Android Selector 와 Shape 의 사용법

1.배경 선택 기(res/drawable/,사용 방법:android:background="@drawable/XXX")

 
<?xml version="1.0" encoding="utf-8"?> 
<selectorxmlns:android="http://schemas.android.com/apk/res/android"> 
<itemandroid:drawable="@drawable/login_blue_pressed" android:state_pressed="true"/> 
<itemandroid:drawable="@drawable/login_blue_pressed"android:state_focused="true"/> 
<itemandroid:drawable="@drawable/login_blue_normal" /> 
</selector> 

2.텍스트 색상 선택 기(res/color/,사용 방법:android:textColor="@color/XXX")

 
<?xml version="1.0" encoding="utf-8"?> 
<selectorxmlns:android="http://schemas.android.com/apk/res/android"> 
<itemandroid:color="#ffffff" android:state_pressed="true"/> 
<itemandroid:color="#ffffff" android:state_focused="true"/> 
<item android:color="#000000"/> 
</selector> 

주의:res/drawable/XXX.xml 스마트 제시 시 android:color 가 없습니다.같은 이치 로 res/color/XXX.xml 스마트 알림 에 android:drawable 이 없습니다.3.배경 그 라 데 이 터 는 res/color/또는 res/drawable/)res/drawable/selector 1.xml:

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