Schedule TextView update

In my application in every activity at the top I have a fragment with TextView showing the current event that is taking place. It looks something like this:

--------------------
|    Event name    |
|------------------|
|                  |
|                  |
|                  |
|     Activity     |
|     content      |
|                  |
|                  |
|                  |
|                  |
|                  |
--------------------

I want to update the event name when the next event starts. I'm using singleton pattern and in my Application I have the currentEvent string that I show at every activity start. I keep the events in database and every event has start time. What is the best way to update the event name. How can I schedule event that will update the text view based on the start time for the next event?

Solution

  • I did it something like @Jeffrey said but with some changes:

    • In the Application class, in onCreate() I get the current and the next event and create the handler just like @Jeffrey said, but in the run() of the handler's Runnable I send a broadcast.

    • I register a BroadcastReceiver with the same IntentFilter in each CurrentEvent fragment. And in the onReceive() method of the receiver I update the TextView.
