converter

问题 I want the user to enter a temperature in Celsius and display the temperature in fahrenheit and vice versa. I think TextChangedListener would be perfect to convert without any button pressing. The values go on changing as the user types in. The biggest problem I'm having is that the EditText won't take any input. The moment I input anything, the app force closes. Please tell me what's wrong.Here's my code. public class MainActivity extends ActionBarActivity { EditText C, F; Button exit;

问题 I have a package table. I want to change automatically the currency of each amount depending on the location of the user. For example, if the user is from UK, it will change to pounds, if from Australia it will be AUD. I have looked for a tutorial in google but all I can see is a conversion table, like this one not. How will I do this using HTML and javascript? <style> td{ text-align: center; } </style> <table> <tr> <td></td> <td> $100 </td> <td> $200 </td> <td> $300 </td> </tr> <tr> <td>

问题 Im new in javascript and I'm trying to make a simple currency converter, it is working fine when I select "£Pound" "£Pound" or "£Pound" "R$Real" but when I select "R$Real" "R$Real" runs the "Pound" "R$Real" calculation. I spent hours trying to figure this out (very frustrating). How to fix it? Is there another way to do it? (also tried using " if " and " else if " same issue). Thanks! Here`s the HTML : <label>Amount:</label> <input type="text" id="amount" /> <label>From:</label> <select id=

问题 I'm trying to use Ghostscript to convert my files in PDF to PCL. I'm able to convert one file with this command: gswin64c -dBATCH -dNOPAUSE -dSAFER -sDEVICE=pxlcolor -sOutputFile=[PCLPath].pcl [PDFPath].pdf It works fine, I think, if you see anything wrong or not needed please say me. The question is to convert all files in a folder, I don't know how to change the command line to do that, or what I have to do, maybe a script file?? Other question is if there is someway to accelerate the

问题 I have a json file that I need to convert to a csv file, but I am a little wary of trusting a json-to-csv converter site as the outputted data seems to be incorrect... so I was hoping to get some help here! I have the following json file structure: { "GroupName": "GrpName13", "Number": 3, "Notes": "Test Group ", "Units": [ { "UnitNumber": "TestUnit13", "DataSource": "Factory", "ContractNumber": "TestContract13", "CarNumber": "2", "ControllerTypeMessageId" : 4, "NumberOfLandings": 4,

问题 Is there any convenient tool/code that converts the standard cookie string format , e.g., NAME1: VALUE1; NAME2: VALUE2 to the libCURL cookie jar format , e.g., .netscape.com TRUE / FALSE 946684799 NETSCAPE_ID 100103 LibCurl seems to have such functionality and how to access it, like using shell command? 回答1: The chrome extension, edit this cookie has such functionality. Cookies can be exported into the Netscape cookie jar format. Before that, you need to set the default output format to

问题 I have an algorithm that converts RGB555 values to a System.Drawing.Color object; public static Color ToColor(ushort color) { int a = color & 0x8000; int r = color & 0x7C00; int g = color & 0x03E0; int b = color & 0x1F; int rgb = (r << 9) | (g << 6) | (b << 3); return Color.FromArgb((a * 0x1FE00) | rgb | ((rgb >> 5) & 0x070707)); } A friend wrote this method for me (bitwise shifting is a bit over my head) , what would be the most efficient way to reverse this code? Thanks for any advice, I've

问题 Is it possible to set a class to be serialised in a particular way by EclipseLink, without tagging it as such every time it is used? For example, say I had a class: class MyObj { private int a; private int b; public MyObj(int a, int b) { this.a = a; this.b = b; } ... } I want this to be stored in a column in the database as a string "a=1,b=2". I don't want it to be serialised to a blob, but to genuinely end up as a string in a VARCHAR column. I can do this with a converter, but I then need to

问题 I want to have a converter between this #include <ololo.h> #ifdef HAVE_QQQ #include <qqq.h> #endif char* ololize(char* s) { #ifdef HAVE_QQQ return qqq(s); #else return ololo(s); #endif } and something like this (include_angular "ololo.h") (p_ifdef "HAVE_QQQ" (include_angular "qqq.h")) (define_function "ololize" [(ptr char) "s"] (ptr char) (p_ifdef "HAVE_QQQ" (return (qqq s)) :else (return (ololo s))))) I.e. representation of a source code as a easily manageable tree, not from compiler's point

问题 I have a decimal to binary converter as seen below: print ("Welcome to August's decimal to binary converter.") while True: value = int(input("Please enter enter a positive integer to be converted to binary.")) invertedbinary = [] initialvalue = value while value >= 1: value = (value/2) invertedbinary.append(value) value = int(value) for n,i in enumerate(invertedbinary): if (round(i) == i): invertedbinary[n]=0 else: invertedbinary[n]=1 invertedbinary.reverse() result = ''.join(str(e) for e in
