android - सोमवार से एक कैलेंडर शुरू करें



calendar (0)

मुझे इंटरनेट पर यह कैलेंडर मिल गया है और मैं इसे रविवार के बजाय सोमवार से शुरू करना चाहता हूं ... किसी भी विचार? यहां एक स्रोत है: http://droidwalk.blogspot.it/2012/11/android-calendar-sample.html CalendarView.java

                        // marker.
