MaterialNumberPicker

Native NumberPicker	MaterialNumberPicker (default)	MaterialNumberPicker (custom)

Usage

Both XML and programmatic instanciations are supported :

<com.core.youxin.MaterialNumberPicker
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:mnpDefaultValue="10"
        app:mnpEditable="false"
        app:mnpFontname="Hand.ttf"
        app:mnpMaxValue="50"
        app:mnpMinValue="1"
        app:mnpSeparatorColor="@color/colorAccent"
        app:mnpTextColor="@color/colorPrimary"
        app:mnpTextSize="16sp"
        app:mnpTextStyle="bold"
        app:mnpWrapped="false" />

val numberPicker = MaterialNumberPicker(
        context = this,
        separatorColor = ContextCompat.getColor(this, R.color.colorAccent),
        textColor = ContextCompat.getColor(this, R.color.colorPrimary),
        textSize = resources.getDimensionPixelSize(R.dimen.numberpicker_textsize),
        textStyle = Typeface.BOLD_ITALIC,
        defaultValue = 10,
        minValue = 1,
        maxValue = 50,
        editable = false,
        wrapped = false,
        fontName = "Hand.ttf",
        formatter = NumberPicker.Formatter {
            return@Formatter "Value $it"
        }
)

Once you have your number picker, you can present it by itself, or within an alert dialog :

AlertDialog.Builder(this)
        .setTitle(title)
        .setView(numberPicker)
        .setNegativeButton(getString(android.R.string.cancel), null)
        .setPositiveButton(getString(android.R.string.ok), { _, _ ->
            Toast.makeText(this, getString(R.string.picker_value, numberPicker.value), Toast.LENGTH_LONG).show()
        })
        .show()
