ClickableSpan strange behavior:onClick() called when clicking empty space

Question

I have a TextView with ClickableSpan in that both layout_height and layout_width is wrap_content.

When the text in TextView in

Answer 1

I managed to solve it by extending LinkMovementMethod, and check whether the touch event offset is equals or bigger than the text lenght:

public class MovementMethod extends LinkMovementMethod {

    @Override
    public boolean onTouchEvent(TextView widget, Spannable buffer, MotionEvent event) {
        int action = event.getAction();

        if (action == MotionEvent.ACTION_UP || action == MotionEvent.ACTION_DOWN) {
            int x = (int) event.getX();
            int y = (int) event.getY();

            x -= widget.getTotalPaddingLeft();
            y -= widget.getTotalPaddingTop();

            x += widget.getScrollX();
            y += widget.getScrollY();

            Layout layout = widget.getLayout();
            int line = layout.getLineForVertical(y);
            int off = layout.getOffsetForHorizontal(line, x);

            if (off >= widget.getText().length()) {
               // Return true so click won't be triggered in the leftover empty space
                return true;
            }
        }

        return super.onTouchEvent(widget, buffer, event);
    }
}

Thanks for @dor506 for the answer, but it not work for gravity center, I have modified a little bit.

@Override
        public boolean onTouchEvent(TextView widget, Spannable buffer, MotionEvent event) {
            int action = event.getAction();

            if (action == MotionEvent.ACTION_UP) {
                int x = (int) event.getX();
                int y = (int) event.getY();

                y -= widget.getTotalPaddingTop();
                y += widget.getScrollY();

                Layout layout = widget.getLayout();
                int line = layout.getLineForVertical(y);
                float lineLeft = layout.getLineLeft(line);
                float lineRight = layout.getLineRight(line);

                if (x > lineRight || (x >= 0 && x < lineLeft)) {
                    return true;
                }
            }

            return super.onTouchEvent(widget, buffer, event);
        }
