application blank after move to another fragment using bottom navigation view

I tried to build an app that have 5 fragment that displayed using bottom navigation view. I use volley to get the data from database. i have a problem with calling the data. at fragment A. i call the web service and got some data and then display it using recyclerview. But if i move to another fragment ( lets say fragment B) and went back to the fragment A. the data is lost and it just show the standard ui like search widget,spinner widget. All i want to ask is :
where should i put the code to call web service for all my fragment. On the activity that handle the fragment or just on the fragment?
why volley doesn't call data again when i back to the fragment?
this is the code of my mainactivity that contain bottom navigation view with 5 fragments:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(isNetworkStatusAvialable (getApplicationContext())) {
bottomNavigationView=(BottomNavigationView)findViewById(R.id.main_nav);
frameLayout=(FrameLayout) findViewById(R.id.main_frame);
herbal= new herbal();
crude = new crude();
database=new database();
analysis=new analysis();
compound=new compound();
setFragment(herbal);
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId())
{
case R.id.nav_herbal:
setFragment(herbal);
return true;
case R.id.nav_crude:
setFragment(crude);
return true;
case R.id.nav_database:
setFragment(database);
return true;
case R.id.nav_analysis:
setFragment(analysis);
return true;
case R.id.nav_compound:
setFragment(compound);
return true;
default:
return false;
}
}
});
} else {
Toast.makeText(getApplicationContext(), "internet is not avialable", Toast.LENGTH_SHORT).show();
}
}
private boolean isNetworkStatusAvialable(Context context) {
ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivityManager != null)
{
NetworkInfo netInfos = connectivityManager.getActiveNetworkInfo();
if(netInfos != null)
if(netInfos.isConnected())
return true;
}
return false;
}
private void setFragment(Fragment fragment) {
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.main_frame,fragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
this is the example in my fragment which calling web service and then display it using recycler view:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_herbal, container, false);
herbalModels = new ArrayList<>();

move your data code in separate class and call it wherever needed.

Recycler view swaps items when i scroll them

I am developing the chatbot app. I am using the RecycleView to render the chat of user and bot. I have to show the user listview or text response depend upon his query. All is working until my RecyclerView get's scroll. Whenever my RecyclerView gets scroll it changes the item position. I search a lot and applied every solution but not able to solve my issue.

But when i'm viewing this it in layout as this order
adding measure data value ________________22222.0
adding measure data value ________________11111.0

Hi I have done a mistake in addview method. Before my addview method is
mDisplayContainer.addView(view, mDisplayContainer.getChildCount() - 1);
Now i changed
mDisplayContainer.addView(view);
Its Working for me. Thank u so much for your comments

Not getting the correct data on clicking the LISTVIEW

I have 3 list in my fragment i.e. list 1,list2 and list3. And all are interdependent.I'm using AsyncTask for showing these list.
When i click on list 1 its shows some data on list 3 and so on when i clik on list 2 it shows data on list3.
Now the problem is there is a next button,if i don't click on list 2 and press next it does not show the correct data.
list 2 returns null and thus does not functional correct.
Below is the code
