values 폴더 안에 color를 만들거나 colors 안에 밑에 색을 입력을 해주세요! 참고로 values 폴더 파일을 만들려면 values에서 오른쪽 마우스 클릭 후
new->XML->Values XML File에서 만들어주세요.

색은 일단 #000000으로 잡고 번호선? 옆에 정사각형으로 그 색이 나와요. 그 사각형을 클릭하시고 변경해주셔도 괜찮습니다~

pressed는 눌렀을 때 나오는 버튼, focused는 초점이 맞추어졌을 때 맨 밑은 그냥 화면에 보이는, 즉 버튼을 눌리지 않았을 때 보이는 버튼입니다.


마지막으로 버튼에 "@drawable/selector" 추가하면 완성!
