@abiemann Hi, The following sample code you can be referred to :

 //The first parameter is your layout resouce id.
.setLayoutRes(R.layout.pickerview_custom_options, new CustomListener() {
                    @Override
                    public void customLayout(View v) {
                       // do somthing
                    }
                }).build();

In addition, The sample project can also be referred to .The link address:

351st lines , initCustomOptionPicker()

In the custom layout, the view of id: optionspicker or timepicker, and its child view can not modify their id, otherwise the NullPointerException will be reported.

Very good. I used the following code:

` public void showDatePicker(Calendar initialDate) { int year; if (initialDate == null) { initialDate = Calendar.getInstance(); year = (initialDate.get(Calendar.YEAR)) - 32; int month = 0;// January int day = 1; initialDate.set(year, month, day); }

    Calendar startDate = Calendar.getInstance();
    year = (startDate.get(Calendar.YEAR)) - 80;
    startDate.set(Calendar.YEAR, year);

    Calendar endDate = Calendar.getInstance();
    year = (endDate.get(Calendar.YEAR)) - 18;
    endDate.set(Calendar.YEAR, year);

    OnTimeSelectListener listener = (date, v) -> datePicked(Utils.toCalendar(date));

    TimePickerBuilder timePickerBuilder = new TimePickerBuilder(this, listener);
    timePickerBuilder.setType(new boolean[]{true, true, true, false, false, false});
    timePickerBuilder.setCancelText("Cancel");
    timePickerBuilder.setSubmitText("Ok");
    timePickerBuilder.setOutSideCancelable(false);
    timePickerBuilder.isCyclic(false);
    timePickerBuilder.setSubmitColor(getResources().getColor(R.color.colorAccent));
    timePickerBuilder.setCancelColor(getResources().getColor(R.color.colorAccent));
    timePickerBuilder.setTitleBgColor(Color.WHITE);
    timePickerBuilder.setBgColor(Color.WHITE);
    timePickerBuilder.setDividerColor(getResources().getColor(R.color.colorAccent));
    timePickerBuilder.setDate(initialDate);
    timePickerBuilder.setRangDate(startDate, endDate);
    timePickerBuilder.setLabel(" Year", " Month", " Day", "", "", "");
    timePickerBuilder.isCenterLabel(false);
    timePickerBuilder.isDialog(true);
    // text offset: Month, Day, Year affected by (2nd param, 1st param, 3rd param)
    timePickerBuilder.setTextXOffset(0, 10, -10, 0, 0, 0);
    timePickerBuilder.setLayoutRes(R.layout.datepicker, new CustomListener() {

        @Override
        public void customLayout(View v) {
            final Button btnSubmit = v.findViewById(R.id.btnSubmit);
            final Button btnCancel = v.findViewById(R.id.btnCancel);
            btnSubmit.setOnClickListener(v1 -> {
                pvTime.returnData();
                pvTime.dismiss();
            });
            btnCancel.setOnClickListener(v12 -> pvTime.dismiss());
        }
    });
    pvTime = timePickerBuilder.build();
    pvTime.show();
}`

and this xml for custom layout:
