【中文标题】将 Yandex 翻译器添加到 Fragment 会导致“应用程序崩溃”【英文标题】：Adding Yandex Translator to Fragment leads to "App Crashes" 【发布时间】：2018-05-02 13:12:07 【问题描述】：我在我的应用程序中使用 Yandex Translator，如果我使用 Activity 效果很好，但是当我将它添加到 fragment 时，应用程序在启动前崩溃。 代码中也没有显示错误，就像一切都很好，可能是什么问题： 我在这里寻找了类似的答案，但我一无所获，在使用片段之前没有人遇到过这个问题。
这是片段的代码：

【问题讨论】：
使用 LogCat 检查与您的崩溃相关的 Java 堆栈跟踪：***.com/questions/23353173/… 这里是 logcat，我不明白究竟是什么让应用程序崩溃 【参考方案1】：请从onViewCreated() 而非onCreateView() 致电setupInteraction()。您正在尝试使用getView()，在onCreateView() 返回之前将无法使用。

你能告诉我在哪里编辑，因为我不擅长编程；以上是关于将 Yandex 翻译器添加到 Fragment 会导致“应用程序崩溃”的主要内容，如果未能解决你的问题，请参考以下文章
