Android的自动检测语言 [英] android auto-language detection

问题描述

我试过这库，在对职位之一建议堆栈溢出，

我添加的lib的jar到我的构建路径，但我不能初始化DetectorFactory类语言的配置文件。

这是处理类的检测，如在他们的样品之一提示：

 类LanguageDetector {
    公共无效的init（字符串profileDirectory）抛出LangDetectException {
        DetectorFactory.loadProfile（profileDirectory）;
    }
    公共字符串检测（字符串文本）抛出LangDetectException {
        探测器探测器= DetectorFactory.create（）;
        detector.append（文本）;
        返回detector.detect（）;
    }
    公众的ArrayList＆LT;语言和GT; detectLangs（字符串文本）抛出LangDetectException {
        探测器探测器= DetectorFactory.create（）;
        detector.append（文本）;
        返回detector.getProbabilities（）;
    }
}
 

所有的语言文件会保存在myProject的/型材。
试图将类实例崩溃我的应用程序没有任何有用的消息logcat的

调用类（）：

  @覆盖
    公共无效onActivityCreated（捆绑savedInstanceState）{
        super.onActivityCreated（savedInstanceState）;
        上下文= this.getActivity（）getApplicationContext（）。
/ * LanguageDetector探测器= NULL;
        尝试{
            detector.init（/摇摆/配置文件）;
        }赶上（LangDetectException E）{
            // TODO自动生成catch块
            e.printStackTrace（）;
        } * /
        新GetDataTask（）执行（上下文）;    }
 

解决方案

更改 LanguageDetector 的方法静态的：

 类LanguageDetector {
    公共静态无效的init（字符串profileDirectory）抛出LangDetectException {
        DetectorFactory.loadProfile（profileDirectory）;
    }
    公共静态字符串检测（字符串文本）抛出LangDetectException {
        探测器探测器= DetectorFactory.create（）;
        detector.append（文本）;
        返回detector.detect（）;
    }
    公共静态的ArrayList＆LT;语言和GT; detectLangs（字符串文本）抛出LangDetectException {
        探测器探测器= DetectorFactory.create（）;
        detector.append（文本）;
        返回detector.getProbabilities（）;
    }
}
 

和使用方法如下：

  {尝试
    LanguageDetector.init（/摇摆/配置文件）; //＆LT;  - 你确定的配置文件是在这个位置？
}赶上（LangDetectException E）{
    // TODO自动生成catch块
    e.printStackTrace（）;
}字符串detectedLanguage = NULL;
尝试{
    detectedLanguage = LanguageDetector.detect（在德语模具IST EIN Beispiel。）;
}赶上（LangDetectException E）{
    // TODO自动生成catch块
    e.printStackTrace（）;
}如果（detectedLanguage！= NULL）{
    //这里实现你的逻辑
}
 

I tried this library, suggested in one of the posts on stack overflow,

I've added the lib's jar to my build-path, but I'm not able to initialize DetectorFactory class with the languages' profiles.

this is the class handling the detection, as suggested in one of their samples:

class LanguageDetector {
    public void init(String profileDirectory) throws LangDetectException {
        DetectorFactory.loadProfile(profileDirectory);
    }
    public String detect(String text) throws LangDetectException {
        Detector detector = DetectorFactory.create();
        detector.append(text);
        return detector.detect();
    }
    public ArrayList<Language> detectLangs(String text) throws LangDetectException {
        Detector detector = DetectorFactory.create();
        detector.append(text);
        return detector.getProbabilities();
    }
}

all languages profiles are stored under myProject/profiles. trying to instantiate the class crashes my app without any useful message to logcat

calling the class ():

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        context = this.getActivity().getApplicationContext();
/*        LanguageDetector detector = null;
        try {
            detector.init("/waggle/profiles");
        } catch (LangDetectException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }*/
        new GetDataTask().execute(context);

    }

解决方案

Change the methods in LanguageDetector to static:

class LanguageDetector {
    public static void init(String profileDirectory) throws LangDetectException {
        DetectorFactory.loadProfile(profileDirectory);
    }
    public static String detect(String text) throws LangDetectException {
        Detector detector = DetectorFactory.create();
        detector.append(text);
        return detector.detect();
    }
    public static ArrayList<Language> detectLangs(String text) throws LangDetectException {
        Detector detector = DetectorFactory.create();
        detector.append(text);
        return detector.getProbabilities();
    }
}

And use as follows:

try {
    LanguageDetector.init("/waggle/profiles"); // <-- Are you sure the profiles are at this location???
} catch (LangDetectException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

String detectedLanguage = null;
try {
    detectedLanguage = LanguageDetector.detect("Dies ist ein Beispiel in Deutsch.");
} catch (LangDetectException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

if (detectedLanguage != null) {
    // Implement your logic here
}
