HeaderViewListAdapter


open class HeaderViewListAdapter : WrapperListAdapter, Filterable
kotlin.Any
   ↳ android.widget.HeaderViewListAdapter

ListAdapter used when a ListView has header views. This ListAdapter wraps another one and also keeps track of the header views and their associated data objects.

This is intended as a base class; you will probably not need to use this class directly in your own code.

    footerViewInfos: ArrayList<ListView.FixedViewInfo!>!,
    adapter: ListAdapter!)

Public methods

areAllItemsEnabled

Added in API level 1
open fun areAllItemsEnabled(): Boolean
Return
Boolean True if all items are enabled, false otherwise.

getCount

Added in API level 1
open fun getCount(): Int
Return
Int Count of items.

getFilter

Added in API level 1
open fun getFilter(): Filter!
Return
Filter! a filter used to constrain data

getFootersCount

Added in API level 1
open fun getFootersCount(): Int

getHeadersCount

Added in API level 1
open fun getHeadersCount(): Int

getItem

Added in API level 1
open fun getItem(position: Int): Any!
Parameters
position Int: Position of the item whose data we want within the adapter's data set.
Return
Any! The data at the specified position.

getItemId

Added in API level 1
open fun getItemId(position: Int): Long
Parameters
position Int: The position of the item within the adapter's data set whose row id we want.
Return
Long The id of the item at the specified position.

getItemViewType

Added in API level 1
open fun getItemViewType(position: Int): Int
Parameters
position Int: The position of the item within the adapter's data set whose view type we want.
Return
Int An integer representing the type of View. Two views should share the same type if one can be converted to the other in getView. Note: Integers must be in the range 0 to getViewTypeCount - 1. IGNORE_ITEM_VIEW_TYPE can also be returned.

getView

Added in API level 1
open fun getView(
    position: Int,
    convertView: View!,
    parent: ViewGroup!
): View!
Parameters
position Int: The position of the item within the adapter's data set 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. Heterogeneous lists can specify their number of view types, so that this View is always of the right type (see getViewTypeCount() and getItemViewType(int)).
parent ViewGroup!: The parent that this view will eventually be attached to
Return
View! A View corresponding to the data at the specified position.

getViewTypeCount

Added in API level 1
open fun getViewTypeCount(): Int
Return
Int The number of types of Views that will be created by this adapter

getWrappedAdapter

Added in API level 1
open fun getWrappedAdapter(): ListAdapter!
Return
ListAdapter! The android.widget.ListAdapter wrapped by this adapter.

hasStableIds

Added in API level 1
open fun hasStableIds(): Boolean
Return
Boolean True if the same id always refers to the same object.

isEmpty

Added in API level 1
open fun isEmpty(): Boolean
Return
Boolean true if this adapter doesn't contain any data. This is used to determine whether the empty view should be displayed. A typical implementation will return getCount() == 0 but since getCount() includes the headers and footers, specialized adapters might want a different behavior.

isEnabled

Added in API level 1
open fun isEnabled(position: Int): Boolean
Parameters
position Int: Index of the item
Return
Boolean True if the item is not a separator

registerDataSetObserver

Added in API level 1
open fun registerDataSetObserver(observer: DataSetObserver!): Unit
Parameters
observer DataSetObserver!: the object that gets notified when the data set changes.

removeFooter

Added in API level 1
open fun removeFooter(v: View!): Boolean

removeHeader

Added in API level 1
open fun removeHeader(v: View!): Boolean

unregisterDataSetObserver

Added in API level 1
open fun unregisterDataSetObserver(observer: DataSetObserver!): Unit
Parameters
observer DataSetObserver!: the object to unregister.
