BaseAdapter<T> Class

Definition

Common base class of common implementation for an Adapter that can be used in both ListView (by implementing the specialized IListAdapter interface) and Spinner (by implementing the specialized ISpinnerAdapter interface).

public abstract class BaseAdapter<T> : Android.Widget.BaseAdapter
[<Android.Runtime.Register("android/widget/BaseAdapter", DoNotGenerateAcw=true)>]
type BaseAdapter<'T> = class
    inherit BaseAdapter

Clone()

Creates and returns a copy of this object.

(Inherited from Object)
GetAutofillOptions()

Gets a string representation of the adapter data that can help AutofillService autofill the view backed by the adapter. It should only be set (i.e., non- null if the values do not represent PII (Personally Identifiable Information - sensitive data such as email addresses, credit card numbers, passwords, etc...). For example, it's ok to return a list of month names, but not a list of usernames. A good rule of thumb is that if the adapter data comes from static resources, such data is not PII - see ViewStructure.setDataIsSensitive(boolean) for more info.
