android - 在选定的时间和日期设置闹钟

Question

我正在 Android 2.1 上开发任务管理器。我想为日期选择器的日期和时间选择器的时间设置的任务设置闹钟帮助我编写代码..

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，这是如何在 android AlarmManager 上将闹钟设置为特定日期 (android alarmmanager 在日期设置闹钟) 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);
