问题描述
我想查找用户输入到EditText

I would like to find how many emojis the user has input into an EditText
. If the user only enters emojis, and uses 3 or less, I want to be able to display that string within the app with a larger font.
现在我确实碰到了这篇文章,它确实有助于检测字符串中是否存在表情符号,但是我还无法弄清楚如何计算表情符号的数量.
Right now I did come across this post which does help detect if emojis are present in the string, but I have not been able to figure out how to count the number of emojis.
有人知道我如何从字符串中获取表情符号计数吗?
Does anyone know how I can get the emoji count from a String?
推荐答案
int emojiCount = 0;
for (int i = 0; i < yourString.length(); i++) {
int type = Character.getType(yourString.charAt(i));
if (type == Character.SURROGATE || type == Character.OTHER_SYMBOL) {
emojiCount++;
}
}
return emojiCount/2;
