Click event of the specific character from ImageSpan

Question

I am using ImageSpan to display the textview as a bitmap using SpannableStringBuilder.

I have successfully implemented it and got the following output.

Now i want the click event of the specific character of the textview i.e of Cross Sign from the textview.

For that i have referred this demo.

But this returns me the click event of the whole textview.I want the click event of the only Cross Sign which is at the end of the textview.

What i have tried so far ::

final TextView tv = createMultiSelectTextView(selectValue[i]);
BitmapDrawable bd = (BitmapDrawable) convertViewToDrawable(tv);
bd.setBounds(0, 0, bd.getIntrinsicWidth(),bd.getIntrinsicHeight());

spannableStringBuilder.append(selectValue[i]+" ");
spannableStringBuilder.setSpan(new ImageSpan(bd), spannableStringBuilder.length()-(selectValue[i].length()+1), spannableStringBuilder.length()-1,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

ClickableSpan clickSpan = new ClickableSpan() {
        @Override
        public void onClick(View view) {    
        }};
        spannableStringBuilder.setSpan(clickSpan,spannableStringBuilder.length()-(selectValue[i].length()+1), spannableStringBuilder.length()-1,
        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    }


if (spannableStringBuilder.length() > 0) {
    button.setText(spannableStringBuilder);

    button.setMovementMethod(LinkMovementMethodExt
                    .getInstance(handler, ClickableSpan.class));

} else {
    button.setText(context.getString(R.string.msg_select)
                    + select.getFieldName());

    button.setMovementMethod(LinkMovementMethodExt
                    .getInstance(handler, ClickableSpan.class));
}

Handle the response in Handler ::

private Handler handler = new Handler() {
        public void handleMessage(Message msg) {
            int what = msg.what;
            BackgroundColorSpan color = null;
            if (what == 100) {
                MessageSpan ms = (MessageSpan) msg.obj;
                Object[] spans = (Object[])ms.getObj();
                TextView view = ms.getView();

                for (Object span : spans) {
                    if (span instanceof ClickableSpan) {
                        int start = Selection.getSelectionStart(view.getText());
                        int end = Selection.getSelectionEnd(view.getText());
                        Spannable _span = (Spannable)view.getText();
                        System.out.println("Cross Clicked 123456!!!");
                        color = new BackgroundColorSpan(view.getLinkTextColors().getDefaultColor());
                        _span.setSpan(color, start, end, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
                        view.setText(_span);
                    }
                }
            }else if (what == 200) {
                MessageSpan ms = (MessageSpan) msg.obj;
                TextView view = ms.getView();
                Spannable _span = (Spannable)view.getText();
                _span.removeSpan(color);
                view.setText(_span);
            }
        };
