日程倒计时界面：主界面主要实现的是倒计时的功能，输入倒计时的时间后点击确定按钮，下方的方块即会显示倒计时时间，时间到后手机会震动及振铃。点击方块后取消提醒。

int hour = 0, minute = 0, second = 0;

if (!TextUtils.isEmpty(etHour.getText().toString())) {

hour = Integer.valueOf(etHour.getText().toString());

}

if (!TextUtils.isEmpty(etMinute.getText().toString())) {

minute = Integer.valueOf(etMinute.getText().toString());

}

if (!TextUtils.isEmpty(etSecond.getText().toString())) {

second = Integer.valueOf(etSecond.getText().toString());

}

int sum = hour * 1000 * 3600 + minute * 1000 * 60 + second * 1000;

if (sum == 0) {

Toast.makeText(getActivity(), "请输入倒计时时间!", Toast.LENGTH_SHORT).show();

} else {

mc = new MyCount(sum, 1000);

mc.start();

}

etMinute.setText("");

etHour.setText("");

etSecond.setText("");

通知栏提醒界面：主界面主要实现的是在日程提醒的状态下通知栏展示提醒的日程，点击该通知栏后可进入日程查看界面。

Notification.Builder builder = new Notification.Builder(this);

notificationManager = (NotificationManager) this

.getSystemService(NOTIFICATION_SERVICE);

Intent clickIntent = new Intent(NotificationService.this, MyReceiver.class);

clickIntent.putExtra("id", id);

PendingIntent pendingIntent = PendingIntent.getBroadcast(NotificationService.this, 1, clickIntent, PendingIntent.FLAG_CANCEL_CURRENT);

builder.setTicker("您有设定日程已到时间").setDefaults(Notification.DEFAULT_VIBRATE).setContentIntent(pendingIntent).setSmallIcon(R.mipmap.android).setContentTitle("日程提示")

.setContentText("点击查看日程: " + title);

Notification notification = builder.build();

notificationManager.notify(1, notification);
