如何在运行时为S60程序提供多国语言支持

我准备示范，如何使应用程序在运行时支持多国语言。下面的例子中，我使用了3种语言：英语、法语和德语。

修改MMP文件

第一步是修改MMP文件。在MMP文件中你可以看到这样一行：

[Copy to clipboard]

CODE:

LANG SC

修改成：

[Copy to clipboard]

CODE:

LANG 01 02 03

创建3种语言文件

我们将支持3种语言，英语、法语、德语，本地文件的扩展名分别为：l01，l02和l03。你可以在本地化使用所有的字符。

修改LOC文件

现在你需要修改成下面的LOC文件

[Copy to clipboard]

CODE:

// 01 = (British) English
#ifdef LANGUAGE_01
#include "MultiLang.l01"
#endif

// 02 = French
#ifdef LANGUAGE_02
#include "MultiLang.l02"
#endif

// 03 = German
#ifdef LANGUAGE_03
#include "MultiLang.l03"
#endif

修改YourAppAif.rss文件

YourAppaif.rss 文件中需要像这样本地化你的应用程序标题：

[Copy to clipboard]

CODE:

RESOURCE AIF_DATA
{
caption_list=
{
CAPTION { code=01; caption="MultiLang"; }, // Eglish
CAPTION { code=02; caption="MultiLang"; }, // French
CAPTION { code=03; caption="MultiLang"; } // German
};

app_uid=0x02a5dd83;
num_icons=2;
embeddability=KAppNotEmbeddable;
newfile=KAppDoesNotSupportNewFile;
}

修改由CAknApplication继承来的类

重写CEikApplication 中的 ResourceFileName() 函数到你的CYourApplicationApp 类.

[Copy to clipboard]

CODE:

TFileName CMultiLangApp::ResourceFileName() const
{
return TFileName();
}

修改AppUi 类

首先，你需要为AppUi 类中的 ConstructL()函数的BaseConstructL() 中传递ENonStandardResourceFile 参数：

[Copy to clipboard]

CODE:

void CMultiLangAppUi::ConstructL()
{
BaseConstructL( ENonStandardResourceFile );
//...
}

接着，在你的AppUi类中创建下列新的函数：

[Copy to clipboard]

CODE:

void CMultiLangAppUi::ChooseLanguageL(TInt aLanguageIndex)
{
_LIT(KResourceFileName, "MultiLang.r%02d");
TFileName resFileName;

resFileName.Format(KResourceFileName, aLanguageIndex);

#if !defined(__WINS__) && !defined(__WINSCW__)
// Device
CompleteWithAppPath(resFileName);
#else
// Emulator
resFileName.Insert(0, KEmulatorPath);
#endif

if (iOffset) iCoeEnv->DeleteResourceFile(iOffset);
iOffset = iCoeEnv->AddResourceFileL(resFileName);
}

现在你可以调用 ChooseLanguageL([LanguageIndex]) 函数来实现语言的切换了。

修改PKG文件

添加以下几行到你的打包文件中。

[Copy to clipboard]

CODE:

"\Symbian\7.0s\Series60_v21\Epoc32\data\z\system\apps\MultiLang\MultiLang.r01"       -"!:\system\apps\MultiLang\MultiLang.r01"
"\Symbian\7.0s\Series60_v21\Epoc32\data\z\system\apps\MultiLang\MultiLang.r02"       -"!:\system\apps\MultiLang\MultiLang.r02"
"\Symbian\7.0s\Series60_v21\Epoc32\data\z\system\apps\MultiLang\MultiLang.r03"       -"!:\system\apps\MultiLang\MultiLang.r03"
"\Symbian\7.0s\Series60_v21\Epoc32\data\z\system\apps\MultiLang\MultiLang_caption.r01" -"!:\system\apps\MultiLang\MultiLang_caption.r01"
"\Symbian\7.0s\Series60_v21\Epoc32\data\z\system\apps\MultiLang\MultiLang_caption.r02" -"!:\system\apps\MultiLang\MultiLang_caption.r02"
"\Symbian\7.0s\Series60_v21\Epoc32\data\z\system\apps\MultiLang\MultiLang_caption.r03" -"!:\system\apps\MultiLang\MultiLang_caption.r03"

How to provide the Multi-Language support at runtime for Series 60

I’m going to demonstrate how to make an application supports mutli-language at run time. In the following example I’ve used three language support, English, French and German.

Change the MMP file.

The first step is to make a modification in the MMP file. In the MMP file you can see one line like this:

[Copy to clipboard]

CODE:

LANG SC

Replace that with the following line:

[Copy to clipboard]

CODE:

LANG 01 02 03

Create three localization files

As we are going to give support for three languages, English, French and German, the localization file extension should be l01, l02 and l03 respectively. You can put all the strings in this localization files.

Change the LOC file.

Now you have to change the LOC file below:

[Copy to clipboard]

CODE:

Change the YourAppAif.rss file

YourAppaif.rss should be like this to localize your application’s caption:

[Copy to clipboard]

CODE:

Change the class derived from CAknApplication

Over-ride ResourceFileName() function from CEikApplication to your CYourApplicationApp calss.

[Copy to clipboard]

CODE:

TFileName CMultiLangApp::ResourceFileName() const
{
return TFileName();
}

Changes required in the AppUi class

First of all you have to pass ENonStandardResourceFile for the function call of BaseConstructL() in your AppUi class’s ConstructL() function.

[Copy to clipboard]

CODE:

void CMultiLangAppUi::ConstructL()
{
BaseConstructL( ENonStandardResourceFile );
//...
}

Next create the following new function in your AppUi class.

[Copy to clipboard]

CODE:

Now you can change the language of the application by calling ChooseLanguageL([LanguageIndex]) function.

Changes in the PKG file

Put the following lines to your package file.

[Copy to clipboard]

CODE:

You can download the example application from here.

Users of the S60 3rd Edition platform will find an updated version of the application here.
