抽屉式布局中的RecyclerView

Question

抽屉式布局中的RecyclerView

androidxmlandroid-layoutandroid-recyclerviewdrawerlayout

3

我正在尝试在DrawerLayout中插入RecyclerView，但是打开具有此设计的活动时应用程序会崩溃。

DrawerLayout对于NavigationView的工作非常重要。 RecyclerView应该位于持有ToolBar的ConstraintLayout下方。

<?xml version="1.0" encoding="utf-8"?>

        </Toolbar>

            <!--        design here-->
            <androidx.recyclerview.widget.RecyclerView

    <com.google.android.material.navigation.NavigationView

        app:headerLayout="@layout/layout_navigation_header"
        app:menu="@menu/navigation_menu" />

</androidx.drawerlayout.widget.DrawerLayout>

我怎样才能解决这个问题，而不影响其他布局呢？

由于您正在手动配置工具栏，请执行以下操作：

确保您的应用程序主题没有工具栏。

例如： 在 styles.xml / theme.xml 中它应为：<style name="Theme.AAD" parent="Theme.MaterialComponents.Light.NoActionBar">

请注意最后一个字符串 NoActionBar
其次，在您的活动 onCreate 中，使用 setSupportActionBar(binding.toolbar) 配置您的工具栏

注意：您也可以使用 findViewByID 而不是 binding

之后，在Android Studio中，单击文件 > 无效缓存/重启，并再次运行应用程序。

这应该解决上述问题。
如果没有解决，请发布MainActivity、Theme.xml和所有其他代码。

创建一个新的.xml文件并将其添加到activity_main.xml中。

这是因为您在DrawerLayout中有超过2个子元素。 DrawerLayout仅允许两个子视图，其中包括：

ContentView
NavigationView

所以您的第一个视图需要是要在此布局中显示的内容。将RecylcerView放入ConstraintLayout中即可解决此问题，您只需将RecylcerView设置在ConstraintLayout下方即可。它应该看起来像这样：
