title: End-date greater than start-date validation android
body: <p>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.</p>
  
  <p>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</p>
  
  <p>Here is my code:</p>
  
  <pre><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
               .............
               .............
  </code></pre>
