This library is a custom Number Picker. provides a compound view for picking the number of items selected. It has increment and decrement options. Minimum and maximum limits for the selected value can also be set in the xml file using the custom attributes app:minlimit and app:maxlimit. You can now set the value of the number picker or retrieve its value using the methods setValue and getValue. e.g. counterView.setValue(5) or int count = counterView.getValue()
