Question

我需要借助约束布局将视图创建为下图

这是我的xml代码：

<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/White">

<View
    android:id="@+id/left"
    android:layout_width="match_parent"
    android:layout_height="5dp"
    android:layout_marginLeft="20dp"
    android:layout_marginTop="120dp"
    android:background="@android:color/holo_orange_dark"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintLeft_toRightOf="@+id/or"
    app:layout_constraintTop_toTopOf="parent" />

<TextView
    android:id="@+id/or"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="100dp"
    android:text="OR"
    android:textSize="40sp"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<View
    android:id="@+id/right"
    android:layout_width="match_parent"
    android:layout_height="5dp"
    android:layout_marginTop="120dp"
    android:layout_marginRight="10dp"
    android:background="@android:color/holo_red_dark"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toLeftOf="@+id/or"
    app:layout_constraintTop_toTopOf="parent" />

    </android.support.constraint.ConstraintLayout>

按照上面的代码，视图彼此重叠。我希望一个视图位于textview的左侧，而其他视图位于右侧。

您可以使用链条有关链式检查的更多详细信息：https://constraintlayout.com/basics/create_chains.html

<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">


    <View
        android:id="@+id/left"
        android:layout_width="0dp"
        android:layout_height="5dp"
        android:layout_marginTop="125dp"
        android:layout_marginEnd="@dimen/_5sdp"
        android:layout_marginStart="@dimen/_5sdp"
        app:layout_constraintHorizontal_weight="1"
        android:background="@android:color/holo_orange_dark"
        app:layout_constraintEnd_toStartOf="@+id/or"
        app:layout_constraintHorizontal_chainStyle="spread_inside"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
        android:id="@+id/or"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="100dp"
        android:text="OR"
        android:textSize="40sp"
        app:layout_constraintHorizontal_weight="1"
        app:layout_constraintEnd_toStartOf="@+id/right"
        app:layout_constraintStart_toEndOf="@+id/left"
        app:layout_constraintTop_toTopOf="parent" />

    <View
        android:id="@+id/right"
        android:layout_width="0dp"
        android:layout_height="5dp"
        android:layout_marginStart="@dimen/_5sdp"
        android:layout_marginEnd="@dimen/_5sdp"

        android:background="@android:color/holo_red_dark"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toEndOf="@+id/or"
        app:layout_constraintTop_toTopOf="@+id/left" />

</androidx.constraintlayout.widget.ConstraintLayout>

这是带有以下结果的代码

<android.support.constraint.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white">

<View
    android:id="@+id/left"
    android:layout_width="wrap_content"
    android:layout_height="5dp"
    android:layout_marginLeft="20dp"
    android:layout_marginTop="120dp"
    android:layout_marginEnd="10dp"
    android:background="@android:color/holo_orange_dark"
    app:layout_constraintRight_toLeftOf="@+id/or"
    app:layout_constraintTop_toTopOf="parent" />

<TextView
    android:id="@+id/or"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="100dp"
    android:text="OR"
    android:textSize="40sp"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<View
    android:id="@+id/right"
    android:layout_width="wrap_content"
    android:layout_height="5dp"
    android:layout_marginStart="10dp"
    android:layout_marginTop="120dp"
    android:layout_marginRight="10dp"
    android:background="@android:color/holo_red_dark"
    app:layout_constraintLeft_toRightOf="@+id/or"
    app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>

如果您像这样稍微调整代码，将获得所需的结果。

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <View
        android:id="@+id/left"
        android:layout_width="0dp"
        app:layout_constraintHorizontal_weight="1"
        android:layout_height="5dp"
        android:layout_marginStart="20dp"
        android:layout_marginTop="120dp"
        android:background="@android:color/holo_orange_dark"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toLeftOf="@id/or"
        app:layout_constraintTop_toTopOf="parent"
         />

    <TextView
        android:id="@+id/or"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="100dp"
        android:text="OR"
        android:textSize="40sp"
        app:layout_constraintLeft_toRightOf="@id/left"
        app:layout_constraintRight_toLeftOf="@id/right"
        app:layout_constraintTop_toTopOf="parent" />

    <View
        android:id="@+id/right"
        android:layout_width="0dp"
        app:layout_constraintHorizontal_weight="1"
        android:layout_height="5dp"
        android:layout_marginTop="120dp"
        android:layout_marginRight="10dp"
        android:background="@android:color/holo_red_dark"
        app:layout_constraintLeft_toRightOf="@id/or"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />


</android.support.constraint.ConstraintLayout>

将视图与另一个视图的左右位置对齐，约束布局？
