I have got a TimePickerDialog working to set time which is set to a TextView in order to display it. Now, I need help to set that TimePicker (inside the TimePickerDialog) minutues interval to 15 minutes. I have seen there is a post with 15 minutes interval issue related to TimePicker, but I don't know how to apply it to the TimePickerDialog because I don't know how to use the TimePicker that it is created inside the TimePickerDialog. I am new to Android and completely lost in this matter. Thanks in advance.
