My Webview show blank in kotlin fragment why?

Question

my webview show blank page

this is my Activity Class.

class AboutFragment : BaseGreenHCMFragment() { 
    override val layoutId = R.layout.fragment_about
    override fun setupData() {}
    override fun setupView() { 
        val mWebView: WebView? = view?.findViewById(R.id.webviewdaum) as WebView
        mWebView?.loadUrl("greenhcm.com/") 
        val webSettings = mWebView?.getSettings()
        webSettings?.setJavaScriptEnabled(true) 
        // Force links and redirects to open in the WebView instead of in a browser 
        //mWebView?.setWebViewClient(WebViewClient())
    }
}

this is my xml & fragment

class AboutFragment : BaseGreenHCMFragment() { override val layoutId = R.layout.fragment_about override fun setupData() {} override fun setupView() { val mWebView: WebView? = view?.findViewById(R.id.webviewdaum) as WebView mWebView?.loadUrl("https://www.greenhcm.com/") val webSettings = mWebView?.getSettings() webSettings?.setJavaScriptEnabled(true) // Force links and redirects to open in the WebView instead of in a browser //mWebView?.setWebViewClient(WebViewClient()) } } — Iqbal Alhadad, Oct 27 '20 at 02:48

anyway check this code.

class MainActivity : AppCompatActivity() {
   var mywebview: WebView? = null
   override fun onCreate(savedInstanceState: Bundle?) {
       super.onCreate(savedInstanceState)
       setContentView(R.layout.activity_main)
       mywebview = findViewById<WebView>(R.id.webview)
       mywebview!!.webViewClient = object : WebViewClient() {
           override fun shouldOverrideUrlLoading(view: WebView?, url: String?): Boolean {
               view?.loadUrl(url)
               return true
           }
       }
       mywebview!!.loadUrl("https://www.google.co.in/")
   }

}

you need WebViewClient in your code.
