ConstraintLayout의 wrap에서conntent의 matchconstraint

ConstraintLayout의 wrap에서conntent의 match어떻게 해야 할지 어려워서 적어놨어요.
ConstraintLayout 1.1.2에 대한 쓰기 방법입니다.

wrap_conntent의 matchconstraint 모드 필요

이게 필요한 건 화면이Dialog Fragment ※ Constraint Layout에는 Scroll View가 있고 그 중에는 거대한 View 도안이 있습니다.
보통 match ScrollViewconstraint를 통해 해결하고 싶습니다. 화면이 대화상자인 상황에서match켜면 표시되지 않습니다.
※ 이번 인플랫, setView는 앱CompoatDialogFragment의 온크레이트Dialog에서 진행됐습니다.

Android Studio의 Preview는 정상적이지만 실제로 시작하면 제목만 남습니다.

해결책

ScrollView의 wrap콘텐츠를 지정하는 동시에layout진짜

<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"
    tools:context=".BlankFragment">

    <TextView
        android:id="@+id/textView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        android:layout_marginEnd="16dp"
        android:text="タイトル"
        android:textAppearance="@style/TextAppearance.AppCompat.Headline"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <ScrollView
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        android:layout_marginEnd="16dp"
        android:layout_marginBottom="16dp"
        app:layout_constrainedHeight="true"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/textView">

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

            <TextView
                android:id="@+id/textView1"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n Hello World!\n"
                app:layout_constraintLeft_toLeftOf="parent"
                app:layout_constraintRight_toRightOf="parent"
                app:layout_constraintTop_toTopOf="parent" />
        </android.support.constraint.ConstraintLayout>
    </ScrollView>

</android.support.constraint.ConstraintLayout>

예상대로 보이다.

옛 서법

이전에는 match ScrollView한쪽은constraint,한쪽은layoutconstraintHeight_default로 wrap을 지정하는 방법입니다.
이것은 deprecated입니다.

가로로 적용하기

가로 방향에 적용될 때 Height를 width로 바꿔 주십시오.
