我正在使用報警管理器和廣播接收器設置通知。我試圖使用警報管理器的setInexactRepeating方法，但它不會在API 19上方的確切時間上報警。如何使用setExact設置重複鬧鈴以及如何取消同樣的動作？
所以我建議使用setExact方法並手動設置警報。我不知道我該怎麼做。我是否需要計算一年中每週的日期？
此外，我正在創建的報警我想刪除相同的，如果事件被刪除。我怎樣才能取消這個？使用取消方法我試圖取消警報。爲了測試，我嘗試設置多個警報並將其刪除。
如果我刪除了一個事件，那麼該事件的重要警報應該取消，但可能所有警報都會取消，因爲我在刪除事件後沒有收到任何通知。
我爲此使用了唯一標識。作爲最終的靜態int RQS_1 = 1;用於設置警報。
任何人都可以幫我解決這個問題嗎？
設置鬧鐘：
public void setNotificationTime(Calendar c)
{
Date dateFrom = new Date();
df = new SimpleDateFormat("E MMM dd hh:mm:ss zzzz yyyy");
try {
dateFrom = df.parse(startTime);
}
catch (ParseException ex) {
}
dateFrom.getTime();
c.setTime(dateFrom);
hour = c.get(Calendar.HOUR_OF_DAY);
minute = c.get(Calendar.MINUTE);
if(notificationTime.equals("10 Minutes Before"))
{
c.set(Calendar.HOUR_OF_DAY, hour);
c.set(Calendar.MINUTE, minute - 10);
c.set(Calendar.SECOND, 0);
c.set(Calendar.MILLISECOND, 0);
c.set(Calendar.DATE, day);
// c.set(Calendar.DAY_OF_WEEK,);
SetDay(c);
notification = c.getTime();
notificationTime = df.format(notification);
Toast.makeText(getApplicationContext(),notificationTime,Toast.LENGTH_SHORT).show();
intent = new Intent(getBaseContext(),NotificationReceiver.class);
pendingIntent = PendingIntent.getBroadcast(getBaseContext(),RQS_1, intent, 0);
alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 7, pendingIntent);
}
else if(notificationTime.equals("30 Minutes Before"))
{
c.set(Calendar.HOUR_OF_DAY, hour);
c.set(Calendar.MINUTE, minute - 30);
c.set(Calendar.SECOND, 0);
c.set(Calendar.MILLISECOND, 0);
c.set(Calendar.DATE, day);
// c.set(Calendar.DAY_OF_WEEK,);
SetDay(c);
notification = c.getTime();
notificationTime = df.format(notification);
Toast.makeText(getApplicationContext(),notificationTime,Toast.LENGTH_SHORT).show();
intent = new Intent(getBaseContext(),NotificationReceiver.class);
pendingIntent = PendingIntent.getBroadcast(getBaseContext(),RQS_1, intent, 0);
alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 7, pendingIntent);
}
}
setDay方法我已經創建設置已經從一個對話框，設置日choosen用戶一天。
setDay功能：
public void SetDay(Calendar c)
{
switch (dayOfWeek)
{
case "Mon":
c.set(Calendar.DAY_OF_WEEK, 2);
c.getTime();
Toast.makeText(getApplicationContext(),dayOfWeek,Toast.LENGTH_SHORT).show();
break;
case "Tue":
c.set(Calendar.DAY_OF_WEEK, 3);
c.getTime();
Toast.makeText(getApplicationContext(),dayOfWeek,Toast.LENGTH_SHORT).show();
break;
}
通知接收
public class NotificationReceiver extends BroadcastReceiver {
public static int MY_NOTIFICATION_ID = 0;
NotificationManager notificationManager;
Notification myNotification;
EventTableHelper db;
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Time is set", Toast.LENGTH_LONG).show();
db = new EventTableHelper(context);
List<EventData> testSavings = db.getAllEvents();
for (EventData ts : testSavings) {
String log = "from date:" + ts.getFromDate()
+ " ,to date: " + ts.getToDate()
+ " ,location: " + ts.getLocation()
+ " ,title " + ts.getTitle();
Calendar c = Calendar.getInstance();
Date date = new Date();
Date date1 = new Date();
Log.d("Result: ", log);
SimpleDateFormat df = new SimpleDateFormat("E MMM dd hh:mm:ss zzzz yyyy");
SimpleDateFormat df2 = new SimpleDateFormat("hh:mm a");
try {
date = df.parse(ts.getFromDate());
date1 = df.parse(ts.getToDate());
} catch (ParseException ex) {
}
String timeFrom = df2.format(date);
// String startTime = String.valueOf(timeFrom);
String timeTo = df2.format(date1);
// String endTime = String.valueOf(timeTo);
String location = ts.getLocation();
String title = ts.getTitle();
Intent myIntent = new Intent(context, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(
context,
0,
myIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
if(location.equals(""))
{
String msg = "From : " + timeFrom + "\nTo : " + timeTo;
myNotification = new NotificationCompat.Builder(context)
.setContentTitle("Event : " + title)
.setContentText(msg)
.setWhen(System.currentTimeMillis())
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.setSmallIcon(R.drawable.eventicon)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setDefaults(Notification.DEFAULT_SOUND)
.build();
}
else
{
String msg = "From : " + timeFrom + "\nTo : " + timeTo + "\nAt : " + location;
myNotification = new NotificationCompat.Builder(context)
.setContentTitle("Event : " + title)
.setContentText(msg)
.setWhen(System.currentTimeMillis())
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.setSmallIcon(R.drawable.eventicon)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setDefaults(Notification.DEFAULT_SOUND)
.build();
}
Log.i("Notify", "Notification");
notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(MY_NOTIFICATION_ID, myNotification);
myNotification.flags=Notification.FLAG_AUTO_CANCEL;
}
}
}
是忘了添加的代碼取消：
alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
intent = new Intent(getApplicationContext(), NotificationReceiver.class);
pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), RQS_1, intent, 0);
alarmManager.cancel(pendingIntent);
謝謝。
是的，我已經做了同樣的..Please檢查編輯問題。那麼這是否會刪除尊重的警報？或所有警報？ @Madhur – Sid
它會刪除任何與匹配意圖警報檢查了這一點http://developer.android.com/reference/android/app/AlarmManager.html#cancel(android.app.PendingIntent） – Madhur
我的代碼是否正確設置報警？我怎樣才能使用setExact方法設置？ – Sid
