Render problem with Collapse Toolbar Layout

Question

I have the project and one of fragment use the Collapse Toolbar Layout. Until recently, everything was fine. But last time i faced in Android Studio with the problem of render of the Collapse Toolbar Layout. For example below the example of layout:

<androidx.coordinatorlayout.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">

<com.google.android.material.appbar.AppBarLayout
    android:id="@+id/appBarLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <com.google.android.material.appbar.CollapsingToolbarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_scrollFlags="scroll|snap|exitUntilCollapsed"
        app:title="@string/app_name">

        
        <ImageView
            android:layout_width="match_parent"
            android:layout_height="250dp"
            android:scaleType="centerCrop"
            android:src="@drawable/favorite"
            app:layout_collapseMode="parallax" />
        
        <androidx.appcompat.widget.Toolbar
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_collapseMode="pin"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Dark" />

    </com.google.android.material.appbar.CollapsingToolbarLayout>

</com.google.android.material.appbar.AppBarLayout>

<androidx.core.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">
    
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:lineSpacingExtra="8sp"
        android:padding="16dp"
        android:text="this is text"
        android:textSize="20sp" />
</androidx.core.widget.NestedScrollView> </androidx.coordinatorlayout.widget.CoordinatorLayout>

The problem is that NestedScrollView hidden after rendering in Android Studio and sometime appear when i remove next prompt:

app:layout_behavior="@string/appbar_scrolling_view_behavior"

But it appear in the left-top corner of fragment. Android Studio shows the next error:

What i had did:

• invalidate caches
• clean and rebuild the project

Also i tried create new empty project and test the layout code in it and new project work correctly.

Please let me know how i can resolve this problem?

Answer 1

I had the same problem. Here is my solution for the preview bug:

tools:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior"

Include the line inside your "com.google.android.material.appbar.AppBarLayout"
