CheckBox not centered in TableRow

I'm struggling with aligning checkboxes in a table row in a layout described below. Where do I go wrong?

You can see in the picture that checkboxes are aligned to the left, and I want them in the center.

I tried all the features in layout-gravity, also tried to put the checkbox inside of another layout, but nothing helped.

The xml looks like this:

<!--  TABLE  -->
<TableLayout
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginLeft="@dimen/activity_horizontal_margin"
    android:layout_marginRight="@dimen/activity_horizontal_margin"
    android:layout_marginTop="@dimen/activity_top_margin"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <!--  HEADER  -->
    <TableRow android:background="@drawable/table_border_header">

        <TextView
            android:layout_width="0dp"
            android:layout_weight="1"
            android:background="@drawable/table_border_header"
            android:padding="4dp"
            android:text="HEADER 1"
            android:textAlignment="textStart"
            android:textAppearance="@android:style/TextAppearance.DeviceDefault.Medium"
            android:textStyle="bold" />

        <TextView
            android:layout_width="0dp"
            android:layout_weight="1"
            android:background="@drawable/table_border_header"
            android:padding="4dp"
            android:text="HEADER 2"
            android:textAlignment="center"
            android:textAppearance="@android:style/TextAppearance.DeviceDefault.Medium"
            android:textStyle="bold" />

        <TextView
            android:layout_width="0dp"
            android:layout_weight="1"
            android:background="@drawable/table_border_header"
            android:padding="4dp"
            android:text="HEADER 3"
            android:textAlignment="center"
            android:textAppearance="@android:style/TextAppearance.DeviceDefault.Medium"
            android:textStyle="bold" />

    </TableRow>

    <!-- SECOND ROW -->
    <TableRow android:background="@drawable/table_border">

        <TextView
            android:layout_width="0dp"
            android:layout_weight="1"
            android:background="@drawable/table_border"
            android:padding="4dp"
            android:text="SEED 1"
            android:textAlignment="textStart"
            android:textAppearance="@android:style/TextAppearance.DeviceDefault.Medium" />

        <CheckBox
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_weight="1"
            android:background="@drawable/table_border"
            android:textAppearance="@android:style/TextAppearance.DeviceDefault.Large" />

        <CheckBox
            android:layout_width="0dp"
            android:layout_gravity="center_horizontal"
            android:layout_weight="1"
            android:background="@drawable/table_border"
            android:textAppearance="@android:style/TextAppearance.DeviceDefault.Large" />

    </TableRow>
</TableLayout>
