你可以把你的菜單XML文件與完整的代碼？ –

產生的原因：android.view.InflateException: Binary XML file line #38: Binary XML file line #38: Error inflating clas小號 android.support.design.widget.NavigationView

造成的： android.view.InflateException: Binary XML file line #38: Error inflating class android.support.design.widget.NavigationView

原因：

的問題是在你的NavigationMenu.xml。項目nav_settings導致InflateException。發生這種情況的原因是item有icon但上面的items沒有icons而你沒有grouped它們在一起。

SOLUTION：

爲了解決這個InflateException，把菜單項nav_tube_data到nav_contact爲group和也你必須給一個id到group。

這裏是工作的XML代碼：

<?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> 

    <group 
     android:checkableBehavior="none" 
     android:id="@+id/group_one"> 

     <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" 
      android:title="Converter" /> 

     <item android:id="@+id/nav_bend_guide" 
      android:title="Bend Guide" /> 

     <item android:id="@+id/nav_contact" 
      android:title="Contact Us" /> 
    </group> 

    <item android:id="@+id/nav_settings" 
     android:title="Settings" 
     android:icon="@drawable/ic_settings_black_24dp"/> 

</menu>

OUTPUT：

enter image description here

一個建議，不要把你的資源icons在mipmap文件夾中。 mipmap只適用於launcher圖標。對於其他resource圖標，您應該使用drawable文件夾。

UPDATE：

我想點擊Products和它去表示與Products所有 項目的頁面。沒有辦法使產品clickable 像首頁等其他項目...？

試試這個：

.................. 
    ............................. 
    <group 
     android:checkableBehavior="none" 
     android:id="@+id/group_two"> 

     <item android:title="Products" 
      android:id="@+id/nav_products" /> 

     <item android:id="@+id/nav_tubeBendingMachines" 
      android:title="Tub" /> 

     <item android:id="@+id/nav_sectionBendingRolls" 
      android:title="Sect" /> 
    </group> 
    ................ 
    .......................

希望這將有助於〜
