问题
I'm writing a game for Android and am laying out the playing screen myself, handling both vertical and horizontal orientations, and haven't done anything if the width and height are the same.
Does anybody know of at least one Android device that has a perfectly square screen resolution?
回答1:
I believe the WIMM ONE is the only square screen Android device out there. It has capacitive touch display at 160x160.
回答2:
The MotoACTV is 220x176 (not square but close), the WIMM One is 160x160 (square).
The MotoACTV has been rooted, but the default device runs a customized Android. It's a pretty cool device, though. The WIMM is slick and runs a more-standard Android.

None the I'm aware of. Every device I'm familiar with has a distinctive "portrait" vs "landscape" mode.
It would probably be wise to make sure your code can always gracefully handle portrait vs landscape - even if you ever happen to run across a square device.
Conversely, if you want a square - just "crop" the image appropriately. The cropping, of course, will become "zero" if you ever encounter this hypothetical "square screen". :)

This is a rather late answer to this question, but things have changed somewhat since then, and although there are still no mainstream Android devices with square screens, there are 3 square BlackBerry devices (Q10, Q5, and Passport) that can run Android apps, and so would fall under that criteria. Interestingly, when an app is run on a square BlackBerry Passport, and the device is rotated to its side, the app also rotates, however none of the onPause(), onStop(), or onDestroy() events are called, and so the activity is not destroyed and re-created, but the current activity layout is re-used. So, in that respect, nothing happens, and you don't have to worry about saving/loading resources and such.
This behaviour is actually built-in in Android -- it will only destroy and re-create an activity, if the screen dimensions change. The API docs don't talk about this edge case, as there are no square Android devices, but you can see that the reason for destroying and re-creating the activity during orientation change is to load alternative resources specific for the new orientation. Since rotating a square device doesn't change the screen dimensions, there is no need to load alternative resources, and therefore, there's no need to destory and re-create an activity. I hope that helps.

Yes, the Motorola Flipout is one.
