Why couldn't a callback be used here?
in your myObserver class create an interface for your callback:
-----------------------------------------------------------
public OnConnectListener listener;
public void setOnConnectListener(OnConnectListener listener) {
this.listener = listener;
}
public interface OnConnectListener {
public abstract void onConnect();
}
-----------------------------------------------------------
Then when your myObserver class connects you can call
listener.onConnect(); to send a callback to your activity.
This interface will have to be implemented in your activity like so:
__________________________________
myObserver tester = new myObserver()
tester.setOnConnectListener(new OnConnectListener() {
@Override
public void onConnect() {
txtview.setEnabled(false);
}
});
Hope that works for you. I find it's a very sleek way of handling
updating the UI based on external events.
