Kotlin WebView refresh button - kotlin

Question

i googled a bit how to make a refresh button but i didn't really figured out how to make it. I already have the button in my activity_main but nothing in my MainActivity.kt yet. So my problem is now the function of the button to refresh the page again.
This is my Activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:ignore="MissingConstraints"
tools:layout_editor_absoluteX="8dp"
tools:layout_editor_absoluteY="8dp" />
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentStart="true"
android:text="REFRESH"
android:id="#+id/button"
tools:ignore="MissingConstraints" />
</androidx.constraintlayout.widget.ConstraintLayout>
And this is my MainActivity.kt
package com.example.myapplication
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import android.webkit.WebView
import android.webkit.WebViewClient
import android.widget.Button
class MainActivity : AppCompatActivity() {
private lateinit var webView: WebView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
webView = findViewById(R.id.webview)
webView.settings.setJavaScriptEnabled(true)
webView.setInitialScale(1);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setSupportZoom(true);
webView.webViewClient = object : WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView?, url: String?): Boolean {
if (url != null) {
view?.loadUrl(url)
}
return true
}
}
webView.loadUrl("example.com")
}
}

You can try adding this:
findViewById<Button>(R.id.button).setOnClickListener {
webView.reload()
}
