#### Java

```java

NumberPicker numberPicker = (NumberPicker) findViewById(R.id.number_picker);

// Set divider color

numberPicker.setDividerColor(ContextCompat.getColor(this, R.color.colorPrimary));

numberPicker.setDividerColorResource(R.color.colorPrimary);

// Set formatter

numberPicker.setFormatter(getString(R.string.number_picker_formatter));

numberPicker.setFormatter(R.string.number_picker_formatter);

// Set selected text color

numberPicker.setSelectedTextColor(ContextCompat.getColor(this, R.color.colorPrimary));

numberPicker.setSelectedTextColorResource(R.color.colorPrimary);

// Set selected text size

numberPicker.setSelectedTextSize(getResources().getDimension(R.dimen.selected_text_size));

numberPicker.setSelectedTextSize(R.dimen.selected_text_size);

// Set selected typeface

numberPicker.setSelectedTypeface(Typeface.create(getString(R.string.roboto_light), Typeface.NORMAL));

numberPicker.setSelectedTypeface(getString(R.string.roboto_light), Typeface.NORMAL);

numberPicker.setSelectedTypeface(getString(R.string.roboto_light));

numberPicker.setSelectedTypeface(R.string.roboto_light, Typeface.NORMAL);

numberPicker.setSelectedTypeface(R.string.roboto_light);

// Set text color

numberPicker.setTextColor(ContextCompat.getColor(this, R.color.dark_grey));

numberPicker.setTextColorResource(R.color.dark_grey);

// Set text size

numberPicker.setTextSize(getResources().getDimension(R.dimen.text_size));

numberPicker.setTextSize(R.dimen.text_size);

// Set typeface

numberPicker.setTypeface(Typeface.create(getString(R.string.roboto_light), Typeface.NORMAL));

numberPicker.setTypeface(getString(R.string.roboto_light), Typeface.NORMAL);

numberPicker.setTypeface(getString(R.string.roboto_light));

numberPicker.setTypeface(R.string.roboto_light, Typeface.NORMAL);

numberPicker.setTypeface(R.string.roboto_light);

// Set value

numberPicker.setMaxValue(59);

numberPicker.setMinValue(0);

numberPicker.setValue(3);

// Using string values

// IMPORTANT! setMinValue to 1 and call setDisplayedValues after setMinValue and setMaxValue

String[] data = {"A", "B", "C", "D", "E", "F", "G", "H", "I"};

numberPicker.setMinValue(1);

numberPicker.setMaxValue(data.length);

numberPicker.setDisplayedValues(data);

numberPicker.setValue(7);

// Set fading edge enabled

numberPicker.setFadingEdgeEnabled(true);

// Set scroller enabled

numberPicker.setScrollerEnabled(true);

// Set wrap selector wheel

numberPicker.setWrapSelectorWheel(true);

// Set accessibility description enabled

numberPicker.setAccessibilityDescriptionEnabled(true);

        

// OnClickListener

numberPicker.setOnClickListener(new View.OnClickListener() {

    @Override

    public void onClick(View view) {

        Log.d(TAG, "Click on current value");

    }

});

// OnValueChangeListener

numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {

    @Override

    public void onValueChange(NumberPicker picker, int oldVal, int newVal) {

        Log.d(TAG, String.format(Locale.US, "oldVal: %d, newVal: %d", oldVal, newVal));

    }

});

// OnScrollListener

numberPicker.setOnScrollListener(new NumberPicker.OnScrollListener() {

    @Override

    public void onScrollStateChange(NumberPicker picker, int scrollState) {

        if (scrollState == SCROLL_STATE_IDLE) {

            Log.d(TAG, String.format(Locale.US, "newVal: %d", picker.getValue()));

        }

    }

});
