通过选择器改变字体颜色

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:color="@color/color_text_selected"/>  
    <!-- not selected -->  
    <item android:state_checked="false" android:color="@color/color_text_normal"/>  
</selector>

item里面  android:color  这个属性没有提示
