通過AlertDialog.Builder類的setSingleChoiceItems方法可以創建帶單按鈕的列表：方法如下： 1、從資源文件中裝載數據： public Builder setSingleChoiceItems(int itemsId, int checkedItem, final OnClickListener listener) 2、從數據集中裝載數據 public Builder setSingleChoiceItems(Cursor cursor, int checkedItem, String labelColumn, final OnClickListener listener) 3、從字符串數組中裝載數據 public Builder setSingleChoiceItems(CharSequence[] items, int checkedItem, final OnClickListener listener) 4、從ListAdapter對象中裝載數據 public Builder setSingleChoiceItems(ListAdapter adpater, int checkedItem, final OnClickListener listener)
