9 years ago I solved this problem, just add these code in the bottom of EmojiconHandler.java
public static int calculateTextLength(Context context, Spannable text, int index, int length, boolean useSystemDefault) { if (useSystemDefault) { return 0; }
int textCount = 0;
int textLength = text.length();
int textLengthToProcessMax = textLength - index;
int textLengthToProcess = length < 0 || length >= textLengthToProcessMax ? textLength : (length+index);
// remove spans throughout all text
EmojiconSpan[] oldSpans = text.getSpans(0, textLength, EmojiconSpan.class);
for (int i = 0; i < oldSpans.length; i++) {
text.removeSpan(oldSpans[i]);
}
int skip;
for (int i = index; i < textLengthToProcess; i += skip) {
textCount++;
skip = 0;
int icon = 0;
char c = text.charAt(i);
if (isSoftBankEmoji(c)) {
icon = getSoftbankEmojiResource(c);
skip = icon == 0 ? 0 : 1;
}
if (icon == 0) {
int unicode = Character.codePointAt(text, i);
skip = Character.charCount(unicode);
if (unicode > 0xff) {
icon = getEmojiResource(context, unicode);
}
if (icon == 0 && i + skip < textLengthToProcess) {
int followUnicode = Character.codePointAt(text, i + skip);
if (followUnicode == 0x20e3) {
int followSkip = Character.charCount(followUnicode);
switch (unicode) {
case 0x0031:
icon = R.drawable.emoji_0031;
break;
case 0x0032:
icon = R.drawable.emoji_0032;
break;
case 0x0033:
icon = R.drawable.emoji_0033;
break;
case 0x0034:
icon = R.drawable.emoji_0034;
break;
case 0x0035:
icon = R.drawable.emoji_0035;
break;
case 0x0036:
icon = R.drawable.emoji_0036;
break;
case 0x0037:
icon = R.drawable.emoji_0037;
break;
case 0x0038:
icon = R.drawable.emoji_0038;
break;
case 0x0039:
icon = R.drawable.emoji_0039;
break;
case 0x0030:
icon = R.drawable.emoji_0030;
break;
case 0x0023:
icon = R.drawable.emoji_0023;
break;
default:
followSkip = 0;
break;
}
skip += followSkip;
} else {
int followSkip = Character.charCount(followUnicode);
switch (unicode) {
case 0x1f1ef:
icon = (followUnicode == 0x1f1f5) ? R.drawable.emoji_1f1ef_1f1f5 : 0;
break;
case 0x1f1fa:
icon = (followUnicode == 0x1f1f8) ? R.drawable.emoji_1f1fa_1f1f8 : 0;
break;
case 0x1f1eb:
icon = (followUnicode == 0x1f1f7) ? R.drawable.emoji_1f1eb_1f1f7 : 0;
break;
case 0x1f1e9:
icon = (followUnicode == 0x1f1ea) ? R.drawable.emoji_1f1e9_1f1ea : 0;
break;
case 0x1f1ee:
icon = (followUnicode == 0x1f1f9) ? R.drawable.emoji_1f1ee_1f1f9 : 0;
break;
case 0x1f1ec:
icon = (followUnicode == 0x1f1e7) ? R.drawable.emoji_1f1ec_1f1e7 : 0;
break;
case 0x1f1ea:
icon = (followUnicode == 0x1f1f8) ? R.drawable.emoji_1f1ea_1f1f8 : 0;
break;
case 0x1f1f7:
icon = (followUnicode == 0x1f1fa) ? R.drawable.emoji_1f1f7_1f1fa : 0;
break;
case 0x1f1e8:
icon = (followUnicode == 0x1f1f3) ? R.drawable.emoji_1f1e8_1f1f3 : 0;
break;
case 0x1f1f0:
icon = (followUnicode == 0x1f1f7) ? R.drawable.emoji_1f1f0_1f1f7 : 0;
break;
default:
followSkip = 0;
break;
}
skip += followSkip;
}
}
}
}
return textCount;
}To call it, int textLength = EmojiconHandler.calculateTextLength(getActivity(), new SpannableStringBuilder(text), 0, -1, false);
Is there any way to calculate the appearance of emojicon in EmojiconTextView accurately? Such as 😎😎😎 is consider as 3 characters.
Thanks in advance for willing to help.
