问题 Is it possible to manually select a strings.xml file without changing the language of your device? I would like to have Button to switch between two languages, but all i found is to use the build-in feature of android studio to create different strings.xml , which are selected by your localization. 回答1: If you want to use a different strings.xml you have to switch localization. This can be done programmatically but is highly not recommended because you will mess with the system. You can

问题 I'm creating a win32 application and initialized my statusbar width variables in my WM_CREATE switch case. case WM_CREATE: { int statwidths[] = { 200, -1 }; } break; I would like to access statwidths[ 0 ] in my WM_SIZE switch case as that number will be used to determine the size of the rest of my windows in my program. case WM_SIZE: { int OpenDocumentWidth = statwidths[ 0 ]; } break; Is there a way to do this? They are both in the same switch statement in the same file. 回答1: If these are

问题 I am currently trying to get some casting on generic types done. So the base idea is to have a method which accepts a generic Type and does different stuff depending on which type gets passed in. For simplicity reasons I will just showcase the use of float , bool and default The setup looks something like this (where T is a generic type defined by the class itself): protected T DoStuff(T value) { switch (value) { case float floatValue: float result = DoFloatStuff(floatValue); switch (result)

问题 Below Code, I wrote to execute the switch-case statement, for each condition. Now I am thinking to remove the switch-case statement and apply some design pattern to overcome this issue. // main iteration - for every sheet for (Entry>> entry : testCaseSheetsDataMap.entrySet()) { String sheetNameKey = entry.getKey().trim(); String testCaseName = testCaseSheetMasterMap.get(sheetNameKey).trim(); List<Map<String, Object>> executableRowsList = new ArrayList<Map<String, Object>>();

问题 Consider the following code segment... public static UserStatus getEnum(int code) { switch (code) { case 0: return PENDING; case 1: return ACTIVE; case 2: return SUSPENDED; case 3: return DELETED; case 4: return LOGIN_DISABLED; default: return null; } } Now number 3 and 4 in cases(case 3 and case 4) are detected as magic numbers by SONAR. To avoid that issue I changed my code segment as follows... public static UserStatus getEnum(int code) { final int Pending=0; final int Active=1; final int

问题 Suppose I have N different integral values known at compile time, V_1 through V_N. Consider the following structures: const int x = foo(); switch(x) { case V_1: { /* commands for V_1 which don't change x */ } break; case V_2: { /* commands for V_1 which don't change x */ } break; /* ... */ case V_N: { /* commands for V_1 which don't change x */ } break; } versus const int x = foo(); if (x == V_1) { /* commands for V_1 which don't change x */ } else if (x == V_2) { /* commands for V_2 which
