Android Selector的使用

Selector 资源文件选择器主要根据状态去跟换颜色或者图片

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android" >    <item        android:color="hex_color"               //颜色值，#RGB,$ARGB,#RRGGBB,#AARRGGBB        android:state_pressed=["true" | "false"]//是否触摸         android:state_focused=["true" | "false"]//是否获得焦点        android:state_selected=["true" | "false"]//是否被状态        android:state_checkable=["true" | "false"]//是否可选        android:state_checked=["true" | "false"]//是否选中        android:state_enabled=["true" | "false"]//是否可用        android:state_window_focused=["true" | "false"] />//是否窗口聚焦</selector>
