我在我的应用程序中使用日历,成功地在我的应用程序中实现了日历,但疑问是如何启用和禁用特定日期(例如：需要在所有月份或星期一以及所有月份的星期日仅启用星期一).

帮我解决一下
提前致谢.
解决方法:
dayVIEw = (TextVIEw) v.findVIEwByID(R.ID.date); // separates daystring into parts. String[] separatedTime = dayString.get(position).split("-"); // taking last part of date. IE; 2 from 2012-12-02 String grIDvalue = separatedTime[2].replaceFirst("^0*", ""); // checking whether the day is in current month or not. if ((Integer.parseInt(grIDvalue) > 1) && (position < firstDay)) { // setting offdays to white color. dayVIEw.setTextcolor(color.WHITE); dayVIEw.setClickable(false); dayVIEw.setFocusable(false); float Alpha = 0.55f; AlphaAnimation AlphaUp = new AlphaAnimation(Alpha, Alpha); AlphaUp.setFillAfter(true); dayVIEw.startAnimation(AlphaUp); } else if ((Integer.parseInt(grIDvalue) < 7) && (position > 28)) { dayVIEw.setTextcolor(color.WHITE); dayVIEw.setClickable(false); dayVIEw.setFocusable(false); float Alpha = 0.35f; AlphaAnimation AlphaUp = new AlphaAnimation(Alpha, Alpha); AlphaUp.setFillAfter(true); dayVIEw.startAnimation(AlphaUp); dayVIEw.setClickable(false); } else { // setting curent month's days in blue color. dayVIEw.setTextcolor(color.BLACK); float Alpha = 0.75f; AlphaAnimation AlphaUp = new AlphaAnimation(Alpha, Alpha); AlphaUp.setFillAfter(true); dayVIEw.startAnimation(AlphaUp); dayVIEw.setClickable(false); }以上是内存溢出为你收集整理的启用和禁用android中的日期全部内容，希望文章能够帮你解决启用和禁用android中的日期所遇到的程序开发问题。
