End-date Greater Than Start-date Validation Android

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

Solution 1:

SimpleDateFormatdfDate=newSimpleDateFormat("yyyy-MM-dd");
publicstaticbooleancheckDates("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
        }
        elseif(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;
}

Solution 2:

Try this function.

publicstaticbooleanisDateAfter(String startDate,String endDate)
    {
        try
        {
            String myFormatString = "yyyy-M-dd"; // for exampleSimpleDateFormat df = newSimpleDateFormat(myFormatString);
            Date date1 = df.parse(endDate));
            Date startingDate = df.parse(startDate);

            if (date1.after(startingDate))
                returntrue;
            elsereturnfalse;
        }
        catch (Exception e) 
        {

            returnfalse;
        }
    }

It return true if enddate is after start date.

Solution 3:

publicstaticboolean CheckDates(String d1, String d2){
    SimpleDateFormat dfDate  = new SimpleDateFormat("yyyy-MM-dd");
    boolean b = false;
    try {
        if(dfDate.parse(d1).before(dfDate.parse(d2)))
        {
            b = true;//If start date is before end date
        }
        elseif(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;
}

Solution 4:

Why not try DateUtils.getRelativeTimeSpanString?

Solution 5:

Thanks to everyone ....

Here is my solution

        if(calInic.after(calFim)==true)
        Log.w(SessaoQuotaEdit.class.getName(),"ERROR: DATA FINAL É ANTES DA DATA INICIAL");
    elseif(calInic.before(calFim)==true)
            Log.w(SessaoQuotaEdit.class.getName(),"CORRECTO: DATAS CORRECTAS");
        elseif(calInic.equals(calFim)==true)
                Log.w(SessaoQuotaEdit.class.getName(),"CORRECTO: DATAS IGUAIS");
