Android: onTouch for Spans in Spannable Text

I have a TextView containing Editable text. There are pictures in this text (drawables, I used Html.ImageGetter) for that I want to register onTou开发者_如何学Goch events. So, when the user touches the image, which is part of a spannable text, I want to know that. (And, which image he touched).

Is that possible? If so, maybe without dirty workarounds?

Best regards, Jan Oliver Oelerich

Copied from the ArrowKeyMovementMethod source code, you could try to use the following snippet of code:

 private int getOffset(int x, int y, TextView widget){
  // Converts the absolute X,Y coordinates to the character offset for the
  // character whose position is closest to the specified
  // horizontal position.
  x -= widget.getTotalPaddingLeft();
  y -= widget.getTotalPaddingTop();

  // Clamp the position to inside of the view.
  if (x < 0) {
      x = 0;
  } else if (x >= (widget.getWidth()-widget.getTotalPaddingRight())) {
      x = widget.getWidth()-widget.getTotalPaddingRight() - 1;
  }
  if (y < 0) {
      y = 0;
  } else if (y >= (widget.getHeight()-widget.getTotalPaddingBottom())) {
      y = widget.getHeight()-widget.getTotalPaddingBottom() - 1;
  }

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

  Layout layout = widget.getLayout();
  int line = layout.getLineForVertical(y);

  int offset = layout.getOffsetForHorizontal(line, x);
  return offset;
}

Hope that helps, EdenSphere.
