Android 安卓警报通知
我正在尝试在我的移动应用程序中实现报警功能。下面是我的用例Android 安卓警报通知,android,notifications,alarm,Android,Notifications,Alarm,我正在尝试在我的移动应用程序中实现报警功能。下面是我的用例 用户可以从活动“A”设置提醒设置提醒设置提醒后,用户将在设置时间前10分钟收到通知。现在,用户可以从另一个活动中删除提醒,假设“B” 除此之外,我还希望用户可以从通知窗口重新安排他/她的提醒设置 下面是我为用例1编写的代码 private void setAlarm(){ Intent intent = new Intent(A.this, RepeatAlarm.class); mAlarmSender = Pend
private void setAlarm(){
Intent intent = new Intent(A.this, RepeatAlarm.class);
mAlarmSender = PendingIntent.getService(A.this,
0, new Intent(A.this, RepeatAlarm.class), 0);
// We want the alarm to go off 30 seconds from now.
long firstTime = SystemClock.elapsedRealtime();
// Schedule the alarm!
AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
firstTime, 30*1000, mAlarmSender);
// Tell the user about what we did.
Toast.makeText(A.this, R.string.repeating_scheduled,
Toast.LENGTH_LONG).show();
}
private void stopAlarm(){
// And cancel the alarm.
AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
am.cancel(mAlarmSender);
// Tell the user about what we did.
Toast.makeText(B.this, R.string.repeating_unscheduled,

现在我尝试尝试第二种情况,因为我在通知布局上放置了两个按钮,称为“重新安排”和“取消”,但在这种情况下,我的视图没有显示在通知窗口中,我在谷歌上搜索了过去两天,但没有运气,现在这对我来说是非常令人担忧的情况,我必须在一天结束前以任何方式完成它。因此,任何建议或解决方法都将对我非常有帮助
谢谢
Ashish除了你发布的代码之外,你还试过其他东西吗?您是否在调试器中运行了代码?正在调用showNotification()方法吗?您是否尝试过显示一个简单的通知?除了您发布的代码之外,您是否尝试过其他内容?您是否在调试器中运行了代码?正在调用showNotification()方法吗?是否尝试显示一个简单的通知?
