Answer 1

this snippet explain when we compare two dates in string formats, in other words to date is not allowed when greater than from date.

 private void setTodate() {
            // TODO Auto-generated method stub
            // Process to get Current Date
            int fYear, fMonth, fDay;
            final Calendar c = Calendar.getInstance();
            fYear = c.get(Calendar.YEAR);
            fMonth = c.get(Calendar.MONTH);
            fDay = c.get(Calendar.DAY_OF_MONTH);
            // Launch Date Picker Dialog
            DatePickerDialog dpd = new DatePickerDialog(RemindMeDetails.this,
                    new DatePickerDialog.OnDateSetListener() {
                        @SuppressLint("SimpleDateFormat")
                        @Override
                        public void onDateSet(DatePicker view, int year,
                                int monthOfYear, int dayOfMonth) {                  
                        try{                        
                            SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");        
                            String fdate=recr_edit_Fromdate.getText().toString();                       
                            Date dateFD = formatter.parse(fdate);                       
                            String tdate=(dayOfMonth + "-"
                                    + (monthOfYear + 1) + "-" + year).toString();
                            Date dateTD = formatter.parse(tdate);                       
                            if (dateFD.compareTo(dateTD)<=0)
                              {
                                /* System.out.println("tdate is Greater than my fdate");  
                                 recr_edit_Todate.setText(dayOfMonth + "-"
                                            + (monthOfYear + 1) + "-" + year);*/
                                recr_edit_Todate.setText(tdate);
                              }
                            else{
                                showmessage("Alert", "Start date is not greater than End date");                            
                        }catch (ParseException e1){
                            e1.printStackTrace();
                        }   
                        }
                    }, fYear, fMonth, fDay);
            dpd.show();
        }// method closed
