之所以写这个东西，是因为在我们的设计中需要给 日期选择器加一个标题，一开始直接使用 原生的 DatePickerAlertDialog ，因为他继承自 AlertDialog ,所以就直接 调用了 setTitle 方法，然而，丑的那叫一塌糊涂啊。所以，最后只好自己简单包装一下。
内容简单，不做过多解释，直接上代码。

3 总结：
以上内容就是完整代码，整体比较简单。
- DatePicker 设置 为 Spinner 模式时这里使用了
style="@android:style/Widget.DatePicker"- TimePicker 设置为 Spinner 模式时使用了
timePickerMode=spinner, 之所以不用 style ，是因为spinner 模式的style="@android:style/Widget.TimePicker"被系统 私有了，无法调用，系统对外提供的都是 MaterialDesign 模式的Style
最初是想将 DatePicker 和 TimePicker 包装到同一个 AlertDialog 中，但是非常遗憾，TimePicker 和 DatePicker 底层用的是 NumberPicker ，宽度写死了，导致 将 TimePicker 和 DatePicker 横向放在同一个 AlertDialog 中时会导致超出宽度，部分内容无法展示。这种情况暂时没想好怎么解决，如果哪位大侠知道，烦请告知，谢谢!
