Android ActionBarSherlock在按下时更改项目的颜色

Question

我不明白如何在ActionBarSherlock中更改按下的项目的颜色。我正在覆盖主题Widget.Sherlock.Light.ActionBar.Solid.Inverse，当我看到这个主题的来源时，我找不到我的项目按下时的蓝色。 有人能帮助我吗？

有一个样式属性负责ActionButton背景： actionBarItemBackground 。只需将您自己定义的DrawableStateList设置为值即可。

例如，这是默认的DrawableStateList：

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<!-- Even though these two point to the same resource, have two states so the drawable will invalidate itself when coming out of pressed state. -->
<item android:state_focused="true"  android:state_enabled="false" android:state_pressed="true" android:drawable="@drawable/abs__list_selector_disabled_holo_dark" />
<item android:state_focused="true"  android:state_enabled="false"                              android:drawable="@drawable/abs__list_selector_disabled_holo_dark" />
<item android:state_focused="true"                                android:state_pressed="true" android:drawable="@drawable/abs__list_selector_background_transition_holo_dark" />
<item android:state_focused="false"                               android:state_pressed="true" android:drawable="@drawable/abs__list_selector_background_transition_holo_dark" />
<item android:state_focused="true"                                                             android:drawable="@drawable/abs__list_focused_holo" />
<item                                                                                          android:drawable="@android:color/transparent" />
