Summary: Today is mainly to fix yesterday ’s problem and improve the function of the alarm clock, solve the problem that activity can not jump to fragment, the solution is to jump out of the pop-up box after clicking add, the user can set the alarm time and label content It avoids adding an alarm to jump to the activity and then return to the fragment. The second problem is that the user enters the alarm clock interface to display the alarm switch status. The solution is to add a monitoring event to the switch and match it with the stored alarm status of the database to let it display the switch status. So much has been done today, and tomorrow the alarm trigger event is planned. The following is the main code and renderings of today.
