NumberPicker Customization

Question

I am attempting to add several NumberPicker(s) to my app. I have managed to add the NumberPicker tags to my xml & give them basic functionality, but I cannot seem to find much info on how to modify the appearance. I have looked at the documentation at:

https://developer.android.com/reference/android/widget/NumberPicker
https://learn.microsoft.com/en-us/dotnet/api/android.widget.numberpicker?view=xamarin-android-sdk-12

But there is very little detail about how to use the properties related to the visual appearance. Are there any good tutorials or details about how to customize the visual appearance of NumberPicker? Thanks.

Hello,

In fact, the custom extensibility of the native Android control NumberPicker is poor.

The appearance of NumberPicker is only relevant to the theme, which is mainly designed from the point of view of appearance consistency.

If you want to customize its appearance, then you need to rewrite a NumberPicker control, or set the theme to achieve this, you could refer to the following code:

   android:theme="@android:style/Theme.NoTitleBar"
