Remove lines in a ListPicker or hide them using styles

Question

Is there any way to lose the lines on a ListPicker? See my image.

Answer 1

For Android I know,

go here app\App_Resources\Android\src\main\res\values\styles.xml then under name="AppThemeBase" add

<item name="colorControlNormal">@color/transparent</item>

here is the color.xml

<color name="transparent">@android:color/transparent</color>

That's all, For ios also I hope same thing will be there.
