Android programming implements tool classes that convert time into a few minutes ago a few days ago and so on

This article describes an example of Android programming to transform time into a few minutes ago, a few days ago, and other forms of tool classes. Share it for your reference, as follows:

Description:

When Android developed the client, it was before the time was displayed, such as 10 minutes ago, 8 hours ago, 1 month ago and so on. A tool class is provided below.

Code:

public class TimeUtil {
  private final static long minute = 60 * 1000;// 1 Minutes 
  private final static long hour = 60 * minute;// 1 Hours 
  private final static long day = 24 * hour;// 1 Days 
  private final static long month = 31 * day;//  Month 
  private final static long year = 12 * month;//  Year 
  /**
   *  Returns the date described in text 
   *
   * @param date
   * @return
   */
  public static String getTimeFormatText(Date date) {
    if (date == null) {
      return null;
    }
    long diff = new Date().getTime() - date.getTime();
    long r = 0;
    if (diff > year) {
      r = (diff / year);
      return r + " Years ago ";
    }
    if (diff > month) {
      r = (diff / month);
      return r + " Months ago ";
    }
    if (diff > day) {
      r = (diff / day);
      return r + " Days ago ";
    }
    if (diff > hour) {
      r = (diff / hour);
      return r + " Hours ago ";
    }
    if (diff > minute) {
      r = (diff / minute);
      return r + " Minutes ago ";
    }
    return " Just now ";
  }
}
