Item List Layout showing up in Android Studio, but not in Emulator

I am working on an Android App with a Recyclerview that contains a Listview. The problem is, that the Listview items are showing up in Android Studio, that there are no errors in the XML but still, the Listview items are not showing up on the Emulator or on a Real device. I checked the Layout for all kinds of problems - Size, Width, Layout Constraints -, but I couldn´t find any. As I am stuck here, I would kindly appreciate any help or hints from the community, thanks in advance.

When you are setting the Adapter, stockBookingList is empty.
This means that when RecyclerView decides to render items on the list, it finds the itemCount to be 0.
This instructs the RecylcerView to not render anything on the list, since it won't call onCreateViewHolder or onBindViewHolder – two methods responsible for inflating your list item and setting necessary data.
If you have a static list of items, you need to provide them to the adapter.
If the list is coming from your RestClient, you need update the adapter as and when you receive data from your API.

Android Initial Login Screen then use fragments to swipe between screens once login is successful

I am trying to create an Android app, then has an initial login screen that detects if a user is Admin or User. Once logged in, the user (depending on their role) will see different tabs to swipe between. I have a basic app that starts with a login activity and the login to decipher the users roles (using static values for now). First part is ok. Now when I try to use Fragments after the login screen, I'm getting stuck.
I have a LoginActivity that has an onClikcListener on a button after user enters credentials. Depending on whether the user is Amin or General Users, it will just to a new activity either activity_vote_admin or activity_vote_user. At this point I am stuck. Any ideas if what I am trying to do is valid. Or is there a better way to do this. At the moment I am getting this error.

...

There are two reason for this issue :
You didn't declare any button on "activity_vote_main_admin.xml", thats why your view not binding with activity and giving null pointer exception.
May be you declare the button on fragment xml and trying to bind it with activity.

I'm having trouble with phone number authentication. Verify_otp generates a unique code for any verified number

I'm having trouble with phone number authentication. Verify_otp generates a unique code for any verified number. But the biggest problem is that it only generates the code if the numbers start with 6599 ..... a number 6598 .... it no longer generates the code.
I can not find an outlet for him to accept any phone number.
this is a part of the RegistrationModel.java file
public static class OTP_Details{
/**
* status : 2
* message : Otp Sent to phone for Verification
* otp : 2017
* auto_otp : 1
*/
private int status;
private String message;
private String otp;
private int auto_otp;
public int getStatus() {
return status;
}
public void setStatus(int status) {
this.status = status;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getOtp() {
return otp;
}
public void setOtp(String otp) {
this.otp = otp;
}
public int getAuto_otp() {
return auto_otp;
}
public void setAuto_otp(int auto_otp) {
this.auto_otp = auto_otp;
}
}
}

Ready! I've submitted below the files I've listed. After typing the phone and clicking send otp, the code that comes back is always the code 2017, that is the first code I sent, but it only sends this code 2017 if the numbers start like this: 6599 .... if the number is so for example: 6598 .... it does not generate the code 2017 and can not continue the registration.

how to move main content and action bar to right in navigation drawer using fragments

i have a custom navigation drawer that opens from left to right using fragment. i want to move my content and action bar to right when navigation opens, i read some sources, they override onDrawerSlide method to do so, but since i using fragment to open and close navigation, i do not have such a method to override, I'll be grateful someone could help me (:
I tried this link to move the contents
and used this to create a custom navigation view
there is main activity :
<?xml version="1.0" encoding="utf-8"?>

}
}
as you can see, i am using loadFragment and hideFragment to open and close drawer, so how can i move main content (there is a simple textview but consider it whole lots of stuff)

Hey you can use this I guess you want the same output

Why pass textInput content to string into ArrayList

I want pass values from a form making with TextInputLayout but Android Studio detects my content as INT.
I put the complete class of my activity as well as the view in .xml to determine the problem
import android.content.Context;
import android.content.Intent;

public class AccionActivity extends AppCompatActivity {
ImageView imageView;
private Context activity;
private String[]header={"Campo","Respuesta"};
private String shortText="RSO PROSEGMA";
private String longText="Eliminamos Riesgos Sumamos Valor";
private AccionPdf accionPdf;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_accion);
Button btnCamera1 = (Button)findViewById(R.id.BtnCamera1);
imageView = (ImageView)findViewById(R.id.reporte1);
btnCamera1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent,0);
}
});
Date date = new Date();
String timeStamp = new SimpleDateFormat("dd/MM/yyyy").format(date);
accionPdf=new AccionPdf(getApplicationContext());
accionPdf.openDocument();
accionPdf.addMetaData("Reporte","Acción Insegura","www.prosegma.com");
accionPdf.addTitle("Reporte Acción Insegura","RSO Prosegma"," " +timeStamp);
accionPdf.addParagraph(shortText);
accionPdf.addParagraph(longText);
accionPdf.createTable(header,getClients());
accionPdf.closeDocument();
}
TextInputEditText Nreport = (TextInputEditText) findViewById(R.id.nReporta);

rows.add(new String[]{"Nombre de quien reporta", Nreport });
rows.add(new String[]{"Nombre del trabajador","No"});
rows.add(new String[]{"Empresa contratista","ju"});
rows.add(new String[]{"Medidas Necesarias","hu"});
return rows;
}
public void pdfAccion(View view)
{
accionPdf.verReporteAccion();
}
public void enviarA(View view) {
Intent email = new Intent(Intent.ACTION_SEND);
email.putExtra(Intent.EXTRA_EMAIL, "receiver_email_address");
email.putExtra(Intent.EXTRA_SUBJECT, "subject");
email.putExtra(Intent.EXTRA_TEXT, "email body");
Uri uri = Uri.fromFile(new File(android.os.Environment.getExternalStorageDirectory(), "pdfFileName"));
email.putExtra(Intent.EXTRA_STREAM, uri);
email.setType("application/pdf");
email.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getActivity().startActivity(email);
}
public Context getActivity() {
return activity;
}
}
I update the publication with the activity, I have tried to change the InputTextLayout by EditText but the situation is the same, it throws me an incompatibility error.

TextInputEditText Nreport = (TextInputEditText) findViewById(R.id.nReporta);
this line is outside OnCreate(Bundle savedInstanceState) method. Thats why it throws null. It should be like this
public class MainActivity extends AppCompatActivity {
TextInputEditText Nreport;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Button btnCamera1 = (Button)findViewById(R.id.BtnCamera1);
// imageView = (ImageView)findViewById(R.id.reporte1);
Date date = new Date();
String timeStamp = new SimpleDateFormat("dd/MM/yyyy").format(date);
Nreport = (TextInputEditText) findViewById(R.id.nReporta);
getClients();
}
private ArrayList<String[]> getClients(){
ArrayList<String[]>rows=new ArrayList<>();
rows.add(new String[]{"Nombre de quien reporta", Nreport.getText().toString() }); // get text like this
rows.add(new String[]{"Nombre del trabajador","No"});
rows.add(new String[]{"Empresa contratista","ju"});
rows.add(new String[]{"Medidas Necesarias","hu"});
return rows;
}
