Solution

  • Currently (1.3.0) the only way to define the textAppearance and the font used by the Tooltip in the Slider is with a style:

    <style name="App.Slider" parent="@style/Widget.MaterialComponents.Slider">
    <item name="labelStyle">@style/App.Tooltip</item>
</style>

<style name="App.Tooltip" parent="Widget.MaterialComponents.Tooltip">
    <item name="android:textAppearance">@style/TextAppearance.MaterialComponents.Tooltip</item>
</style>

    If you would like to use a reflection (I discourage it) you have to access to List<TooltipDrawable> labels defined in the BaseSlider class.
    Then you can use the methods setTextAppearance or setTextAppearanceResource defined in the TooltipDrawable class
