据我所知，匹配DPI和大小预选赛设备的实际屏幕属性（物理DPI和大小），而是基于没有什么$ P $由设备制造商pdefined。

As I understand, the matching dpi and size qualifiers for the device are based not on actual screen properties (physical dpi and size), but instead on what was predefined by the device manufacturer.

有没有什么抽象的DPI /尺寸为不同的设备列表？

Is there a list of what abstract dpi/sizes are for different devices?

推荐答案

我觉得有一些误解。这不是一个免费为所有在那里制造商可以选择任何他们想要的。这是事实，它们具有一定的灵活性，在采摘的密度，但不是很多 - 最终结合物理屏幕分辨率的密度明确地导致屏幕水桶和该映射是由平台指定偏偏的方式。此外，选择的密度几乎总是将是你所期望的，给设备的实际DPI什么。制造商可以推动与去一个更高的密度 - 这将导致屏幕并有可能向下移动到一个较低的屏幕大小水桶上一个更大的用户界面 - 但是这是非常罕见的。

I think there is some misunderstanding. This isn't a free-for-all where manufacturers can pick whatever they want. It is true that they have some flexibility in picking the density, but not a lot -- ultimately the density combined with the physical screen resolution explicitly results in a screen bucket and the way that mapping happens is specified by the platform. Also, the density selected is almost always going to be what you would expect give the actual DPI of the device. A manufacturer may push that with going to a higher density -- this results in a larger UI on the screen and likely a move down to a lower screen size bucket -- but this is extremely rare.

所以。 320×240的屏幕只能算是小规模的低密度屏幕。仅此而已。

So. A 320x240 screen can only be a small size low density screen. Nothing else.

与小480x320屏幕的设备是普遍正常大小中等密度。

Devices with 480x320 screens are universally normal size medium density.

与480×800（或x852）屏幕的设备是当时一个普通大小的高密度的绝大多数。有一些罕见的设备与大屏幕480x800的像戴尔Streak - 这是一个中等密度的屏幕和大水桶。你可以告诉一个设备是这样的，因为......嗯，它有一个大屏幕。 ：}

Devices with 480x800 (or x852) screens are the vast majority of the time a normal size high density. There are some rare devices with a large 480x800 screen like the Dell Streak -- these are a medium density screen and large bucket. You can tell a device is like this because... well, it has a large screen. :}

该器件运费的qHD屏幕不能去到xhdpi桶（试试吧，你最终会得到一个屏幕太小，兼容），所以这些仍然是高密度的，他们也仍正常大小，因为它们不够大以在大桶内。换句话说，这只是另一部手机屏幕布局多一点的空间。

The devices shipping with qHD screens can't go up to the xhdpi bucket (try it, you end up with a screen too small to be compatible), so these are still high density and they are also still normal size because they aren't sufficiently large to be in the large bucket. In other words, this is just another phone screen with a little more space for layout.

10平板电脑，你看到的是1280×800或1280×720，这是MDPI屏幕，并在XLARGE桶。

The 10" tablets you see are 1280x800 or 1280x720. These are mdpi screens, and in the xlarge bucket.

安卓3.2支持7屏幕这是一般1024x720 MDPI。这些最终在大尺寸桶。

Android 3.2 is supporting 7" screens which are generally 1024x720 mdpi. These end up in the large size bucket.

当然还有很多其他的屏幕，你可以想像，但我不知道离手设备的出货量与他们的，并考虑到我们已经覆盖小，中，大，XLARGE实在没有什么太有趣他们。例如，一个640×480大小的手机屏幕将是华电国际的密度和小屏幕桶。

There are of course many other screens you can imagine, but I don't know off-hand of devices shipping with them and given that we have already covered small, normal, large, and xlarge there is really nothing too interesting about them. For example a 640x480 phone size screen would be hdpi density and small screen bucket.
