Use ‘inset‘.....
(list_divider.xml)
<?xml version="1.0" encoding="UTF-8"?> <inset xmlns:android="http://schemas.android.com/apk/res/android" android:insetLeft="50dp" android:insetRight="50dp" > <shape> <solid android:color="@color/orange" /> <corners android:radius="2.0dip" /> </shape> </inset>
and in your list view add like this...
<ListView android:dividerHeight="2dp" android:divider="@drawable/list_divider" ... />
you can set the inset value as desired...
