Android使用DatePickerDialog日期控件使用主题android:Theme.Holo.Light.Dialog有白边的问题解决

改成

DatePickerDialog dialog = new DatePickerDialog(new ContextThemeWrapper(context, android.R.style.Theme_Holo_Light_Dialog_NoActionBar),listener,calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
