Tabs in TabLayout not filled to parent in HDpi devices.

[vimosanan93]

Description: I have a tab in my application at bottom. I am using com.google.android.material.tabs.Tablayout for it. The issues I'm facing is the two tabs getting centred with wrap content. I searched at max, most of the developers suggested set the

TabMaxWidth to 0dp, TabMode to Fixed and TabGravity to Fill.

I tried with this solution. But nothing is working for me. I'm dealing with this minor issues for more than a day.

Expected behavior: Tabs should be filled with the match parent width.

Source code:

` <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical">

    <com.google.android.material.appbar.AppBarLayout
        android:id="@+id/app_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <androidx.appcompat.widget.Toolbar
            android:id="@+id/tool_bar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@android:color/white"
            app:popupTheme="@style/AppTheme.PopupOverlay">

            <include

        android:layout_width="match_parent"

Hello, has the same problem with TabLayout.

<androidx.coordinatorlayout.widget.CoordinatorLayout

    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.google.android.material.appbar.AppBarLayout
        android:id="@+id/appBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

            android:layout_height="wrap_content"
            app:layout_scrollFlags="scroll|enterAlways"
            app:navigationIcon="@drawable/ic_back_blue"
            app:title="Screen"/>

        <com.google.android.material.tabs.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabBackground="@drawable/selector_tab_indicator"
            app:tabIndicatorColor="@color/colorBlue"
            app:tabIndicatorHeight="2dp"
            app:tabSelectedTextColor="@color/colorBlue"
            app:tabMode="auto"
            app:tabTextAppearance="@style/AppTheme.TabLayout.TabTextAppearance"
            app:tabTextColor="@color/colorTypographyGrey" />
    </com.google.android.material.appbar.AppBarLayout>

    <androidx.viewpager.widget.ViewPager
        android:id="@+id/viewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>

Tried app:tabMode="scrollable", app:tabMode="scrollable" and app:tabGravity="fill"

Can you provide screenshots?

I'll close the issue due to no further info available. Feel free to reopen it if it's still reproducible.
