我正在 Android 2.1 上开发任务管理器。我想为日期选择器中的日期和时间选择器中的时间设置的任务设置警报帮助我使用代码..

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    final EditText next = (EditText) findViewById(R.id.editText1);
    final Button sub = (Button) findViewById(R.id.button1);
    final Button res = (Button) findViewById(R.id.button2);
    final DatePicker dp = (DatePicker) findViewById(R.id.datePicker1);
    final TimePicker tp = (TimePicker) findViewById(R.id.timePicker1);

    sub.setOnClickListener(new View.OnClickListener() {
        public void onClick(final View view) {

             int y=dp.getYear();
             int mo=dp.getMonth();
             int day=dp.getDayOfMonth();

            Time t = new Time();
                                    int h=t.getCurrentHour();
                                    int m=t.getCurrentMinutes();

    }

 private AlarmManager getSystemService(String alarmService) {

            // TODO Auto-generated method stub
            return null;
        }

    });

嘿，这是如何将 android AlarmManager 上的警报设置为特定日期（android alarmmanager 设置警报日期）我一直在寻找这个。注意月值！！

Calendar cal = Calendar.getInstance(TimeZone.getDefault(), Locale.getDefault());
//cal.add(Calendar.SECOND, 10);

cal.set(Calendar.DATE,19);  //1-31
cal.set(Calendar.MONTH,Calendar.DECEMBER);  //first month is 0!!! January is zero!!!
cal.set(Calendar.YEAR,2012);//year...

cal.set(Calendar.HOUR_OF_DAY, 16);  //HOUR
cal.set(Calendar.MINUTE, 39);       //MIN
cal.set(Calendar.SECOND, 10);       //SEC


// Create a new PendingIntent and add it to the AlarmManager
Intent intent = new Intent(MainActivity.this, alarmAct.class);
PendingIntent pendingIntent = PendingIntent.getService(MainActivity.this, 0,intent, 0);

//or if you start an Activity
//PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0,intent, 0);

AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

这是设置闹钟的方法。

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());

//when does this go off?
Long mHowLongFromNowInMilliseconds = 10000 //(10 seconds from now)
calendar.add(Calendar.MILLISECOND, mHowLongFromNowInMilliseconds);

alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

不需要日历......但它可能会有所帮助;）

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, 10000, pendingIntent);

！！！请记住：当设备完全断电时，警报会被取消。

Android 不会为您播放警报，Alarm Manager 允许您安排您的应用程序在未来某个时间点运行。因此，只需在 AlarmManager 中添加时间和挂起的意图，当调用此意图时，播放音乐。

        }
    };
}
