uild.gradle (app) 에 라이브러리 추가하기
DrawerLayout은 Support Library v4에 포함된 클래스이므로 build.gradle (Module: app)에 Support Library를 추가한다.

android {
          :
  dependencies {
          :
    implementation 'androidx.legacy:legacy-support-v4:1.0.0' // DrawerLayout
    implementation 'com.google.android.material:material:1.0.0' // NavigationView
