public static String convertToMsg(CharSequence cs, Context mContext) {

SpannableStringBuilder ssb = new SpannableStringBuilder(cs);

 ImageSpan[] spans = ssb.getSpans(0, cs.length(), ImageSpan.class);

 for (int i = 0; i < spans.length; i++) {

ImageSpan span = spans[i];

 String c = span.getSource();

 int a = ssb.getSpanStart(span);

 int b = ssb.getSpanEnd(span);

 if (c.contains("[")) {

ssb.replace(a, b, convertUnicode(c));

 }

}

个人感觉 就是转码的问题.将获取到含有emoji表情的字符串进行下转换就可以了.当然发表emoji时候不需要做什么处理.仅仅服务端做出处理就可以.以utf-8字符串发表

ssb.clearSpans();

 return ssb.toString();

}

private static String convertUnicode(String emo) {

emo = emo.substring(1, emo.length() - 1);

 if (emo.length() < 6) {

return new String(Character.toChars(Integer.parseInt(emo, 16)));

 }

String[] emos = emo.split("_");

 char[] char0 = Character.toChars(Integer.parseInt(emos[0], 16));

 char[] char1 = Character.toChars(Integer.parseInt(emos[1], 16));

 char[] emoji = new char[char0.length + char1.length];

 for (int i = 0; i < char0.length; i++) {

emoji[i] = char0[i];

 }

for (int i = char0.length; i < emoji.length; i++) {

emoji[i] = char1[i - char0.length];

 }

return new String(emoji);

}
