【问题讨论】：

标签： android cursor finalizer

【解决方案1】：

在 com.meme.whatami.elhgsdatabase.getAllInfo(elhgsdatabase.java:157) 调用“查询”之后：

cursor.close();

【讨论】：

public Cursor getAllTitles() { return db.query(DATABASE_TABLE, new String[] { KEY_ROWID, KEY_bookNO, KEY_TIMEFROM, KEY_TIMETO, KEY_LINK, KEY_bookLINK, KEY_bookTIME, KEY_C1, KEY_C2, KEY_C3 }, null, null ，空，空，空）； }
嗯，您正在返回一个您正在其他地方使用的游标。使用完之后（在 getAllTiles 调用之后）然后关闭它。
