icons

问题 I'm new to smartphone programming and have joined a project using React Native and NativeBase. I'd like to include an image/icon in each Item in a Picker, which doesn't seem like an exotic concept, but it doesn't seem to be supported and I can't find anyone discussing doing it on SO or by Googling. I've tried a couple ways of adding things inside the <Picker.Item> and </Picker.Item> but anything put there seems to simply be ignored. Is it possible or is there a different approach to do what I

问题 I am working on a test android app. The problem I am having is that the app icon is very very small. I have added different sizes in different mipmap folder but the size is still the same = very tiny. I have tried to add large size in all of the folders but it didn't work either.

问题 Some Windows native applications have a question mark icon on the title bar. It's usually at the right edge, just near the close button. How can I do this in a C# WinForms application?

问题 I have an Android appwidget which shows icons of other applications on it. I get the other applications icons with appInfo.loadIcon and then I set it to the widgets with setImageViewBitmap. The problem is that if I have too many icons on the widget, I get "FAILED BINDER TRANSACTION" error. I understand that it's from a size limit and the solution it to use the image uri instead of the bitmap itself. Is there an accessible URI to other applications' icons? Thanks. 回答1: Try android.resource://

问题 So as to waste some more time today, I converted a .jpg file to .ico and put it in favicon.ico. The .jpg is less than 1KB big; the .ico file is ** 60KB ** !!, bigger than the html page I'm putting it on. I used the online converter at http://www.coolutils.com/online/image-converter/ 60KB cannot be a reasonable size for an icon. Can it? Thanks! -- pete 回答1: .ico files are unique because they can contain multiple resolution images and the most appropriate one is used. The site probably created

问题 I remember reading somewhere that you can provide your own icons without having them pass them through the automatic gloss effect when compiling an iphone app, but I can't remember how to do it, and not sure where it was in the docs. Anyone here remembers? thanks! 回答1: Add the "UIPrerenderedIcon" to your info.plist file, change it to be a boolean and make it true. (In 2.0 of the iPhone OS you could also leave it as a string and use YES or NO, but that no longer works in 2.1.) 回答2: Stephen is

问题 Can I use somehow the filetype images from my operating system and display them in my application? 回答1: If you know the file name of the file whose icon you want, you can use the ExtractAssociatedIcon function for that purpose. e.g. Icon ico = Icon.ExtractAssociatedIcon(@"C:\WINDOWS\system32\notepad.exe"); There is a catch to this method though. According to its documentation, When ExtractAssociatedIcon is used with bitmaps, a thumbnail image may be returned instead of an icon if the system
