How to set 2 tab takes equal width in tablayout

Question

I am adding 2 tabs in the TabLayout, and following is my code.

<com.google.android.material.tabs.TabLayout
    android:id="@+id/tabLayout"
    style="@style/AppTabLayout"
    android:layout_width="match_parent"
    android:layout_height="30dp"
    android:layout_gravity="center"
    app:tabBackground="@drawable/tab_selector_statistics"
    android:background="@drawable/tab_statistics"
    app:tabContentStart="24dp"
    app:tabGravity="fill"
    app:tabMode="fixed"
    app:tabSelectedTextColor="@color/white"
    app:tabTextColor="@color/black"
    app:layout_constraintBottom_toBottomOf="@+id/view5"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="@+id/view5"
    android:layout_alignParentTop="true"
    android:layout_alignParentBottom="true" />

I am getting the following output.

But I want tabs to take the full width of the screen, as follows.

Following is my AppTabLayout style defined in styles.xml file.

<style name="AppTabLayout" parent="Widget.Design.TabLayout">
    <item name="tabIndicatorColor">@null</item>
    <item name="tabIndicatorHeight">1dp</item>
    <item name="tabPaddingStart">16dp</item>
    <item name="tabPaddingEnd">16dp</item>
    <item name="tabSelectedTextColor">@color/white</item>
</style>

Can you try with android:layout_width="0dp"? match_parent is not supported inside ConstraintLayout. – Chantry

@EugenPechanec : Tanks for the reply, I tried 0dp but still getting the same output. – Iman

@Kirmani88 answer below is correct, need to add just one line app:tabMaxWidth="0dp", if not, you should show whole layout – Jink

have you try this: https://mcmap.net/q/713185/-different-tab-width-for-tablayout – Regurgitation

Use style

<style name="MyTabLayout" parent="Widget.Design.TabLayout">
    <item name="tabGravity">fill</item>
    <item name="tabMaxWidth">0dp</item>
</style>

or

<android.support.design.widget.TabLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabMaxWidth="0dp"
            app:tabGravity="fill"
            app:tabMode="fixed" />

match_parent is not supported by ConstraintLayout. Set width to 0dp to let it match constraints.

android:layout_width="0dp"

From the official doc:

Important: MATCH_PARENT is not recommended for widgets contained in a ConstraintLayout. Similar behavior can be defined by using MATCH_CONSTRAINT with the corresponding left/right or top/bottom constraints being set to "parent".

You should be use stretchColumns in Table Layout

<TableLayout
        android:stretchColumns="*">
        <TableRow
            android:layout_width="0dp">
    <TableRow
            android:layout_width="0dp">
</TableLayout>

<android.support.design.widget.TabLayout
                android:id="@+id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:tabBackground="@color/colorPrimary"
                app:tabIndicatorColor="@android:color/white"
                app:tabTextColor="@android:color/white"
                app:tabMode="fixed"
                app:tabGravity="fill"/>

In my case, I succeeded in getting the accepted output with just this one line of code: app:tabMode="fixed".

Full code of my TabLayout:

<com.google.android.material.tabs.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="?actionBarSize"
            android:paddingBottom="2dp"
            app:tabMode="fixed"
            app:tabTextColor="?titleTextColor"
            android:background="?android:statusBarColor" />

        android:elevation="@dimen/dimen_10"
