java - Android Multitouch - Second Finger ACTION.MOVE Ignored -

the next code i've been trying utilize multitouch. finger 1 set correctly , moves around when drag finger. finger 2 shows , disappears when touch , release finger, never moves around. thought what's wrong?

i have read developers blog still not understand issues are.

@override public boolean ontouchevent(motionevent event) { int action = event.getaction() & motionevent.action_mask; int pointerindex = (event.getaction() & motionevent.action_pointer_id_mask) >> motionevent.action_pointer_id_shift; int pointerid = event.getpointerid(pointerindex); switch (action) { case motionevent.action_down: case motionevent.action_pointer_down: if (pointerid == 0) { fingeronedown = 1; fingeronex = event.getx(pointerindex); fingeroney = event.gety(pointerindex); } if (pointerid == 1) { fingertwodown = 1; fingertwox = event.getx(pointerindex); fingertwoy = event.gety(pointerindex); } break; case motionevent.action_up: case motionevent.action_pointer_up: case motionevent.action_cancel: if (pointerid == 0) { fingeronedown = 0; fingeronex = event.getx(pointerindex); fingeroney = event.gety(pointerindex); } if (pointerid == 1) { fingertwodown = 0; fingertwox = event.getx(pointerindex); fingertwoy = event.gety(pointerindex); } break; case motionevent.action_move: if (pointerid == 0) { fingeronedown = 1; fingeronex = event.getx(pointerindex); fingeroney = event.gety(pointerindex); } if (pointerid == 1) { fingertwodown = 1; fingertwox = event.getx(pointerindex); fingertwoy = event.gety(pointerindex); } break; } homecoming true; }

nevermind this. fixed it. action.move event gets 0 pointerid unusual reason. because of this, have recalculate pointerid within event seen below:

case motionevent.action_move: int pointercount = event.getpointercount(); for(int = 0; < pointercount; ++i) { pointerindex = i; pointerid = event.getpointerid(pointerindex); log.d("pointer id - move",integer.tostring(pointerid)); if(pointerid == 0) { fingeronedown = 1; fingeronex = event.getx(pointerindex); fingeroney = event.gety(pointerindex); } if(pointerid == 1) { fingertwodown = 1; fingertwox = event.getx(pointerindex); fingertwoy = event.gety(pointerindex); } } break;

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
