touch - Android: How identify an ImageView by Tag or ID -


i have on activity several imageview's user can move around screen. how can identify imageview selected user? in xcode can assign unique tag each imageview , ontouch tag number. there similar way on android?

this xcode:

uitouch *touch = [[event alltouches] anyobject];  if ([touch view].tag == 901) {     itouchobject = 901;         [self.view bringsubviewtofront:imgrojo1]; }

in android activity have far done: in oncreate can assign id each imageview

    imageview selimage = (imageview)findviewbyid(r.id.i904);      selimage.setid(904);

and in ontouch.moved can use imageview directly assigned id. in case image moves smooth below finger on screen.

    iid = 904;     imageview selimage = (imageview)findviewbyid(iid);

but, how can id imageview user has touched?

i have tried use setontouchlistener:

    imageview selimage = (imageview)findviewbyid(r.id.i904);      selimage.setid(904);     selimage.setontouchlistener(new view.ontouchlistener() {                   @override         public boolean ontouch(view v, motionevent event) {         iid = v.getid();         imageview selimage = (imageview)findviewbyid(iid);           int eventaction = event.getaction();              int x = (int)event.getx();         int y = (int)event.gety();         switch (eventaction ) {         case motionevent.action_down: // touch down check if finger on ball                 break;          case motionevent.action_move:   // touch drag ball                  // move balls same finger               selimage.setx(x-25);              selimage.sety(y-25);              break;         case motionevent.action_up:                  // touch drop - things here after dropping              break;         }         // redraw canvas         return true;      }});

by can select each imageview , moves, but, doesn't move smooth , imageview duplicated on screen.

is possible in first case in ontouch.moved view , use id with: iid = v.getid();

you can check id current view has , compare actual resource id.

for example:

switch (v.getid()) { case r.id.image1:     //     break; case r.id.image2:     // ..     break; case r.id.image3:     // ..     break; }
