[Android/Kotlin]Drawer Layout 구현3

1. 헤더 화면 만들기 header_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="190dp"
    android:background="?attr/colorPrimary"
    android:orientation="vertical"
    android:padding="16dp">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="Header Title"
        android:textSize="30sp"
        android:textStyle="bold"
        android:gravity="center"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"
        android:textColor="@android:color/white"/>

</LinearLayout>

2. 메인 화면 구성 activity_main.xml

app:headerLayout 추가

<?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:orientation="vertical"
    tools:context=".MainActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <include layout="@layout/toolbar_layout" />
    </LinearLayout>

	<!-- app:headerLayout 추가  -->
    <com.google.android.material.navigation.NavigationView
        android:id="@+id/navigationView"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/header_layout"
        app:menu="@menu/drawer_menu" />

</androidx.drawerlayout.widget.DrawerLayout>
