Question

I am making a number picker dialog having 2 number pickers, years and months. I want to show some default value in these 2 number picker, apart from 0, 0

Code::

    final NumberPicker numberPickerYear = (NumberPicker) expDialog.findViewById(R.id.numberPickerYears);
    final NumberPicker numberPickerMonth = (NumberPicker) expDialog.findViewById(R.id.numberPickerMonths);

    numberPickerYear.setMaxValue(35);
    numberPickerYear.setMinValue(0);
    numberPickerYear.setWrapSelectorWheel(true);

    numberPickerMonth.setMaxValue(11);
    numberPickerMonth.setMinValue(0);
    numberPickerMonth.setWrapSelectorWheel(true);

Answer 1

By default maxValue and minValue in NumberPicker is 0. So you need to set maxValue and minValue before using setValue.

numberPickerMonth.setValue(defaultQuanity);

Answer 2

READ Carefully:

void setValue (int value) Set the current value for the number picker.

1. If the argument is less than the getMinValue() and getWrapSelectorWheel() is false the current value is set to the getMinValue() value.
2. If the argument is less than the getMinValue() and getWrapSelectorWheel() is true the current value is set to the getMaxValue() value.
3. If the argument is less than the getMaxValue() and getWrapSelectorWheel() is false the current value is set to the getMaxValue() value.
4. If the argument is less than the getMaxValue() and getWrapSelectorWheel() is true the current value is set to the getMinValue() value.

    final NumberPicker numberPickerYear = (NumberPicker) expDialog.findViewById(R.id.numberPickerYears);
    final NumberPicker numberPickerMonth = (NumberPicker) expDialog.findViewById(R.id.numberPickerMonths);

    numberPickerYear.setMaxValue(35);
    numberPickerYear.setMinValue(0);
    numberPickerYear.setWrapSelectorWheel(true);
    numberPickerYear.setValue(17);// here to set default value of 

    numberPickerMonth.setMaxValue(11);
    numberPickerMonth.setMinValue(0);
    numberPickerMonth.setWrapSelectorWheel(true);
    numberPickerMonth.setValue(5);// here to set default value of numberPickerMonth
