This is an easy to use custom preference, which opens a dialog with a number picker. The value gets automatically saved and you can set the default-, min- and maxValue conveniently in the XML.

<com.vanniktech.vntnumberpickerpreference.VNTNumberPickerPreference
    android:defaultValue="@integer/font_size_default_value"
    android:key="preference_font_size"
    android:title="@string/font_size"
    app:vnt_maxValue="@integer/font_size_max_value"
    app:vnt_minValue="@integer/font_size_min_value"
    app:vnt_setWrapSelectorWheel="true"/>
