如何将表情符号有意发送到whatsapp？

Question

我知道我们可以通过以下意图向 whatsapp 发送纯文本：

 Intent sendIntent = new Intent();
 sendIntent.setAction(Intent.ACTION_SEND);
 sendIntent.putExtra(Intent.EXTRA_TEXT,"Text to be sent on whatsapp");
 sendIntent.setType("text/plain");
 sendIntent.setPackage("com.whatsapp");
 startActivity(sendIntent);

但我希望能够通过意图将表情符号（表情符号）发送到 whatsapp。
怎么可能？ 我们有一些特殊的表情符号代码吗？

Answer 1

我为此使用了 StringBuilder，例如：

int unicode = 0x1F600
StringBuilder s = new StringBuilder();
s.append("YOUR MESSAGE HERE");
s.append(Character.toChars(unicode));

结果字符串将是这样的

你的留言在这里😀

从这里复制 unicode 但请记住将您将从该网页复制的代码从 U-1F600 更改为 0x1F600。

U-1F600 是 unicode，但 android 无法识别。 0x1F600 是 android 的十六进制代码。

Answer 2

使用它而不是使用StringBuilder

 // send message with emojis
       int waveEmojiUnicode = 0x1F44B,
           clapEmojiUnicode = 0x1F44F,
           faceTongueEmojiUnicode = 0x1F60B;
        
            char[] waveEmojiChars = Character.toChars(waveEmojiUnicode);
            char[] clapEmojiChars = Character.toChars(clapEmojiUnicode);
            char[] faceTongueEmojiChars = Character.toChars(faceTongueEmojiUnicode);
        
            String s1 = "Hi Noah ", s2 = ", TimeLY is a nice app ", s3 = ". However, I would like" + " to report a bug [ ... ]. My name is [ ... ] by the way.";
        
            String message = s1 + String.valueOf(waveEmojiChars) + s2 + String.valueOf(clapEmojiChars) + s3 + String.valueOf(faceTongueEmojiChars);

     Intent sendIntent = new Intent();
     sendIntent.setAction(Intent.ACTION_SEND);
     sendIntent.putExtra(Intent.EXTRA_TEXT, message);
     sendIntent.setType("text/plain");
     sendIntent.setPackage("com.whatsapp");
     startActivity(sendIntent);
