Is it possible to change the style of an Android L TimePickerDialog?
提问by JDJ
I was testing my app on an Android L emulator, and I noticed that the TimePickerDialog has significantly changed to this:
我在 Android L 模拟器上测试我的应用程序，我注意到 TimePickerDialog 已显着更改为：
This doesn't fit with the theme of my app, and I wanted to know if it is possible to get the old TimePickerDialog style when running on Android L.
这不符合我的应用程序的主题，我想知道在 Android L 上运行时是否可以获取旧的 TimePickerDialog 样式。

You can use the TimePickerDialogconstructor with themeparameter to specify the theme.
您可以使用带参数的TimePickerDialog构造theme函数来指定主题。
TimePickerDialog(Context context,
int theme,
TimePickerDialog.OnTimeSetListener callBack,
int hourOfDay,
int minute,
boolean is24HourView)

Add android:timePickerMode="spinner"to the XML
将android:timePickerMode="spinner" 添加到 XML
<TimePicker
android:id="@+id/timePicker1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:timePickerMode="spinner">
</TimePicker>

You can choose between spinneror clockmodes. This attribute is only available from API level 21, before that the spinnermode was the only option available.
您可以在微调器或时钟模式之间进行选择。此属性仅在 API 级别 21 中可用，在此之前微调模式是唯一可用的选项。

If you want the AM / PM to be a picker instead of a button then I recommend you use the single parameter constructor with a ContextThemeWrapper:
如果您希望 AM / PM 成为选择器而不是按钮，那么我建议您使用带有 的单参数构造函数ContextThemeWrapper：
new TimePicker(new ContextThemeWrapper(getActivity(), android.R.style.Theme_Holo_Light_Dialog_NoActionBar));
If you pass the theme into the multiple parameter constructor then you'll end up with a rather ugly AM / PM button, and the colon will be missing between the hour and minute columns.
如果您将主题传递给多参数构造函数，那么您最终会得到一个相当丑陋的 AM / PM 按钮，并且小时和分钟列之间将缺少冒号。
new TimePicker(getActivity(), null, TimePickerDialog.THEME_HOLO_LIGHT);

As LordRaydenMK said, use the TimePickerDialogconstructor with themeparameter and provide this theme: android.R.style.CustomDatePickerDialog
正如 LordRaydenMK 所说，使用TimePickerDialog带theme参数的构造函数并提供这个主题：android.R.style.CustomDatePickerDialog
And in your Styles.xmldefine this:
在你Styles.xml定义这个：
<style name="CustomDatePickerDialog"
parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:dialogTheme">@style/MyDialogTheme</item>
<item name="android:timePickerStyle">@style/MyDatePicker</item>
</style>
<style name="MyDialogTheme"
parent="Theme.AppCompat.Light.Dialog">
<item name="android:timePickerStyle">@style/MyDatePicker</item>
</style>
<style name="MyDatePicker"
parent="@android:style/Widget.Material.Light.TimePicker">
<item name="android:timePickerMode">spinner</item>
</style>
