Additional toolbar at the bottom with Scroll View

问题

I want to have an additional Toolbar with elements in it (like a back button and another button to directly go into a certain activity) at the bottom of the layout. The problem is that I use a Scroll View inside a Constraint Layout. How can I insert such a layout file? I tried it by drag and dropping a toolbar in the Scroll View. However, as the Scroll View is bigger than the layout in the layout editor of Android Studio, I did not know where to put it. It is also important that the two toolbars should be fixed. So whenever I scroll down, the toolbars should be visible all the time.

Update: Does nobody have an idea. I am still struggling with that.

Here is the design I want to have (in a first step without any buttons):

以下是如何安排视图的方法。这是来自Android Studio设计师的示例:
_scrollView_ 是一个 _NestedScrollView_。
_scrollView_ 将独立滚动,工具栏将保持在原位(具有适当的约束条件)。类似这样:
```xml
<?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="顶部工具栏"
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>

这是结果的示例:

Here is how to arrange the views. This is from the Android Studio designer:

底部附加工具栏与滚动视图

The scrollingView is a NestedScrollView.

scrollingView will scroll independently of the toolbars and the toolbars will stay in place (with the proper constraints.) Something like this:

&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
&lt;android.support.constraint.ConstraintLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
xmlns:app=&quot;http://schemas.android.com/apk/res-auto&quot;
xmlns:tools=&quot;http://schemas.android.com/tools&quot;
android:layout_width=&quot;match_parent&quot;
android:layout_height=&quot;match_parent&quot;
tools:context=&quot;.MainActivity&quot;&gt;
&lt;android.support.v7.widget.Toolbar
android:id=&quot;@+id/toolbar_mainActivity&quot;
android:layout_width=&quot;0dp&quot;
android:layout_height=&quot;wrap_content&quot;
android:background=&quot;#435cb53f&quot;
android:theme=&quot;@style/ThemeOverlay.AppCompat.ActionBar&quot;
app:layout_constraintEnd_toEndOf=&quot;parent&quot;
app:layout_constraintStart_toStartOf=&quot;parent&quot;
app:layout_constraintTop_toTopOf=&quot;parent&quot;
app:popupTheme=&quot;@style/ThemeOverlay.AppCompat.Light&quot;
app:title=&quot;Top Toolbar&quot;
app:titleTextColor=&quot;@android:color/black&quot; /&gt;
&lt;android.support.v4.widget.NestedScrollView
android:id=&quot;@+id/scrollingView&quot;
android:layout_width=&quot;0dp&quot;
android:layout_height=&quot;0dp&quot;
app:layout_constraintBottom_toTopOf=&quot;@id/bottomToolbar&quot;
app:layout_constraintEnd_toEndOf=&quot;parent&quot;
app:layout_constraintStart_toStartOf=&quot;parent&quot;
app:layout_constraintTop_toBottomOf=&quot;@id/toolbar_mainActivity&quot;&gt;
&lt;android.support.v7.widget.LinearLayoutCompat
android:layout_width=&quot;match_parent&quot;
android:layout_height=&quot;wrap_content&quot;&gt;
&lt;TextView
android:id=&quot;@+id/textView_ToolBar_CocktailSelectionActivity&quot;
android:layout_width=&quot;match_parent&quot;
android:layout_height=&quot;wrap_content&quot;
android:layout_margin=&quot;8dp&quot;
android:text=&quot;@string/material&quot;
android:textColor=&quot;@android:color/black&quot;
android:textSize=&quot;24sp&quot; /&gt;
&lt;/android.support.v7.widget.LinearLayoutCompat&gt;
&lt;/android.support.v4.widget.NestedScrollView&gt;
&lt;android.support.constraint.ConstraintLayout
android:id=&quot;@+id/bottomToolbar&quot;
android:layout_width=&quot;0dp&quot;
android:layout_height=&quot;wrap_content&quot;
app:layout_constraintBottom_toBottomOf=&quot;parent&quot;
app:layout_constraintEnd_toEndOf=&quot;parent&quot;
app:layout_constraintStart_toStartOf=&quot;parent&quot;&gt;
&lt;ImageButton
android:id=&quot;@+id/imageButton&quot;
android:layout_width=&quot;210dp&quot;
android:layout_height=&quot;128dp&quot;
android:background=&quot;#00000000&quot;
android:scaleType=&quot;fitCenter&quot;
app:layout_constraintBottom_toBottomOf=&quot;parent&quot;
app:layout_constraintStart_toStartOf=&quot;parent&quot;
app:srcCompat=&quot;@mipmap/ic_launcher&quot; /&gt;
&lt;ImageButton
android:id=&quot;@+id/imageButton2&quot;
android:layout_width=&quot;210dp&quot;
android:layout_height=&quot;128dp&quot;
android:background=&quot;#00000000&quot;
android:scaleType=&quot;fitCenter&quot;
app:layout_constraintBottom_toBottomOf=&quot;parent&quot;
app:layout_constraintEnd_toEndOf=&quot;parent&quot;
app:srcCompat=&quot;@mipmap/ic_launcher&quot; /&gt;
&lt;/android.support.constraint.ConstraintLayout&gt;
&lt;/android.support.constraint.ConstraintLayout&gt;
