Android 安卓4.3。滚动条和右边框之间的间隙

这里是我的xml布局：带ViewPager的表格布局：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.TabLayout
        android:id="@+id/tabLayout"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        android:background="@android:color/white"
        android:minHeight="@dimen/standard_min_height_container"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/searchView"
        app:tabGravity="fill"
        app:tabIndicatorHeight="0dp"
        app:tabMode="fixed"
        app:tabSelectedTextColor="@color/colorPrimaryDark"
        app:tabTextAppearance="@android:style/TextAppearance.Widget.TabWidget" />

    <ViewPager
        android:id="@+id/customViewPager"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="@color/common_color_bg"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="@+id/tabLayout"
        app:layout_constraintRight_toRightOf="@+id/tabLayout"
        app:layout_constraintTop_toBottomOf="@+id/tabLayout" />

</android.support.constraint.ConstraintLayout>

这是安卓4.3的结果


为什么在Androdi4.3上。右边框和滚动条之间有间隙吗？
我需要显示滚动条以正确对齐。与Android 5.0+上一样，您应该将scrollbarStyle更改为所需的样式

android:scrollbarStyle:

 insideInset    //Inside the padding and inset.
 insideOverlay //Inside the padding and overlaid.
 outsideInset //Edge of the view and inset.
 outsideOverlay //Edge of the view and overlaid.

看看这个
