| ↳ | 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.

Indicates whether all the items in this adapter are enabled. If the value returned by this method changes over time, there is no guarantee it will take effect. If true, it means all items are selectable and clickable (there is no separator.)
How many items are in the data set represented by this Adapter.
Returns a filter that can be used to constrain data with a filtering pattern.
This method is usually implemented by Adapter
classes.
Get the data item associated with the specified position in the data set.
| position | Position of the item whose data we want within the adapter's data set. |
|---|
Get the row id associated with the specified position in the list.
| position | The position of the item within the adapter's data set whose row id we want. |
|---|
Get the type of View that will be created by getView(int, View, ViewGroup) for the specified item.
| position | The position of the item within the adapter's data set whose view type we want. |
|---|
getView(int, View, ViewGroup). Note: Integers must be in the
range 0 to getViewTypeCount() - 1. IGNORE_ITEM_VIEW_TYPE can
also be returned.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
inflate(int, android.view.ViewGroup, boolean)
to specify a root view and to prevent attachment to the root.
| position | The position of the item within the adapter's data set of the item whose view we want. |
|---|---|
| convertView | 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 | The parent that this view will eventually be attached to |
Returns the number of types of Views that will be created by
getView(int, View, ViewGroup). Each type represents a set of views that can be
converted in getView(int, View, ViewGroup). 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 when the adapter is set on the
the AdapterView.
Returns the adapter wrapped by this list adapter.
ListAdapter wrapped by this adapter.
Indicates whether the item ids are stable across changes to the underlying data.
Returns true if the item at the specified position is not a separator.
(A separator is a non-selectable, non-clickable item).
The result is unspecified if position is invalid. An ArrayIndexOutOfBoundsException
should be thrown in that case for fast failure.
| position | Index of the item |

Register an observer that is called when changes happen to the data used by this adapter.
| observer | the object that gets notified when the data set changes. |

Unregister an observer that has previously been registered with this
adapter via registerDataSetObserver(DataSetObserver).
| observer | the object to unregister. |
