Answer 1

pass your url in this method

private void startWebView(String url) {

        WebSettings settings = webView.getSettings();

        settings.setJavaScriptEnabled(true);
        webView.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);

        webView.getSettings().setBuiltInZoomControls(true);
        webView.getSettings().setUseWideViewPort(true);
        webView.getSettings().setLoadWithOverviewMode(true);

        progressDialog = new ProgressDialog(ContestActivity.this);
        progressDialog.setMessage("Loading...");
        progressDialog.show();

        webView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                if (progressDialog.isShowing()) {
                    progressDialog.dismiss();
                }
            }

            @Override
            public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
                Toast.makeText(ContestActivity.this, "Error:" + description, Toast.LENGTH_SHORT).show();

            }
        });
        webView.loadUrl(url);
    }

Put a progress bar and the webview inside a relativelayout and set the properties for the progress bar as follows,

1. Make its visibility as GONE.
2. CENTRE it in the Relativelayout.

and then in onPageStarted() of the webclient make the progress bar visible so that it shows the progressbar when you have clicked on a link. In onPageFinished() make the progress bar visiblility as GONE so that it disappears when the page has finished loading... This will work fine for your scenario. Hope this helps...
