To implement a custom progress bar, you'll need a Runnable thread and a message handler which will keep updating your progress bar.

Check the snippet below:-

Get your progress bar and then start the new Thread

myProgressBar=(ProgressBar)findViewById(R.id.progressbar);
new Thread(myThread).start();

New Thread:-

private Runnable myThread = new Runnable(){

@Override
public void run() {
while (myProgress<100){
try{
myHandle.sendMessage(myHandle.obtainMessage());
Thread.sleep(1000);
}
catch(Throwable t){
}
}
}
}

The message sent from the try block above, will be handled in the handleMessage method of your Handler below:-

Handler myHandle = new Handler(){

@Override
public void handleMessage(Message msg) {
myProgress++;
myProgressBar.setProgress(myProgress);
}
}

Hope this helps!

That was for custom progress bar. If you need to play around with the Webview then I think this should help you out.

A WebView has several customization points where you can add your own behavior. They are:

Creating and setting a WebChromeClient subclass. This class is called when something that might impact a browser UI happens, for instance, progress updates and JavaScript alerts are sent here.

Creating and setting a WebViewClient subclass. It will be called when things happen that impact the rendering of the content, eg, errors or form submissions. You can also intercept URL loading here(via shouldOverrideUrlLoading()).

// To display the progress in the activity title bar, like the
// browser app does.
getWindow().requestFeature(Window.FEATURE_PROGRESS);

webview.getSettings().setJavaScriptEnabled(true); // javascript if needed.

final Activity activity = this;
webview.setWebChromeClient(new WebChromeClient() {
   public void onProgressChanged(WebView view, int progress) {
     // The progress meter will automatically disappear when we reach 100%
     activity.setProgress(progress * 1000);
   }
 });

 webview.setWebViewClient(new WebViewClient() {
   public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Toast.makeText(activity, "Page Load Error! " + description, Toast.LENGTH_SHORT).show();
   }
 });

 webview.loadUrl("http://www.stackoverflow.com");

Please refer this and this too for more clarity.
