Use Google Translate API in Android With No Limit
How to make translator App in Android Studio
In this article, I will teach you how to use Google translate API free unlimited request in any android app. This way is totally free to develop a translation app.
Here is the final output of this example.
I have created some steps to create a Language Translator App. Here you can see these steps in the following.
- Create a new project in the android studio go to File>New project
- Go to the manifest file declare permission for the internet. Like this.
3. Go to the app level Gradle file and put this line
useLibrary 'org.apache.http.legacy'Like this.
4. Now we have to create the translate_api class which extends AsyncTask class so that we can make network calls to the google translate API. Here is the source code.
If you want to learn more about AsyncTask the click here.
5. Create a simple design to translate the text. In this layout, I have created three EditText, On TextView, and a Button. First EditText is for text input, second is for taking the language code for text which is going to be translated, third EditText is for taking the language code in which language you want to translate. I have given the all language code list at the bottom of this article. Here is the design code.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="@+id/text"
android:hint="Enter text here.."
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<EditText
android:id="@+id/from_lang"
android:hint="Enter from language code"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<EditText
android:id="@+id/to_lang"
android:hint="Enter to language code"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:text="Translated Text:"
android:textSize="25sp"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/translated_text"
android:padding="10dp"
android:textSize="25sp"
android:layout_width="match_parent"
android:minHeight="100dp"
android:layout_height="wrap_content"/>
<Button
android:id="@+id/btnTranslate"
android:text="Translate"
android:layout_gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
</RelativeLayout>
</ScrollView>6. Here is the code for using our translate_api class in the activity class
package com.rashid.app.languagetranslation;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
EditText text,fromLangCode,toLangCode;
TextView translatedText;
Button btnTranslate;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initUi();
btnTranslate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
translate_api translate=new translate_api();
translate.setOnTranslationCompleteListener(new translate_api.OnTranslationCompleteListener() {
@Override
public void onStartTranslation() {
// here you can perform initial work before translated the text like displaying progress bar
}
@Override
public void onCompleted(String text) {
// "text" variable will give you the translated text
translatedText.setText(text);
}
@Override
public void onError(Exception e) {
}
});
translate.execute(text.getText().toString(),fromLangCode.getText().toString(),toLangCode.getText().toString());
}
});
}
private void initUi() {
text=findViewById(R.id.text);
fromLangCode=findViewById(R.id.from_lang);
toLangCode=findViewById(R.id.to_lang);
translatedText=findViewById(R.id.translated_text);
btnTranslate=findViewById(R.id.btnTranslate);
}
