requery() 更新 Cursor，而不是 CursorAdapter.正如你所说，它已被弃用，它的替代品是:

requery() updates a Cursor, not a CursorAdapter. As you say, it has been deprecated, and its replacement is:

oldCursor = myCursorAdapter.swapCursor(newCursor); // hands you back oldCursor

或:

myCursorAdapter.changeCursor(newCursor); // automatically closes old Cursor

myCursorAdapter.notifyDataSetChanged() 通知 ListView 数据集已经改变，它应该自己刷新

myCursorAdapter.notifyDataSetChanged() notifies the ListView that the data set has changed, and it should refresh itself
