您应该使用navigationView更改内容位置(navigationView必须是最后一个子级)

    <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:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        tools:openDrawer="end">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">
           // Content
        </LinearLayout>

        <com.google.android.material.navigation.NavigationView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="right">
            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent">

            <include layout="@layout/digikala_navigation_drawer_header" android:id="@+id/navigationDrawerHeader"/>
            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/navigationDrawerRecyclerView"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_below="@id/navigationDrawerHeader">

            </androidx.recyclerview.widget.RecyclerView>
            </RelativeLayout>
        </com.google.android.material.navigation.NavigationView>
