time comparison in two editText : android -


i have 2 edittext in enter time in , time out. googled couldn't find proper answer comparing 2 edittext having time in them. want create kind of validation function tells time in cannot less time out. eg if come office @ 09:00 cannot leave office @ 8:am

my time picker function 1 edittext :

 {                 final calendar c = calendar.getinstance();                 mhour = c.get(calendar.hour_of_day);                 mminute = c.get(calendar.minute);                  // launch time picker dialog                 timepickerdialog tpd = new timepickerdialog(this,                         new timepickerdialog.ontimesetlistener() {                              @override                             public void ontimeset(timepicker view, int hourofday,                                     int minute) {                                 // display selected time in textbox                                 txttime.settext(string.format("%02d:%02d", hourofday, minute));                             }                         }, mhour, mminute, false);                 tpd.show();               } 

public boolean timevalidator(string time1, string time2) {          simpledateformat sdf = new simpledateformat("hh:mm");         boolean b = false;         try {             java.util.date arrtime = sdf.parse(time1);             java.util.date deptime = sdf.parse(time2);               // function check whether time after time             b = deptime.after(arrtime);         } catch (parseexception e) {             // todo auto-generated catch block             e.printstacktrace();         }          return b;     }

provide values of edittexts in function parameters. there has been ".after" method used in snippet, 1 - ".before" can used well.

check :

if(timevalidator(et1.gettext().tostring(), et2.gettext().tostring()) { // } else { // }
