    <color name="colorAccent">#000000</color> // changing icons color 
    <color name="textColorPrimary">#000000</color> // i m not sure if this is correct but i think it is for toolbar text ( i could be wrong )

Answer 1

您可以使用：

 <com.google.android.material.appbar.AppBarLayout
    ...>

        <com.google.android.material.appbar.CollapsingToolbarLayout
            android:fitsSystemWindows="true"
            app:contentScrim="@color/..."
            android:theme="@style/CollapsingToolbarLayout_Overlay"
            >

    

与：

<style name="CollapsingToolbarLayout_Overlay">
    <!-- Title text color -->
    <item name="android:textColorPrimary">@color/....</item>
    <!-- Toolbar up color -->
    <item name="colorControlNormal">@color/...</item>
</style>
