Android Webview wait until it loads fully

I´ve searched in all topics but i've not found anything that works for me.
I have an android application with a webview. I set up the page with a small javascript code in OnPageFinished and i see how it hides and shows elements, but i don´t want to see that. I would want that webview shows the current page while it is loading and when it's loaded fully, webview shows the new page.
Is there any way to get it?? Sorry for my english. Thanks.

Show progress bar or progress dialog ,initialize a progress bar on your xml page and use it to load untill the your webpage has fullyloaded
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient());
webView.getSettings().setDomStorageEnabled(true);
webView.post(new Runnable() {
#Override
public void run() {
webView.loadUrl("file:///android_asset/Guage.html");
}
});
webView.setWebViewClient(new myWebClient());
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
progressBar.setVisibility(View.VISIBLE);
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
}

Not able to open url in webview

When I load url it shows a window to select browser. For ex. - If I want to open "http://www.facebook.com/" then it show me window to choose chrome or default browser. I am not able to understand why this is happening.
Actually in below code if i successfully got url from server then I hide a sorry image and show webview. Otherwise I show webview and hide sorry image.
webView = (WebView) findViewById(R.id.webView);
webView.setVisibility(View.VISIBLE);
ImageView img = (ImageView) findViewById(R.id.image);
img.setVisibility(View.GONE);
webView.setInitialScale(1);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setScrollbarFadingEnabled(false);
webView.loadUrl("http://www.facebook.com/");

Try to add this line
webView.setWebViewClient(new WebViewClient());

Add a WebViewClient like this
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
You should override your shouldOverrideUrlLoading() method.
In your UI activity add this line
web.setWebViewClient(new myWebClient());
It will solve your problem. Hope it helps!

Firstly, replace http with https and then in a order to do this, you need to first create a new java class that extends the WebViewClient class and overrides the onPageFinished method like this:
public class CustomWebViewClient extends WebViewClient
{
#Override
public void onPageFinished(WebView view, String url) {
//https://www.facebook.com/dialog/permissions.request
//actually works for me, but I put the URL you say is coming up
//blank in there instead, whatever works for you:
if(url.startsWith("https://www.facebook.com/dialog/oauth")){
String redirectUrl = "http://www.yourdomain.com/MyApp/";
view.loadUrl(redirectUrl);
return;
}
super.onPageFinished(view, url);
}
}
Second, just add it to your WebView:
webview.setWebViewClient(new CustomWebViewClient());

How To Display Custom "Web Page Not Available" Error Page in WebView

pls help me to display custom Web Page Not Available error page...in webview..i tried many code and when i run the app it shows app has been stopped

You can override onReceivedError callback of WebViewClient to achieve the desired functionality.
Either you can display some dialog to denot your custom message or load the webview with any custom html available locally in your app.

USE this it working fine on my side. May be it will help you
private WebView webviewSites;
String URL="http://www.google.com";
webviewSites = (WebView) findViewById(R.id.webview_sites);
WebSettings webSettings = webviewSites.getSettings();
webSettings.setSupportMultipleWindows(true);
webSettings.setJavaScriptEnabled(true);
webviewSites.setWebViewClient(new myWebClient());
webviewSites.loadUrl(URL);
public class myWebClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(final WebView view, final String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
// mProgressBar.setVisibility(View.GONE);
Log.i("LOAD_URL", "" + url);
}

You need to enable javascript in your WebView like this:-
web.getSettings().setJavaScriptEnabled(true);
