      {
      String currlst = persons[i];

You are missing the part where you declare "currlstArr". You are setting the value of currlstArr inside the foreach, so, if t< 0 you have nothing set, otherwise, you have the value of .split. Your use of setAdapter itself looks fine. Try

currlstArr = new String[] { "Android", "iPhone", "WindowsMobile",
        "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
        "Linux", "OS/2", "Ubuntu", "Windows7", "Max OS X", "Linux",
        "OS/2", "Ubuntu", "Windows7", "Max OS X", "Linux", "OS/2",
        "Android", "iPhone", "WindowsMobile" };
