如何在我的号码选择器索引中设置当前月和年？

Question

How to can I set the current month and year in my NumberPicker index ? I have two NumberPicker instances - the first is for the and second is for the year. Both are set as string arrays, but how do I set current position as the current month?

Here is my current code:

final String wheelMenu2[] = {
    "Jan",
    "Feb",
    "Mar",
    "Apr",
    "May",
    "Jun",
    "Jul",
    "Aug",
    "Sep",
    "Oct",
    "Nov",
    "Dec"
};

NumberPicker numberPicker2 = (NumberPicker) findViewById(R.id.numberpicker2);
numberPicker2.setMinValue(0);
numberPicker2.setMaxValue(wheelMenu2.length-1);
numberPicker2.setWrapSelectorWheel(true); 
numberPicker2.setDisplayedValues(wheelMenu2);

int posmonthwheel2 =numberPicker2.getValue();
s4 = wheelMenu2[posmonthwheel2];

    SimpleDateFormat dayFormat = new SimpleDateFormat("MMM", Locale.US);

    Calendar calendar = Calendar.getInstance();
    String month = dayFormat.format(calendar.getTime());

month will give have the value of the current month ie, Jan, Feb, Mar etc. Use this to compare with your array and set it to the view

and for setting in your number formatter use the below method,

numberPicker.setValue(// int position value of the result);
