无法在文本更改时调整项目组并尊重边距

Question

我正在使用以下布局：

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

    xmlns:app="http://schemas.android.com/apk/res-auto"

        app:constraint_referenced_ids="right_txt1,right_txt2,right_txt3"/>


    <TextView

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        />

    <View
        android:id="@+id/view2"
        android:layout_width="120dp"
        android:layout_height="10dp"
        android:background="@color/green"
        app:layout_constraintTop_toTopOf="@id/right_txt2"
        app:layout_constraintBottom_toBottomOf="@id/right_txt2"
        app:layout_constraintEnd_toStartOf="@id/barrier"
        />

    <View
        android:id="@+id/view3"
        android:layout_width="120dp"
        android:layout_height="10dp"
        android:background="@color/green"
        app:layout_constraintTop_toTopOf="@id/right_txt3"
        app:layout_constraintBottom_toBottomOf="@id/right_txt3"
        app:layout_constraintEnd_toStartOf="@id/barrier"
        />

    <TextView
        android:id="@+id/left_txt1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="start"
        app:layout_constrainedWidth="true"
        app:layout_constraintTop_toTopOf="@id/view1"
        app:layout_constraintBottom_toBottomOf="@id/view1"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toStartOf="@id/view1"
        app:layout_constraintHorizontal_bias="0"
        android:text="FooBar"
        />

    <androidx.constraintlayout.widget.Constraints
        android:id="@+id/c1"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        app:layout_constraintTop_toBottomOf="@id/left_txt1"
        app:layout_constraintStart_toStartOf="parent"
        />

    <TextView
        android:id="@+id/left_txt2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constrainedWidth="true"
        app:layout_constraintTop_toTopOf="@id/view2"
        app:layout_constraintHorizontal_bias="0"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@id/c1"
        app:layout_constraintBottom_toBottomOf="@id/view2"
        app:layout_constraintEnd_toStartOf="@id/view2"
        android:text="FooBarBaz"
        />

    <androidx.constraintlayout.widget.Constraints
        android:id="@+id/c2"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        app:layout_constraintTop_toBottomOf="@id/left_txt2"
        app:layout_constraintStart_toStartOf="parent"
        />

    <TextView
        android:id="@+id/left_txt3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        app:layout_constraintTop_toTopOf="@id/view3"
        app:layout_constraintHorizontal_bias="0"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@id/left_txt2"
        app:layout_constraintBottom_toBottomOf="@id/view3"
        app:layout_constraintEnd_toStartOf="@id/view3"
        android:text="FooBar"
        />

</androidx.constraintlayout.widget.ConstraintLayout>

结果是：

对于这个例子来说没问题，但我想要的是随着文本的增长，各个项目作为一个整体进行调整而不会失去对齐。无法正常工作的示例：

而且边距不起作用
例如。添加 android:layout_marginBottom="18dp" 到 left_txt1 没有效果或添加 </code>android:layout_marginBottom="18dp"<code>to theleft_txt2` 效果如下

我希望随着文本的增长，项目 bellow/above 将 space 作为一组

我在这里搞砸了什么？

您应该按照 TextView 的高度对齐栏 View，反之亦然。

Answer 2

为了使左侧 TextViews 不相互重叠，您需要在它们之间创建垂直约束。然后，每个进度条和右侧 TextView 应根据相应左侧 TextView 的高度进行约束，而不是相反，如其他答案所述。
