我写我自己的类来管理Android/iOS应用程序的翻译和我产生了这个代码。我将解释下面的代码,但它非常简单和简短。德尔福的TStringList查找方法无法找到项目
unit Localization;
interface
uses
System.Classes, System.SysUtils, Generics.Collections, Vcl.Dialogs;
//this class represents a single language (Italian, French, German...)
type
TLanguage = class
private
FTranslationList: TDictionary<string, string>;
function localize(const aWordId: string): string;
public
constructor Create;
destructor Destroy; override;
//methods
procedure addWord(const aIndex, aWord: string);
procedure removeWord(const aIndex: string);
end;
//this is a "container", it gathers all the languages in one place
type
TLocalization = class
private
FLanguagesList: TObjectList<TLanguage>;
FLocaleList: TStringList;
function getLang(Index: string): TLanguage;
public
constructor Create;
destructor Destroy; override;
//methods
function localize(const aLocaleId: string; const aIndex: string): string;
procedure addLanguage(const localeId: string);
//property to manage the languages
property Locale[Index: string]: TLanguage read getLang;
property langCount: integer read getCount;
end;
implementation
{ TLocalization }
{ add a new language to the class. }
{the localeId is a symbol like 'it' that represents the Italian language}
procedure TLocalization.addLanguage(const localeId: string);
begin
//add the language to the languages container
FLanguagesList.Add(TLanguage.Create);
//add the representation of the language.
FLocaleList.Add(localeId);
end;
constructor TLocalization.Create;
begin
FLanguagesList := TObjectList<TLanguage>.Create;
FLocaleList := TStringList.Create;
end;
destructor TLocalization.Destroy;
begin
FLanguagesList.Free;
FLocaleList.Free;
inherited;
end;
//ERROR HERE
function TLocalization.getLang(Index: string): TLanguage;
var i: integer;
begin
{ I search the locale id (for example 'it') if it's in the list. }
{ if it's in the list, I return the respective TLanguage object}
if not(FLocaleList.Find(Index, i)) then
Result := FLanguagesList.Items[i]
else
raise Exception.Create('Locale not found');
end;
function TLocalization.localize(const aLocaleId, aIndex: string): string;
var k: integer;
begin
k := 0;
if not(FLocaleList.Find(aLocaleId, k)) then
raise Exception.Create('Locale not found.');
//ho trovato il locale, adesso basta cercare la parola
Result := FLanguagesList.Items[k].localize(aIndex);
end;
{ TLanguage }
procedure TLanguage.addWord(const aIndex, aWord: string);
begin
FTranslationList.Add(aIndex, aWord);
end;
constructor TLanguage.Create;
begin
FTranslationList := TDictionary<string, string>.Create;
end;
destructor TLanguage.Destroy;
begin
FTranslationList.Free;
inherited;
end;
function TLanguage.localize(const aWordId: string): string;
begin
try
Result := FTranslationList.Items[aWordId];
except
Result := 'Not found.';
end;
end;
procedure TLanguage.removeWord(const aIndex: string);
begin
FTranslationList.Remove(aIndex);
end;
end.
以上被用作代码如下:
var a: TLocalization;
begin
a := TLocalization.Create;
a.addLanguage('it');
a.addLanguage('cse');
a.Locale['it'].addWord('test', 'Ciao mondo!');
a.Locale['cse'].addWord('test', 'fadfa ea!');
ButtonSomething.Text := a.localize('it', test);
end;
的TLocalization
类完成所有工作。正如你所看到的,我创建了变量a
,然后我添加一个语言到这个类(这是使用字典/字符串列表在内部管理的)。
我可以使用Locale[Index: string]
属性访问我已添加的语言,该属性返回一个TLanguage
,该类用于指示单个lang。在本地化方法的最后,我得到了我的翻译。
奇怪的是,我总是得到错误'Locale not found'
。任何想法?使用我发现这个调试器:
的FLocaleList
有项目,但我已经测试了这一点,我想我做错了什么上线71(在这里我使用查找功能)。我是否错过了索引?
好像不是.Find你应该尝试.IndexOf ... –
查找工作与排序名单 - 我不知道你在做什么。使用IndexOf或首先对列表进行排序。 – Jason
在这个问题的范围之外 - 看起来你在课堂上混合了两个术语。区域设置和语言代码(或ID)。你所说的区域设置通常被称为语言代码(或ID),例如, 'en','it'等,而区域设置是语言的特定子类(用于世界的特定区域),例如,对于英语,它可以是英式英语('en-gb'),美式英语('en-us')等。因此,在翻译文本时,首先检查文本是否仅存在于特定方言),如果不是,请使用该语言的通用语言。 – Victoria
