Andrey :
Let´s say I make a comment like this:
Hi Andrea check this out..... In that comment I want to highlight Andrea, but whenever I change the value of Andrea or when I delete one character of the word the span changes, the problem is that I´m using spannableString.setSpan(new StyleSpan(Typeface.BOLD), indexOfAt, highlightName.length() + indexOfAt, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE), which Spanned.SPAN_EXCLUSIVE_EXCLUSIVE accepts words in the middle and deletion of words, how can I remove the span when the user changes the word or delete a character of the word?

You need to watch for Text change on the edit text.
Assuming the EditText, you are using is named as commentEditText
commentEditText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void afterTextChanged(Editable editable) {
String comment = editable.toString();
if (comment.indexOf('@') != -1) {
//Asumming the name string
String name = "Andrea";
int atIndex = comment.indexOf('@');
int endIndex = atIndex + name.length() + 1;
if (endIndex == -1 || endIndex > editable.length()) {
endIndex = editable.length();
}
if (comment.toLowerCase().contains(name.toLowerCase())) {
editable.setSpan(new StyleSpan(Typeface.BOLD), atIndex, endIndex, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
} else {
StyleSpan[] spannable = editable.getSpans(atIndex, endIndex, StyleSpan.class);
if (spannable != null && spannable.length > 0) {
for (int i = 0; i < spannable.length; i++) {
editable.removeSpan(spannable[i]);
}
}
}
}
}
});
