如标题所述，在编译时，控制台说：Failed to install ap.apk

但是 logcat 显示了这一点：

我评论了我所有的“retour”方法并删除了所有与此方法相关的android:onClick，它没有帮助......之前一切都很好......

有人可以帮忙吗？

先感谢您

IllegalStateException: Could not find a method retour(View)

我认为问题在于您（肯定）已经在 XML 中指定onClick了一个方法retour，但该方法在 Java 代码中不存在。

如果问题仍然存在，请尝试清理项目并关闭您的网络电话。
