Дополнительная панель инструментов внизу с прокруткой

Question

Я хочу иметь дополнительную панель инструментов с элементами в ней (например, заднюю кнопку и другое основание для прямого go в определенное действие) внизу макета. Проблема в том, что я использую вид прокрутки внутри схемы ограничений. Как я могу вставить такой файл макета. Я попробовал это путем перетаскивания панели инструментов в представлении прокрутки. Однако, поскольку представление прокрутки больше, чем макет в редакторе макетов Android Studio, я не знал, где его разместить. Также важно, чтобы две панели инструментов были зафиксированы. Поэтому, когда я прокручиваю вниз, панели инструментов должны быть видны постоянно.

Обновление: ни у кого нет идеи. Я все еще борюсь с этим

Вот дизайн, который я хочу иметь (на первом шаге без всяких нижних частей):

Здесь вы можете увидеть код файла макета XML:

Answer 2

Вот как упорядочить виды. Это от Android Studio Designer:

scrollingView является NestedScrollView .

scrollingView будет прокручиваться независимо от панелей инструментов, и панели инструментов будут оставаться на месте (с надлежащими ограничениями). Примерно так:

<?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"
    tools:context=".MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar_mainActivity"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="#435cb53f"
        android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:title="Top Toolbar"
        app:titleTextColor="@android:color/black" />

    <android.support.v4.widget.NestedScrollView
        android:id="@+id/scrollingView"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintBottom_toTopOf="@id/bottomToolbar"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@id/toolbar_mainActivity">

        <android.support.v7.widget.LinearLayoutCompat
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <TextView
                android:id="@+id/textView_ToolBar_CocktailSelectionActivity"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_margin="8dp"
                android:text="@string/material"
                android:textColor="@android:color/black"
                android:textSize="24sp" />
        </android.support.v7.widget.LinearLayoutCompat>
    </android.support.v4.widget.NestedScrollView>

    <android.support.constraint.ConstraintLayout
        android:id="@+id/bottomToolbar"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent">

        <ImageButton
            android:id="@+id/imageButton"
            android:layout_width="210dp"
            android:layout_height="128dp"
            android:background="#00000000"
            android:scaleType="fitCenter"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:srcCompat="@mipmap/ic_launcher" />

        <ImageButton
            android:id="@+id/imageButton2"
            android:layout_width="210dp"
            android:layout_height="128dp"
            android:background="#00000000"
            android:scaleType="fitCenter"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:srcCompat="@mipmap/ic_launcher" />

    </android.support.constraint.ConstraintLayout>
</android.support.constraint.ConstraintLayout>

Это результат:
