Question

布局看起来很棒，但在Mobile中却没有。如何克服它！

试图将每个视图分别与父视图连接，观看了一些教程来解决该问题，但并没有解决问题。我尝试将每个视图与父视图连接，但没有以横向模式解决该问题。

请注意，在您的回答和问题中，您都使用固定大小的视图，这不会使您的屏幕对所有屏幕大小都做出响应（以后您会继续看到问题）。我同意您可以使用准则，但不要使用固定大小的准则，请像这样使用它们：

它看起来像这样（右上角的视图在那里但没有背景，所以在图片中您不会注意到他）：

Answer 2

使用水平指南将视图/按钮限制在特定区域，并通过选择每个水平（从左到右）视图然后添加链链，然后循环链（出现一个按钮在当前视图的底部）以更改两者之间的差距。

访问官方网站了解更多 https://developer.android.com/training/constraint-layout#constrain-chain

您也可以按照本教程进行操作。祝好运！！！ https://www.youtube.com/watch?v=hqEfshM5Vfw
