Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main. xml. In the above code, we have given text view, it going to print the current date on the window manager.
Dates are formatted using the following format: "yyyy-MM-dd'T'hh:mm:ss'Z'" if in UTC or "yyyy-MM-dd'T'hh:mm:ss[+|-]hh:mm" otherwise. On the contrary to the time zone, by default the number of milliseconds is not displayed. However, when displayed, the format is: "yyyy-MM-dd'T'hh:mm:ss.
You can use SimpleDateFormat to specify the pattern you want:
new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").format(new java.util.Date())
However, if you just want to know whether the time difference is within a certain threshold, you should probably just compare long values. If your threshold is 5 minutes, then this is 5 * 60 * 1000 milliseconds so you can use the same SimpleDateFormat by calling it's parse method and check the long values.
Example:
new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").parse("2013-10-13 14:54:03").getTime()
