Android 4.3。 scrollBar和右边框之间的差距

Question

这是我的xml布局：带有ViewPager的TabLayout：

<?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>

Androd 5.0 +上的结果

这是Android 4.3的结果

为什么选择Androdi 4.3。右边框和scrollBar之间有差距？ 我需要显示scrollBar才能正确对齐。就像在Android 5.0 +上一样

Answer 1

您应该将scrollbarStyle更改为您想要的那个。

机器人：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.
