【问题描述】：
我尝试在产品上添加子菜单，但应用程序在启动时崩溃。问题来自创建的子菜单。我不明白为什么。
导航菜单.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/nav_home"
android:title="Home" />
<item android:title="Products"
android:id="@+id/nav_products">
<menu>
<item android:id="@+id/nav_tubeBendingMachines"
android:title="Tub" />
<item android:id="@+id/nav_sectionBendingRolls"
android:title="Sect" />
</menu>
</item>
<item android:id="@+id/nav_tube_data"
android:title="Tube Data" />
<item android:id="@+id/nav_tool_setup"
android:title="Tool Setup" />
<item android:id="@+id/nav_mandrel"
android:title="Mandrel" />
<item android:id="@+id/nav_archive"
android:title="Archive" />
<item android:id="@+id/nav_tool_notes"
android:title="Tool Notes" />
<item android:id="@+id/nav_converter"
