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

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

You just have use the method setCustomTitle, when create os start to load the webview.

Then, when onLoadCompleted, you can setCustomTitle again to the second one.

Here is the reference

I think before you call alert.show(), you should call alert.create(). This should solve your problem.

See this Example: THIS LINK

After implementing that you have to set the different value for the alert title based on the execution. So It shows the different Dialog based on the Webview is loading.

See this example for how it works and how to implement it.
