android - ConstraintLayout 中心布局

Question

我有以下物品

我想包含在另一个这样的布局中

问题是底部的两个图像没有居中

这是我的代码，我需要知道如何使它们居中

 <?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout

            android:layout_marginEnd="4dp"/>

</androidx.constraintlayout.widget.ConstraintLayout>

你需要使用Chains

• 链在单个轴（水平或垂直）上提供类似组的行为。另一个轴可以独立约束。

欲了解更多信息，请检查

• Chains in ConstraintLayout
• ConstraintLayout Chains

示例代码

<androidx.constraintlayout.widget.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="wrap_content"
    android:background="@android:color/transparent">

    <include
        android:id="@+id/inAppCheck"
        layout="@layout/item_square_bool"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        app:layout_constraintEnd_toStartOf="@+id/voipCheck"
        app:layout_constraintStart_toStartOf="parent" />

    <include
        android:id="@+id/voipCheck"

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginEnd="8dp"
        app:layout_constraintEnd_toStartOf="@+id/anonymousCheck"
        app:layout_constraintStart_toEndOf="@+id/inAppCheck" />

    <include
        android:id="@+id/anonymousCheck"
        layout="@layout/item_square_bool"
        android:layout_width="wrap_content"

        android:layout_marginEnd="8dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toEndOf="@+id/voipCheck" />

    <include
        android:id="@+id/autoPostCheck"
