Question

我正在尝试在我的Android应用程序中使用Yandex转换程序，但它出错了。在Java应用程序（主要）中进行测试时，它可以完美地运行。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：

Answer 1

我使用此代码here，它对我来说很好用

1：将json_simple-1.1.jar添加到您的项目Tutorial

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

3：将您的API密钥放在ApiKeys.java

中

4：将这些行翻译成文字：

    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，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YandexTranslatorApi.java

中添加以下内容

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方法中更改此行：

final String response = retrieveResponse(url);

由此：

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

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