android 自定义进度条颜色
先看图
基于产品经理各种自定义需求，经过查阅了解，下面是自己对android自定义进度条的学习过程！
这个没法了只能看源码了，还好下载了源码， sources\base\core\res\res\ 下应有尽有，修改进度条颜色只能找progress ,因为是改变样式，首先找styles.xml
找到xml后，进去找到
[html]view plaincopyprint?<spanstyle="font-size:18px;"><stylename="Widget.ProgressBar"> <itemname="android:indeterminateOnly">true</item> <itemname="android:indeterminateDrawable">@android:drawable/progress_medium_white</item> <itemname="android:indeterminateBehavior">repeat</item> <itemname="android:indeterminateDuration">3500</item> <itemname="android:minWidth">48dip</item> <itemname="android:maxWidth">48dip</item> <itemname="android:minHeight">48dip</item> <itemname="android:maxHeight">48dip</item> </style></span>[html]view plaincopyprint?<spanstyle="font-size:18px;"><stylename="Widget.ProgressBar"> <itemname="android:indeterminateOnly">true</item> <itemname="android:indeterminateDrawable">@android:drawable/progress_medium_white</item> <itemname="android:indeterminateBehavior">repeat</item> <itemname="android:indeterminateDuration">3500</item> <itemname="android:minWidth">48dip</item> <itemname="android:maxWidth">48dip</item> <itemname="android:minHeight">48dip</item> <itemname="android:maxHeight">48dip</item> </style></span>
这是默认转圈的效果style，但今天我们修改的是水平进度条颜色！
所以找到
[html]view plaincopyprint?<spanstyle="font-size:18px;"><stylename="Widget.ProgressBar.Horizontal"> <itemname="android:indeterminateOnly">false</item> <itemname="android:progressDrawable">@android:drawable/progress_horizontal</item> <itemname="android:indeterminateDrawable">@android:drawable/progress_indeterminate_horizontal</item> <itemname="android:minHeight">20dip</item> <itemname="android:maxHeight">20dip</item> </style></span>[html]view plaincopyprint?<spanstyle="font-size:18px;"><stylename="Widget.ProgressBar.Horizontal"> <itemname="android:indeterminateOnly">false</item> <itemname="android:progressDrawable">@android:drawable/progress_horizontal</item> <itemname="android:indeterminateDrawable">@android:drawable/progress_indeterminate_horizontal</item> <itemname="android:minHeight">20dip</item> <itemname="android:maxHeight">20dip</item> </style></span>
你看系统一步一步关联的，扩展性很性，低耦合，所以我们现在只要改变进度条是怎么样画出来的就行了 ，但是负责画进度条的是
<item name="android:progressDrawable"> 所以我们可以找到"drawable下的 progress_horizontal 文件，改变他就可以改变进度条颜色

看到没有，这是系统的进度条画出的布局条件
android:startColor="#80ffd300"
android:centerColor="#80ffb600"
android:endColor="#ff747674"
我们只要改变这个色值就能改变他的颜色，主要改变的是<item android:id="@android:id/progress">下的色值就行了
说了这么多，到底怎么做呢， 很简单
1 。 在我们的项目下新建一个 style.xml 文件
创建一个style 标签，集成系统默认样式，然后自定义一个新的progressDrawable 文件，随后面在layout 中的progress 中引用这个文件就行
<style name="ProgressBar_Mini"parent="@android:style/Widget.ProgressBar.Horizontal">
<item name="android:maxHeight">50dip</item>
<item name="android:minHeight">8dip</item>
<item name="android:indeterminateOnly">false</item>
<item name="android:indeterminateDrawable">@android:drawable/progress_indeterminate_horizontal</item>
<item name="android:progressDrawable">@drawable/progressbar_mini</item>
</style>
下面是我的progressbar_mini 文件，改变了下android:endColor="#F5F5F5" android:startColor="#BEBEBE" 的色值
[java]view plaincopyprint?<spanstyle="font-size:18px;"><layer-listxmlns:android="/apk/res/android"> <itemandroid:id="@android:id/background"> <shape> <cornersandroid:radius="5dip"/> <gradient android:angle="270" android:centerY="0.75" android:endColor="#F5F5F5" android:startColor="#BEBEBE"/> </shape> </item> <itemandroid:id="@android:id/secondaryProgress"> <clip> <shape> <cornersandroid:radius="0dip"/> <gradient android:angle="270" android:centerY="0.75" android:endColor="#165CBC" android:startColor="#85B0E9"/> </shape> </clip> </item> <itemandroid:id="@android:id/progress"> <clip> <shape> <cornersandroid:radius="5dip"/> <gradient android:angle="270" android:centerY="0.75" android:endColor="#165CBC" android:startColor="#85B0E9"/> </shape> </clip> </item> </layer-list></span>[java]view plaincopyprint?<spanstyle="font-size:18px;"><layer-listxmlns:android="/apk/res/android"> <itemandroid:id="@android:id/background"> <shape> <cornersandroid:radius="5dip"/> <gradient android:angle="270" android:centerY="0.75" android:endColor="#F5F5F5" android:startColor="#BEBEBE"/> </shape> </item> <itemandroid:id="@android:id/secondaryProgress"> <clip> <shape> <cornersandroid:radius="0dip"/> <gradient android:angle="270" android:centerY="0.75" android:endColor="#165CBC" android:startColor="#85B0E9"/> </shape> </clip> </item> <itemandroid:id="@android:id/progress"> <clip> <shape> <cornersandroid:radius="5dip"/> <gradient android:angle="270" android:centerY="0.75" android:endColor="#165CBC" android:startColor="#85B0E9"/> </shape> </clip> </item> </layer-list></span>
最后在中引用就可以了
<ProgressBar
android:id="@+id/progress"
style="@style/ProgressBar_Mini"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:progress="50" />
