Android NavigationView仅单击小区域

我已经从android studio创建了带有菜单的默认模板。此项目正在运行，但有时用户只能在小范围内单击菜单：

但有时菜单中的所有项都可以正常工作（每个项都有正常的单击侦听器区域），这是随机发生的

也许有人有这个问题，我不明白为什么会发生

我的代码：

xml

<android.support.design.widget.NavigationView

    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/view_nav_header_main"
    app:menu="@menu/activity_main_drawer" />

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
