问题 I need to get the color information of a specific point on screen of my android phone. Is there a way to do that through ADB? I am now using the build-in command screencap to capture the whole screen and then read the color of the specific point. However, it is too slow. 回答1: I will post an answer to my own question. The answer maybe device-specified (nexus7 2013), and you can adjust it to your own devices. 1.Firstly, I find out that the command screencap screen.png is quite slow because it

Screen and Mobile Stylesheets

问题 I've looked through the stack overflow topics on this question, as well as some google search results but I can't seem to solve my issue. I've created a stylesheet for mobile devices(mobile.css) which is essentially a copy of my main.css with changes to many of the attributes. When I load only mobile.css as the stylesheet it looks great on my iPhone, just how I want it to. However when I put both in, I am getting a mix of both, but more of the main.css Any idea why? <head> <link rel=

问题 I have read through a lot of different posts regarding this issue, but none of the solutions seemed to work for me. I started a new app and I placed the initial ViewController inside a navigation controller. I created a second view and linked them together on the storyboard with a segue. The segue works successfully, and I can see the data I am transferring in a print statement from the second screen, but the screen shows black. WelcomeScreen: override func prepareForSegue(segue:

How can I get the screen resolution using SDL2?

由 大兔子大兔子 提交于 2019-12-18 06:09:14
问题 I'm using pixel-perfect source images and SDL2 to make a program. When set to fullscreen, I'd like it to use the native resolution (the SDL_WINDOW_FULLSCREEN_DESKTOP flag) but only between a certain minimum resolution and a reasonable maximum one, after which it will stretch from the largest legal resolution. The problem is that I can only find references to the program's own window or program size on the SDL2 documentation. Is there any function in SDL from which I could retrieve the screen

How to support various iphone screen sizes as of 2014?

问题 I'm almost done building my first iPhone app and am trying to add a background image, and am finding it a little confusing, because nowadays there's like 3 or 4 different size screens among the different iPhone versions, with different resolutions to boot. So while I'm aware of the whole image@2x.png thing, I still don't know what I really need. If I want my app to run on iPhone 4/4s, 5s/5c, 6/6+, how many different versions of a background image do I need, and at what sizes and resolutions?

How do I track “screen on” time on Android?

问题 I'm trying to do something (theoretically) simple with my first app, but I need some help getting started. I'd like to build an app that tells me how long the screen on my Nexus 4 has been on today. Android shows me how long the screen has been on since last charge via Setting > Battery > Screen, but I'm not sure how to parse this data, or how to limit it to the current day. My research so far indicates that batterystats.bin is involved with screen tracking outlined above, and that I might be

问题 I'km working in Qt, i need help to get the physical size of the screen (monitor), In Qt one can get a QDesktopWidget from QApplication , I mean: QDesktopWidget *mydesk = QApplication::desktop(); The QDesktopwidget has some methods to get the resolution in pixels and some to get the the size in milimethers: mydesk-> widthMM(); mydesk->heightMM(); However, this does not correspond to the physical size, when I measure my screen with a ruler, there is a considerable difference.
