我有项目和一个片段使用折叠布局.直到最近,一切都很好.但最后一次我面对在Android Studio与折叠布局的渲染问题.例如下面的布局的例子:
<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>
字符串
问题是NestedScrollView在Android Studio中渲染后隐藏,有时会在我删除下一个提示时出现:
app:layout_behavior="@string/appbar_scrolling_view_behavior”
但它出现在片段的左上角。Android Studio显示下一个错误:

型
我所做的:
- 无效高速缓存
- 清理和重建项目
我还尝试创建新的空项目,并测试它的布局代码和新项目的工作正确。
请告诉我如何解决这个问题?

我也遇到了同样的问题。下面是我对预览错误的解决方案:
tools:layout_behavior=“com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior”
在你的“com.google.android.material.appbar.AppBarLayout”中包含这一行
