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.
