Data doesn't show in recyclerView, need to go back to show it

I want to create an activity to search for users by full name. I created everything I needed and it worked properly, except for one thing. When I press search button the result are not show in recyclerview. I need to go back and the the results are shown. I need to do these 2 steps to see the results.
Yes the search bar and view holder are overlap, I will try to fixed later. Do you know how to make it so that once searched the results are displayed immediately without having to go back
This is my layout for view holder

I think it's the RecyclerView in your XML that needs to be adjusted at android:layout_height = "0dp"
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="#+id/linearlayout"/>

What is alternative for "android:usesCleartextTraffic" in android API LEVEL 29?

I'm developing wordpress android app which loads Wordpress post data in android webview. I'm using retrofit & JSON API to fetch data from my Wordpress site. My app worked fine in android API LEVEL 26 but the problem is I need API 28+ to upload to google play store. I migrated to androidx API LEVEL 29. post were not getting loaded showing ERR_CLEARTEXT_NOT_PERMITTED so I used "android:usesCleartextTraffic=true" post was loading but the problem is HTML entities like &#8211,&#8220,&#8217 etc failed to decode and decoded as & and remaining lines of the post are not loaded after this. I dint use "android:usesCleartextTraffic=true" in API LEVEL 26 but it works fine without any error. I'm searching a solution for my problem I didn't find satisfying answers anywhere. I'm stuck at this point. So I'm trying alternative method for "android:usesCleartextTraffic=true". I have "text to speech" function in my app its working absolutely fine I mean its reading entire post which is not visible in android webview. Kindly suggest. Please find the code for your reference.

Recycler View shows data in portraint but not in landscape even i set it again after orientation changes

> I have used MVVM to backup my data when screen orientation changes,
> the data loads perfectly but when i set the data to the adapter class
> recylerview goes empty even when onbind and getItem count gets called.
first i thought my data not getting loaded but then i tracked the data loads and everything goes fine but recycler view shows no view inside it.

This is the row_assignment.xml which i am inflating in the oncreateViewholder
inside the adapter class this is the layout which wasn't working to load on landscape mode. But i have now created a new resource with landscape and copied the same code from the row_assignment.xml and it worked. I am not sure why it wasn't working because by default android would have picked up the simple row_assignment.xml even if the row_assignment.xml (landscape) wasn't present.

I think my syntax is incorrect for writing/reading from Firebase, but I'm unsure where to start

I am attempting to make a simple app for personal and maybe a few coworkers to use. I am having trouble successfully reading and writing into a Firebase Database.
Some of this code is ripped so there may be mistakes I am looking over without realizing.
I am fairly positive this is something silly and stupid easy to fix, but I just can't see it and have had no success with searching.
The way I am thinking of putting the information into the database is in this fashion.
possible layout?
If there is a better way to lay this out, I'm all ears lol. Hope someone can point me in the right direction. All the files have the proper top lines or 2, and sometimes missing the bottom brace. My computer is being super derpy and deleting some lines for some reason when I am trying to copy/paste.
Rundown of what I am trying to accomplish.
App that will show/store NSNs, name, and description of items
User can enter all of this information themselves to be entered into the database or can search a database for the information. Search part is coming next after I get the easier part down.
information is presented in a CardView form, eventually to be made clickable for more information. information on card will be NSN, name, description, and eventually a picture.
All information is either from user input or directly into the database.

First, in your POJO make sure the name of the constants are equal to the ones in your firebase database, first in your firebase database you have item Name and in your pojo itemName , you should put in your firebase either item_Name or itemName , if you put item_Name refactor the name in your pojo but keep the same names in the pojo and the firebase
Second, your reference must be like this .child("items").child("item_NSN").... , or .child("items/item_NSN")..... but please do not use blank spaces in names inside firebase
Last, please update your firebase rules if they are not able to write and read for everyone without sign in first
go to your realtime database and find rules, inside you should have this
// These rules require authentication
{
"rules": {
".read": "auth != null",
".write": "auth != null"
}
}
if you want to each one read and write data without authentication just change that rules to this
// These rules do not require authentication
// These rules give anyone, even people who are not users of your app,
// read and write access to your database
{
"rules": {
".read": true,
".write": true
}
}

So my brain is no longer fried. So when trying to enter information via the submit button, I "think" I fixed my reference but I'm not 100%. Still a little confused from it.
btnSubmit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String itemNSN;
ItemInfo itemInfo = new ItemInfo();
GetDataFromEditText();
// Adding item name into class function object.
itemInfo.setItemName(nameHolder);
// Adding item NSN into class function object.
itemInfo.setItemNSN(nsnHolder);
itemNSN = nsnHolder;
//Adding item desc into class function object
itemInfo.setItemDesc(descHolder);
// Getting the ID from firebase database.
String ItemIDFromServer = databaseReference.push().getKey();
// Adding the both name and number values using student details
class object using ID.
databaseReference.child("items").setValue(itemNSN);
databaseReference.child("items/itemNSN").setValue(itemInfo);
// Showing Toast message after successfully data submit.
Toast.makeText(MainActivity.this,"Successfully Added",
Toast.LENGTH_LONG).show();
}
});
Then to pull all the information via the return button, I am unsure of what is supposed to be but I haven't changed it at all. I have the cardview layout I would like for it. but this is my btnReturn clickListener.
btnReturn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MainActivity.this,
ShowItemInfo.class);
startActivity(intent);
}
});
