Question

I am working with 2 resolutions one touchScreen and other Non- touch

i have designed a Screen which has 10 custombuttons are added to a VerticalFieldManager
The CustomButtonField class extends Field class

i have used 2 methods fieldChange() and touchEvent() for touchScreens
the problem is whenever i do click on button it gets activated correctly for touchevent()
but then the fieldChange() method also gets called immediately afterwards

what should i do??
what’s the problem ??

Check the answers of the question BlackBerry touchEvent outside Field triggers fieldChanged provided by Paul Sylliboy and Arhimed.

In those answers, there was a method which only updates a boolean variable to identify that a touch event occured, and based on the value of that boolean an action is executed on the fieldChanged or navigationClick method.

BB UI Framework calls navigationClick(int status, int time)
automatically if there is any touch event after execution of
protected boolean touchEvent(TouchEvent message). And
navigationClick(int status, int time) calls the method
fieldChangeNotify(0) which causes fieldChange() (in the question)
or public void fieldChanged(Field field, int context) to be called.
