如何在ConstraintLayout中使用固定边距和动态宽度均匀地放置视图？

Question

我想像这样设置ConstraintLayout:

我需要固定左右约束,尺寸尺寸比为1:1,宽度将是灵活的,它将调整到屏幕的实际宽度.我设置如下:

1. 左右约束是8dp
2. 这些视图的大小设置为"任意大小"
3. layout_constraintDimensionRatio ="1:1"

我所拥有的是所有视图都被设置为点,除了设置左右约束(其他只有左约束)的视图.那个人应用了1:1的比例规则.

我该怎么做才能修复这个布局？

这是我尝试添加链的xml:

<?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_marginRight="8dp"
        app:layout_constraintDimensionRatio="1:1" />

    <TextView
        android:id="@+id/textView2"
        android:text="2"
        android:layout_width="0dp"
        android:layout_height="0dp"

    <TextView

        android:layout_width="0dp"

        app:layout_constraintHorizontal_weight="1"
        app:layout_constraintBaseline_toBaselineOf="@+id/textView"
        style="@style/TextViewCustom"
        app:layout_constraintRight_toLeftOf="@+id/textView4"
        app:layout_constraintLeft_toRightOf="@+id/textView2"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        app:layout_constraintDimensionRatio="1:1" />

    <TextView
        android:id="@+id/textView4"
        android:text="4"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintHorizontal_weight="1"
        app:layout_constraintBaseline_toBaselineOf="@+id/textView"
        style="@style/TextViewCustom"
        app:layout_constraintRight_toLeftOf="@+id/textView5"
        app:layout_constraintLeft_toRightOf="@+id/textView3"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        app:layout_constraintDimensionRatio="1:1" />

    <TextView
        android:id="@+id/textView5"
        android:text="5"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintHorizontal_weight="1"
        app:layout_constraintBaseline_toBaselineOf="@+id/textView"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintLeft_toRightOf="@+id/textView4"
        style="@style/TextViewCustom"
        app:layout_constraintDimensionRatio="1:1" />

</android.support.constraint.ConstraintLayout>

这就是结果:

非常接近,但还不够好.

您可以创建链以确保相同的分布(例如,每行一个链) - 这样每个小部件将具有相同的维度.你描述的其余内容应该是正确的.

编辑:这是一些XML.诀窍是仅在第一个元素上设置边距.
