我的项目使用的是 Constraintlayout 1.1.3，我刚刚将其版本更新为 2.0.4。

整个布局的一部分有点混乱。所以我检查了我的代码，我意识到我使用 layout_ConstraintLeft 或 right。

所以我添加了ConstraintLayout属性的“开始”和“结束”。但它仍然无法正常工作。

他们互相粘着。

此约束布局由平面层次结构组成。这个布局的另一部分仍然有效。

为什么它不起作用？

我该如何解决？

这就是我要的。 在此处输入图像描述

但它最终就像 tihs 一样。他们互相粘着。当我升级 ConstraintLayout 版本时。 在此处输入图像描述

这是我的 xml 代码。

我不清楚为什么您的布局不起作用或为什么在升级ConstraintLayout时它停止工作。我建议您将布局分解为其基本组件并重新构建为完整布局。

考虑到您发布的图像，以下是我将如何使用ConstraintLayout 链来解决此问题：

<androidx.constraintlayout.widget.ConstraintLayout 
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginEnd="16dp"
        android:src="@drawable/ic_launcher_foreground"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintDimensionRatio="1:1"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHeight_percent="0.15"
        app:layout_constraintTop_toTopOf="parent" />

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="16dp"
        android:src="@drawable/ic_launcher_foreground"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintDimensionRatio="1:1"
        app:layout_constraintHeight_percent="0.15"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginEnd="16dp"
        android:text="TextView"
        android:textAppearance="@style/TextAppearance.AppCompat.Display1"
        app:layout_constraintEnd_toStartOf="@+id/textView2"
        app:layout_constraintHorizontal_chainStyle="packed"
        app:layout_constraintStart_toEndOf="@+id/imageView"
        tools:layout_editor_absoluteY="172dp" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView"
        android:textAppearance="@style/TextAppearance.AppCompat.Display1"
        app:layout_constraintEnd_toStartOf="@+id/imageView2"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintStart_toEndOf="@+id/textView"
        tools:layout_editor_absoluteY="172dp" />
</androidx.constraintlayout.widget.ConstraintLayout>

此 XML 生成以下图像：

除此之外，请检查您拥有的所有约束是否都是您想要的，并且您了解它们在做什么。从基本布局开始，一次添加一个组件或一小组组件将是解决问题的合理方法。
