You may use emoji4jlibrary.
您可以使用emoji4j库。
String text = "A , and a became friends??. For 's birthday party, they all had s, s, s and .";
EmojiUtils.shortCodify(text); //returns A :cat:, :dog: and a :mouse: became friends:heart:. For :dog:'s birthday party, they all had :hamburger:s, :fries:s, :cookie:s and :cake:.

Since that emoji is simply a standard Unicode code point (U+1F601, see here), probably the best way is to set up a map which translates them into strings.
由于该表情符号只是一个标准的 Unicode 代码点（U+1F601，请参见此处），因此最好的方法可能是设置一个将它们转换为字符串的映射。
By way of example, here's a piece of code that creates a string-to-string map to allow you to look up and translate that exact code point:
举例来说，这里有一段代码，它创建了一个字符串到字符串的映射，以允许您查找和翻译那个确切的代码点：
import java.util.HashMap;
import java.util.Map;
class Xyzzy {
public static Map<String,String> xlat = new HashMap<String, String>();
public static void main (String[] args) {
xlat.put("\uD83D\uDE01", "happy");
System.out.println(xlat.get("\uD83D\uDE01"));
}
}
You can add as many code points to the map as you wish, and use Map.get()to extract the equivalent text for any of them.
您可以根据需要向地图添加任意数量的代码点，并用于Map.get()提取其中任何一个的等效文本。
