如何把ArrayList转化成一个String[]呢；
static   ArrayList <SelectItem>   selectProgramNameList   =   new   ArrayList <SelectItem> ()；
ArrayList中有数据，放到String[]a;中

------解决方案--------------------
String [] arr = new String[];
int i = 0;
for(String str : arrayList){
arr[i++] = str;
}


------解决方案--------------------
(String[])rBasicBean.getSelectProgramNameList().toArray()
------解决方案--------------------
(String[])selectProgramNameList.toArray()
------解决方案--------------------
String [] arr = new String[];
int i = 0;
for(String str : arrayList){
arr[i++] = str;
}


这样可行
