推荐答案

您需要创建自己的样式以应用于 ActionBar.Android 开发者博客上有一个很棒的教程. 要设置中间进度条的样式，请尝试使用 indeterminateProgressStyle 和 Widget.ProgressBar.Small.这是一个简单的例子.

You'll need to create your own style to apply to the ActionBar. There's a great tutorial on this on the Android Developers Blog. To style the intermediate progress bar, try using indeterminateProgressStyle and Widget.ProgressBar.Small. Here's a quick example.

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

<style name="IndeterminateProgress" parent="@android:style/Widget.ProgressBar">
    <item name="android:indeterminateDrawable">@drawable/ic_launcher</item>
</style>

<style name="ActionBarIPS" parent="@android:style/Widget.ActionBar">
    <item name="android:indeterminateProgressStyle">@style/IndeterminateProgress</item>
    <item name="android:background">@color/white</item>
</style>
