Select option is showing in spinner's popped List
<p>I have a problem that I have two different spinners, data comes from json parsing in both of Spinners, When a item is selected from first spinner then second spinner gets filled by data but when nothing is selected in first spinner, it displays only Select option. But when user want to select other item from first spinner List also shows Select option which is not required. Please suggest me how to do that?</p>

<p>Thanks in advance.</p>
