectedNavMenuItem != null)
selectedNavMenuItem.setChecked(false);
else
navigationView.getMenu().getItem(position).setChecked(false);
navigationView.getMenu().getItem(position).setChecked(true);
selectedNavMenuItem = navigationView.getMenu().getItem(position);
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
@Override
public boolean onNavigationItemSelected(MenuItem item) {
try {
selectedNavMenuItem = item;
int intItemID = item.getItemId();
Fragment fragment = null;
Bundle bundle = new Bundle();
actionsToShow = new ArrayList<>();
navigationView.getMenu().findItem(intItemID).setCheckable(true);
if (intItemID == R.id.nav_overview) {
viewPager.setCurrentItem(0);
if (!isWONotif)
actionsToShow = AppSettings.getMenuActionsforNotifications(AppSettings.TabList.Overview);
} else if (intItemID == R.id.nav_items) {
viewPager.setCurrentItem(1);
//fragment = new ItemsFragment();
if (!isWONotif)
actionsToShow = AppSettings.getMenuActionsforNotifications(AppSettings.TabList.Items);
} else if (intItemID == R.id.nav_activities) {
viewPager.setCurrentItem(2);
//fragment = new ActivitiesFragment();
if (!isWONotif)
actionsToShow = AppSettings.getMenuActionsforNotifications(AppSettings.TabList.Activities);
} else if (intItemID == R.id.nav_tasks) {
viewPager.setCurrentItem(3);
//fragment = new TasksFragment();
if (!isWONotif)
actionsToShow = AppSettings.getMenuActionsforNotifications(AppSettings.TabList.Tasks);
} else if (intItemID == R.id.nav_attachments) {
viewPager.setCurrentItem(4);
/*Class fragmentClass = Common.getNextClass(Collections.NOTIFICATION_DOCS_FRAGMENT);
if (fragmentClass == null)
fragmentClass = DocsFragment.class;
fragment = (BaseFragment) Common.getClassInstance(fragmentClass);*/
if (!isWONotif)
actionsToShow = AppSettings.getMenuActionsforNotifications(AppSettings.TabList.Attachments);
} else if (intItemID == R.id.nav_history) {
viewPager.setCurrentItem(5);
/*bundle.putBoolean(Collections.ARG_IS_HISTORY, intItemID == R.id.nav_history);
fragment = new HistoryPendingFragment();*/
if (!isWONotif)
actionsToShow = AppSettings.getMenuActionsforNotifications(null);
}else if(intItemID == R.id.nav_pending){
viewPager.setCurrentItem(6);
/*bundle.putBoolean(Collections.ARG_IS_HISTORY, intItemID == R.id.nav_history);
fragment = new HistoryPendingFragment();*/
if (!isWONotif)
actionsToShow = AppSettings.getMenuActionsforNotifications(null);
}
if (fragment != null) {
hideShowActions();
/*bundle.putBoolean("TwoColumnLayout", false);
bundle.putBoolean(Collections.ARG_IS_WO_NOTIFICATION, isWONotif);
fragment.setArguments(bundle);
getSupportFragmentManager().beginTransaction()
.replace(R.id.notification_detail_container, fragment, "NotificationDetails")
.commit();*/
drawer.closeDrawer(Gravity.LEFT, true);
fragmentsMap.put(intItemID, fragment);
}
} catch (Exception e) {
DliteLogger.WriteLog(this.getClass(), AppSettings.LogLevel.Error, e.getMessage());
}
return true;
}
Ниже мой ViewPagerAdapter класс,
public class ViewPagerNotificationAdapter extends FragmentPagerAdapter {
private final Bundle fragmentBundle;
private boolean isWONotif = false;
public ViewPagerNotificationAdapter(FragmentManager fm, Bundle fragmentBundle) {
super(fm);
this.fragmentBundle = fragmentBundle;
}
@Override
public Fragment getItem(int position) {
isWONotif = (boolean) this.fragmentBundle.get(Collections.ARG_IS_WO_NOTIFICATION);
if(position == 0){
//return new DetailsFragment();
final DetailsFragment df=new DetailsFragment();
this.fragmentBundle.putBoolean(Collections.ARG_IS_WO_NOTIFICATION, isWONotif);
df.setArguments(this.fragmentBundle);
return df;
}else if(position == 1){
//return new ItemsFragment();
final ItemsFragment ifg=new ItemsFragment();
this.fragmentBundle.putBoolean(Collections.ARG_IS_WO_NOTIFICATION, isWONotif);
ifg.setArguments(this.fragmentBundle);
return ifg;
}else if(position == 2){
//return new ActivitiesFragment();
final ActivitiesFragment af=new ActivitiesFragment();
this.fragmentBundle.putBoolean(Collections.ARG_IS_WO_NOTIFICATION, isWONotif);
af.setArguments(this.fragmentBundle);
return af;
}else if(position == 3){
//return new TasksFragment();
final TasksFragment tf=new TasksFragment();
this.fragmentBundle.putBoolean(Collections.ARG_IS_WO_NOTIFICATION, isWONotif);
tf.setArguments(this.fragmentBundle);
return tf;
}else if(position == 4){
/*Class fragmentClass = Common.getNextClass(Collections.NOTIFICATION_DOCS_FRAGMENT);
if (fragmentClass == null)
fragmentClass = DocsFragment.class;
fragment = (BaseFragment) Common.getClassInstance(fragmentClass);*/
return new DocsFragment();
}else if(position == 5){
final HistoryPendingFragment hf=new HistoryPendingFragment();
this.fragmentBundle.putBoolean(Collections.ARG_IS_HISTORY, true);
hf.setArguments(this.fragmentBundle);
return hf;
}else{
final HistoryPendingFragment hf=new HistoryPendingFragment();
this.fragmentBundle.putBoolean(Collections.ARG_IS_HISTORY, false);
hf.setArguments(this.fragmentBundle);
return hf;
}
}
@Override
public int getCount() {
return 7;
}
}
Я работаю на панели навигации и с ViewPager. Viewpager работает,
Я могу видеть NavigationDrawer в фоновом режиме, а также могу скользить NavigationDrawer с ViewPager, но ViewPager занимает весь экран. Я должен показать NavigationDrawer, который отображается в фоновом режиме.
Пожалуйста помоги мне с этим.
Заранее спасибо.
