안드로이드 스튜디오 event 처리 3

커스텀 버튼

동그라미 쳐진 부분에 이미지 파일을 넣어 줍니다.

drawable 좌클릭후 리소스 파일을 새로 만들어 줍니다. (이 파일의 이름을 잘 기억 하세요)

 

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/android_pressed"
        android:state_pressed="true"/>
    <item android:drawable="@drawable/android_focused"
        android:state_focused="true"/>
    <item android:drawable="@drawable/android_normal"/>
</selector>
