  • CursorLoader

    public CursorLoader(Context context)

    Creates an empty unspecified CursorLoader. You must follow this with calls to setUri(Uri), setSelection(String), etc to specify the query to perform.

  • CursorLoader

    public CursorLoader(Context context,
                Uri uri,
                String[] projection,
                String selection,
                String[] selectionArgs,
                String sortOrder)

    Creates a fully-specified CursorLoader. See ContentResolver.query() for documentation on the meaning of the parameters. These will be passed as-is to that call.

• Method Detail

  • loadInBackground

    public Cursor loadInBackground()

    Specified by:

    loadInBackground in class AsyncTaskLoader<Cursor>

  • deliverResult

    public void deliverResult(Cursor cursor)

    Description copied from class: Loader
    Sends the result of the load to the registered listener. Should only be called by subclasses. Must be called from the process's main thread.

    Overrides:

    deliverResult in class Loader<Cursor>

    Parameters:

    cursor - the result of the load

  • onStartLoading

    protected void onStartLoading()

    Starts an asynchronous load of the contacts list data. When the result is ready the callbacks will be called on the UI thread. If a previous load has been completed and is still valid the result may be passed to the callbacks immediately. Must be called from the UI thread

    Overrides:

    onStartLoading in class Loader<Cursor>

  • onStopLoading

    protected void onStopLoading()

    Must be called from the UI thread

    Overrides:

    onStopLoading in class Loader<Cursor>

  • onCanceled

    public void onCanceled(Cursor cursor)

    Description copied from class: AsyncTaskLoader
    Called if the task was canceled before it was completed. Gives the class a chance to properly dispose of the result.

    Overrides:

    onCanceled in class AsyncTaskLoader<Cursor>

  • onReset

    protected void onReset()

    Description copied from class: Loader
    Subclasses must implement this to take care of resetting their loader, as per Loader.reset(). This is not called by clients directly, but as a result of a call to Loader.reset(). This will always be called from the process's main thread.

    Overrides:

    onReset in class Loader<Cursor>
