CursorAdapter

public static final int FLAG_AUTO_REQUERY = 1

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

public static final int FLAG_REGISTER_CONTENT_OBSERVER = 2

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 CursorAdapter(Context context, Cursor c)

Constructor that always enables auto-requery.

public CursorAdapter(Context context, Cursor c, boolean autoRequery)

Constructor that allows control over auto-requery. It is recommended you not use this, but instead CursorAdapter. When using this constructor, FLAG_REGISTER_CONTENT_OBSERVER will always be set.

public CursorAdapter(Context context, Cursor c, int flags)

Recommended constructor.

public abstract void bindView(View view, Context context, Cursor cursor)

Bind an existing view to the data pointed to by cursor

public void changeCursor(Cursor cursor)

Change the underlying cursor to a new cursor. If there is an existing cursor it will be closed.

public 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.

public Cursor getCursor()

Returns the cursor.

public FilterQueryProvider getFilterQueryProvider()

Returns the query filter provider used for filtering. When the provider is null, no filtering occurs.

public View newDropDownView(Context context, Cursor cursor, ViewGroup parent)

Makes a new drop down view to hold the data pointed to by cursor.

public abstract View newView(Context context, Cursor cursor, ViewGroup parent)

Makes a new view to hold the data pointed to by cursor.

public Cursor runQueryOnBackgroundThread(CharSequence constraint)

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 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.

public void setFilterQueryProvider(FilterQueryProvider filterQueryProvider)

Sets the query filter provider used to filter the current Cursor. The provider's runQuery method is invoked when filtering is requested by a client of this adapter.

public Cursor swapCursor(Cursor newCursor)

Swap in a new Cursor, returning the old Cursor. Unlike changeCursor, the returned old Cursor is not closed.

protected void 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.
