如何在Android xml drawables中绘制带圆角的线条(How to draw Line with rounded corners in Android xml drawables)

 我想在带有圆角的XML绘制一条线。我没有得到如何创建它。我想将此行用于Seekbar 。 我想像矩形那样为线条提供圆角。 
 
<?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 android:shape="line">
        <stroke
            android:width="5dp"
            android:color="#7b7878" />
    </shape>
</item>
<item android:id="@android:id/progress">
    <clip>
        <shape android:shape="line">
            <stroke
                android:width="5dp"
                android:color="#FF0000" />
        </shape>
    </clip>
</item>
 

I want to draw a line in the XML with rounded corners.I am not getting how to create that.I want to use this line for the Seekbar. I want to give rounded corners to the line just like rectangle.
 
<?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 android:shape="line">
        <stroke
            android:width="5dp"
            android:color="#7b7878" />
    </shape>
</item>
<item android:id="@android:id/progress">
    <clip>
        <shape android:shape="line">
            <stroke
                android:width="5dp"
                android:color="#FF0000" />
        </shape>
    </clip>
</item>
