textview和edittext之间的android约束布局对齐

Question

我需要在约束布局内的同一行中放置TextView 和EditText 并保持它们相互对齐！下面的代码生成如下图：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/serverIpAddr"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="192.168.1.11"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <EditText
        android:id="@+id/serverPort"
        style="@style/Widget.AppCompat.EditText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="0dp"
        android:layout_marginLeft="0dp"
        android:layout_marginTop="0dp"
        android:ems="10"
        android:inputType="number"
        android:text="8080"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"
        app:layout_constraintStart_toEndOf="@+id/serverIpAddr"
        app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

现在看起来很难看，TextView 和 EditText 日志水平对齐正确，TextView 略高于 EditText

Answer 1

您可以使用app:layout_constraintBaseline_toBaselineOf属性使两者的文本水平对齐

<TextView
    android:id="@+id/serverIpAddr"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="192.168.1.11"
    app:layout_constraintBaseline_toBaselineOf="@id/serverPort"
    android:textAppearance="@style/TextAppearance.AppCompat.Body1"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />
