Java 为什么赢了'；在Android Studio中找到这些带ButterKnife的文本视图不是吗？

我的代码有问题吗？由于某些原因，我无法从我的

activity\u main.xml

获取文本视图，以链接到我的

MainActivity.java

文件

这是我的密码

它总是显示为红色，如果我尝试运行它，它会得到一个无法解析的符号

根据要求，这里是gradle文件！谢谢

您忘记在

onCreate

方法中调用

ButterKnife.bind（this）

。

---

如果您不这样做，butterknife将不会插入您的视图，您将遇到问题。

我已经这样做了，但无论我如何做或使用什么，仍然无法识别它们？我也试着重建。请把你的毕业档案贴在这里。顺便说一句，你有打字错误。应该是

ButterKnife.bind（this）

而不是小写的

k

。谢谢你的提醒，编辑它吧！如果有帮助，请在回答时打勾！
