how to set different title for alert dialog when WebView page is loaded?

I want to set different title for alert dialog when WebView page is loaded but its not working.

here is the code snippet:

final AlertDialog.Builder alert = new AlertDialog.Builder(
        mContext);
// alert.setTitle("Loading...");
final WebView wv = new WebView(mContext);

wv.loadUrl("http://10.0.51.133/androidview/");
wv.getSettings().setJavaScriptEnabled(true);
wv.setVerticalScrollBarEnabled(false);

WebViewClientLoader loader= new WebViewClientLoader(alert);
wv.setWebViewClient(loader);
wv.setWebViewClient(new WebViewClient() {

    @Override
    public void onPageFinished(WebView view, String url) {
        // TODO Auto-generated method stub
        alert.setTitle("Loading...");
        super.onPageFinished(view, url);
    }

    @Override
    public void onPageStarted(WebView view, String url,
            Bitmap favicon) {
        // TODO Auto-generated method stub
        alert.setTitle("Finished");
        super.onPageStarted(view, url, favicon);
    }
});

private class webviewclient extends WebViewClient{

}

wv.loadUrl("file:///android_asset/Like.html");
alert.setView(wv);

alert.show();

        @Override
        public void onLoadResource(WebView view, String url) {
