AndroidTranslate, using Google Translate API in Android application.

It’s a simple Android Application using google-api-translate-java to involve Google Translate, to translate the text input in the TextView in English to French.
In order to use google-api-translate-java in our application, we have to do some preparation as described in the article google-api-translate-java.
In our project, we have to grand permission to access internet, add the code in AndroidMainfest.xml.

AndroidMainfest.xml

encoding=”utf-8″?>
schemas.android.com/apk/res/android”
   package=”com.exercise.AndroidTranslate”
   android:versionCode=”1″
   android:versionName=”1.0″>
                    android:label=”@string/app_name”>

Modify main.xml to include a EditText to input text to be translate, a Button to start translation, and a TextView to display the result.

main.xml

 android:orientation=”vertical”
 android:layout_width=”fill_parent”
 android:layout_height=”fill_parent”
 >
<textview
 android:layout_width=”fill_parent”
 android:layout_height=”wrap_content”
 android:text=”@string/hello”
 />
<edittext
android:id=”@+id/InputText”
 android:layout_width=”fill_parent”
 android:layout_height=”wrap_content”
/>
<button
android:id=”@+id/TranslateButton”
 android:layout_width=”fill_parent”
 android:layout_height=”wrap_content”
 android:text=”Translate”
/>
<textview
android:id=”@+id/OutputText”
 android:layout_width=”fill_parent”
 android:layout_height=”wrap_content”
 />
</textview
</button
</edittext
</textview

Finally, modify AndroidTranslate.java to implement the function.

AndroidTranslate.java

package com.exercise.AndroidTranslate;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import com.google.api.translate.Language;
import com.google.api.translate.Translate;
public class AndroidTranslate extends Activity {
EditText MyInputText;
Button MyTranslateButton;
TextView MyOutputText;
 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.main);
     MyInputText = (EditText)findViewById(R.id.InputText);
     MyTranslateButton = (Button)findViewById(R.id.TranslateButton);
     MyOutputText = (TextView)findViewById(R.id.OutputText);
     MyTranslateButton.setOnClickListener(MyTranslateButtonOnClickListener);
 }
 private Button.OnClickListener MyTranslateButtonOnClickListener
   = new Button.OnClickListener(){
 @Override
 public void onClick(View v) {
  // TODO Auto-generated method stub
  String InputString;
  String OutputString = null;
  InputString = MyInputText.getText().toString();
  try {
   Translate.setHttpReferrer(“http://android-er.blogspot.com/”);
   OutputString = Translate.execute(InputString,
     Language.ENGLISH, Language.FRENCH);
  } catch (Exception ex) {
   ex.printStackTrace();
   OutputString = “Error”;
     }
  MyOutputText.setText(OutputString);
 }
 };
}
