Android ConstraintLayout ScrollView не прокручивается

/ 12 января 2020

У меня есть этот макет, но он не прокручивается.

Я хочу сделать изображение больше экрана устройства (он же 1440x3040 xxhdpi).

Поэтому я установил scrollVeiw android:layout_height="1453dp" , (это число взято с zeplin dashboard)

Если я установлю scrollVeiw в android:layout_height="match_parent", это сделает вид слишком коротким. посмотреть изображение дизайна

Вот мой xml код 

<ScrollView
    android:id="@+id/scrollView2"
    android:layout_width="match_parent"
    android:layout_height="1453dp"
    android:fillViewport="true"
    app:layout_constraintTop_toTopOf="parent"

Установите фиксированную высоту (1453dp) для ConstraintLayout и установите высоту ScrollView match_parent: 

<ScrollView
    android:id="@+id/scrollView2"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    app:layout_constraintTop_toTopOf="parent"
    >

    <androidx.constraintlayout.widget.ConstraintLayout
        android:id="@+id/layout1"
        android:layout_width="match_parent"
        android:layout_height="1453dp">

        ...

    </androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>

Попробуйте использовать NestedScrollView вместо scrollview 

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="700dp">

    </android.support.constraint.ConstraintLayout>
