android - Android：片段不适合片段容器
问题描述
我在 MainActivity 中有一个片段容器视图。我有一个寄存器片段。在寄存器片段内，我有约束布局。当我在手机中启动应用程序时，寄存器片段不适合片段容器。我怎么解决这个问题？

</FrameLayout>解决方案
注册片段非常适合，它根据片段容器中可用的区域进行拟合。由于该区域是有限的，所以这就是为什么对你来说它似乎被切断了。
这是您可以执行的操作，您可以在 RegisterFragment 中添加 ScrollView，我不知道您为什么使用 FrameLayout，但据我所知，您可以用 ScrollView 替换它。除此之外，您需要为最后一个元素提供底部约束和底部的边距。这就是它的样子。
