目前我无法找出问题所在。对于以下代码，我不断收到相同的错误消息：

package com.example.test1;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import android.util.Log;
import com.memetix.mst.language.Language;
import com.memetix.mst.translate.Translate;

public class MainActivity extends Activity {
  private EditText text;
  private EditText text1;
  //private String translatedText;


  @Override
   public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Translate.setClientId("myId");
Translate.setClientSecret("mySecret");
    text = (EditText) findViewById(R.id.editText1);
    text1 = (EditText) findViewById(R.id.editText2);

    Button Trans1 = (Button)findViewById(R.id.button1);
    Trans1.setOnClickListener(new View.OnClickListener(){
    public void onClick(View view) {
        String word = text.getText().toString();
        try {
            String translatedText = Translate.execute(word, Language.ENGLISH, Language.GERMAN);
            text1.setText(translatedText);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    });
    }
    }

错误：

或者我已经尝试过另一种方式：

package com.example.test1;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import android.util.Log;
import com.memetix.mst.language.Language;
import com.memetix.mst.translate.Translate;

public class MainActivity extends Activity {
  private EditText text;
  private EditText text1;
  //private String translatedText;


  @Override
   public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Translate.setClientId("myId");
Translate.setClientSecret("mySecret");
    text = (EditText) findViewById(R.id.editText1);
    text1 = (EditText) findViewById(R.id.editText2);
    }

    public void onClick(View view) {
     switch (view.getId()) {
    case R.id.button1:
    if (text.getText().length() == 0) {
      Toast.makeText(this, "Please enter a word or phrase to translate...",
         Toast.LENGTH_LONG).show();
      return;
     }
    else {
    String word = text.getText().toString();
    try {
        String translatedText = Translate.execute(word, Language.ENGLISH, Language.GERMAN);
        text1.setText(translatedText);
    } catch (Exception e) {
        Toast.makeText(this, "flop...",
               Toast.LENGTH_LONG).show();
        e.printStackTrace();
    }
      }
     }
     }
     }

有了这个，它总是会捕获异常。

他们都没有返回结果。

主要问题（发现异常）：

02-14 16:50:17.281: W/System.err(1249): java.lang.Exception: [microsoft-translator-api] Error retrieving translation : null

引起：android.os.NetworkOnMainThreadException

这是因为您要么在不允许的 android 版本 >= 3.0 的主线程上执行网络操作。

使用 AsyncTask 从http://developer.android.com/reference/android/os/AsyncTask.html读取
