How to display only one fragment tab in Android

I have different fragments in my MainActivity. In each fragment I implemented some features.
Now I am trying to implemented tabs for one fragments, what I'm looking for is about hide tab layout in remaining fragments.
activity.xml:
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.genworks.oppm.MainActivity">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:id="#+id/activity_search_view_check"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<include layout="#layout/toolbar"/>
<include layout="#layout/search_toolbar"
android:visibility="gone"/>
</RelativeLayout>
<com.google.android.material.tabs.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="scrollable"
app:tabIndicatorColor="#color/White"
app:tabTextColor="#color/White"
android:background="#drawable/button_background"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
app:tabGravity="fill"/>
</com.google.android.material.appbar.AppBarLayout>
<androidx.viewpager.widget.ViewPager
android:id="#+id/viewpager"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>

I think you are asking if we can create two tabs and when the user presses any of the tab, same fragment should appear instead of multiple fragments. If that is your question, may be i can help.
You will have to create one class that extends FragmentStateAdapter , then you should create a single class that extends Fragment instead of having multiple classes and a layout.
Create ClassFragmentPagerAdapter like this:
public class ClassFragmentPagerAdapter extends FragmentStateAdapter {
public ClassFragmentPagerAdapter (#NonNull FragmentManager fragmentManager, #NonNull Lifecycle lifecycle) {
super(fragmentManager, lifecycle);
}
#NonNull
#Override
public Fragment createFragment(int position) {
if (position == 0) {
return new ClassFragment ();
}
return new ClassFragment ();
}
#Override
public int getItemCount() {
return 2;
}
Then after that create the other ClassFragment that extends Fragment:
public class ClassFragment extends Fragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup
container, #Nullable Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View view = inflater.inflate(R.layout.layout_name, container, false);
return view;
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState)
{
super.onViewCreated(view, savedInstanceState);
//do stuff here
}
Hope it helps! Happy coding:)

Navigationdrawer and menu inflater

I changed my App from all Activities to a NavigationDrawer Setup with Fragments. One of my Activities has a menu on top, this is not shown anymore with this new setup. Here is my Code:
Java
public class BurgerMenu extends AppCompatActivity

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_burger_menu);

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
// Check that the activity is using the layout version with
// the fragment_container FrameLayout
if (findViewById(R.id.fragment_container) != null) {
// However, if we're being restored from a previous state,
// then we don't need to do anything and should return or else
// we could end up with overlapping fragments.
if (savedInstanceState != null) {
return;
}
// Create a new Fragment to be placed in the activity layout
LoginFragment firstFragment = new LoginFragment();
// In case this activity was started with special instructions from an
// Intent, pass the Intent's extras to the fragment as arguments
firstFragment.setArguments(getIntent().getExtras());
// Add the fragment to the 'fragment_container' FrameLayout
getSupportFragmentManager().beginTransaction()
.add(R.id.fragment_container, firstFragment).commit();
}
}

The Toolbar from the Navigationdrawer isnt shown with this fragment, neither is the fragments Menu.
Any Solution?

Found the Answer myself, had to change sth. in the XML:
<?xml version="1.0" encoding="utf-8"?>
<StackLayout>
<include layout="#layout/toolbar"/>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</StackLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_burger_menu"
app:menu="#menu/activity_burger_menu_drawer" />

Unable to restore RecyclerView's position/state

Whenever I move from DetailsActivity to MainActivity the RecyclerView is reset and list is always shown from the top position.
Full source code can be seen here. The code is still largely a work in progress.
MainActivityFragment is as follows.
public class MainActivityFragment extends Fragment {

}
}
I have tried setting saving up RecyclerView's state like shown in this post.
I have also tried saving the mArrayList in onSaveInstanceState and restoring it in onActivityCreated or onViewCreated like in this post.
Both of these have not worked for me. As soon as I return back from the DetailsActivity to MainActivity the position is gone.
Thanks.

