color selector的使用报错问题探讨

目前网上大部分的color selector的方法都如初一则，方法如下

<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:color="#FFF" />
    <item android:state_focused="true" android:color="#FFF" />
    <item android:state_pressed="true" android:color="#FFF" />
    <item android:color="#000" />
</selector></span>

<span style="font-size:14px;"><drawable name="menu_bg_normal">#00000000</drawable>
<drawable name="menu_bg_pressed">#50000000</drawable></span>

<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/stu_menu_bg_pressed"/>
    <item android:drawable="@drawable/stu_menu_bg_normal"/>

</selector></span>
