在FloatingActionButton上设置id时抛出InflateException

我在主要活动中添加了一个浮动操作按钮控件：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:minHeight="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>
        <android.support.design.widget.FloatingActionButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|right"
            android:layout_marginRight="@dimen/main_fab_margin"
            android:layout_marginBottom="@dimen/main_fab_margin"
            android:layout_alignParentBottom="true"
            android:layout_alignParentRight="true"
            android:src="@drawable/ic_main_fab"
            app:fabSize="normal"
            app:backgroundTint="@color/color_primary"
            app:elevation="@dimen/main_fab_elevation"/>
    </RelativeLayout>

    <!-- Pull-out navigation drawer (a.k.a hamburger menu) -->
    <android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:menu="@menu/navigationmenu"
        app:headerLayout="@layout/drawerheader" />

</android.support.v4.widget.DrawerLayout>

这会抛出一个类似于：

的InflateException 
Android.Views.InflateException: Binary XML file line #17: Binary XML file line #17: Error inflating class android.support.design.internal.NavigationMenuItemView

浮动操作按钮是RelativeLayout的子项，它是android.support.v4.widget.DrawerLayout的子项。

现在是奇怪的部分，当我删除

android:id="@+id/main_fab"

从上面的代码中，一切都很完美。

我不知道是什么原因引起的。我真的需要为按钮设置一个id，这样我就可以控制代码隐藏中的点击次数。

有什么想法吗？

答案 0 :(得分：1)

尝试核对obj/bin个文件夹，重新启动IDE，然后进行干净部署。 （即adb uninstall packagename）。关于Error inflating class android.support.design.internal.NavigationMenuItemView，我经常看到这个问题，似乎已经解决了这个问题。

我认为这是一个Xamarin特定的错误，直到我在Native Java中遇到它。基本上按照相同的步骤解决了这两个领域的问题。
