android - 在 ConstraintLayout 中使用 FrameLayout

Question

我有以下ConstraintLayout:

<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:id="@+id/detail"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/contact_selector"
    android:minHeight="64dp">

    <FrameLayout
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="@+id/guideline"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="@+id/guideline">

        <TextView
            android:id="@+id/image_text"
            android:layout_width="48dp"
            android:layout_height="48dp"
            android:layout_marginLeft="16dp"
            android:layout_marginStart="16dp"
            android:background="@drawable/contact_circle"
            android:gravity="center"
            tools:text="A.R" />

    </FrameLayout>

    <TextView
        android:id="@+id/contact_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ellipsize="end"
        android:maxLines="1"
        android:paddingLeft="16dp"
        android:paddingStart="16dp"
        android:textSize="17sp"
        app:layout_constrainedWidth="true"
        app:layout_constraintBottom_toTopOf="@+id/guideline"
        app:layout_constraintHorizontal_bias="0"
        app:layout_constraintStart_toEndOf="@+id/image"
        tools:layout_constraintEnd_toStartOf="@id/phone_type"
        tools:text="Ali Rezaei" />

    <TextView
        android:id="@+id/phone_number"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="16dp"
        android:paddingStart="16dp"
        android:textSize="13sp"
        app:layout_constraintStart_toStartOf="@+id/contact_name"
        app:layout_constraintTop_toTopOf="@+id/guideline"
        tools:text="+989121895634" />

    <android.support.constraint.Guideline
        android:id="@+id/guideline"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.5" />

    <View
        android:id="@+id/line"
        style="@style/LineStyle"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toEndOf="@+id/image" />

</android.support.constraint.ConstraintLayout>

如您所见，布局中有一个名为 id:image 的 Framelayout。原因是在 id:image_text

中使用了边距

android:layout_marginLeft="16dp"
android:layout_marginStart="16dp"

ConstraintLayout 中是否有任何解决方案可以避免在我的情况下使用 FrameLayout？

Answer 1

希望这正是您要查找的内容。我对填充做了一些更改(改为添加边距)并删除了 FrameLayout:

<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:id="@+id/detail"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="64dp">

    <TextView
        android:id="@+id/image_text"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:layout_marginStart="16dp"
        android:layout_marginLeft="16dp"
        android:background="@drawable/img_profile"
        android:gravity="center"
        app:layout_constraintBottom_toBottomOf="@+id/guideline"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintTop_toTopOf="@+id/guideline"
        tools:text="A.R" />

    <TextView
        android:id="@+id/contact_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="15dp"
        android:ellipsize="end"
        android:maxLines="1"
        android:textSize="17sp"
        app:layout_constrainedWidth="true"
        app:layout_constraintBottom_toTopOf="@+id/guideline"
        app:layout_constraintHorizontal_bias="0"
        app:layout_constraintStart_toEndOf="@+id/image_text"
        tools:layout_constraintEnd_toStartOf="@id/phone_type"
        tools:text="Ali Rezaei" />

    <TextView
        android:id="@+id/phone_number"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="13sp"
        app:layout_constraintStart_toStartOf="@+id/contact_name"
        app:layout_constraintTop_toTopOf="@+id/guideline"
        tools:text="+98912000000" />

    <android.support.constraint.Guideline
        android:id="@+id/guideline"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.5" />

    <View
        android:id="@+id/line"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toEndOf="@+id/image_text" />

</androidx.constraintlayout.widget.ConstraintLayout>

输出:
