释放双眼，带上耳机，听听看~！

一、创建定时器

设置权限

案例

https://developer.android.com/reference/android/provider/AlarmClock.html#EXTRA_MESSAGE

public void createAlarm(String message, int hour, int minutes) {

Intent intent = new Intent(AlarmClock.ACTION_SET_ALARM)

.putExtra(AlarmClock.EXTRA_MESSAGE, message)

.putExtra(AlarmClock.EXTRA_HOUR, hour)

.putExtra(AlarmClock.EXTRA_MINUTES, minutes);

if (intent.resolveActivity(getPackageManager()) != null) {

startActivity(intent);

}

}

可重复闹铃

EXTRA_DAYS

一个 ArrayList，其中包括应重复触发该闹铃的每个周日。 每一天都必须使用 Calendar 类中的某个整型值(如 MONDAY)进行声明。

对于一次性闹铃，无需指定此 extra。

参考

https://developer.android.google.cn/guide/components/intents-common.html?hl=zh-cn#Clock

创建系统定时器

public void startTimer(String message, int seconds) {

Intent intent = new Intent(AlarmClock.ACTION_SET_TIMER)

.putExtra(AlarmClock.EXTRA_MESSAGE, message)

.putExtra(AlarmClock.EXTRA_LENGTH, seconds)

.putExtra(AlarmClock.EXTRA_SKIP_UI, true);

if (intent.resolveActivity(getPackageManager()) != null) {

startActivity(intent);

}

}

二、添加日历事件

添加权限

添加日历事件

https://developer.android.com/reference/android/provider/AlarmClock.html#EXTRA_MESSAGE

public void addEvent(String title, String location, Calendar begin, Calendar end) {

Intent intent = new Intent(Intent.ACTION_INSERT)

.setData(Events.CONTENT_URI)

.putExtra(Events.TITLE, title)

.putExtra(Events.EVENT_LOCATION, location)

.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, begin)

.putExtra(CalendarContract.EXTRA_EVENT_END_TIME, end);

if (intent.resolveActivity(getPackageManager()) != null) {

startActivity(intent);

}

}

三、通过ContentProvider设置日历

uri matcher

private static String CALANDER_URL = "content://com.android.calendar/calendars";

private static String CALANDER_EVENT_URL = "content://com.android.calendar/events";

private static String CALANDER_REMIDER_URL = "content://com.android.calendar/reminders";

插入

/**

* 增加日历提醒事件

* @param activity

* @param dataEntity

* @param isRecord

* @return

*/

public static boolean addCalendarReminder(Activity activity,DataEntity dataEntity, boolean isRecord){

if (!AactivityCompat.hasPermissions(activity, Manifest.permission.WRITE_CALENDAR, Manifest.permission.READ_CALENDAR)) {

return false;

}

try {

// Calendar startCalendar = Calendar.getInstance();

// long startTime = startCalendar.getTimeInMillis() + 8 * 60 * 1000;

long startTime = dataEntity.getRemind_time();

// Calendar endCalendar = Calendar.getInstance();

// long endTime = endCalendar.getTimeInMillis() + 50 * 60 * 1000;

long endTime = startTime + 10 * 60 * 1000;

String remindTitle = dataEntity.getTitle();

// 日历事件

ContentValues calEvent = new ContentValues();

calEvent.put(CalendarContract.Events.CALENDAR_ID, 1); // XXX pick)

calEvent.put(CalendarContract.Events.TITLE, remindTitle);

calEvent.put(CalendarContract.Events.DTSTART, startTime);

calEvent.put(CalendarContract.Events.DTEND, endTime);

calEvent.put(CalendarContract.Events.HAS_ALARM, 1);

calEvent.put(CalendarContract.Events.EVENT_TIMEZONE, CalendarContract.Calendars.CALENDAR_TIME_ZONE);

ContentResolver cr = activity.getContentResolver();

if (null == cr) {

return false;

}

try {

Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, calEvent);

if (null == uri) {

return false;

}

int eventId = Integer.parseInt(uri.getLastPathSegment());

/** 记录code 记录eventId **/

if (isRecord) {

saveEventCode(dataEntity.getProduct_code());

saveEventId(eventId);

}

// 日历提醒

ContentValues reminders = new ContentValues();

reminders.put(CalendarContract.Reminders.EVENT_ID, eventId);

reminders.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);

reminders.put(CalendarContract.Reminders.MINUTES, REMIND_MINUTES);

cr.insert(CalendarContract.Reminders.CONTENT_URI, reminders);

return true;

} catch (SecurityException ignore) {}

} catch (Exception ignore) {}

return false;

}
