在Android支持多屏的问题上，对于dpi等概念完全搞不懂，所以我决定从头再研究一遍。我在 Android developer web site 中看到了这个例子:
The characteristics that define a device's generalized screen size and density are independent from each other. For example, a WVGA high-density screen is considered a normal size screen because its physical size is about the same as the T-Mobile G1 (Android's first device and baseline screen configuration). On the other hand, a WVGA medium-density screen is considered a large size screen. Although it offers the same resolution (the same number of pixels), the WVGA medium-density screen has a lower screen density, meaning that each pixel is physically larger and, thus, the entire screen is larger than the baseline (normal size) screen.
我不明白这两个设备如何具有相同的分辨率和相同的物理尺寸但不同的密度。
如果它们有不同的密度和相同的物理尺寸，它们不应该有不同的分辨率从而不同数量的物理像素?

有人可以为这个和这些类型的概念画一个插图吗？我真的很难想象这些东西。
谢谢。
最佳答案
I cannot understand how these two devices have the same resolution and the same physical size but different densities.
它们的物理尺寸不同，据说一个是正常尺寸，另一个是大尺寸，所以它们有如果它们具有相同的分辨率，则密度不同。
关于android - 有人可以帮我想象这个关于不同屏幕尺寸的例子吗？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17251637/
