How to remain the "Select One" string when adding Items in Spinner

I have a question that, I have two spinners, both spinners are filled by data after JSON parsing, presently when we call that particular Activity (Which opens after Parsing, in which both Spinners are held), all data are shown in first Spinner and in second spinner according to First Spinner's Selection but we want that when we call that Activity it firstly shows Select in all spinners, and when we click on them then it shows its values. How can we acheive that. Please help me out about this problem.

Thanks in advance.
