Passing a Int value to another class

I have four groups in a listview each with four url's I want to load in a webView. When the user select a url to goto I set a value like so;

 if (position == 0) webb = webb +2;
 {
       Intent intent = new Intent(this, official.class);
       startActivity(intent);
 }

I then carryout the intent to move to the webView class where I have given each url a value like so;

if (webb == 2) mWebView.loadUrl("http://yahoo.com");
if (webb == 3) mWebView.loadUrl("http://www.bbc.co.uk");

But the screen stays blank, if I state the value inside the official.class it works.

How can I get this value to pass to another class based on the selection the user makes from the listview. Sorry if this is hard to understand.

If your question is how to share data between activities (such as your webb value), then you might want to look at the Intent.putExtra(...) methods. More info:

Hope this helps

As far as I understand your question... Try using extras to pass info along with the intent. More info can be found here
