He creado una actividad en la que hay un campo para insertar la fecha de nacimiento del usuario. He utilizado un selector de fecha para lograr esto.

Este es el código fuente de lo que estoy haciendo:

// onclick dob edittext open date picker dialog
        dob.setFocusableInTouchMode(false);
        dob.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                //open date picker
                  showDialog(DATE_DIALOG_ID);

            }
        }); 


//======================For picking birth day==========================
    // Creating dialog
        @Override
        protected Dialog onCreateDialog(int id) {
            Calendar c = Calendar.getInstance();
            int cyear = c.get(Calendar.YEAR);
            int cmonth = c.get(Calendar.MONTH);
            int cday = c.get(Calendar.DAY_OF_MONTH);


            switch (id) {
                case DATE_DIALOG_ID:
                    return new DatePickerDialog(this, mDateSetListener, cyear, cmonth, cday);
            }
            return null;
        }
        private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
            // onDateSet method
            public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
//              String date_selected = String.valueOf(monthOfYear+1)+" /"
//                                    +String.valueOf(dayOfMonth)+" /"
//                                    +String.valueOf(year);

                String date_selected = String.valueOf(dayOfMonth)+" /"
                        +String.valueOf(monthOfYear+1)+" /"
                        +String.valueOf(year);
                //Toast.makeText(RegisterActivity.this, "Selected Date is ="+date_selected, Toast.LENGTH_SHORT).show();
                dob.setText(date_selected);
            }
        };
//======================For picking birth day==========================

Ahora lo que quiero hacer es limitar el selector de fecha a un año en particular. Me gusta esto:

int maxYear = c.get(Calendar.YEAR) - 15; // this year ( 2013 ) - 15 = 1998
                int maxMonth = c.get(Calendar.MONTH);
                int maxDay = c.get(Calendar.DAY_OF_MONTH);

                int minYear = maxYear-49;
                int minMonth = 0; // january
                int minDay = 25; 

¿Qué debo hacer para establecer el límite mencionado anteriormente al selector de fecha?

He hecho algo como esto:

//======================For picking birth day==========================
    // Creating dialog
        @Override
        protected Dialog onCreateDialog(int id) {
            Calendar c = Calendar.getInstance();
            maxYear = c.get(Calendar.YEAR) - 15; // this year ( 2013 ) - 15 = 1998
            maxMonth = c.get(Calendar.MONTH);
            maxDay = c.get(Calendar.DAY_OF_MONTH);




            switch (id) {
                case DATE_DIALOG_ID:
                    return new DatePickerDialog(this, mDateSetListener, maxYear, maxMonth, maxDay);
            }
            return null;
        }


        DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {



                int minYear = maxYear-49;
                int minMonth = 0; // january
                int minDay = 25;

            public void onDateChanged(DatePicker view, int year, int monthOfYear,int dayOfMonth) {

                Date current = new Date(year, monthOfYear, dayOfMonth);

                Date minDate = new Date(minYear, minMonth, minDay);
                Date maxDate = new Date(maxYear, maxMonth, maxDay);
                if( current.getTime() < minDate.getTime() )
                {
                    //set to minimum date
                }else if( current.getTime() > maxDate.getTime() )
                {
                    //Set to max Date
                }

            }

            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear,
                    int dayOfMonth) {
                // TODO Auto-generated method stub
                 String date_selected = String.valueOf(dayOfMonth)+" /"
                            +String.valueOf(monthOfYear+1)+" /"
                            +String.valueOf(year);
                    //Toast.makeText(RegisterActivity.this, "Selected Date is ="+date_selected, Toast.LENGTH_SHORT).show();
                    dob.setText(date_selected);

            }
        };

Esto es arreglar el límite superior, ¡pero el límite inferior o la fecha mínima no se está arreglando! ¿Lo que se debe hacer?
