Iterator对对象遍历

 //实例对象tables

 List<Table> tables = new TableManager(getApplicationContext()).queryTables();
  spinnerValue = new String[tables.size()+1];
   spinnerValue[0]=table_no;
//Iterator遍历 tables

 int i = 1;
   for (Iterator<Table> iterator = tables.iterator(); iterator.hasNext(); i++) {
    spinnerValue[i] = ((Table) iterator.next()).getRemark();//getNum().toString()
   }
