Here is a step by step answer:
<ul>
<li>From right side of the Android studio click on <code>Gradle</code></li>
<li>Right click on the app and click <code>Open Gradle Config</code></li>
<li>New source opening in <code>plugins</code> part and then add this:</li>

Result: now you can import <code>kotlinx.android.synthetic.main.activity_main.*</code>

Kotlin:

<li>open gradle app.module and add this line inside
android{
<pre><code> android{viewBinding.enabled = true
 ...

 }
</code></pre>
</li>
</ol>
(then sync)
<ol start="2">
<li>go to MainActivity.kt and do this:</li>
</ol>
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val binding = ActivityMainBinding.inflate(layoutInflater) // 2.1
setContentView(binding.root) // 2.2 instead of (R.layout.activity_main)
now views are called this way
<pre><code>binding.btn1.setOnClickListener{...}
</code></pre>
or
<pre><code>binding.txtviewTitle.text = &quot;Welcome to the jungle&quot; // or any R.string
</code></pre>
note: after you sync the gradle module.app with the line you will find any activity with the same name+Binding
Look 2.1 reference
