android - 尝试在空对象引用上调用接口方法“boolean android.view.inputmethod.InputConnection.finishComposingText()”-Android Kotlin

Question

当我单击工具栏后退按钮（如 gif 所示）时，发生错误：Attempt to invoke interface method 'boolean android.view.inputmethod.InputConnection.finishComposingText()' on a null object reference。我认为这是由于专注于 EditText

您的代码没有任何问题。尝试清理您的构建缓存。见下图

然后重建你的项目

您还应该尝试删除项目目录中的 .gradle 文件夹。
