Unable to make CustomAdapter work in a Loop using Fragments

I'm trying to fill make the data show in my Listview, however when i click on the fragment there is nothing on the list.
I've tried move the setAdapter inside the loop but it did not work.
I'm running out of ideas about how to make it work
Has anybody tried to fill an custom adapter with fragments before???
This is my Custom Adapter

public class MyListAdapter extends ArrayAdapter<User> {
List<User> userList;
Context context;
int resource;
public MyListAdapter(#NonNull Context context, #LayoutRes int resource, List<User> userList) {
super(context, resource, userList);
this.context = context;
this.resource = resource;
this.userList = userList;
}
#NonNull
#Override
public View getView(final int position, #Nullable View convertView, #NonNull ViewGroup parent) {
//And for this we need a layoutinflater
LayoutInflater layoutInflater = LayoutInflater.from(context);
Log.d("listando", "Antes do inflater");
//getting the view
View view = layoutInflater.inflate(resource, null, false);
Log.d("listando", "Depois do inflater");
//getting the view elements of the list from the view
TextView textViewName = view.findViewById(R.id.list_row);
Log.d("listando", "Depois de pegar o textview");
//getting the hero of the specified position
User user = userList.get(position);
Log.d("listando", "Depois de pegar o get pisition");
//adding values to the list item
textViewName.setText(user.getName());
Log.d("listando", "Depois de setar o name");
//finally returning the view
return view;

What i have noticed is that the logs inside the adapter are not showing

When you create adapter
MyListAdapter adapter = new MyListAdapter(getContext(), R.layout.my_list, userList);
the userList is empty. So when you add an item to userList, you have to adapter.notifyDataSetChange() to update your adapter

Try refMessages.addChildEventListener(getActivity(),new ChildEventListener() {......}
Do this in every listeners if they are in fragments.
In case of an Activity you don't need to do this.

startActivity method is not working in my listview onitemclicklistener

I checked all the previous questions regarding this issue, but none of them are helpful to me.
I am trying to open new activity in my listview onItemClickListener but it is not opening the new activity. In the android monitor, it shows
"D/ViewRootImpl: ViewPostImeInputStage ACTION_DOWN".
The onItemClickListener is not responding when I click that item of my listview... Is it possible to open?
The activity is successfully running, but I am unable to listen for list click events.
How to correct this?

If there are clickable UI elements like Button, Imagebutton are present in child view of list/Recyclerview, they can take control of click events. So, Recyclerview would not get chance to click event.
Please set android:focusable="false" for all child clickable view. Then your itemclick will work.
You can also use following property in parent view that prevent child view getting focus.
android:descendantFocusability="blocksDescendants"

You implement wrong method of list item click listener, just replace this
enquiry_listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
}
To:
enquiry_listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {}}

AsyncTask is not functioning on my second fragment connected to Mysql database on swipe

I have an app with three fragments which I need to Asynctask every swipe. But it seems that the Asynctask runs only on the opening of the app. But when it's already created, only the first and third fragment functions well when it comes to AsyncTask the second doesn't change when I update the database.
This is my MainActivity.java

#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabAdapter = new TabPagerAdapter(getSupportFragmentManager());
Tab = (ViewPager)findViewById(R.id.viewPager);
Tab.setOnPageChangeListener(
new ViewPager.SimpleOnPageChangeListener() {
#Override

});
Tab.setAdapter(TabAdapter);

I had the same problem like u. I think that problem is because ViewPager saves states of last and next pager, and building them before they come. Try setting tab.setOffscreenPageLimit(0). By doing that u may encounter problem that when ever u swipe pages, pages will be rebuild.
