안드로이드 BottomNavigationView 아이콘 설정

1. res 폴더에 menu 폴더를 만들고 home.xml을 만든다.

 

2. home.xml  설정

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/homeItem"
        android:icon="@drawable/baseline_home_black_24dp" //1번째 아이콘
        android:title="Home"/>
    <item
        android:id="@+id/historyItem"
        android:icon="@android:drawable/ic_menu_recent_history"  //2번째 아이콘
        android:title="History"/>
    <item
        android:id="@+id/userItem"
        android:icon="@drawable/round_perm_identity_black_24dp"  //3번째 아이콘
        android:title="User"/>

</menu>

 

3.  activity_main.xml 설정 (ConstraintLayout으로 설정해야한다)

<com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/navigationView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?android:attr/windowBackground"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toLeftOf="parent"
        app:menu="@menu/home" />   //메뉴 등록
