Question

I want to execute some function at specific hour picked by TimePicker.

I can use Handler like this:

Handler myHandler = new DoSomething();
Message m = new Message();
myHandler.sendMessageDelayed(m, delay);

class DoSomething extends Handler {
    @Override
    public void handleMessage(Message msg) {
      MyObject o = (MyObject) msg.obj;
      //do something here
    }
}

And load the “delay” param with: picked_wanted_hour – current_hour
OR check for the current time at some interval and invoke the function when the time comes.

But, is there any handler-like object that can take a specific time and invoke the operation at that time?

Thanks in advance.

Answer 1

Why don’t you use handler itself? Just pass timePickerTime - currentTime as a delay.
There’s also Timer with method schedule(TimerTask task, Date when).
