本文介绍如何使用Android自定义通知栏中的进度条样式，包括设置进度条的最大值、当前值及是否只显示不确定进度等属性，并通过代码实现动态更新进度。

     <ProgressBar
            android:id="@+id/custom_progressbar"
            style="@style/StyleProgressBarMini"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
        android:background="@drawable/shape_progressbar_bg"
            android:max="100"
            android:progress="0" />

    <!-- progressbar -->
    <style name="StyleProgressBarMini" parent="@android:style/Widget.ProgressBar.Horizontal">
        <item name="android:maxHeight">20dip</item>
        <item name="android:minHeight">5dip</item>
        <item name="android:indeterminateOnly">false</item>
        <item name="android:indeterminateDrawable">@android:drawable/progress_indeterminate_horizontal</item>
        <item name="android:progressDrawable">@drawable/shape_progressbar_mini</item>
    </style>

//@drawable/shape_progressbar_mini

            <corners android:radius="5dip" />

            <gradient
                android:angle="270"
                android:centerY="0.75"

    </item>
    <item android:id="@android:id/secondaryProgress">

    <item android:id="@android:id/progress">
