Answer 1

I try dismis progress on method onPageFinished(), but not good too much, it has time delay to render webview.

try with onPageCommitVisible() better:

val progressBar = ProgressDialog(context)
    progressBar.setCancelable(false)
    progressBar.show()
    val url = "your url here"
    web_container.settings.javaScriptEnabled = true
    web_container.loadUrl(url)

    web_container.webViewClient = object : WebViewClient() {
        override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
            view.loadUrl(url)
            progressBar.show()
            return true
        }

        override fun onPageFinished(view: WebView?, url: String?) {
            super.onPageFinished(view, url)
        }
        override fun onPageCommitVisible(view: WebView?, url: String?) {
            super.onPageCommitVisible(view, url)
            progressBar.dismiss()
        }
    }
    web_container.setOnKeyListener(View.OnKeyListener { _, keyCode, event ->
        if (keyCode == KEYCODE_BACK && event.action == MotionEvent.ACTION_UP
                && web_container.canGoBack()) {
            web_container.goBack()
            return@OnKeyListener true
        }
        return@OnKeyListener false
    })
