android - 如何适应嵌套 ScrollView 中的布局

Question

我在 NestedScrollView 中包含了一个 ConstraintLayout，但我遇到了问题。当布局包括它的高度不与父级匹配时。这意味着 ConstraintLayout 的底部到最后一个 subview 。

这是我的约束布局:

 <?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/background_card"
 android:layoutDirection="ltr">

<ss.com.bannerslider.views.BannerSlider
    android:id="@+id/image_banner_slider"
    android:layout_width="match_parent"
    android:layout_height="250dp"
    android:adjustViewBounds="true"
    android:scaleType="centerCrop"
    app:defaultIndicators="circle"
    app:interval="7000"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:loopSlides="true"
    tools:src="@drawable/horse_banner_1" />

<com.example.davod.a4nal.Custom.CustomFontTextView
    android:id="@+id/txt_welcome"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginEnd="16dp"
    android:layout_marginTop="16dp"

    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintStart_toEndOf="@+id/btn_request_horse"
    app:layout_constraintTop_toBottomOf="@+id/txt_welcome" />

<Button
    android:id="@+id/btn_request_horse"
    android:layout_width="150dp"
    android:layout_height="wrap_content"
    android:layout_marginEnd="8dp"
    android:layout_marginTop="96dp"
    android:background="@drawable/selector_button_login"
    android:text=" درخواست اسب"

    app:layout_constraintEnd_toStartOf="@+id/btn_sell_horse"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintHorizontal_chainStyle="packed"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/image_banner_slider" />

<Button
    android:id="@+id/btn_sell_horse_object"
    android:layout_width="150dp"
    android:layout_height="wrap_content"
    android:layout_marginStart="8dp"
    android:layout_marginTop="16dp"
    android:background="@drawable/selector_button_login"
    android:text="فروش تجهیزات"
    android:textSize="@dimen/standard_size_title"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintStart_toEndOf="@+id/btn_request_horse_object"
    app:layout_constraintTop_toBottomOf="@+id/btn_sell_horse" />

<Button
    android:id="@+id/btn_request_horse_object"
    android:layout_width="150dp"
    android:layout_height="wrap_content"
    android:layout_marginEnd="8dp"
    android:layout_marginTop="16dp"
    android:background="@drawable/selector_button_login"
    android:text="درخواست تجهیزات"
    android:textSize="@dimen/standard_size_title"
    app:layout_constraintEnd_toStartOf="@+id/btn_sell_horse_object"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintHorizontal_chainStyle="packed"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/btn_request_horse" />

<Button
    android:id="@+id/btn_gravitation_horse"
    android:layout_width="317dp"
    android:layout_height="wrap_content"
    android:layout_marginBottom="16dp"
    android:layout_marginTop="16dp"

    app:layout_constraintTop_toBottomOf="@+id/btn_sell_horse_object"
    app:layout_constraintVertical_bias="0.0" />


</android.support.constraint.ConstraintLayout>

这是我的主要布局:

<?xml version="1.0" encoding="utf-8"?>

    <android.support.v4.widget.NestedScrollView

    </android.support.v4.widget.NestedScrollView>


    <android.support.design.widget.FloatingActionButton
        android:id="@+id/float_action_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|left"
        android:layout_margin="12dp"
        app:fabSize="normal"
        app:srcCompat="@drawable/vc_add_black_24dp"
        tools:ignore="VectorDrawableCompat" />

 </android.support.design.widget.CoordinatorLayout>

 <android.support.design.widget.NavigationView
    android:id="@+id/navigation_view"
    android:layout_width="300dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:layoutDirection="rtl"
    app:headerLayout="@layout/navigation_header_layout"
    app:menu="@menu/navigation_menu" />


 </android.support.v4.widget.DrawerLayout>

你有解决办法吗？我的 ConstraintLayout 与父级不匹配，布局高度是包装内容。

尝试将此添加到布局中的 NestedScrollView

android:layout_height="match_parent"
android:fillViewport="true"
