android:簡單包裝實現偽自定義DatePickerDialog和TimePickerDialog
之所以寫這個東西，是因為在我們的設計中需要給 日期選擇器加一個標題，一開始直接使用 原生的 DatePickerAlertDialog ，因為他繼承自 AlertDialog ,所以就直接 呼叫了 setTitle 方法，然而，醜的那叫一塌糊塗啊。所以，最後只好自己簡單包裝一下。
內容簡單，不做過多解釋，直接上程式碼。

3 總結：
以上內容就是完整程式碼，整體比較簡單。
- DatePicker 設定 為 Spinner 模式時這裡使用了
style="@android:style/Widget.DatePicker"- TimePicker 設定為 Spinner 模式時使用了
timePickerMode=spinner, 之所以不用 style ，是因為spinner 模式的style="@android:style/Widget.TimePicker"被系統 私有了，無法呼叫，系統對外提供的都是 MaterialDesign 模式的Style
最初是想將 DatePicker 和 TimePicker 包裝到同一個 AlertDialog 中，但是非常遺憾，TimePicker 和 DatePicker 底層用的是 NumberPicker ，寬度寫死了，導致 將 TimePicker 和 DatePicker 橫向放在同一個 AlertDialog 中時會導致超出寬度，部分內容無法展示。這種情況暫時沒想好怎麼解決，如果哪位大俠知道，煩請告知，謝謝!
