In Slide Menu Control With Tab View Giving Tabs Empty In Android Studio

Actually, I'm working one app that app has side menu drawer and in a home page, tab view is there.
In that menu have 5 fragments let's say
HomeFragment
PhotosFragment
NotificationsFragment
These are in menu and in home fragment, two tabs are like recent tab and all tab
so now I'm going to say what happened, menu control and tab control working without bug but whenever app starting time only.
I mean see now app started by default it shows home fragment, in that home fragment I said know 2 tabs are there.So those are working but now coming to point what was the bug.
If I select another menu item to let's say Photos Fragment then after again I select Home Fragment those tabs are not showing.
I mean whenever app starts the first time its showing tabs after that not showing.
Why its coming like this really I don't know I checked lot ways.
this is my code

Is There any Possible to Achieve Use SlideMenu With TabView In Android Studio

Actually i'm designing one app now.
Slide menu control, this menu have 5 categories like 5 fragments.
Each fragment have different different datas.I implemented slide menu also working perfectly.
Here first fragment is home fragment,In that i need to use tab swipe view control i mean two tabs will be there like tab names recent and all tabs.
So when i press recent tab needs to show something and when i press all tab needs to show something.
But here i don't know how to use i researched for lot but i didn't get those.
What i exactly need is in slide menu home fragment i need tab based fragment
For your reference this screen shot
I need those codes please.And let me know is it possible or not.
Thanks in advance
this is my home fragment
public class HomeFragment extends Fragment {
View view;
private TabLayout tabLayout;
private ViewPager viewPager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
view = inflater.inflate(R.layout.fragment_home, container, false);
viewPager = (ViewPager) view.findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) view.findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
return view;
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new
ViewPagerAdapter(getFragmentManager());
adapter.addFragment(new MoviesFragment(), "ONE");
adapter.addFragment(new PhotosFragment(), "TWO");
adapter.addFragment(new SettingsFragment(), "THREE");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
These Fragments are for tab
adapter.addFragment(new MoviesFragment(), "ONE");
adapter.addFragment(new PhotosFragment(), "TWO");
adapter.addFragment(new SettingsFragment(), "THREE");
all are just empty fragments..thanks in advance

java.lang.ArrayIndexOutOfBoundsException: length=5; index=5?
Looks like Exception happens when you call:
getSupportActionBar().setTitle(activityTitles[navItemIndex]);
navItemIndex has range from 0 to 5 (a.e. length 6) when activityTitles has only 5 items
Solution:
Set 6 items for activityTitles

Fragment doesn't change after item click Navigation Drawer

I'm building an app which contains a NavigationDrawer to navigate between Fragments.
For some reason, when pressing on any item in the Navigation Drawer the item just marks itself and doesn't change the fragment (tried debug but the item clicks doesn't calls the functions)
The fragment is not loading in first click..i have to press twice to reload the fragment

There are couple of problems with the code:
Make sure u add break in switch:
case R.id.nav_about_us:
startActivity(new Intent(MainActivity.this, AboutUsActivity.class));
drawer.closeDrawers();
break; //add break
case R.id.nav_terms:
startActivity(new Intent(MainActivity.this, TermsActivity.class));
drawer.closeDrawers();
break;
default:
navItemIndex = 0;
break;
Also your fragment not loading as you are not calling the function properly:
in your Switch case:
case R.id.nav_home:
navItemIndex = 0;
CURRENT_TAG = TAG_HOME;
Fragment fragment = getHomeFragment(); //get fragment based on index
ReplaceFragment(fragment); //now replace them and load new one
drawer.closeDrawers();
break;
in ReplaceFragment method write:
public void ReplaceFragment(Fragment r_fragment) {
if (r_fragment != null) {
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame, r_fragment).commit();
} else {
// error in creating fragment
}
}
Also overWrite following methods:
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
drawerView.bringToFront(); //add this two lines
drawerView.requestLayout();
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
actionBarDrawerToggle.syncState();
}

To add the Tablayout with NavigationDrawer :
1.create a new File “TabFragment.java” to inflate & code TabLayout and viewPager elements.
2.For viewPager to display content it requires a Adapter . use a FragmentPagerAdapter which is used to inflate tab specific fragments.
3.The FragmentPagerAdapter overrides three main methods :
a) getCount() : It returns the total number of tabs to be bind with the view pager.
b) getItem(int position) : It returns the tab-specific fragment wrt to its position.
c) getPageTitle(int position)` : It returns name of the title according to the position
4.At the end , attach your ViewPager with the TabLayout with the setupWithViewPager(viewPager) method of the TabLayout .
Here is a detail implementation: https://androidbelieve.com/navigation-drawer-with-swipe-tabs-using-design-support-library/
Hope it helps.
As u are using toolbar you can use:
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
//Checking if the item is in checked state or not, if not make it in checked state
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
case R.id.first:
toolbar.setTitle("First Item");
return true;
case R.id.second:
toolbar.setTitle("Second Item");
return true;
}
}
to set title..during click on fragments
