自定义的 notification layouts

Question

我想创建资源如下：
res/values/styles.xml

<resources>
    <style name="NotificationTitle">
      <item name="android:textColor">?android:attr/textColorPrimaryInverse</item>
      <item name="android:textStyle">bold</item>
    </style>
    <style name="NotificationText">
      <item name="android:textColor">?android:attr/textColorPrimaryInverse</item>
    </style>
</resources>

res/values-v9/styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="NotificationText" parent="android:TextAppearance.StatusBar.EventContent" />
    <style name="NotificationTitle" parent="android:TextAppearance.StatusBar.EventContent.Title" />
</resources>

但是对于 values-v9，有下面的错误：

error: Error retrieving parent for item: No resource found that matches the given name
'android:TextAppearance.StatusBar.EventContent.Title'.

为什么啊？

Answer 1

我估计是由于父类属性的错误格式造成的：

<style name="NotificationText" parent="@android:style/TextAppearance.StatusBar.EventContent" />
    <style name="NotificationTitle" parent="@android:style/TextAppearance.StatusBar.EventContent.Title" />
