Answer 1

You don't need a library for this.

Method 1

Suppose you have a textview, then try this

textView.setText(new String(Character.toChars(0x1F60A)));

where 0x1F60A is the unicode for your smiley

Alternate Method

add this resource in strings.xml

<string name="smiley_text">&#x1F60A;</string>

then add it to textview like below

textview.setText(R.string.smiley_text);

Answer 2

• Check this library https://github.com/vanniktech/Emoji

  implementation 'com.vanniktech:emoji-ios:0.5.1'
  

• Add this line to onCreate inside Application class.

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

• Then use EmojiEditText & EmojiTextView

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

Update

• Use EmojiCompat

  • Open the build.gradle file of your application.

  • Add the support library to the dependencies section.

    dependencies {
          ...
         compile "com.android.support:support-emoji:27.1.1"
    }
    

  • Use EmojiCompat widgets in layout XMLs. If you are using AppCompat, refer to the Using EmojiCompat widgets with AppCompat section.

    <android.support.text.emoji.widget.EmojiTextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"/>
    

Update 2

• For predefined emojis you can use unicode emojis, as Navneet Krishna answer.
