如何使用导航 ui 组件中的底部工作表对话框

Question

我正在使用导航图进行内部导航。现在我想使用 nav_graph 打开一个底部工作表对话框片段。

我尝试添加

 <dialog
        android:id="@+id/ItemBottomSheetFragment"
        android:name="xxxxxxx.fragments.InvoiceItemBottomSheetFragment"
        tools:layout="@layout/fragment_invoice_item_bottom_sheet"
        android:label="ItemBottomSheetFragment" />

但是当我启动它时，我的应用程序崩溃了。 崩溃报告

Answer 1

之前我使用的是导航 UI 版本 2.0.0

升级到 2.1.0 后，一切正常
