1.先導入函示庫(build.gradle: Module)

dependencies {
     implementation 'com.contrarywind:Android-PickerView:4.1.9'
}

2.自定義需要三個陣列顯示

private ArrayList<String> year = new ArrayList<>();
private ArrayList<String> month = new ArrayList<>();
private ArrayList<String> day = new ArrayList<>();
private int nowYear;
private int nowMonth;
private int nowDay;

private void getAllDate() {
    Calendar calendar = Calendar.getInstance();
    nowYear = calendar.get(Calendar.YEAR) - 1911;
    for (int i = 1; i <= nowYear; i++) {
        year.add("民國" + i + "年");
    }

    nowMonth = calendar.get(Calendar.MONTH) + 1;
    for (int i = 1; i <= 12; i++) {
        month.add(i + "月");
    }

    nowDay = calendar.get(Calendar.DAY_OF_MONTH);
    for (int i = 1; i <= 31; i++) {
        day.add(i + "日");
    }
}

3.創建自定義PickerView

DatePicker = new OptionsPickerBuilder(this, new OnOptionsSelectListener() {
        @Override
        public void onOptionsSelect(int options1, int options2, int options3, View v) {
            String year = String.valueOf((options1+1));
            String month = String.valueOf((options2+1));
            String day = String.valueOf((options3+1));

            if (year.length() < 3) {
                year = "0" + year;
            } else if (month.length() == 1) {
                month = "0" + month;
            } else if (day.length() == 1) {
                day = "0" + day;
            }
            date.setText( year + "/" + month + "/" + day);
            year.clear();
            month.clear();
            day.clear();
        }
    })
            .setOptionsSelectChangeListener(new OnOptionsSelectChangeListener() {
                @Override
                public void onOptionsSelectChanged(int options1, int options2, int options3) {
                    Calendar calendar = Calendar.getInstance();
                    //用西元年跟月 去換最大的天數
                    calendar.set(Calendar.YEAR, options1 + 1912);
                    calendar.set(Calendar.MONTH, options2);
                    calendar.set(Calendar.DAY_OF_MONTH, calendar.getActualMaximum(Calendar.DAY_OF_MONTH));
                    //只抓取天
                    @SuppressLint("SimpleDateFormat") DateFormat formatter = new SimpleDateFormat("dd");
                    String endDate = formatter.format(calendar.getTime());
                    changeTheDay(Integer.parseInt(endDate), options1, options2, options3);
                }
            })
            .setSubmitText("確定")
            .setContentTextSize(20)
            .build();
    DatePicker.setNPicker(year, month, day);
    DatePicker.setSelectOptions(nowYear, nowMonth - 1, nowDay);
    DatePicker.show();
    constraintLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            DatePicker.show();
        }
    });

4.自動判斷天數

private void changeTheDay(int thisDay, int options1, int options2, int options3) {
    day.clear();
    for (int i = 1; i <= thisDay; i++) {
        day.add(i + "日");
    }
    DatePicker.setNPicker(year, month, day);
    DatePicker.setSelectOptions(options1, options2, options3);
}
