Android使用警报管理器在特定时间推送通知

Question

我想在一段时间内使用推送通知。我正在使用这些代码；

这是我的AlarmReceiver课程：

public class AlarmReceiver extends BroadcastReceiver {

private static int NOTIFICATION_ID = 1;

@Override
public void onReceive(Context context, Intent intent) {
    NotificationManager manger = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Notification notification = new Notification(R.drawable.arrrow_icon,
            "test", System.currentTimeMillis());

    PendingIntent contentIntent = PendingIntent.getActivity(context,
            NOTIFICATION_ID, new Intent(context, AlarmReceiver.class),0);

    Bundle extras = intent.getExtras();
    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);

}
};

这是我的主要班级的一部分；

意图alarmintent =新意图(getApplicationContext()，AlarmReceiver.class)；alarmintent.putExtra(“标题”，“测试”)；alarmintent.putExtra(“注意”，“测试消息”)；PendingIntent发送方= PendingIntent .getBroadcast(getApplicationContext()，1，alarmintent，PendingIntent.FLAG_UPDATE_CURRENT \ Intent.FILL_IN_DATA)；

AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE)；am.set(AlarmManager.RTC_WAKEUP，cal.getTimeInMillis()，发件人)；

如果我的应用程序是向后工作的，当我强制关闭通知不起作用时，推送通知是工作的correctly.but。谢谢你帮忙。

这可能对你有帮助。首先，将此代码用于您的警报接收类。

public class AlarmReceiver extends BroadcastReceiver
{
    NotificationManager nm;
    public void onReceive(Context context, Intent intent) 
    {
        Toast.makeText(context, "Log Out !!", Toast.LENGTH_LONG).show();
//      Vibrator vibrator=(Vibrator)context.getSystemService(Context.VIBRATOR_SERVICE);
//      vibrator.vibrate(1000);
        nm=(NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
        CharSequence ch="Log Out Service";
        CharSequence message="Log Out You have to login again!! ";
        Notification notif = new Notification(R.drawable.ic_launcher,
                    "You Are Logged out...", System.currentTimeMillis());
//       PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
//                  new Intent(), 0);
         Intent notifyintent=new Intent(context,AlarmManagerTestActivity.class);
         PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, 
            notifyintent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
         notif.flags |=Notification.FLAG_AUTO_CANCEL;
                  notif.setLatestEventInfo(context, ch, message, pendingIntent);
                  nm.notify(0, notif);        
         }
    }

然后将这些代码放入您的活动中。

Intent intent = new Intent(your activity,AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
AlarmManagerTestActivity.this, 0, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pendingIntent);

然后尝试使用此代码，将此代码从onCreate()受保护的void onUserLeaveHint() { // TODO自动生成的方法存根super.onUserLeaveHint()；exitAppAnimate()；}中删除。

private void exitAppAnimate() {
    ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    List<RunningTaskInfo> recentTasks = activityManager
            .getRunningTasks(Integer.MAX_VALUE);
    for (int i = 0; i < recentTasks.size(); i++) {
        if (i == 1
                && recentTasks.get(i).baseActivity.toShortString().indexOf(
                        getPackageName()) > -1) {
            // home button pressed
            IShomepressed = true;
            System.out.println("Home buttonpressed..........");

            // android.os.Process.killProcess(android.os.Process.myPid());
            break;
        }
    }
}  and put this if (IShomepressed) {
        IShomepressed = false;

在那里使用挂起的intent.this将对您有所帮助。
