Answer 1

You need do something like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_PROGRESS);
    this.setProgressBarVisibility(true);
}

And then

final Activity activity = this;
mWebView.setWebChromeClient(new WebChromeClient() {
    public void onProgressChanged(WebView view, int progress) {
        activity.setProgress(progress * 100);
    }
});

Answer 2

Try this:

getWindow().requestFeature(Window.FEATURE_PROGRESS);

WebView mWebView = (WebView) findViewById(R.id.mywebview);

mWebView.getSettings().setJavaScriptEnabled(true);

final Activity activity = this;

mWebView.setWebChromeClient(new WebChromeClient(){

         public void onProgressChanged(WebView view, int progress) {
                 activity.setTitle("Loading...");
                 activity.setProgress(progress * 100);
                    if(progress == 100)
                       activity.setTitle("My title");
                 }
});

mWebView.loadUrl(URL);
