【问题描述】：
嘿，伙计们，我有文本视图，当用户点击每个文本视图时，会显示一个日期选择器。我在同一页面上有八个文本视图，它们按时间顺序排列。现在的挑战是我想要第一个日期时间选择器显示从今天开始的日期，下一个日期时间选择器应该只显示大于在第一个文本视图中选择的日期的日期。第三个还应该显示大于在第二个文本视图中选择的日期。我拥有的当前代码是
public class General extends Fragment {
TextView onlinee, orientationn, semesterstarts, semesterbreakstarts, semesterbreakends, examstarts, examends, semesterends;
Button btncalendarr;
@Override

【问题讨论】：
-
您当前的代码可以实现什么？
-
我只能用当前代码设置日期随机日期
-
日期集是格式，比如说，23/5/2016
-
setMinDate() on datepicker to your selected date 以限制 datepicker
