推荐答案

之所以酒吧是彩色的，因为你选择的风格。这是一个固定式的，并使用系统主题UI元素的代

The reason why the bar is of that color is because of the style you have selected. That is a fixed style and uses the system themes for the generation of UI elements.

看从<一个源$ C ​​$ C href="http://www.google.com/$c$csearch/p?hl=en#uX1GffpyOZk/core/res/res/values/themes.xml&q=progressBarStyleSmall&d=3">here.这progressBarStyleSmall属性使用定义的<一个样式href="http://www.google.com/$c$csearch/p?hl=en#uX1GffpyOZk/core/res/res/values/styles.xml&q=progressBarStyleSmall&d=3">here.

Look at the source code from here. This progressBarStyleSmall attribute uses the styles defined here.

<style name="Widget.ProgressBar.Small">
    <item name="android:indeterminateDrawable">@android:drawable/progress_small_white</item>
    <item name="android:minWidth">16dip</item>
    <item name="android:maxWidth">16dip</item>
    <item name="android:minHeight">16dip</item>
    <item name="android:maxHeight">16dip</item>
</style>

只要创建以下的Andr​​oid源$ C ​​$ c中的例子自定义样式。您将需要更换的android：indeterminateDrawable你想要什么

Just create a custom style following the example from the android source code. You would need to replace the android:indeterminateDrawable to what you want.
