How to listen for a WebView finishing loading a URL?

Question

I have a WebView that is loading a page from the Internet. I want to show a ProgressBar until the loading is complete.

How do I listen for

I am pretty partial to @NeTeInStEiN (and @polen) solution but would have implemented it with a counter instead of multiple booleans or state watchers (just another flavor but I thought might share). It does have a JS nuance about it but I feel the logic is a little easier to understand.

private void setupWebViewClient() {
    webView.setWebViewClient(new WebViewClient() {
        private int running = 0; // Could be public if you want a timer to check.

        @Override
        public boolean shouldOverrideUrlLoading(WebView webView, String urlNewString) {
            running++;
            webView.loadUrl(urlNewString);
            return true;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            running = Math.max(running, 1); // First request move it to 1.
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            if(--running == 0) { // just "running--;" if you add a timer.
                // TODO: finished... if you want to fire a method.
            }
        }
    });
}
