I have a class A which extends TabActivity and creates Activities B, C
and D as tabs in its onCreate() function. Also, class A initializes
another service handler class S which is responsible for establishing
a connection to a service and implementing callback handlers for the
service. Any of the Activities B, C and D should be able to receive
events from the service and update accordingly. If I receive any event
in class S from the the service then I want to call a function in
Activity B which would be responsible to update the UI elements in
Activity B based on the event received. You can assume that the user
is in Activity B when the event arrives.
Can I call an activity function like the following in the stub handler
for the callback in my class S -
private Callback mEventListener = new OperationCallback.Stub()
{
@Override
public void handleOperationEvent(Payload payload)
{
B objB = new B(); // Is this valid? Since B is an activity.
B.postEventToHandler(payload); // postEventToHandler() is a
method inside B
}
};
Let me know I am doing the right thing to achieve what I want. Also,
let me know if you need more clarification.
