when using MAterialToolbar, how to set it's style in themes?

<item name="toolbarStyle">@style/Widget.Toolbar</item>

and then

<style name="Widget.Toolbar" parent="Widget.MaterialComponents.Toolbar">>

does nothing. does any1 have a clue ?

I don’t think you need any parents, just make sure you wrap it in the

AppBar

View XML:

<com.google.android.material.appbar.MaterialToolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        style="@style/Toolbar"
        />

Styles:

<style name="Toolbar">
...
</style>

this new theming is weird and confusing, but i found the problem. It works as expected. i was setting textColor in the style, but it must be inside another textAppearance style

Yep I agree with you, we use various components and finding right parent can be a bit tricky, you need to dig through components source code…

you can also use layout inspector, click on the widget and check theme/style inheritance. works great

Oh ye, thanks for the tip! 😄
