The TimePicker mode is set using the вЂњandroid:timePickerModeвЂќ attribute on the TimePicker which can be set to either вЂњspinnerвЂќ or вЂњclockвЂќ.Д«y default the spinner mode shows the hour, the minute and whether it is an AM or PM time. The TimePicker widget supports two different modes a spinner mode and clock mode, I have selected a spinner mode. The fragment layout contains a TimePicker widget. Check out the sample fragment layout I have created below.

Whether it is a recurring alarm or a once off alarm, and if it is a recurring alarm which days of the week the alarm will be activeДЇirst we will create a layout resource for the fragment.A title for the alarm which will be shown in the notification when the alarm is playing.We will be creating a fragment called вЂњCreateAlarmFragmentвЂќ which will be used for capturing all the details needed for the alarm such as: In the first section of the tutorial I will show you how we will be capturing the time for the alarm to go off using a TimePicker widget. If you would like to learn more about the MVVM design pattern and how it can be used in apps that require integration with an API, check out the following post that I wrote.Дў9 Jetpack Components That Can Help You Craft Better Android Apps Tutorial for Creating a Simple Alarm Clock App in Android Step 1: Capturing the Alarm Time using a TimePicker
