CodePudding user response：

There was issue in your xml design and I checked the code you are using drawerlayout with wrap_content instead of match_parent which is causing the crash. I modified your code which is running properly without any error. Below is your modified code:

 <?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"

    android:id="@ id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">
<include
    layout="@layout/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"></include>

<com.google.android.material.navigation.NavigationView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="@color/white"
    android:fitsSystemWindows="true">


    <RelativeLayout

            android:id="@ id/header"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_alignParentTop="true"
            android:layout_gravity="top"
            android:src="@mipmap/ic_launcher"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.0"
