Getting elevation bewteen Toolbar and Tablayout

Question

I am trying to create a layout which includes toolbar and tablayout inside appbarlayout. It works fine but shows a line between toolbar and appbarlayout. I am setting toolbar background color dynamically like:

toolbar.setBackgroundColor(Color.parseColor("myColor")); tabLayout.setBackgroundColor(Color.parseColor("myColor");

I have tried setting app:elevation="0dp" on Appbar and Toolbar but it doesn't work.

            android:fitsSystemWindows="true"
            android:theme="@style/AppTheme.AppBarOverlay">

            <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"

                app:tabGravity="fill"
                app:tabMode="scrollable" />

MyTabsStyle.xml:

    <item name="tabIndicatorHeight">2.5dp</item>
    <item name="android:elevation">2dp</item>
    <item name="tabIconTint">@color/colorWhite</item>
    <item name="tabSelectedTextColor">@color/colorWhite</item>
    <item name="tabTextColor">@color/white_trans</item>
</style>

Styles.xml:

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.MaterialComponents.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.MaterialComponents.Light" />

Try this

set elevation to 0dp in your MyTabsStyle.xml

MyTabsStyle.xml:

 <style name="MyTabStyle" parent="Widget.Design.TabLayout">
<item name="tabIndicatorColor">@color/colorWhite</item>
<item name="tabIndicatorHeight">2.5dp</item>
<item name="android:elevation">0dp</item>
<item name="tabIconTint">@color/colorWhite</item>
<item name="tabSelectedTextColor">@color/colorWhite</item>
<item name="tabTextColor">@color/white_trans</item></style>
