how to show horizontal and vertical gradient divider line?

I am little good at coding but when it comes to designing part in android, I always cannot make it out. gradient color works at vertical but not in horizontal. Can anyone suggest me how to get those divider on horizontal line to whole item like in vertical?

my divider.xml

   <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

<gradient
    android:angle="0"
    android:endColor="@android:color/white"
    android:centerColor="#000"
    android:startColor="@android:color/white"
    android:type="linear" />

</shape>

Solution

What about using line instead ? :

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">



<item android:top="-5dp" android:right="-5dp" android:left="-5dp">
    <shape>
        <stroke android:color="@android:color/transparent" />
        <stroke
            android:width=".8dp"
            android:color="@color/black" />

    </shape>

</item>

the above divider for vertical one, and this for horizontal one :

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">



    <item android:top="-5dp" android:bottom="-5dp" android:left="-5dp">
        <shape>
            <stroke android:color="@android:color/transparent" />
            <stroke
                android:width=".8dp"
                android:color="@color/company_color" />

        </shape>

    </item>

</layer-list>

try with your own width.

OR remove this line from your current divider android:centerColor="#000"
