View Binding

View binding is a feature that makes it easier to write code and helps to find the id of the element of an XML file

Setup

goto the gradle (app) file and enable viewBinding

buildFeatures {
        viewBinding true
    }

use view Binding in activities

To set up an instance of the binding class for use with an activity perform the following steps in the activity's "onCreate()" method.
call the static "inflate()" method in the generated binding class. This creates an instance of the binding class for the activity to use
pass the root view to setOnClickListener() to make it the active view on the screen

 private lateinit var binding: ResultProfileBinding

 override fun onCreate(savedInstanceState: Bundle?) {
     super.onCreate(savedInstanceState)
     binding = ResultProfileBinding.inflate(layoutInflater)
     val view = binding.root
     setContentView(view)
 }

Project implementation

create XML file

```xml <?xml version="1.0" encoding="utf-8"?>


2. create kotlin file

    ```kotlin
    package com.example.learncode


    import android.content.Intent
    import androidx.appcompat.app.AppCompatActivity
    import android.os.Bundle

    import android.widget.Toast
    import com.example.learncode.databinding.ActivitySignupBinding
    import com.google.firebase.auth.FirebaseAuth


    lateinit var firebaseAuth: FirebaseAuth
    private lateinit var binding: ActivitySignupBinding

    class SignupActivity : AppCompatActivity() {
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            binding= ActivitySignupBinding.inflate(layoutInflater)
            setContentView(binding.root)


            firebaseAuth= FirebaseAuth.getInstance()

            binding.signupbtn.setOnClickListener {
                signupUser()
            }

            binding.acsigntxt.setOnClickListener{
                val intent = Intent(this,LoginActivity::class.java)
                startActivity(intent)
                finish()
            }

        }

        private fun signupUser(){

            val email = binding.signupemail.text.toString()
            val password = binding.tvpassword1.text.toString()
            val cpassword = binding.cpasswrd.text.toString()
            //validation
            if (email.isBlank()||password.isBlank()||cpassword.isBlank()){
                return
            }
            if (password!=cpassword){
                //Toast.makeText(this,"Password not mached",Toast.LENGTH_SHORT).show()
                return
            }
            firebaseAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this){
                if(it.isSuccessful){
                    val i = Intent(this,MainActivity::class.java)
                    startActivity(i)
                    finish()
                }else{
                    Toast.makeText(this,"Sign Up failed",Toast.LENGTH_SHORT).show()
                }
            }

        }
    }
