android - 使用约束布局等距四张图像

Question

我想使用约束布局等距四张图像......我使用了指导方针，但它给了我很多图像之间的空间，并且右角图像超出了屏幕
我想要这样的东西-->

但是从下面的代码我得到了这个 -->

从另一个设备我尝试运行它没有给出预期的结果
以下是代码:--

不同的设备提供不同的输出但不需要一个(第一张图片)
需要帮助才能适合所有设备(小设备到大设备)

Answer 1

不确定您对问题的确切要求，但我可以看到您需要在设备上显示 4 个宽度和高度相等的正方形。
您不需要为垂直和水平使用指南，而是垂直分布它，您可以使用屏障来正确对齐它们。
查看下面的代码:

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

    <androidx.viewpager.widget.ViewPager
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_margin="4dp"
        app:layout_constraintBottom_toTopOf="@id/image_divider"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/vertical_divider"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:layout_constraintGuide_percent=".5" />

    <androidx.constraintlayout.widget.Barrier
        android:id="@+id/image_divider"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:barrierDirection="top"
        app:constraint_referenced_ids="view1, view2" />

    <androidx.constraintlayout.widget.Barrier
        android:id="@+id/horizontal_divider"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:barrierDirection="top"
        app:constraint_referenced_ids="view3, view4" />
    
    <View
        android:id="@+id/view1"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_margin="4dp"
        android:background="@android:color/holo_orange_dark"
        app:layout_constraintBottom_toTopOf="@id/horizontal_divider"
        app:layout_constraintDimensionRatio="1:1"
        app:layout_constraintEnd_toStartOf="@id/vertical_divider"
        app:layout_constraintStart_toStartOf="parent" />

    <View
        android:id="@+id/view2"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_margin="4dp"
        android:background="@android:color/holo_orange_light"
        app:layout_constraintBottom_toTopOf="@id/horizontal_divider"
        app:layout_constraintDimensionRatio="1:1"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toEndOf="@id/vertical_divider" />

    <View
        android:id="@+id/view3"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_margin="4dp"
        android:background="@android:color/holo_red_light"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintDimensionRatio="1:1"
        app:layout_constraintEnd_toStartOf="@id/vertical_divider"
        app:layout_constraintStart_toStartOf="parent" />

    <View
        android:id="@+id/view4"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_margin="4dp"
        android:background="@android:color/holo_red_dark"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintDimensionRatio="1:1"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toEndOf="@id/vertical_divider" />
</androidx.constraintlayout.widget.ConstraintLayout>

输出:

(这将在不同的屏幕尺寸上保持一致)

这里，垂直指南用于在水平方向上均匀分布 View ，而屏障用于在垂直方向对齐两个 View 。
尺寸比例用于使正方形与 0dp保持一致作为高度和宽度。
编辑: O.P. 寻求在底部用方形框排列整个 View 层次结构的解决方案，下面给出了完整的代码:
