• Method Detail

  • onCreate

    void onCreate()

    Called when your factory is first constructed. The same factory may be shared across multiple RemoteViewAdapters depending on the intent passed.

  • onDataSetChanged

    void onDataSetChanged()

    Called when notifyDataSetChanged() is triggered on the remote adapter. This allows a RemoteViewsFactory to respond to data changes by updating any internal references. Note: expensive tasks can be safely performed synchronously within this method. In the interim, the old data will be displayed within the widget.

    AppWidgetManager.notifyAppWidgetViewDataChanged(int[], int)

  • onDestroy

    void onDestroy()

    Called when the last RemoteViewsAdapter that is associated with this factory is unbound.

  • getCount

    int getCount()

    See Adapter.getCount()

    Returns:

    Count of items.

  • getViewAt

    RemoteViews getViewAt(int position)

    See Adapter.getView(int, android.view.View, android.view.ViewGroup). Note: expensive tasks can be safely performed synchronously within this method, and a loading view will be displayed in the interim. See getLoadingView().

    Parameters:

    position - The position of the item within the Factory's data set of the item whose view we want.

    Returns:

    A RemoteViews object corresponding to the data at the specified position.

  • getLoadingView

    RemoteViews getLoadingView()

    This allows for the use of a custom loading view which appears between the time that getViewAt(int) is called and returns. If null is returned, a default loading view will be used.

    Returns:

    The RemoteViews representing the desired loading view.

  • getViewTypeCount

    int getViewTypeCount()

    See Adapter.getViewTypeCount().

    Returns:

    The number of types of Views that will be returned by this factory.

  • getItemId

    long getItemId(int position)

    See Adapter.getItemId(int).

    Parameters:

    position - The position of the item within the data set whose row id we want.

    Returns:

    The id of the item at the specified position.

  • hasStableIds

    boolean hasStableIds()

    See Adapter.hasStableIds().

    Returns:

    True if the same id always refers to the same object.
