When i press Edit, i want the javascript to do what it has to?. When i press edit, the JS function has to show checkbox. I am not being able to pass the value to the html page. Any help will be appreciated.

your question is not clear. You want to check a checkbox in an HTML-page after you press the edit button in an android menu? use addJavascriptInterface to pass values from javascript to java: http://developer.android.com/guide/webapps/webview.html

or just use webview.loadUrl("Javascript:...") to let javascript do something.
