如何在 ConstraintLayout 中以固定边距和动态宽度均匀放置视图？

Question

我想这样设置 ConstraintLayout:

我需要有固定的左右约束，大小尺寸比为 1:1 和灵活的宽度，它会调整到屏幕的实际宽度。我设置如下：

左右约束均为8dp
这些视图的大小设置为 "Any size"
layout_constraintDimensionRatio = "1:1"

我所拥有的是所有视图都设置为点，除了设置了左右约束的视图（其他视图只有左约束）。那一个应用了1:1比率的规则。

我应该怎么做才能修复此布局？

这是我尝试添加链的 xml:

<?xml version="1.0" encoding="utf-8"?>

        android:layout_marginRight="8dp"
        app:layout_constraintDimensionRatio="1:1" />

    <TextView
        android:id="@+id/textView5"
        android:text="5"
        android:layout_width="0dp"

        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintLeft_toRightOf="@+id/textView4"
        style="@style/TextViewCustom"
        app:layout_constraintDimensionRatio="1:1" />

</android.support.constraint.ConstraintLayout>

这是结果：

很接近，但还不够好。

您可以创建 chains 以确保相同的分布（例如每行一个链）——这样每个小部件将具有相同的尺寸。你描述的其余部分应该是正确的。

编辑：这是一些XML。诀窍是只在第一个元素上设置边距。
