android - 将gradle版本3.6.0升级到最新的4.1.0后出现android view inflate异常（仅在更新应用程序时发生异常）

Question

将 Gradle 版本 3.6.0 升级到最新的 4.1.0 后，我得到一个 android view inflate 异常。仅当从现有版本升级到新版本时才会发生这种情况。全新安装一切正常。

<com.google.android.material.appbar.AppBarLayout
                    
    android:id="@+id/appBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
                
                    <RelativeLayout
                        android:id="@+id/toolbarrel"
                        android:layout_width="match_parent"
                        android:layout_height="?attr/actionBarSize">
                        <androidx.appcompat.widget.Toolbar
                            android:id="@+id/toolbar"
                            android:layout_width="match_parent"
                            android:layout_height="?attr/actionBarSize"
                            android:background="?attr/colorPrimary"
                            app:layout_scrollFlags="scroll|enterAlways"
                            app:titleTextColor="?attr/titleColor"
                            android:paddingLeft="?attr/actionBarSize"
                            />
                      </RelativeLayout>
                
                
</com.google.android.material.appbar.AppBarLayout>
