Android编程设置提醒事件的方法

2019年07月24日  | 移动技术网移动技术  | 我要评论

本文实例讲述了android编程设置提醒事件的方法。分享给大家供大家参考，具体如下：

1、启动service

intent intent = new intent(this,autotaskservice.class);
intent.putextra("reminder_event", remindermodel);
startservice(intent);

2、service file

public class autotaskservice extends service {
  private remindermodel mremindermodel = null;
  @override
  public ibinder onbind(intent intent) {
    return null;
  }
  @override
  public void oncreate() {
    super.oncreate();
  }
  @override
  public void ondestroy() {
    super.ondestroy();
  }
  @override
  public void onstart(intent intent, int startid) {
    if(intent == null)
      return;
    if(intent.hasextra("reminder_event")) {
      mremindermodel = (remindermodel) intent.getserializableextra("reminder_event");
    }
    setreminderevent();
    super.onstart(intent, startid);
  }
  /**
   * set reminder event
   */
  private void setreminderevent() {
    if(mremindermodel == null)
      return;
    if(textutils.isempty(mremindermodel.reminderstarttime))
      return;
    if(textutils.isempty(mremindermodel.remindertime))
      return;
    calendar cal = getcalendarfromdate(mremindermodel.reminderstarttime);
    string[] array = mremindermodel.remindertime.split("-");
    for(int i = 0; i < array.length; i++) {
      if(i == 0) {
        cal.set(calendar.hour_of_day, integer.parseint(array[0]));
      } else if (i == 1) {
        cal.set(calendar.minute, integer.parseint(array[1]));
      }
    }
    cal.set(calendar.second, 0);
    intent intent = new intent(autotaskservice.this, alarmreceiver.class);
    if(!textutils.isempty(mremindermodel.reminderpath)) {
      intent.putextra("reminder_pic_path", mremindermodel.reminderpath);
    }
    pendingintent pi = pendingintent.getbroadcast(this, 0, intent, pendingintent.flag_cancel_current);
   // 获取alarmmanager对象
    alarmmanager am = (alarmmanager) getsystemservice(alarm_service);
   // alarmmanager.rtc_wakeup休眠时会运行，如果是alarmmanager.rtc,在休眠时不会运行
    am.set(alarmmanager.rtc_wakeup, cal.gettimeinmillis(), pi);
  }
  /**
   * @param date format is 2012-9-18
   * @return calendar value is after set date's value
   */
  private calendar getcalendarfromdate(final string date) {
    int year = 0;
    int month = 0;
    int day = 0;
    try {
      string[] array = date.split("-");
      int[] arrayint = new int[array.length];
      for (int i = 0; i < array.length; i++) {
        arrayint[i] = integer.parseint(array[i]);
        if(i == 0) {
          year = arrayint[0];
        } else if(i == 1){
          month = arrayint[1];
        } else if(i == 2){
          day = arrayint[2];
        }
      }
    } catch (exception e) {
      e.printstacktrace();
    }
    calendar cal = calendar.getinstance();
    if(year > 0 && month >= 0 && day >= 0) {
      cal.set(year, month - 1, day);
    }
    return cal;
  }
}

3、定时接收器

public class alarmreceiver extends broadcastreceiver {
  @override
  public void onreceive(context context, intent intent) {
    string path = null;
    if(intent.hasextra("reminder_pic_path")) {
      path = intent.getstringextra("reminder_pic_path");
    }
    log.i("======> alarmreceiver", path);
    // 启动通知activity
    intent it = new intent(context, fingerpaint.class);
    it.addflags(intent.flag_activity_new_task);
    if(!textutils.isempty(path)) {
      it.putextra("reminder_pic_path", path);
    }
    context.startactivity(it);
  }
}

希望本文所述对大家android程序设计有所帮助。