You're calling a method to update movies list in onStart callback of fragment life cycle. Which means when your main activity is shown back, you're resetting your list. You shouldn't.
You set a new instance of adapter at the end of update list method. That redraws the entire list. You should rethink your life cycles. Call update movie list only in onCreate or onCreateView and always check if adapter opject is null and only then use setAdapter method on recycler view. If adapter is not null, just call notifyDataSetChanged or whatever is needed to update your items.

Maybe this could help. Eventhough it will scroll all the way to the selected item each time.

ActionBar is not showing Title in Android

I want to implement Left & Right Side Slider Menu so I have set Right Side Slider in NavigationDrawerSlider which already have Left Side Slider by Default.
I am using ActionBarSherLock for this to support Application from Api 8. Slider is working fine but issue is that ActionBar is not showing Title.
Please help me to solve this issue. One more thing, When I Click on ImageView, It also fires ActionBarDrawerToggle. So, how to prevent this also ?
My Code:
public class MainActivity extends SherlockFragmentActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList_Left;
private ListView mDrawerList_Right;
private ActionBarDrawerToggle mDrawerToggle;
private ActionBar actionBar_Right;
private ArrayList<NavDrawerItem> navDrawerItems_Left;
private ArrayList<NavDrawerItem> navDrawerItems_Right;
private CharSequence mDrawerTitle_Left;
private CharSequence mTitle_Left;
private CharSequence mDrawerTitle_Right;

I have figured out that It is not showing title because of
actionBar_Right = getSupportActionBar();
actionBar_Right.setCustomView(R.layout.right_menu);
actionBar_Right.setDisplayShowTitleEnabled(true);
actionBar_Right.setDisplayShowCustomEnabled(true);
What to do for this ?

For showing the title in the ActionBar setTitle must be overridden:
#Override
public void setTitle(CharSequence title)
{
this.title = title;
getSupportActionBar().setTitle(title);
}

setIconified(false) force closes my app

Right now I have it not force closing but the keyboard pops up without the search box openning up, like in this picture:
My Search Fragment activity looks like:
public class Search extends Fragment implements SearchView.OnQueryTextListener, ReadJSONResult.OnArticleSelectedListener {
private ListView lv;
View v;
SearchView searchView;
private SearchView mSearchView;
private MenuItem mSearchMenuItem;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//set layout here
v = inflater.inflate(R.layout.activity_search, container, false);
setHasOptionsMenu(true);
getActivity().setTitle("Search");
//get user information
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getActivity());
String userName = prefs.getString("userName", null);
String userID = prefs.getString("userID", null);
//ActionBar actionBar = getActivity().getActionBar();
// Inflate the layout for this fragment
return v;
}
#Override
public void onCreateOptionsMenu (Menu menu, MenuInflater inflater) {
// Inflate the menu; this adds items to the action bar if it is present.
searchView = (SearchView) menu.findItem(R.id.menu_search2).getActionView();
searchView.setOnQueryTextListener(this);
searchView.setIconified(false);
}
public boolean onQueryTextSubmit (String query) {
//toast query
//make json variables to fill
// url to make request
String url = "myURL";
try {
query = URLEncoder.encode(query, "UTF-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String jsonUrl = url + query;
//todo: get json
ReadJSONResult task = new ReadJSONResult(getActivity());
task.setOnArticleSelectedListener(this);
task.execute(jsonUrl);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
// TODO Auto-generated method stub
return false;
}
#Override
public void onArticleSelected(String b, String brewery){
//code to execute on click
Fragment Fragment_one;
FragmentManager man= getFragmentManager();
FragmentTransaction tran = man.beginTransaction();
Fragment_one = new BeerPage();
final Bundle bundle = new Bundle();
bundle.putString("beerIDSent", b);
bundle.putString("breweryIDSent", brewery);
Fragment_one.setArguments(bundle);
tran.replace(R.id.main, Fragment_one);//tran.
tran.addToBackStack(null);
tran.commit();
}
}
my android action bar menu xml is:

looks like here
searchView.setIconified(false);
"searchView" has not been initialized properly yet, because before you create the field, but didn't assign any view for it:
SearchView searchView;
So in your onCreateView you should find your View by Id first before calling methods of searchView:
searchView = (SearchView) findViewById(R.id.the_view_id_here);
