sw600dp 和 w600dp 的区别? [英] Difference between sw600dp and w600dp?

问题描述

请简单说明swdp和wdp的区别.我研究了有关屏幕尺寸的完整文档，但对这两个限定符 sw<> 和 w<> 感到困惑.

Please elaborate on the difference between sw<N>dp and w<N>dp, in a simple way. I have studied the complete documentation of screen sizes but am confused between these two qualifiers sw<> and w<>.

推荐答案

Android 设备屏幕是矩形.矩形有两条边，一条比另一条短.我们称短的 A 和长的 B.

Android device screens are rectangles. Rectangles have two sides, one shorter than the other. Let's call the short one A and the long one B.

-swNNNdp 表示如果 A 的长度大于或等于 NNN dp，则使用这些资源"

-swNNNdp indicates "use these resources if A is greater than or equal to NNN dp in length"

-wNNNdp 表示如果当前持有的设备宽度大于或等于 NNN dp"

-wNNNdp indicates "use these resources if the width of the device, as presently held, is greater than or equal to NNN dp"

当用户在纵向和横向之间旋转设备时，宽度会发生变化(为 A 或 B)，但 A(最短宽度)始终相同.

When the user rotates the device between portrait and landscape, the width will change (to be A or B), but A (the shortest width) is always the same.
