RecyclerView内部抽屉布局



我试图在DrawerLayout中插入RecyclerView，但打开具有设计的活动时应用程序崩溃。

抽屉布局对于NavigationView的工作非常重要。RecyclerView应位于包含工具栏的ConstraintLayout下。

<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawerlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/artboard">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--toolbar-->
<Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
android:orientation="horizontal"
android:paddingStart="15dp"
android:paddingEnd="15dp"
app:layout_constraintTop_toTopOf="parent">
<ImageView
android:id="@+id/menuIcon"
android:layout_width="36dp"
android:layout_height="36dp"
android:src="@drawable/ic_menu"
app:itemIconTint="@color/colorWhite" />
<ImageView
android:id="@+id/cartIcon"
android:layout_width="36dp"
android:layout_height="36dp"
android:layout_gravity="end"
android:src="@drawable/ic_cart" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="22dp"
android:fontFamily="@font/caveat_bold"
android:text="storePerfect"
android:textColor="@color/colorWhite"
android:textSize="26sp" />
</Toolbar>
<!--end of tool bar-->
</androidx.constraintlayout.widget.ConstraintLayout>
<!--        design here-->
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="55dp">
</androidx.recyclerview.widget.RecyclerView>

<com.google.android.material.navigation.NavigationView
android:id="@+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/layout_navigation_header"
app:menu="@menu/navigation_menu" />
</androidx.drawerlayout.widget.DrawerLayout>

如何在不影响其他布局的情况下解决此问题？

我得到错误。。。

活动最终设计

这可能是因为DrawerLayout中有两个以上的子级。抽屉布局只允许的2个子视图

  1. 内容视图
  2. 导航视图

所以你的第一个视图需要是你将在这个布局中显示的内容。将RecylcerView放置在ConstraintLayout中可以解决此问题，您只需要将RecylcerView设置在ConstraintLayout之下。它应该是这样的：

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

android:layout_height="match_parent">

因为您正在手动配置工具栏。请执行以下操作：

  1. 确保应用程序主题没有工具栏。

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

    请注意最后一个字符串NoActionBar

  2. 其次，在活动onCreate中，使用setSupportActionBar(binding.toolbar)配置工具栏

    注意：您也可以使用findViewByID而不是binding

之后，在Android Studio中，单击文件>使缓存无效/重新启动并再次运行应用程序。

这应该可以解决上述问题
如果没有，请发布Main Activity、Theme.xml和所有其他代码。

创建一个新的.xml文件并添加到activity_main.xml中
