根布局应该是
DrawerLayout
,您需要在
DrawerLayout
中移动当前的
ConstraintLayout

布局的框架应类似于:

<?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/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!--  Main screen layout   -->
    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/ThemeOverlay.AppCompat.Dark"
            app:layout_constraintTop_toTopOf="parent" />

    </androidx.constraintlayout.widget.ConstraintLayout>


    <!--  Drawer layout   -->
    <com.google.android.material.navigation.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/navigation_header_layout"
        app:menu="@menu/navigation_menu" />

</androidx.drawerlayout.widget.DrawerLayout>


您可以在主屏幕上的
ConstraintLayout

中构建视图,将抽屉布局置于AppCompat.ImageViewNot working sir上方。当我添加时,物料卡片视图按钮就在后面(app:cardElevation=“0dp”)。但之后,该值按钮不起作用。谢谢,先生,部分工作。我做了这样的文件,按钮现在不在fornt上,但当我按下它时,它不工作XDDD,但我想说谢谢,因为这是一个进步XD@D4rK干得好这个问题可能是
clean(View-View)
有一些问题,您可以在那里调试代码,如果发现问题,您可以打开一个新问题。。。如果您发现问题的答案是正确的,请点击左边的勾号接受答案。是的
clen(View-View)
未使用。这在检验结果中有所体现。谢谢XD
