Remove AppCompat styles about material-about-library

[marcardar]

Thanks Daniel. I've been playing around with:

title: TextAppearance.MaterialComponents.Headline6
subtitle: TextAppearance.MaterialComponents.Subtitle2

but the title looks very big to me, even though Headline6 is supposed to be the smallest. What do you think?

As a workaround I add android:textSize="16sp" (for the title) to make it look nicer, but I'm wary of using non-standard metrics.

Also, should the text in title_item and action_item look the same? If so, should that part be extracted into its own layout xml and then "included" in the two different existing layouts.

I just realised that, anyway, we should be using ?attr/ rather than the style resources directly. And it looks better because we can use the proper text appearance attrs for lists (and no need to tweak the text size):

title: ?android:attr/textAppearanceListItem
subtitle: ?android:attr/textAppearanceListItemSecondary (and personally I prefer to add android:textColor="?android:attr/textColorSecondary")

card title: ?attr/textAppearanceHeadline6 (and I personally add android:textSize="14sp")

Yep, currently quite busy - will try and get round to this in the following week. Thanks :)

Reopening as I'm not sure why I closed this. Will make these changes or accept a PR for them :)
