最佳答案

我找到了我的问题的解决方案我在解析数据并将数据插入数据库时​​使用事务。但在这两者之间，我试图从数据库中获取一些值。所以像下面这样的层次结构

<transaction>
<Insert>
 <select>
<insert>
</transaction>

我正在尝试对数据库运行选择查询，而数据库处于事务中。其实这里有一个关于concurrent transaction的解决方案

SQL 命令“BEGIN TRANSACTION”(TRANSACTION 关键字是可选的)用于使SQLite 退出自动提交模式。请注意，BEGIN 命令不会获取数据库上的任何锁。在 BEGIN 命令之后，当执行第一个 SELECT 语句时将获取一个 SHARED 锁。当执行第一个 INSERT、UPDATE 或 DELETE 语句时，将获取一个 RESERVED 锁。在内存缓存填满并且必须溢出到磁盘或事务提交之前，不会获取 EXCLUSIVE 锁。这样，系统延迟阻止对文件文件的读取访问，直到最后一刻。

我只是在数据库处于事务中时从代码中删除了选择查询行

编辑

还有另一种解决方案是将锁定启用设置为 false，如

mDb.setLockingEnabled(false);
