日期选择器，单选框，多选框（自定义title）对话框

**

1. 单选、多选对话框：可通过调用setSingleChoiceItems()或setMultiChoiceItems()设置对话框。
   final String items[] = {“男”, “女”, “未知性别”, “其他”};
   final AlertDialog.Builder radioBuilder = new AlertDialog.Builder(this);
   final AlertDialog.Builder checkBuilder = new AlertDialog.Builder(this);
   final boolean isRadio[] = {false,false,false,false,false};
   radioBuilder .setSingleChoiceItems(数据资源，默认选择按钮，监听事件);
   checkBuilder.setMultiChoiceItems(数据资源，boolean类型数组，监听事件)

2. 单选对话框
   可以自己设置在xml文件中设置样式
   View vew = LayoutInflater.from(this).inflate(R.layout.layout的名字, null);
   final AlertDialog.Builder radioBuilder = new AlertDialog.Builder(this);
   radioBuilder.setView(view);//设置自定义布局
   通过获取RadioGroup控件设置监听事件。
