Emojis 😛 are amazing way to express our feeling and deliver our thoughts that people with deferent languages can understand it even children’s can understand it. Any popular social network application provide you a set of Emojis. Take a look at your last messages to see how much you are using them. It’s very important to have them in your applications. Android OS can render Emojis on Text fields.

This article explains how to integrate emojis keyboard into your app easily with many customization options using SuperNova-Emoji library.

Android supernova emojis keyboard

1. Simple Integration

Below is the syntax of a simple integration for Emojis Keyboard. The EmojiIconActions constructer accept four parameters, Context, RootView, EmojiconEditText, and ImageView. 
Usually passing the parent layout as RootView is the best option to show the Emojis Keyboard above all views.
 The EmojiconEditText is a EditText with more custom attributes to enable emojis rendering. 
And the last parameter the ImageView will used to switch between the normal keyboard and the emojis keyboard.

To display emojis in TextView we will use EmojiconTextView which is also a TextView with more custom attributes to enable emojis rendering

EmojIconActions emojIcon= new EmojIconActions(this, rootView, emojiconEditText, 


If you want to use it in xml layout, we will use EmojiconEditText instead of the normal EditText.

    emojicon:emojiconSize="28sp" />

And EmojiconTextView instead of TextView



2. Change the default Toggle Icon

For switching between normal keyboard and emojis keyboard, 
you can call setIconsIds() method which takes two parameters, keyboard Icon ID and smiley Icon ID.


3. Using device default Emojis

SuperNove-Emoji allow you to use device emojis ins simple way, you need to set the boolean value of setUseSystemEmoji() and setUseSystemDefault() methods to TRUE in every EmojiconTextView and EmojiconEditText you use to display the emojis.



Xml attribute:


4. Changing Emojis Size

In order to change Emojis size, 
you have to change the text size by setting the value of setEmojiconSize() method.


XML code


5. Detect When the Keyboard Opened or closed

SuperNova-Emoji let you detect when the user open the keyboard or close it to take some actions if needed like show some views when the keyboard open and hide it when the keyboard closed. Use the below code block to achieve this.

emojIcon.setKeyboardListener(new EmojIconActions.KeyboardListener() {
            public void onKeyboardOpen() {

            public void onKeyboardClose() {

6. Changing the Emoji Keyboard colors to match your app theme

You can set three colors to the emojis keyboard by adding three parameters to the constructer which they are pressed tabs icons color, tabs color, and background color. 
We will use the same above constructer with the colors value.

EmojIconActions emojIcon= new EmojIconActions(this, rootView, emojiconEditText, emojiImageView,



7. Creating Sample App

Now we’ll create a simple app integrating the emojis to get a good understanding of it in a real app.

1. In Android Studio, go to File ⇒ New Project and fill all the details required to create a new project.

2. Open build.gradle and add supernova emoji library. You need to add its maven repository too.

repositories {
    maven { url "https://dl.bintray.com/hani-momanii/maven"}

dependencies {
    // Supernova Emoji
    compile 'hani.momanii.supernova_emoji_library:supernova-emoji-library:0.0.2'

3. Open the layout file your main activity activity_main.xml and add below code. Here you can see that I have added the emojiconEditText, emojiconTextView and the ImageView.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:src="@drawable/ic_insert_emoticon_black_24dp" />

        android:src="@android:drawable/ic_menu_send" />

        emojicon:emojiconSize="28sp" />

        android:text="Use System Default?" />

        android:text="Hello Emojis!"
        emojicon:emojiconUseSystemDefault="true" />

4. Now open MainActivity.java and make the changes as mentioned below. This activity show the different scenarios of implementing the SuperNova-Emoji as explained above.

package info.androidhive.emojis;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.ImageView;

import hani.momanii.supernova_emoji_library.Actions.EmojIconActions;
import hani.momanii.supernova_emoji_library.Helper.EmojiconEditText;
import hani.momanii.supernova_emoji_library.Helper.EmojiconTextView;

public class MainActivity extends AppCompatActivity {

    private static final String TAG = MainActivity.class.getSimpleName();
    CheckBox mCheckBox;
    EmojiconEditText emojiconEditText;
    EmojiconTextView textView;
    ImageView emojiImageView;
    ImageView submitButton;
    View rootView;
    EmojIconActions emojIcon;

    protected void onCreate(Bundle savedInstanceState) {
        rootView = findViewById(R.id.root_view);
        emojiImageView = (ImageView) findViewById(R.id.emoji_btn);
        submitButton = (ImageView) findViewById(R.id.submit_btn);
        mCheckBox = (CheckBox) findViewById(R.id.use_system_default);
        emojiconEditText = (EmojiconEditText) findViewById(R.id.emojicon_edit_text);
        textView = (EmojiconTextView) findViewById(R.id.textView);
        emojIcon = new EmojIconActions(this, rootView, emojiconEditText, emojiImageView);
        emojIcon.setIconsIds(R.drawable.ic_action_keyboard, R.drawable.smiley);
        emojIcon.setKeyboardListener(new EmojIconActions.KeyboardListener() {
            public void onKeyboardOpen() {
                Log.e(TAG, "Keyboard opened!");

            public void onKeyboardClose() {
                Log.e(TAG, "Keyboard closed");

        mCheckBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {


        submitButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                String newText = emojiconEditText.getText().toString();

Run And test the app.
