android中的menu的背景颜色如何设置？请指教

[yuanjh2001]

android中的menu背景是默认白色的，老板想改成其他颜色的，请各位指点一下，我试了，搞不定，好像要重写LayoutInflater.Factory,但是细节不是太清楚，请指点。

menu中每项都是xml中定义出来的。
可以添加
<item android:id="@+id/happy"
android:title="Happy"
android:icon="@drawable/stat_happy" />

1楼说的对，不过我想要做的是要把menu背景颜色自己定义一下，就是不知道怎么做？

....

  <item android:id="@+id/happy"
  android:title="Happy"
  android:icon="@drawable/stat_happy"
  android:background="#66FFFFFF"/>

background就是颜色

你的方法好像不行，我试了一下，还是不可以

这样可以实现自定义背景，但是聚焦时颜色也不改变了！有点郁闷……
