在我的应用程序中，当我删除提醒（同时为多个事件设置提醒）时，提醒警报会在预定时间后一小时后出现。有人面临同样的问题吗？有没有人对此有解决方案。在我在应用程序中使用的代码下方
通知接收器页面
public class NotificationReceiver extends BroadcastReceiver {
//private static int NOTIFICATION_ID = 1;
private static int NOTIFICATION_ID;
@SuppressWarnings("deprecation")
@Override
public void onReceive(Context context, Intent intent)
{
Bundle extras=intent.getExtras();
NotificationManager manger = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher, "Combi Note",System.currentTimeMillis());
NOTIFICATION_ID=Integer.parseInt(extras.getString("ID"));
PendingIntent contentIntent = PendingIntent.getActivity(context,NOTIFICATION_ID,new Intent(context, NotificationReceiver.class), 0);
String title=extras.getString("title");
String note=extras.getString("note");
notification.setLatestEventInfo(context, note, title, contentIntent);
notification.flags = Notification.FLAG_INSISTENT;
notification.defaults |= Notification.DEFAULT_SOUND;
manger.notify(NOTIFICATION_ID, notification);
}
对于通知集页面
在页面中，Button用于设置提醒
btnRemind.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
try
{
SimpleDateFormat curFormater = new SimpleDateFormat("dd/MM/yy hh:mm aa");
String s=StartTime;
//dateObj1 = curFormater.parse(StartTime);
dateObj1 = curFormater.parse(StartTime);
//SimpleDateFormat postFormater = new SimpleDateFormat("dd/MM/yy H:mm:ss.SSS");
SimpleDateFormat postFormater = new SimpleDateFormat("dd/MM/yy H:mm");
Date date2 = postFormater.parse(postFormater.format(dateObj1));
Calendar cl=Calendar.getInstance();
cl.setTime(date2);
MONTH=cl.get(Calendar.MONTH);
YEAR=cl.get(Calendar.YEAR);
DAY=cl.get(Calendar.DAY_OF_MONTH);
HOUR=cl.get(Calendar.HOUR_OF_DAY);
if(cl.get(Calendar.MINUTE)>5)
cl.add(Calendar.MINUTE, -5);
else
{
cl.add(Calendar.HOUR, -1);
cl.add(Calendar.MINUTE, -5);
}
MINUTE=cl.get(Calendar.MINUTE);
}
catch (Exception e)
{
e.printStackTrace();
}
Calendar cal=Calendar.getInstance();
cal.set(Calendar.MONTH, MONTH);
cal.set(Calendar.YEAR, YEAR);
cal.set(Calendar.DAY_OF_MONTH, DAY);
cal.set(Calendar.HOUR_OF_DAY, HOUR);
cal.set(Calendar.MINUTE, MINUTE);
Intent alarmintent = new Intent(getApplicationContext(), NotificationReceiver.class);
alarmintent.putExtra("note",txtEvent.getText()+" starts in 5 minutes on channel " +Channel);
boolean chkReminder=new DatabaseHelper(getApplicationContext()).checkReminders(Channel+" : "+txtEvent.getText().toString(), dateObj1);
if(chkReminder)
{
Toast.makeText(getApplicationContext(), "Reminder is already Set for this event !!", Toast.LENGTH_LONG).show();
}
else
{
//new DatabaseHelper(getApplicationContext()).addReminder(Channel+" : "+txtEvent.getText().toString(), dateObj1);
int ID = Integer.parseInt(strEventID);
new DatabaseHelper(getApplicationContext()).addReminder(String.valueOf(ID), Channel+" : "+txtEvent.getText().toString(), dateObj1);
//Random r = new Random();
//int ID = r.nextInt();
alarmintent.putExtra("ID", strEventID);
PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(),ID,alarmintent,PendingIntent.FLAG_UPDATE_CURRENT| Intent.FILL_IN_DATA);
AlarmManager am = (AlarmManager) getApplicationContext().getSystemService("alarm");
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);
Toast.makeText(getApplicationContext(), "Reminder Set !!", Toast.LENGTH_LONG).show();
//btnRemind.setVisibility(View.INVISIBLE);
}
}
});
}
对于在它提出之前删除提醒我使用：
private void checkButtonClick()
{
ImageButton btnDelete=(ImageButton) findViewById(R.id.imgbtnDelete);
btnDelete.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
StringBuffer responseText = new StringBuffer();
responseText.append("The following reminder is deleted from the list...\n");
String strRmDt="";
String strChannel="";
ArrayList<States> stateList = dataAdapter.stateList;
String strID="";
for(int i=0;i<stateList.size();i++)
{
States state = stateList.get(i);
if(state.isSelected())
{
try
{
//String reminder=stateList.get(i).toString();
String reminder=state.name;
String[] separated = reminder.split(" - ");
String[] strSep2 = separated[0].toString().split(" :: ");
new DatabaseHelper(getApplicationContext()).removeReminder(strSep2[0].toString());
// delete notification alarm
@SuppressWarnings("unused")
SimpleDateFormat curFormater = new SimpleDateFormat("dd/MM/yy hh:mm aa");
strRmDt=separated[1];
//String stEvent=separated[0].toString();
strID=strSep2[0].toString();
int ID=Integer.parseInt(strID);
Intent I = new Intent(getBaseContext(),NotificationReceiver.class);
I.setAction(String.valueOf(ID));
PendingIntent pIntent = PendingIntent.getBroadcast(getBaseContext(), ID, I, PendingIntent.FLAG_CANCEL_CURRENT);//.getBroadcast(getApplicationContext(), Integer.parseInt(strSep2[0].toString()), getIntent(), PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager am = (AlarmManager) getApplicationContext().getSystemService("alarm");
am.cancel(pIntent);
pIntent.cancel();
/*
AlarmManager am = (AlarmManager) getSystemService(getApplicationContext().ALARM_SERVICE);
Intent I = new Intent(getApplicationContext(),NotificationReceiver.class);
PendingIntent P = PendingIntent.getBroadcast(getApplicationContext(), Integer.parseInt(strSep2[0].toString()), I, 0);
am.cancel(P);
P.cancel();
*/
// end delete notification alarm
}
catch(Exception e)
{
System.out.print(e.getMessage());
e.printStackTrace();
}
}
}
Toast.makeText(getApplicationContext(),
responseText, Toast.LENGTH_LONG).show();
onRestart();
}
});
//RemindersListView.setAdapter(dataAdapter);
}
伙计们请帮助我
提前致谢。
