ButtonField click event

i am not implementing touch event. i am usi开发者_Go百科ng FieldChangeListener the problem which i am facing is , if i am clicking outside the CustomButtonField then also the click event is generated how should i restrict only to the CustomButtonField.

Thanks alot

The listener will be invoked on all change events but you also get the field that changed (in the fieldChanged function), so why not use that to make sure it is your field that was "changed"?
