In your ListView change the divider color

            android:divider="#F0F0F0" //grey color
            android:dividerHeight="15dp"

Create a new XML file,

res/drawable/list_divider.xml

Apply it in your ListView:

<shape android:shape="rectangle">
    <size android:height="15dp"/>  <!-- Adjust thickness -->
    <solid android:color="#D3D3D3"/>  <!-- Light gray -->
</shape>
