Despite this

Answer 1

In XML File :-

In MainActivity :-

        webView.setWebChromeClient(new WebChromeClient(){
        @Override
        public void onProgressChanged(WebView view, int newProgress) {
            super.onProgressChanged(view, newProgress);
            mProgressBar.setProgress(newProgress);
        }

        webView.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String request)
        {
            webView.loadUrl(request);
            return true;
        }
        public void onPageFinished(WebView view, String url) {
            mProgressBar.setVisibility(View.GONE);
            super.onPageFinished(view, url);
        }
