I have two EditText's. One with start date and other with end date. I need to make a validation and check if end date is greater than start-date. I don't know how i can do this.
In my code i make the difference bettween two dates in days, and now i also need to check if end date is greater than start-date
Here is my code:
//EditText with string of start date
dataInicio = (EditText)findViewById(R.id.ses_dpDataIni);
//EditText with string of end date
dataFim = (EditText)findViewById(R.id.ses_dpDataFim);
//Convert String to calendar to check the difference between two dates..
try{
dateInic = dataInicio.getText().toString();
dateFim = dataFim.getText().toString();
calInic=Calendar.getInstance();
calFim = Calendar.getInstance();
calInic.setTime(form.parse(dateInic));
calFim.setTime(form.parse(dateFim));
}
catch (ParseException e) {
e.printStackTrace();
}
Log.w(SessaoQuotaEdit.class.getName(),"DIFERENCA DE DIAS" +daysBetween(calInic,calFim));
tvDiasQuotas = (TextView)findViewById(R.id.ses_tvNumDiasQuota);
tvDiasQuotas.setText("NUMBER OF DAYS: " +daysBetween(calInic,calFim));
//CHECK IS END-DATE IS GREATER THAN START-DATE
.............

Can you help me? Thanks :)
setText("NUMBER OF DAYS: " +daysBetween(calInic,calFim)); //CHECK IS END-DATE IS GREATER THAN START-DATE ............. .............
Go to Solution. function dateCheck(){ let startDate = new Date($("#hero_startdate"). val()); let endDate = new Date($("#hero_enddate"). val()); if(startDate > endDate) { alert("End date need to be bigger then start date"); } } $( document ).
The date validator requires day, month and year. If you are looking for hour and time validator, HH:mm , for example, you should use the regexp validator. Below are some example of possible formats: YYYY/DD/MM.
You can pass min and max in the normal HTML input tag with format YYYY-MM-DD . This serves as min and max for date. To format the date you can use date-fns library. Check the sandbox and see once you select the start date all the previous dates are disabled.
Try this function.
public static boolean isDateAfter(String startDate,String endDate)
{
try
{
String myFormatString = "yyyy-M-dd"; // for example
SimpleDateFormat df = new SimpleDateFormat(myFormatString);
Date date1 = df.parse(endDate));
Date startingDate = df.parse(startDate);
if (date1.after(startingDate))
return true;
else
return false;
}
catch (Exception e)
{
return false;
}
}
It return true if enddate is after start date.
SimpleDateFormat dfDate = new SimpleDateFormat("yyyy-MM-dd");
public static boolean checkDates("2012-07-12", "2012-06-12)" {
boolean b = false;
try {
if(dfDate.parse(d1).before(dfDate.parse(d2)))
{
b = true;//If start date is before end date
}
else if(dfDate.parse(d1).equals(dfDate.parse(d2)))
{
b = true;//If two dates are equal
}
else
{
b = false; //If start date is after the end date
}
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return b;
}
