将视图与另一个视图的左右位置对齐，约束布局？

Question

我需要在约束布局的帮助下创建视图，如下图所示

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>

根据上面的代码，视图彼此重叠。我希望textview左边有一个视图，右边有其他视图。

以下是具有以下结果的代码

<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"

    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>

如果您稍微调整代码，您将获得所需的结果。

<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" />
