SimpleCursorAdapter

An easy adapter to map columns from a cursor to TextViews or ImageViews defined in an XML file.

An easy adapter that creates views defined in an XML file. You can specify the XML file that defines the appearance of the views.

Summary

Inherited constants

From class CursorAdapter

Int

FLAG_AUTO_REQUERY

If set the adapter will call requery() on the cursor whenever a content change notification is delivered. Implies FLAG_REGISTER_CONTENT_OBSERVER.

Int

FLAG_REGISTER_CONTENT_OBSERVER

If set the adapter will register a content observer on the cursor and will call onContentChanged() when a notification comes in. Be careful when using this flag: you will need to unset the current Cursor from the adapter to avoid leaks due to its registered observers. This flag is not needed when using a CursorAdapter with a android.content.CursorLoader.

Public constructors
`ResourceCursorAdapter(context: Context!, layout: Int, c: Cursor!)` Constructor the enables auto-requery.
`ResourceCursorAdapter(context: Context!, layout: Int, c: Cursor!, autoRequery: Boolean)` Constructor with default behavior as per `CursorAdapter#CursorAdapter(Context, Cursor, boolean)`; it is recommended you not use this, but instead `ResourceCursorAdapter(android.content.Context,int,android.database.Cursor,int)`.
`ResourceCursorAdapter(context: Context!, layout: Int, c: Cursor!, flags: Int)` Standard constructor.

Public methods
open View!	`newDropDownView(context: Context!, cursor: Cursor!, parent: ViewGroup!)`
open View!	`newView(context: Context!, cursor: Cursor!, parent: ViewGroup!)` Inflates view(s) from the specified XML file.
open Unit	`setDropDownViewResource(dropDownLayout: Int)` Sets the layout resource of the drop down views.
open Unit	`setDropDownViewTheme(theme: Resources.Theme?)` Sets the `android.content.res.Resources.Theme` against which drop-down views are inflated.
open Unit	`setViewResource(layout: Int)` Sets the layout resource of the item views.

Inherited functions

From class BaseAdapter

`Boolean`	`areAllItemsEnabled()`
`Array<CharSequence!>?`	`getAutofillOptions()`
`Int`	`getItemViewType(position: Int)`
`Int`	`getViewTypeCount()`
`Boolean`	`isEmpty()`
`Boolean`	`isEnabled(position: Int)`
`Unit`	`notifyDataSetChanged()` Notifies the attached observers that the underlying data has been changed and any View reflecting the data set should refresh itself.
`Unit`	`notifyDataSetInvalidated()` Notifies the attached observers that the underlying data is no longer valid or available. Once invoked this adapter is no longer valid and should not report further data set changes.
`Unit`	`registerDataSetObserver(observer: DataSetObserver!)`
`Unit`	`setAutofillOptions(vararg options: CharSequence!)` Sets the value returned by `getAutofillOptions()`
`Unit`	`unregisterDataSetObserver(observer: DataSetObserver!)`

From class CursorAdapter

`Unit`	`bindView(view: View!, context: Context!, cursor: Cursor!)` Bind an existing view to the data pointed to by cursor
`Unit`	`changeCursor(cursor: Cursor!)` Change the underlying cursor to a new cursor. If there is an existing cursor it will be closed.
`CharSequence!`	`convertToString(cursor: Cursor!)` Converts the cursor into a CharSequence. Subclasses should override this method to convert their results. The default implementation returns an empty String for null values or the default String representation of the value.
`Int`	`getCount()`
`Cursor!`	`getCursor()` Returns the cursor.
`View!`	`getDropDownView(position: Int, convertView: View!, parent: ViewGroup!)`
`Resources.Theme?`	`getDropDownViewTheme()`
`Filter!`	`getFilter()`
`FilterQueryProvider!`	`getFilterQueryProvider()` Returns the query filter provider used for filtering. When the provider is null, no filtering occurs.
`Any!`	`getItem(position: Int)`
`Long`	`getItemId(position: Int)`
`View!`	`getView(position: Int, convertView: View!, parent: ViewGroup!)`
`Boolean`	`hasStableIds()`
`Unit`	`init(context: Context!, c: Cursor!, autoRequery: Boolean)`
`Unit`	`onContentChanged()` Called when the `ContentObserver` on the cursor receives a change notification. The default implementation provides the auto-requery logic, but may be overridden by sub classes.
`Cursor!`	`runQueryOnBackgroundThread(constraint: CharSequence!)` Runs a query with the specified constraint. This query is requested by the filter attached to this adapter. The query is provided by a `android.widget.FilterQueryProvider`. If no provider is specified, the current cursor is not filtered and returned. After this method returns the resulting cursor is passed to `changeCursor(android.database.Cursor)` and the previous cursor is closed. This method is always executed on a background thread, not on the application's main thread (or UI thread.) Contract: when constraint is null or empty, the original results, prior to any filtering, must be returned. This method may take several seconds to complete, so it should only be called from a worker thread.
`Unit`	`setFilterQueryProvider(filterQueryProvider: FilterQueryProvider!)` Sets the query filter provider used to filter the current Cursor. The provider's `android.widget.FilterQueryProvider#runQuery(CharSequence)` method is invoked when filtering is requested by a client of this adapter.
`Cursor!`	`swapCursor(newCursor: Cursor!)` Swap in a new Cursor, returning the old Cursor. Unlike `changeCursor(android.database.Cursor)`, the returned old Cursor is not closed.
