    ListAdapter bookAdapter = new SimpleCursorAdapter(this,R.layout.booklist,cursor,from,to);

提示：The constructor SimpleCursorAdapter(Context, int, Cursor, String[], int[]) is deprecated

API 16给出的解析：
@Deprecated
public SimpleCursorAdapter(Context context,
                              int layout,
                              Cursor c,
                              String[] from,
                              int[] to)

Deprecated. This option is discouraged, as it results in Cursor queries being performed on the application's UI thread
 and thus can cause poor responsiveness or even Application Not Responding errors. 
As an alternative, use LoaderManager with a CursorLoader.
Constructor the enables auto-requery.

public SimpleCursorAdapter(Context context,
