【问题描述】：

我正在尝试在我的 android 应用程序中使用 Yandex 翻译器，但它给出了错误。在 Java 应用程序（主要）中进行测试时，它可以完美运行。我的问题是什么？

主要代码：

import com.rmtheis.yandtran.language.Language;
import com.rmtheis.yandtran.translate.Translate;
import com.veryinteligent.jarvas.R;

import com.veryinteligent.jarvas.activity.WordCommands;

import android.app.Activity;
import android.os.Bundle;

public class YandexTranslator extends Activity

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.wordcommands);
        Translate.setKey(WordCommands.myKey);
        String term = "obrigado por me ajudar";
        try 
            term = Translate.execute(term, Language.PORTUGUESE, Language.ENGLISH);
         catch (Exception e) 
            // TODO Auto-generated catch block
            e.printStackTrace();
        
        System.out.println(term);
    
  

import com.rmtheis.yandtran.language.Language;
import com.rmtheis.yandtran.translate.Translate;

public class TranslationTester 

    public static void main(String[] args) 
        // TODO Auto-generated method stub
        Translate.setKey("trnsl.1.1.20160515T173032Z.cb8002677c95725e.93f4f996a1647d5d0c6e336758723a8bb1bb41b4");

        String term = "abrir vá";
        try 
            term = Translate.execute(term, Language.PORTUGUESE, Language.ENGLISH);
         catch (Exception e) 
            // TODO Auto-generated catch block
            e.printStackTrace();
        
        System.out.println(term);

    

错误：

【问题讨论】：

改进了错误信息的格式；修正了一些措辞。

谢谢。我还是个初学者。

【参考方案1】：

我使用此代码here，它对我来说很好用

1：将json_simple-1.1.jar添加到你的项目Tutorial

2：将类代码从yandex-translator-java-api/src/com/rmtheis/yandtran/ 复制到您的项目中

3：将您的 API 密钥放入 ApiKeys.java

4：把这行翻译成一段文字：

    Translate.setKey(ApiKeys.YANDEX_API_KEY);

    String translatedText = Translate.execute("Hola, mundo!", Language.SPANISH, Language.ENGLISH);

5：如果您收到android.os.NetworkOnMainThreadException 错误，这是因为当应用程序尝试在其主线程上执行网络操作时抛出此异常，解决方案：

-- 在你的 YandexTranslatorApi.java 中添加这一行

static class RetrieveResponse extends AsyncTask<URL,Void,String>

        @Override
        protected String doInBackground(URL... params) 
            String result = "";
            try 
                result = retrieveResponse(params[0]);
             catch (Exception e) 
                e.printStackTrace();
            
            return result;
        
    

-- 在retrievePropString 和retrievePropArrString 方法中更改这一行：

final String response = retrieveResponse(url);

    

通过这个：

final String response = new RetrieveResponse().execute(url).get();

已编辑： 将<uses-permission android:name="android.permission.INTERNET" /> 添加到您的AndroidManifest.xml 祝你好运^_^
