AlarmClock 仅一次，每年特定日期特定时间

Question

我对 android 开发很感兴趣，我想知道是否可以在 android 每年的特定日期特定时间播放一些歌曲，以及如何播放。谢谢！

public class AlarmActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_alarm);

    Intent myIntent = new Intent(AlarmActivity.this , MyBroadcastReceiver.class);
    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
    PendingIntent pendingIntent = PendingIntent.getService(AlarmActivity.this, 0, myIntent, 0);
    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.HOUR_OF_DAY, 02);
    cal.set(Calendar.MINUTE, 18);
    cal.set(Calendar.SECOND, 55);
    alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 60000 , pendingIntent);  //set repeating every year


}

}

广播：

    public class MyBroadcastReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Broadcast Received.", Toast.LENGTH_LONG).show();
        // Vibrate the mobile phone
        Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(2000);
    }
}

Answer 1

查看official documentation了解如何设置闹钟。

至于你的具体目标，你可以在当前的闹钟响起时为下一年设置一个新的闹钟。

Answer 2

Intent myIntent = new Intent(MainActivity.this , NotifyService.class);     
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
pendingIntent = PendingIntent.getService(ThisApp.this, 0, myIntent, 0);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, YOUR_HOUR);
cal.set(Calendar.MINUTE, 00);
cal.set(Calendar.SECOND, 00);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 31556952000 , pendingIntent);  //set repeating every year
