A simple library to add Emoji support to your Android Application

Emoji

A simple library to add Emoji support to your Android app. In a PopupWindow Emojis can be chosen. In order to edit and display text with Emojis this library provides public APIs: EmojiEditText, EmojiTextView & EmojiButton.

The library has 3 different providers to choose from (iOS, Google & Twitter).

iOS Emojis

For getting the above iOS Emojis simply add the dependency and code below.

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

And install the provider (preferably in your Application class):

// This line needs to be executed before any usage of EmojiTextView, EmojiEditText or EmojiButton.
EmojiManager.install(new IosEmojiProvider());

Google

For getting the above Google Emojis simply add the dependency and code below.

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

And install the provider (preferably in your Application class):

// This line needs to be executed before any usage of EmojiTextView, EmojiEditText or EmojiButton.
EmojiManager.install(new GoogleEmojiProvider());

Twitter

For getting the above Twitter Emojis simply add the dependency and code below.

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

And install the provider (preferably in your Application class):

// This line needs to be executed before any usage of EmojiTextView, EmojiEditText or EmojiButton.
EmojiManager.install(new TwitterEmojiProvider());

Custom Emojis

If you want to display your own Emojis you can create your own implementation of EmojiProvider and pass it to EmojiManager.install.

All of the core API lays in, which is being pulled in automatically by the provided implementations (iOS, Google & Twitter):

implementation 'com.vanniktech:emoji:0.6.0'

Custom EditText

If you want to add the emoji support to your existing EditText, you only have to call EmojiManager.getInstance().replaceWithImages inside onTextChanged. An example can be seen on the default EditText implementation: EmojiEditText.

Inserting Emojis

Declare your EmojiEditText in your layout xml file.

<com.vanniktech.emoji.EmojiEditText
  android:id="@+id/emojiEditText"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:imeOptions="actionSend"
  android:inputType="textCapSentences|textMultiLine"
  android:maxLines="3"/>

To open the EmojiPopup execute the code below:

final EmojiPopup emojiPopup = EmojiPopup.Builder.fromRootView(rootView).build(emojiEditText);
emojiPopup.toggle(); // Toggles visibility of the Popup.
emojiPopup.dismiss(); // Dismisses the Popup.
emojiPopup.isShowing(); // Returns true when Popup is showing.

The rootView is the rootView of your layout xml file which will be used for calculating the height of the keyboard. emojiEditText is the EmojiEditText that you declared in your layout xml file.

Note: Instantiate the EmojiPopup as early as possible in the lifecycle (e.g. in onCreate of your Activity or onViewCreated in your Fragment), otherwise the keyboard detection might not work as expected.

Displaying Emojis

<com.vanniktech.emoji.EmojiTextView
  android:id="@+id/emojiTextView"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"/>

Just use the EmojiTextView and call setText with the String that contains Unicode encoded Emojis. To change the size of the displayed Emojis use the lineHeight property from TextView.

Listeners

The EmojiPopup builder allows you to declare several listeners.

setOnSoftKeyboardCloseListener(OnSoftKeyboardCloseListener listener);
setOnEmojiClickListener(OnEmojiClickListener listener);
setOnSoftKeyboardOpenListener(OnSoftKeyboardOpenListener listener);
setOnEmojiPopupShownListener(OnEmojiPopupShownListener listener);
setOnEmojiPopupDismissListener(OnEmojiPopupDismissListener listener);
setOnEmojiBackspaceClickListener(OnEmojiBackspaceClickListener listener);

Custom Recent Emoji implementation

You can pass your own implementation of the recent Emojis. Just let one of your classes implement the RecentEmoji interface and pass it when you're building the EmojiPopup:

setRecentEmoji(yourClassThatImplementsRecentEmoji)

If no instance or a null instance is set the default implementation will be used.

Custom Variant Emoji implementation

You can pass your own implementation of the variant Emojis. Just let one of your classes implement the VariantEmoji interface and pass it when you're building the EmojiPopup:

setVariantEmoji(yourClassThatImplementsVariantEmoji)

If no instance or a null instance is set the default implementation will be used.

Animations

Custom keyboard enter and exit animations

You can pass your own animation style for enter and exit transitions of the Emoji keyboard while you're building the EmojiPopup:

setKeyboardAnimationStyle(R.style.emoji_fade_animation_style);

If no style is set the keyboard will appear and exit as a regular PopupWindow. This library currently ships with two animation styles as an example:

• R.style.emoji_slide_animation_style
• R.style.emoji_fade_animation_style

Custom page transformers

You can pass your own Page Transformer for the Emoji keyboard View Pager while you're building the EmojiPopup:

setPageTransformer(new MagicTransformer());

If no transformer is set ViewPager will behave as its usual self. Please do note that this library currently does not ship any example Page Transformers.

Snapshots

This library is also distributed as a SNAPSHOT if you like to check out the latest features.

Note: The API is not stable and may change and break your code at any time if you use a SNAPSHOT.

Add this to your repositories:

maven { url "https://oss.sonatype.org/content/repositories/snapshots" }

And one of these to your dependencies:

implementation 'com.vanniktech:emoji-ios:0.7.0-SNAPSHOT'
implementation 'com.vanniktech:emoji-google:0.7.0-SNAPSHOT'
implementation 'com.vanniktech:emoji-twitter:0.7.0-SNAPSHOT'
