layout_constraintHorizontal_weight = 1 在 ConstraintLayout 不工作

Question

TextInputLayout 中的 TextInputEditText 使用 wight 属性等于 ConstraintLayout 中的宽度。使用 layout_constraintHorizontal_weight = 1 不是 work.how 使用权重属性为 Textinputlayout 提供相同的宽度。这是给出的结果。

我想要以下结果：

xml 代码是：

<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

我对您的代码进行了一些修改以达到此目的。技巧是将第一个 firstName1 的结尾限制在 lastName1 的开头，并对 lastName1 执行相反的操作，并在边界处分配它们之间的边距。

        android:layout_marginStart="4dp"

        android:layout_marginEnd="8dp"
        app:boxBackgroundMode="outline"
