这是download_progress(要更改进度条的样式，请使用您自己的android:progressDrawable)

This is the download_progress (and to change the style of the progress bar, use your own android:progressDrawable)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:padding="5dp">

<TextView android:id="@+id/status_text" android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:layout_alignParentTop="true"
    android:text="@string/download_notification_message" />

<ProgressBar android:id="@+id/status_progress"
    android:layout_width="fill_parent" android:layout_height="5dp"
    android:layout_below="@id/status_text"
    android:layout_marginTop="10dp"
    android:progressDrawable="@drawable/notification_progress_bar"
    style="@android:style/Widget.ProgressBar.Horizontal"
    android:indeterminate="false" android:indeterminateOnly="false" />   </RelativeLayout> 

notification_progress_bar:

<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android">   
 <item android:id="@android:id/background">
    <shape>
        <gradient
                android:startColor="#000001"
                android:centerColor="#0b131e"
                android:centerY="0.75"
                android:endColor="#0d1522"
                android:angle="270"
        />
    </shape>
</item>
<item android:id="@android:id/secondaryProgress">
    <clip>
        <shape>
            <gradient
                    android:startColor="#234"
                    android:centerColor="#234"
                    android:centerY="0.75"
                    android:endColor="#a24"
                    android:angle="270"
            />
        </shape>
    </clip>
</item>

<item  
    android:id="@android:id/progress">  
    <clip>  
        <shape>   
            <gradient  
                    android:startColor="#44000000"  
                    android:centerColor="#44000000"  
                    android:centerY="0.75"  
                    android:endColor="#44000000"  
                    android:angle="270"  
            />  
        </shape>  
    </clip>  
</item>
