当我读到数据库显示错误时这样。请回复我

1 个答案:

答案 0 :(得分：2)

重要的是...... 

... Caused by: java.lang.IllegalStateException: /data/data/com.example.search/databases/rlite.db SQLiteDatabase created and never closed

您可能在关闭数据库之前允许停止/退出您的活动。 （如果您没有在生命周期中实现所有（onXXX（）方法），就会发生这种情况。例如，如果您旋转设备，它们可能会被意外触发。

将db访问例程写为

db.open()
db.dosomething()
db.close()

或者确保在获得onSuspend（）时关闭数据库（我想......可能是其中之一）并在重新启动时重新打开它。

希望这有帮助

彼得
