After the 'webView.loadUrl' doned in asynk I don't see immediately the webpage

how can I wait to show the webView until it loads all the web data? i have created this asynktask sketch:

@Override
protected Void doInBackground(String... params) {


    webView.setWebChromeClient(new WebChromeClient()); 
    webView.setWebViewClient(new WebViewClient()); 
    webView.getSettings().setJavaScriptEnabled(true);
    String url = params[0];
    webView.loadUrl(url);



    return null;
}

@Override
protected void onPreExecute() {
//progress = ProgressDialog.show(MainActivity.this,"wait","downloading URL");
    progressBar.setVisibility(View.VISIBLE);
}

@Override
protected void onPostExecute(Void result) {


            webView.setVisibility(View.VISIBLE);
            progressBar.setVisibility(View.GONE);



}

}

it works but a the end of this code, after onPostExecute i'm still seeing the blank page of webview loading

loadUrl is already doing everything asynchronously, so onPostExecute is called right away.

If you want to display a loading indicator, you need to use that : 

mWebView.setWebViewClient(new WebViewClient() {

    public void onPageStarted (WebView view, String url, Bitmap favicon) {
        view.setVisibility(View.GONE);
        progressBar.setVisibility(View.VISIBLE);
    }

    public void onPageFinished(WebView view, String url) {
        view.setVisibility(View.VISIBLE);
        progressBar.setVisibility(View.GONE);
    }
});
webView.loadUrl(url);

and of course remove you AsyncTask.
