问题描述

使用constrainLayout时支持不同屏幕尺寸的最佳方法是什么?

What is the best way of supporting different screen sizes when using a constrainLayout?

问题:

当我将设备更改为屏幕尺寸小于4.7的任何设备时,底部的按钮通常会位于屏幕底部下方.我已经固定了按钮,并认为所有视图都将缩小以容纳其余部分.

When I change the device to any device with a screen size of less than 4.7" the button at the bottom tends to go below the bottom edge of the screen. I have anchored the button and I thought that all the views will be shrunk to accommodate the rest.

我的代码:

推荐答案

不.您必须对其进行设计,以使其supports a certain minimum screen size.而且,这不仅是ConstraintLayout所特有的,它还会在RelativeLayout或任何其他布局中发生.

No. You have to design it so that it supports a certain minimum screen size.And this is not specific only to ConstraintLayout, it will happen with RelativeLayout or any other layout.

请参见支持不同的屏幕尺寸.

您可以使用 ScrollView ,当内容超过屏幕大小时,内容将滚动.

In your case you can use a ScrollView, so that the content will scroll when it exceed the size of the screen.
