How to obtain whether the system time is in the 24-hour or 12-hour format

When creating a project, because the display time is required, the display format must be the same as the time format displayed in the system title bar. I haven't found any documentation on the internet for a long time, later I saw it in a book.

Source code:

Contentresolver CV = This. getcontentresolver ();
String strtimeformat = Android. provider. settings. system. getstring (CV,
Android. provider. settings. system. time_12_24 );

If (strtimeformat. Equals ("24 "))

{
Log. I ("activity", "24 ");
}

These tips sometimes take a long time to find and hope to be useful to people in need.
