User registration and password validation confirmation in android

Problem Description:

I have this activity in which I want to authorize the confirm password field.This is my code-:

package com.example.loginregisterfirebase;

import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

import com.google.firebase.FirebaseApp;
import com.google.firebase.database.DataSnapshot;
import com.google.firebase.database.DatabaseError;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;
import com.google.firebase.database.ValueEventListener;

import java.lang.ref.Reference;

public class Register extends AppCompatActivity {
    //create object of DatabaseReference class to access firebase's Realtime Database
    DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReferenceFromUrl("https://loginregisterfirebase-9fe2f-default-rtdb.firebaseio.com/");
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register);

        final EditText fullname = findViewById(R.id.fullname);
        final EditText email = findViewById(R.id.email);
        final EditText phone = findViewById(R.id.phone);
        final EditText password = findViewById(R.id.password);
        final EditText conPassword = findViewById(R.id.conPassword);

        final Button registerBtn = findViewById(R.id.registrationBtn);
        final TextView loginNowBtn = findViewById(R.id.loginNowBtn);

        registerBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                //get data from EditTexts into String variables
                final String fullnameTxt = fullname.getText().toString();
                final String emailTxt = email.getText().toString();
                final String phoneTxt = phone.getText().toString();
                final String passwordTxt = password.getText().toString();
                final String conPasswordTxt = conPassword.toString().toString();

                // check if user fill all the fields before sending data
                if (fullnameTxt.isEmpty()||emailTxt.isEmpty()||phoneTxt.isEmpty()||passwordTxt.isEmpty()||conPasswordTxt.isEmpty()){
                    Toast.makeText(Register.this, "please fill the all the fields", Toast.LENGTH_SHORT).show();
                }
                //check if passwords are matching with each other
                //if not matching with each other then show a toast message
                else if (passwordTxt.equals(conPasswordTxt)){
                    Toast.makeText(Register.this, "Passwords do NOT match", Toast.LENGTH_SHORT).show();
                }
                else{
                    databaseReference.child("users").addListenerForSingleValueEvent(new ValueEventListener() {
                        @Override
                        public void onDataChange(@NonNull DataSnapshot snapshot) {
                            
                            //check if phone number is registered before
                            if (snapshot.hasChild(phoneTxt)){
                                Toast.makeText(Register.this, "Phone number is already registered", Toast.LENGTH_SHORT).show();
                            }
                            else {
                                // storing or sending data to firebase Realtime Database.
                                //we are using phone number as unique identity of every user
                                //so all the other details of user comes under phone number
                                databaseReference.child("users").child(phoneTxt).child("fullname").setValue(fullnameTxt);
                                databaseReference.child("users").child(phoneTxt).child("email").setValue(emailTxt);
                                databaseReference.child("users").child(phoneTxt).child("password").setValue(passwordTxt);

                                //show success message than finish activity
                                Toast.makeText(Register.this, "User registered successfully", Toast.LENGTH_SHORT).show();
                                finish();
                            }
                        }

                        @Override
                        public void onCancelled(@NonNull DatabaseError error) {

                        }
                    });

                }

            }

        });
        loginNowBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                finish();
            }
        });
    }

}

if I eleminate this section the application is working properly.:-

else if (passwordTxt.equals(conPasswordTxt)){
Toast.makeText(Register.this, "Passwords do NOT match", Toast.LENGTH_SHORT).show();
}

but I need this section anyhow…
Now even after I have both of the EditText fields to be same it is still showing me the Toast that passwords do not match. Please help me out here. Thanks in advance.

Solution – 1

final String conPasswordTxt = conPassword.toString().toString();

This should be final String conPasswordTxt = conPassword.getText().toString();
