Hi All,
I realize that this question of mine has already been asked before (probably
not in the same context but similar). However, even after reading a number
of forum threads and looking at online examples, I am still not clear. I
hope one of you can guide me.
Here is the issue that I am facing. I have an activity which has a button.
This button needs to be enabled/disabled depending on an external condition.
We have a 3rd party library which has an observer class.
So basically in my android application, I have created a new class which
extends this 3rd party observer class. Code snippet as follow:
class myObserver extends third.party.observer
{
@Override
public void onConnect()
{
// when this function is called I wish to enable the button on my
UI.
}
@Override
public void onDisconnect()
{
// when this function is called I wish to disable the button on my
UI.
}
}
In my activity class, I create a new myObserver object and register it for
events from our third party library as follow:
public class myActivity extends Activity
{
private static myObserver tester = new myObserver()
@Override
public void onCreate(Bundle savedInstanceState)
{
....
....
third_party_registerObserverFunction(tester)
}
}
My question is how can use myObserver class to update the button in
'myActivity'.
The function 'onConnect' and 'onDisconnect' can be called at any time and I
don't wish to implement polling (or timer) to check for variable status.
Please advice.
Thanks
