SpinnerAdapter
interface SpinnerAdapter : Adapter
Known Indirect Subclasses
|
Extended Adapter
that is the bridge between a android.widget.Spinner
and its data. A spinner adapter allows to define two different views: one that shows the data in the spinner itself and one that shows the data in the drop down list when the spinner is pressed.
Summary
Public methods |
abstract View! |
Gets a android.view.View that displays in the drop down popup the data at the specified position in the data set.
|
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.
|
Boolean |
isEmpty()
|
Unit |
registerDataSetObserver(observer: DataSetObserver!)
Register an observer that is called when changes happen to the data used by this adapter.
|
Unit |
unregisterDataSetObserver(observer: DataSetObserver!)
Unregister an observer that has previously been registered with this adapter via registerDataSetObserver .
|
|
Public methods
getDropDownView
abstract fun getDropDownView(
position: Int,
convertView: View!,
parent: ViewGroup!
): View!
Gets a android.view.View
that displays in the drop down popup the data at the specified position in the data set.
Parameters |
position |
Int: index of the item whose view we want. |
convertView |
View!: the old view to reuse, if possible. Note: You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view. |
parent |
ViewGroup!: the parent that this view will eventually be attached to |
