Java rawquery选择作为数据库输入

我想知道如何获取所选查询的值

Cursor data = dbObject.rawQuery("SELECT _id FROM COMAPNY WHERE _id LIKE ?",
                 new String[] { "%" + val2 + "%" });

作为sqlite数据库输入。我想选择数字val2，然后将该数字放入handle.KEY_ID2列。有可能吗？怎么做

活动1

至于现在，我必须输入KEY_ID2，但我想要的是。。当用户单击ACTIVITY1列表时。。。它将行id作为val1发送&我希望在ACTIVITY2按钮上输入该值单击

没有直接的方法。您需要：

对数据库进行查询以获取光标， 将光标移动到第一个元素， 从游标中获取字符串/Int/任何内容， 使用Insert命令插入此值。 但我看到了一个更基本的问题：数据库布局。它不应该依赖于冗余保存的数据

请查看您的数据库，并检查是否可以使用关系在两个值之间建立连接。

COMAPNY？你确定它拼写正确吗？是的，我已经为你的信息添加了完整的代码，我知道你上面说了什么，但是我很难为它实现代码。如果你能帮我的话，我会很高兴的。不要发布你的全部代码。张贴您遇到问题的部件。
