Well why are you calling setContentView again and passing in your webview? — tyczj, Jul 12 '18 at 19:27
i want to open the web page in my owen activity not in chrome or firefox — Aniskonig, Jul 12 '18 at 19:35
So just remove the second setContentView in you onClickListener `loadUrl` will show the webpage — tyczj, Jul 12 '18 at 19:37
yes that true but it will open the webpage in chrome or firefox or t*other browsers not in my webview — Aniskonig, Jul 12 '18 at 19:43

wvbtn.setOnClickListener{
    setContentView(webv)
    webv.loadUrl("https://www.sona3elghad.ml")
}

setContentView(webv) this line is causing the error. If you want to load an url into your WebView, change your code to the following:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_license)

    webv = findViewById<WebView>(R.id.webv)
    webv.loadUrl("https://www.sona3elghad.ml")
}

i want to open the web page after a click in a button this is why i use that wvbtn — Aniskonig, Jul 12 '18 at 19:34
