Android dpi Ice Cream Sandwich 问题

Question

我有两个值文件夹:

• 值(value)观
• 值-sw320dp

我在带有 Ice Cream Sandwich 的设备上运行该应用程序。

尽管设备具有 240 dpi 显示屏，但它从 values-sw320dp 文件夹而不是 values 文件夹中读取值。

造成这种行为的原因是什么？

Answer 1

sw 限定符用于根据设备上可用的最小宽度定义值(因此，当处于纵向模式时)。它不是基于设备密度。

The fundamental size of a screen, as indicated by the shortest dimension of the available screen area. Specifically, the device's smallestWidth is the shortest of the screen's available height and width (you may also think of it as the "smallest possible width" for the screen). You can use this qualifier to ensure that, regardless of the screen's current orientation, your application has at least dps of width available for its UI.
