TextView state_pressed/state_focused/state_selected样式更改

Question

我正在尝试根据其状态更改TextView样式.我的styles.xml包含:

<style name="text_normal_ops">  
    <item name="android:gravity">left</item>  
    <item name="android:textColor">@color/text_usual_color</item> 
    <item name="android:textStyle">bold</item>  
</style>  
<style name="text_normal_ops_pressed">  
    <item name="android:gravity">left</item>  
    <item name="android:textColor">@color/text_pressed</item>  
    <item name="android:textStyle">bold</item>  
</style>

我的selector(text_ops.xml)定义为:

<selector xmlns:android="http://schemas.android.com/apk/res/android">  
    <item android:state_pressed="true" style="@style/text_normal_ops_pressed" />  
    <item android:state_focused="true" style="@style/text_normal_ops_pressed" />  
    <item android:state_selected="true" style="@style/text_normal_ops_pressed" />  
    <item style="@style/text_normal_ops"/>  
</selector>

但是当我将它应用到我的textview(style="@drawable/text_ops")时,它不起作用.有小费吗？
谢谢

在Android中,据我所知,只有两个状态列表1.颜色状态列表资源2. StateListDrawable.如果您正在使用其中的样式,请重新检查文档
