Android-Color State List用于控件在各状态下的文本颜色显示

 

该颜色状态列表只对控件文本颜色起作用，作为android:textColor的属性值来使用，用作控件的android:background属性将不起作用，需要用drawable state list取代color state list.

文件位置:
res/color/filename.xml
filename将用作 resource ID.
资源引用:
In Java: R.color.filename
In XML: @[package:]color/filename
定义:

12345678910111213

    <?xml version="1.0" encoding="utf-8"?>    <selector xmlns:android="http://schemas.android.com/apk/res/android" >        <item            android:color="hex_color"            android:state_pressed=["true" | "false"]            android:state_focused=["true" | "false"]            android:state_selected=["true" | "false"]            android:state_active=["true" | "false"]            android:state_checkable=["true" | "false"]            android:state_checked=["true" | "false"]            android:state_enabled=["true" | "false"]            android:state_window_focused=["true" | "false"] />    </selector>

实例:
XML 文件存放位置 res/color/button_text.xml:

12345678

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:state_pressed="true"          android:color="#ffff0000"/> <!-- pressed -->    <item android:state_focused="true"          android:color="#ff0000ff"/> <!-- focused -->    <item android:color="#ff000000"/> <!-- default --></selector>
