获取日期和系统日期android之间的差异

Question

I am trying to achieve a functionality for a membership App but am find some difficulties working with Dates.

I retrieve a startDate from the DB which comes as "YYYY-MM-dd". What I wish to achieve is to calculate the difference in day from the currentDate to the startDate store it in a variable int result

if result > 365 textView.setText("Membership expired");

If anyone can point me in the right direction, I'll be really grateful.

您可以使用下面的代码来计算当前日期和开始日期之间的天数。

(currentDate - startDate) / (1000*3600*24)
