android:简单包装实现伪自定义DatePickerDial

2017-09-04  本文已影响416人  CnPeng

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!
