希望这项工作为您

public void startCalenderr(View view) {

    if(calendar1 == null){
        calendar1 = Calendar.getInstance();
    }
    if(curYear <1)curYear = calendar1.get(Calendar.YEAR);
    if(curMonth < 1)curMonth = calendar1.get(Calendar.MONTH);
    if(curDay < 1)curDay = calendar1.get(Calendar.DAY_OF_MONTH);

    //this is the dialog for the date picker

    dialog = new DatePickerDialog(Main2Activity.this, new DatePickerDialog.OnDateSetListener() {
        @Override
        public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
            // here i set my date into text view
            month += 1;

            String converdate  = year+"-"+month+"-"+dayOfMonth;

            curYear = year;
            curMont = month;
            curDay = dayOfMonth;
        }, curYear, curMonth, curDay);
             dialog.show();
        // here i show my datepicker dialog 
    }

设置这些参数

curYear, curMonth, curDay

在构造函数的末尾直到您喜欢的日期。
