【问题描述】：

我仍然习惯于查看 logcat。我正在创建一个联系人应用程序来学习 android 开发，当我尝试加载此联系人信息时出现错误。如果可以的话，请解释一下这个 logcat，这样我就有机会更好地理解如何阅读它们。它正在尝试检索联系人 ID = 3 的信息。在此先感谢

【问题讨论】：

根据 logcat no such column: contact_id1

进行一些更改。更新了代码并发布了新的 logcat

【参考方案1】：

根据logcat，错误是：no such column: contact_id1

这是因为您忘记了这一行中的=：

ContactsContract.Data.CONTACT_ID + contactId

这给出了contact_id1 而不是contact_id = 1。应该是：

ContactsContract.Data.CONTACT_ID + " = " + contactId

【讨论】：

谢谢你。更改后，我收到另一个错误。编辑了我原来的帖子。如果/当你有机会时，请看看。

很高兴它对您有所帮助，但如果您有其他问题，您应该发布另一个问题（我不知道答案，抱歉）。

它发生了。感谢您的帮助
