布局看起来很棒，但在移动设备中却不是。怎么克服！！！

尝试将每个视图分别连接到父视图，观看了一些教程来解决问题，但没有解决问题。我尝试将每个视图与父视图连接，但在横向模式下没有解决问题。

请注意，在您的回答和问题中，您都在视图​​上使用固定尺寸，这不会使您的屏幕响应所有屏幕尺寸（您将来会继续看到您的问题）。我同意您可以使用指南，但不要使用固定大小的指南，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，所以在图片中你看不到他）：

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）视图添加链，然后循环链（出现在当前视图底部的按钮）以更改它们之间的间隙。

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。祝你好运！！！ https://www.youtube.com/watch?v=hqEfshM5Vfw

希望对初学者有帮助
