问题 Hello I am trying to change the text color of the items in a list on a ListPreference pop up window. I have spent over an hour looking through all of the various style names but I can't find TextAppearance or anything that goes to this particular text. Thanks for your help! 回答1: You can't and you shouldn't. *Preference uses styles from com.android.internal.R.styleable which might be changed by manufactures. The idea of using the default ones is that every preference screen in your device look

问题 I'm working on a model written in Fortran 95, which I am completely new to. The concept of statement labels seems strange, and I've so far only found the explanation that the labels can be arbitrarily decided by the author, usually incrementing by 10's. Are there any practical uses of these labels, other than picking out more easily where a statement is ending? AND a generally accepted standard on how to label. 回答1: The only way I can think of statement labels being useful in modern Fortran

问题 CMake commands are valid in lower, upper, and mixed case. Mixing all of those together in one file however reduces the readability of the CMake code. Is there a tool for automatically correcting this kind of stylistic inconsistencies? 回答1: The answer by steveire links to the right resources, but let me explain explicitly in case those links vanish. CMake command are case insensitive but lower case is recommended according to CMake developer Brad King in 2012: Ancient CMake versions required

问题 HI, I'm currently working on a project that uses Flex and Java. In Java we easily enforced a coding standard with Checkstyle, and we want to do this for Flex. Does anybody know of a tool similar to Checkstyle that would allow coding standard checks? (I've googled for this but found only one project written in python and it seams abandoned) Thanks 回答1: The long and the short is that there is... kind of, but only for Actionscript, and you have to test it yourself... There is a prototype of an

问题 I keep running across little conventions like __KERNEL__ . Are the __ in this case a naming convention used by kernel developers or is it a syntax specific reason for naming a macro this way? There are many examples of this throughout the code. For example some functions and variables begin with an _ or even __ . Is there a specific reason for this? It seems pretty widely used and I just need some clarification as to whether these things have a syntactical purpose or is it simply a naming

问题 Is it ok to use a module referencing with more than two dots in a path? Like in this example: # Project structure: # sound # __init__.py # codecs # __init__.py # echo # __init__.py # nix # __init__.py # way1.py # way2.py # way2.py source code from .way1 import echo_way1 from ...codecs import cool_codec # Do something with echo_way1 and cool_codec. UPD: Changed the example. And I know, this will work in a practice. But is it a common method of importing or not? 回答1: From PEP8: Absolute imports

问题 Like: public $foo = null, $bar = 10; protected $_stuff = null, $_moreStuff = 5; A lot of people seem to do this. Why? Isn't this inconsistent naming (like some PHP functions are :))? 回答1: It really comes down to one thing: personal preference. I, personally, am also one who uses that naming convention. Prefixing anything that is protected or private with an underscore, be it a variable or a function, lets myself and any other programmer who I regularly work with know that that variable is

问题 I ask this question mostly in regards to C programming, but insights on any language are welcome. When it comes to C, I know it only lets variable declarations occur at the very beginning of a block of code. And I have been under the impression that one should declare all variables to be used within a function at the very beginning of the function. But there are many occasions where I'll have a variable that is only used within a loop (or similar block). an example would be a temporary

问题 The problem: Here is what I do body { border: 0; } as was suggested here: Removing border from WebBrowser control But this only works when we use the following doctype: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> When doctype is changed to <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"> the nasty border won't go away! But I need the XHTML doctype in order for "position: fixed" to work in IE. Any suggestions? The code: HTML: <?xml version="1.0" encoding="UTF
