Answer 1

这很简单：）

actionBar.setStackedBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.color_brown_dark)));

在您的情况下，

或更简单：

actionBar.setBackgroundDrawable(new ColorDrawable("FF0000"));

Answer 2

以您的风格添加：

   <style name="MyTheme" parent="android:Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/MyActionBarStyle</item>
   </style>

   <style name="MyActionBarStyle" parent="@android:style/Widget.Holo.Light.ActionBar.Solid">
     <item name="android:backgroundStacked">@drawable/my_stacked_background</item>
   </style>**
