Known Indirect Subclasses
|
An extension of SpinnerAdapter that is capable of inflating drop-down views against a different theme than normal views.
Classes that implement this interface should use the theme provided to setDropDownViewTheme(android.content.res.Resources.Theme) when creating views in SpinnerAdapter#getDropDownView(int, View, ViewGroup).
Summary
| Inherited functions |
From class Adapter
Array<CharSequence!>? |
getAutofillOptions()
Gets a string representation of the adapter data that can help android.service.autofill.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 android.view.ViewStructure#setDataIsSensitive(boolean) for more info.
|
Int |
getCount()
How many items are in the data set represented by this Adapter.
|
Any! |
getItem(position: Int)
Get the data item associated with the specified position in the data set.
|
Long |
getItemId(position: Int)
Get the row id associated with the specified position in the list.
|
Int |
getItemViewType(position: Int)
Get the type of View that will be created by getView for the specified item.
|
View! |
getView(position: Int, convertView: View!, parent: ViewGroup!)
Get a View that displays the data at the specified position in the data set. You can either create a View manually or inflate it from an XML layout file. When the View is inflated, the parent View (GridView, ListView...) will apply default layout parameters unless you use android.view.LayoutInflater#inflate(int, android.view.ViewGroup, boolean) to specify a root view and to prevent attachment to the root.
|
Int |
getViewTypeCount()
Returns the number of types of Views that will be created by getView. Each type represents a set of views that can be converted in getView. If the adapter always returns the same type of View for all items, this method should return 1.
This method will only be called when the adapter is set on the AdapterView.

Boolean |
hasStableIds()
Indicates whether the item ids are stable across changes to the underlying data.
|
