the rest of problem

1. in ShopList UI, didn't bind spinner UI. To solve this problem, if is distance shoplist context, need distance array, category array and order array. if is district shoplist context, need district array, category array and order array.
2. in ShopDetail UI, didn't bind head button UI. I want change this button to tabHost UI.
3. The phone button didn't bind function In android system, if you want dial tele number and ext tele number together, you just need add "," between them. I test this in the real phone, don't know if this can work in code.
