Question

I have a function to build clickable tags for a textview. It goes as follows:

    private CharSequence tagsBuilder(String text, String token) {
    SpannableStringBuilder builtTags = new SpannableStringBuilder();
    int start = 0, end = 0;

    for(int i = 0; i < 5; i++) {
        start = 0;
        end = text.indexOf(token, 0);

        try {
            if(start < end) {
                SpannableStringBuilder ssb = new SpannableStringBuilder(text.substring(start, end));
                ssb.setSpan(new ClickableSpan() {
                    @Override
                    public void onClick(View v)
                    {

                        Log.i("DEBUGTAG", "Span clicked - " + ((TextView) v).getText());
                    }
                }, start, end, 0);

                builtTags.append(ssb);
                builtTags.append(" ");
                text = text.substring(end + 1);
            }
        } catch (IndexOutOfBoundsException e) {
            break;
        }
    }

    return builtTags;
}

I can see the textview with 5 individually clickable tags. But the problem is, the Log that prints for any tag that is clicked is whole text of the textview.

Am I doing something wrong here? How do I get the text of individual tags that were clicked.

Your log line is the following:

Log.i("DEBUGTAG", "Span clicked - " + ((TextView) v).getText());

That logs the contents of the TextView. So… you get the text of the TextView. If you want to get token in there, you’ll have to copy that in.

Here’s something you can try:

private CharSequence tagsBuilder(String text, final String token) {
SpannableStringBuilder builtTags = new SpannableStringBuilder();
int start = 0, end = 0;

for(int i = 0; i < 5; i++) {
    start = 0;
    end = text.indexOf(token, 0);

    try {
        if(start < end) {
            SpannableStringBuilder ssb = new SpannableStringBuilder(text.substring(start, end));
            ssb.setSpan(new ClickableSpan() {
                private String mText = token;
                @Override
                public void onClick(View v)
                {

                    Log.i("DEBUGTAG", "Span clicked - " + mText);
                }
            }, start, end, 0);

            builtTags.append(ssb);
            builtTags.append(" ");
            text = text.substring(end + 1);
        }
    } catch (IndexOutOfBoundsException e) {
        break;
    }
}

return builtTags;
}
