我的应用程序中有一个时间选择器、一个createnoificationchannel函数和一个sendnotifications函数。一切正常，但当我按下按钮时，通知会在几秒钟后生效，因为按下按钮的时间不在时间选择器选择的时间内！！。我不知道如何将时间选择器与sendnotifications函数链接。任何帮助都将不胜感激。
仅限kotlin或java。。
我的设置活动

private val CHNNEL_ID = "adthan_channel_id"
private val notificationId = 101

private lateinit var picker : MaterialTimePicker
private lateinit var calender : Calendar
private lateinit var alarmManager: AlarmManager
private lateinit var pendingIntent: PendingIntent

我的通知按钮

//صلاة الفجر

      fajrSalah.setOnCheckedChangeListener { buttonView, isChecked ->

            if (isChecked){
                showTimePicker()

                editor.putBoolean("fajrSalahChecked", isChecked)
                editor.apply()

            }else{
                editor.remove("fajrSalahChecked")
                editor.apply()

              //  cancelAlarm()
                toast("تم حذف المنبة")
            }
        }
