在特定时间执行函数

发布于 2024-11-08 21:05:10 字数 499 浏览 0 评论 0原文

我想在 TimePicker 选择的特定时间执行某些功能。

我可以像这样使用处理程序：

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
    }
}

并加载“延迟”参数：picked_wanted_hour - current_hour 或者以一定的时间间隔检查当前时间，并在时间到来时调用该函数。

但是，是否有任何类似处理程序的对象可以花费特定时间并在那时调用操作？

提前致谢。

原文

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.

您可以使用 AlarmManager 服务：

http://developer.android.com/reference/android /app/AlarmManager.html

简要示例：

Intent intent = new Intent(this,<Activity.class/ or type of broadcast receiver>);
PendingIntent pi = PendingIntent.get(...)
AlarmManager am = getSystemService(Context.ALARM_SERVICE);
int delay = 1000; // 1 second
am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + delay, pi);

A bref sample:

PendingIntent pi = PendingIntent.get(...)
AlarmManager am = getSystemService(Context.ALARM_SERVICE);
int delay = 1000; // 1 second
am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + delay, pi);
