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);
}
}

}
}
Where is the error here? please help me im also having problem with adview. here

You've created a custom WebViewClient class but you aren't using it.
Change web.setWebViewClient(new WebViewClient());
to web.setWebViewClient(new webclient());

Change these two methods.
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
progressBar.dismiss();
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
}
Change web.setWebViewClient(new WebViewClient());
to web.setWebViewClient(new webclient());

Show activity circle before loading webview - Android

I am using webview to show a webpage in my app. The webpage takes about 2-3 seconds to load.
Till the webpage loads, I want to show an activity circle progress bar like the one shown here. This is what an activity circle looks like :
How can I accomplish it?
I searched the web but couldn't find a satisfactory and proper explanation of how it is implemented. Thanks!
WebViewPage.java
public class Webpage extends Activity {
WebView web;
ProgressBar progressBar;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.web_page);
Intent startwebpage = getIntent();
web = (WebView) findViewById(R.id.webView);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://www.google.com");
}
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(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
}
}
}

Display progressBar in onPageStarted method and dismiss it in onPageFinished.
private ProgressDialog progressBar;
Show progressBar in onPageStarted:
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
// prepare for a progress bar dialog
progressBar = new ProgressDialog(v.getContext());
progressBar.setCancelable(true);
progress.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressBar.show();
}
2.Dismiss it in onPageFinished:
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
progressBar.dismiss();
}
EDIT : Use ProgressBar instead of ProgressDialog.
Use Following code in your layout.
Use drawable of your choice for "#drawable/progress"
<ProgressBar
android:id="#+id/progress_bar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:visibility="gone"
android:indeterminateDrawable="#drawable/progress" >
</ProgressBar>
Inflate it in your activity. Make it visible in onPageStarted and gone in onPageFinished.
private ProgressBar prgrsBar;
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
prgrsBar.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
prgrsBar.setVisibility(View.GONE);
}

This works for me:
ProgressDialog pb = null;
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
// prepare for a progress bar dialog
if (pb == null) {
pb = new ProgressDialog(Quiz.this);
pb.setCancelable(true);
pb.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pb.show();
}
}
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
pb.dismiss();
}

WebView not working

i want to disable phone browser and i want to use a webview .
but this code didn't work for me . please guide me :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Wop=(WebView)findViewById(R.id.webi);
String mturl="http://www.google.com";
Wop.getSettings().setJavaScriptEnabled(true);
Wop.loadUrl(mturl);
}

mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new HelloWebViewClient());
mWebView.loadUrl("http://www.stackoverflow.com");
To enable the previous web-page to be loaded,
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
} }
Definiton of the HelloWebViewClient class :
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
//what you want to do when the page finished loading, eg. give some message, show progress bar, etc
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
//what you want to do when the page starts loading, eg. give some message
}
}

WebView w = new WebView(this);
//add this to your code
w.setWebViewClient(new Callback());
w.loadUrl("http://www.facebook.com");
//and this class also
private class Callback extends WebViewClient{ //HERE IS THE MAIN CHANGE.
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return (false);
}
}
