Acquisition of system date and time in Android

1. ImportJava. Text. simpledateformat; Simpledateformat formatter =NewSimpledateformat ("Yyyy-mm-dd hh: mm: SS"); Date curdate =NewDate (system. currenttimemillis ());// Obtain the current time String STR = formatter. Format (curdate ); You can obtain the current date and month, or write separately: [Java] View plaincopyprint? Simpledateformat sdateformat =NewSimpledateformat ("Yyyy-mm-dd hh: mm: SS"); String date = sdateformat. Format (NewJava. util. Date ());   If you want to obtain the current year and month, you can write it like this (only get the same time or second ): JavaCode [Java] View plaincopyprint? Simpledateformat SDF =NewSimpledateformat ("Yyyy-mm"); String date = SDF. Format (NewJava. util. Date ());   Of course, you can also specify the time zone (to be ): [Java] View plaincopyprint? DF = dateformat. getdatetimeinstance (dateformat. Full, dateformat. Full, locale. China ); System. Out. println (DF. Format (NewDate ()));
