列表对话框的单选模式：

 //单选模式
//        listDialog.setSingleSelectItems(new String[]{"第1个选项","第2个选项"},1);//单选
//        listDialog.setOnSingleSelectListener(new IDialog.ClickedListener() {

//                showToast(context,"单击了第"+(i+1)+"个选项");
//            }
//        });

多选模式：

 //多选模式
        listDialog.setMultiSelectItems(new String[]{"第1个选项","第2个选项"},new boolean[]{false,false});//多选
        listDialog.setOnMultiSelectListener(new IDialog.CheckBoxClickedListener() {
