android - Avoid future dates when validating birthdates -

i'm trying birthdate in form of "mm/dd/yyyy", , want consider "future" dates invalid.

here's code far:

final calendar c = calendar.getinstance(); mday = c.get(calendar.day_of_month); mmonth = c.get(calendar.month); myear = c.get(calendar.year);  //string db=bdate.gettext().tostring();  bdate.setonclicklistener(new view.onclicklistener() {   @override     public void onclick(view v) {        showdialog(date_dialog_id);     }   });   updatedisplay(); }  private void updatedisplay() {   // todo auto-generated method stub   this.bdate.settext(new stringbuilder()   // month 0 based add 1   .append(mday).append("-").append(mmonth + 1).append("-")   .append(myear).append(" ")); }  private datepickerdialog.ondatesetlistener mdatesetlistener = new datepickerdialog.ondatesetlistener() {   public void ondateset(datepicker view, int monthofyear, int dayofmonth,int year) {     mday = dayofmonth;     mmonth = monthofyear;     myear = year;      if (year > myear)       view.updatedate(myear,mmonth,mday);      if (monthofyear > mmonth && year == myear)       view.updatedate(myear, mmonth, mday);      if (dayofmonth > mday && year == myear && monthofyear == mmonth)       view.updatedate(mday, mmonth, myear);      updatedisplay();   } };  @override protected dialog oncreatedialog(int id) {   switch (id) {     case date_dialog_id:       return new datepickerdialog(this, mdatesetlistener,mday,mmonth,myear);     }   return null;  }  

i used textview, @ moment accepts "future" dates. how can improve validation code?

enter code herelook @ using calendar.after(calendar) method: http://developer.android.com/reference/java/util/calendar.html#after(java.lang.object)

in ondateset callback, can use returned values create new calendar object called selecteddate. then...

boolean isaftertoday = selecteddate.after(c);
