如何在CursorAdapter的情况下使用了更新的ListView？ [英] How to update ListView in case of CursorAdapter usage?

问题描述

我问那的原因是因为重新查询（）是pcated德$ P $。什么是现在刷新最好的办法你的的ListView ？

The reason I'm asking that is because requery() is deprecated. What is the best way now to refresh your ListView?

推荐答案

重新查询（）更新一个光标，不是的CursorAdapter 。正如你所说，它已经去precated，其更换为：

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（）通知的ListView ，该数据集已经变了，它应该自动刷新

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