1、在drawable目录下新建XML文件progressbar_horizontal_red：

2、在values目录下新建XML文件styles：
<?xml version="1.0" encoding="utf-8"?><resources> <style name="progressbarStyle_Horizontal_Red" parent="android:Widget.ProgressBar.Horizontal"> <item name="android:indeterminateOnly">false</item> <item name="android:progressDrawable">@drawable/progressbar_horizontal_red</item> <item name="android:minHeight">12.0dp</item> <item name="android:maxHeight">12.0dp</item> </style></resources>
3、布局文件代码：
<ProgressBarandroid:layout_width="fill_parent"android:layout_height="wrap_content"style="@style/progressbarStyle_Horizontal_Red" />
运行起来之后可以发现水平进度条已经变成红色的了~
