.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();我正在运行 Android Studio 3.2 Canary 和 28 的目标 sdk。

您可以使用它来应用 Material 按钮样式:

 <style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

    <item name="android:buttonBarPositiveButtonStyle">@style/Widget.MaterialComponents.Button</item>
    <item name="android:buttonBarNegativeButtonStyle">@style/Widget.MaterialComponents.Button.TextButton</item>
    <item name="android:buttonBarNeutralButtonStyle">@style/Widget.MaterialComponents.Button</item>
</style>

结果:materialDatePicker
