Custom Date Time picker using NumberPicker and Fra

问题:

I want to a custom Date Time Picker Dialog exactly as shown in the image.

In my project this is dialog is shown when clicked on a TextView which is in a Fragment. I know that I need to use NumberPickers which populates the dates From Current date till all the dates next week.

The default android date and time pickers doesnt fit my required so I need to create my own custom `DateTimePicker fragmentDialog'.

My required DateTimePicker
