Java 数据库操作需要一个生命周期来处理
好吧，这更像是速度问题。问题是我从不同的来源获取了三个字段，比如Contacts、Facebook和Google plus。这三个字段是日期、姓名和联系人图像URi。逻辑是这样的，每个源都写入一个文件，联系人——文件，Facebook——附加到同一个文件，Google Plus——附加到同一个文件。此操作非常快，需要正常时间执行。这将创建我的原始数据源。然后从这个文件中，我分别获取每个记录（包含三个字段的行），并进行一些计算，并将与每个记录相关的数据写入三个不同的数据库表中。虽然这在四核手机上运行得很快，但在双核手机上的处理速度太慢。在双核上处理150条记录大约需要10分钟，在四核上处理150条记录需要4分钟。我困惑于如何提高速度？我是否应该放弃将文件作为原始数据源的想法，转而切换到数据库表？最快的是什么 代码如下：Java 数据库操作需要一个生命周期来处理,java,android,file,sqlite,Java,Android,File,Sqlite,好吧，这更像是速度问题。问题是我从不同的来源获取了三个字段，比如Contacts、Facebook和Google plus。这三个字段是日期、姓名和联系人图像URi。逻辑是这样的，每个源都写入一个文件，联系人——文件，Facebook——附加到同一个文件，Google Plus——附加到同一个文件。此操作非常快，需要正常时间执行。这将创建我的原始数据源。然后从这个文件中，我分别获取每个记录（包含三个字段的行），并进行一些计算，并将与每个记录相关的数据写入三个不同的数据库表中。虽然这在四核手机上运
