我正在开发一款供用户分享图书的应用。为了实现这一点，我从用户那里得到了关于这本书的不同数据。问题是，所有 EditText 的水平自动滚动都在工作，直到显示并关闭对话框。一旦 fragment 上的对话框被取消，EditText 在此布局上的水平自动滚动将不起作用。
我补充说:
android:focusable="true"
android:focusableInTouchMode="true"
到 edittext 的父布局但不起作用。
同时为了确保启用自动滚动，我添加了:
android:scrollHorizontally="true"
但以上都没有帮助。
这是 fragment 布局的 XML 代码。

在上图中，有 EditTexts Name Of Book 和 Name of Author。在显示对话之前，它们都像魅力一样工作。写东西时，光标会自动滚动到末尾。显示和关闭对话框后，它们都无法正常工作，并且光标停留在 EditText 的末尾，但仍在隐藏部分继续写入字符。
在这个 UI 中，由于问题而无法看到，但我已经写了。 玫瑰是红色的，紫罗兰是蓝色的，Stackoverflow 我爱你
但只有玫瑰是红色的，紫罗兰是蓝色的，Stac可以看到。
请帮我解决这个问题。提前致谢。
最佳答案
作为一种解决方案，我不知道根本原因，但是一旦我从我的项目中删除了 Butterknife 库，问题就解决了。
关于java - 显示对话框后 EditText 自动滚动不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57452047/
