I put some ClickableSpan in EditText, unfortunately, that spans are still not clickable. When I click them, the only thing happened when I tap the clickablespan is the text cursor(selection, position, whatever you call it is) been set to that position.
After some search, I find out: I have to do this to make the span clickable?
setMovementMethod(LinkMovementMethod.getInstance());
After this, I do can click the ClickableSpan, but a new problem appear:
I can‘t do cursor selecting anymore, the cursor disappeared!
After a lot of searching and analyzing, I decide to make my own MovementMethod, which support both cursor selecting and span clicking. It‘s easy, the onTouchEvent() method is copied from android 1.5-r4 source code.
Here it goes:

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);
ClickableSpan[] link = buffer.getSpans(off, off, ClickableSpan.class);
if (link.length != 0) {
if (action == MotionEvent.ACTION_UP) {
link[0].onClick(widget);
} else if (action == MotionEvent.ACTION_DOWN) {
Selection.setSelection(buffer,
buffer.getSpanStart(link[0]),
buffer.getSpanEnd(link[0]));
}
return true;
} else {
Selection.removeSelection(buffer);
}
}
return super.onTouchEvent(widget, buffer, event);
}
@Override

return "my.handrite.text.method.ClickableArrowKeyMovementMethod";
}
public static MovementMethod getInstance() {
if (mInstance == null)
mInstance = new LinkArrowKeyMovementMethod();
return mInstance;
}
}
