Android: The simplest way to implement a custom selection time-of-minute interval, non-roller mode

The current project only needs a minute interval, so the interval between hours and months did not do, Spiner have pits, do not do well, later have time to rewrite;

Interpreting parameters

private int max_limite_day = 30;//maximum selectable date
private int every_minintes_spce= 10;//minute gap
private int min_minintes_after = 15;//The current time to the last available time interval (minimum time period);

Explanation of the minimum time interval,

If the minute gap is 1, the minimum interval is 1, then the natural minute number is 1-59;

Minimum interval 15 minutes if the current time is 10:00 then the last available time is 10:20, because the minute every 10 minutes a file, 15 minutes in the second gear;

Minimum interval 15 minutes if the current time is 10:40 then the last available time is 11:00;

Minimum interval 10 minutes if the current world is 10:00, then the last available time is 11:10; 10 minutes a file;
