How to Integrate Emojis in an Android App? (original) (raw)

Last Updated : 15 Jul, 2025

**Emojis certainly make the app more interesting and fun to interact with. In this article, let's learn how to add Emojis in our own Android App by creating a simple application that looks like a messaging app.

**Why do we need Emojis?

**Approach

**Step 1: Create a new Android Studio project

To create a new project in Android Studio please refer to **How to Create/Start a New Project in Android Studio. **Note that select **Java as the programming language.

**Step 2: Add the following dependency to build.gradle(:app)

In order to use emojis in the app, add its dependency to build.gradle(:app) file. Add **any one of the three dependencies:

implementation 'com.vanniktech:emoji-google:0.6.0'

implementation 'com.vanniktech:emoji-ios:0.6.0'

implementation 'com.vanniktech:emoji-twitter:0.6.0'

Each dependency signifies the emoji set we are importing. That is, either from **ios, or **Google, or **Twitter.

**Step 3: Working with activity_main.xml file

In this example, make the app look like a chat app. For this, use two **Buttons. One to add emojis and one to send the message. Add also an **EditText where the user will type the message. This is how the **activity_main.xml looks like:

activity_main.xml `

<androidx.constraintlayout.widget.ConstraintLayout 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:id="@+id/rootView" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#43a047" android:padding="8dp" tools:context=".MainActivity">

<LinearLayout
    android:id="@+id/llTextViews"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:orientation="vertical"
    app:layout_constraintBottom_toTopOf="@id/etEmoji"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintEnd_toEndOf="parent">
</LinearLayout>

<com.vanniktech.emoji.EmojiEditText
    android:id="@+id/etEmoji"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:hint="Say something to GeeksForGeeks..."
    app:emojiSize="30sp"
    android:textColor="@android:color/white"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toStartOf="@id/btnEmojis"
    app:layout_constraintStart_toStartOf="parent"/>

<Button
    android:id="@+id/btnEmojis"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Emojis"
    app:layout_constraintEnd_toStartOf="@id/btnSend"
    app:layout_constraintTop_toTopOf="@id/etEmoji"
    app:layout_constraintBottom_toBottomOf="@id/etEmoji"/>

<Button
    android:id="@+id/btnSend"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Send"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintTop_toTopOf="@id/etEmoji"
    app:layout_constraintBottom_toBottomOf="@id/etEmoji"/>

</androidx.constraintlayout.widget.ConstraintLayout>

`

**Step 4: Create a layout file called text_view_emoji.xml

Create a layout to define how the emoji should look like. Its main purpose is to define the size of the emoji. It will also display the messages which we send. Create a new layout by clicking: **app ->**res -> layout(right-click) -> New -> Layout Resource File.

newLayout

Name this as **text_view_emoji.This is how the **text_view_emoji.xml looks like:

text_view_emoji.xml `

<com.vanniktech.emoji.EmojiTextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_marginBottom="16dp" app:emojiSize="30sp" android:textSize="30sp" android:textColor="@android:color/white"/>

`

**Step 5: Create a class called EmojiApplication

Depending on which emoji set the user wants to have, set up the corresponding providing here. By setting up the **EmojiManager here, make sure that the user can use them anywhere in the app. To create a new class, click on: **File -> New -> **Java Class.

newClass

Name this as **EmojiApplication.This is how the **EmojiApplication.java looks like:

EmojiApplication.java `

import android.app.Application;

import com.vanniktech.emoji.EmojiManager; import com.vanniktech.emoji.google.GoogleEmojiProvider;

public class EmojiApplication extends Application {

@Override
public void onCreate() {
    super.onCreate();
    EmojiManager.install(new GoogleEmojiProvider());
}

}

`

**Note: Do not forget to add this new class in the **AndroidManifest.xml file. This is how the **AndroidManifest.xml looks like after adding:

AndroidManifest.xml `

<application
    android:name=".EmojiApplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

`

**Step 6: Working with the MainActivity.java file

Here, write a function to inflate the **EmojiTextView. The **LayoutInfalter is used to convert a **View or a **ViewGroupwritten in XML to a View in Java which can use in the code. Also, set the **onCreate() function here. After all these changes, this is how the **MainActivity.java looks like:

MainActivity.java `

import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.LinearLayout; import com.vanniktech.emoji.EmojiPopup; import com.vanniktech.emoji.EmojiTextView;

public class MainActivity extends AppCompatActivity { EditText etEmoji; LinearLayout llTextViews;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    etEmoji=findViewById(R.id.etEmoji);
    llTextViews=findViewById(R.id.llTextViews);

    final EmojiPopup popup = EmojiPopup.Builder
            .fromRootView(findViewById(R.id.rootView)).build(etEmoji);

    Button btnEmojis=findViewById(R.id.btnEmojis);
    btnEmojis.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            popup.toggle();
        }
    });

    Button btnSend=findViewById(R.id.btnSend);
    btnSend.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            llTextViews.addView(getEmojiTextView());
            etEmoji.getText().clear();
        }
    });
}

private EmojiTextView getEmojiTextView() {
    EmojiTextView tvEmoji = (EmojiTextView) LayoutInflater
            .from(getApplicationContext())
            .inflate(R.layout.text_view_emoji, llTextViews,false);
    tvEmoji.setText(etEmoji.getText().toString());
    return tvEmoji;
}

}

`

**Output: Run on Emulator
