问题描述

安排活动的最佳方式是什么?

What is the best way to schedule an event?

我当时在考虑新的Calendar API，但至少要建立新的日历就需要互联网连接.

I was thinking about the new Calendar API, but it requires an internet connection at least to create a new calendar.

是否有用于创建不需要互联网连接的日程表的API?

Is there any API for creating a schedule which doesn't require internet connection?

AlarmManager 将使您做到这一点.

如果您想通过处理程序相对较早地安排活动， >是更好的选择.您可以使用它来发布可运行对象，如下所示:

If you want to schedule your event for relatively soon though Handler is a better choice. You can use it to post a runnable like this:

Runnable r = new Runnable() {
    public void run() {
        doSomething();
    }
}
Handler h = new Handler();
h.postDelayed(r, 1000); 

这将在一秒钟内执行您可运行对象的run方法.您可以更改postDelayed方法的第二个参数来更改经过的时间间隔.以毫秒为单位.

This will execute the run method of your runnable in one second. You can change the second parameter of the postDelayed method to change the interval of time that passes. It is in milliseconds.

编辑:还请注意，最佳"做某事的方法是主观的，并且通常取决于您要尝试做的事情.如果您可以更详细地了解您要安排的时间以及要安排的时间，则也许我们可以将其范围缩小到最佳".选择.但是如果没有更多信息，我们将无法告诉您哪个是最佳"

Also note that the "best" way to do something is subjective, and generally depends on exactly what you are trying to do. If you can be more specific about what you are trying to schedule and how far in advance you'd like to schedule it then perhaps we can help narrow it down to the "best" choice. But without more info there is no way that we can tell you which is "best"
