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）：
