How do I resize this image or what kind of methods should I use to make this image well-matched. Secondly, is there any way to make backgrounds like this universal for devices with different

问题 I use an iPhone 6 and I launch Skype and my app. My app launches in low resolution (seems like non-retina) and Skype launches in high resolution - status bar resolution stays the same as in home menu of iOS, while the status bar in my app seems "bigger". screenshot The one on the left (mine) is clearly lower resolution. What could be causing that ? 回答1: Make sure you have Launch Screen or launch Images at correct resolution for iPhone 6 or 6 Plus, otherwise your application will run in

问题 I am using the OpenTk GameWindow. I have been adding graphics settings to my project. But I cannot figure out how to correctly change the resolution or go in or out of fullscreen mode in runtime. Can someone please explain the correct procedure to changing the resolution and/or fullscreen state in while the game is running. Using WindowState = WindowState.Fullscreen; and WindowState = WindowState.Fullscreen; work, but they modify the viewing area and setting GL.Viewport doesn't fix it. I am

问题 I have and imageview that i use throughout my app. It can hold a picture from the gallery or from the camera. In the end I upload it to a webserver using php.

问题 I'm creating an Android application. The main activity layout will have a background image that will wrap with the whole screen. What resolution should I use to create the background image?

问题 I know many languages have the ability to round to a certain number of decimal places, such as with the Python: >>> print round (123.123, 1) 123.1 >>> print round (123.123, -1) 120.0 But how do we round to an arbitrary resolution that is not a decimal multiple. For example, if I wanted to round a number to the nearest half or third so that: 123.123 rounded to nearest half is 123.0. 456.456 rounded to nearest half is 456.5. 789.789 rounded to nearest half is 790.0. 123.123 rounded to nearest

问题 i wish to write the layout and code just once so that it would look good on all devices . i've tried many ways (yes, including what google suggests, to use DP and also add multiple layout files) , but none really solves the problem of having to deal with a new situation each time there is a new device with a random resolution and density. the DP usage is just an XML trick that lets the dimensions stay the same on all screens like a ruler (for example , 1cm stays 1cm on all screens) ,so it's
