java - How to get position of item selecte in gridview, or detect release of key with onItemClick? -

-

i must able detect press , release of button, must have position of item in gridview being touched. have gridview d-pad control. when user pushed on need send "go" , when release need send "stop"

with below , there no way tell when lift off button (that know!).

    grid.setadapter(new imageadapter(c, mthumbids));     grid.setonitemclicklistener(new onitemclicklistener() {         public void onitemclick(adapterview<?> parent, view v, int position, long id) {             message msg = new message();             msg.what = what;             msg.arg1 = position;             chandler.sendmessage(msg);         }     });

but if use ontouch listner cant tell item in grid have selected

grid.setontouchlistener(new ontouchlistener() {             public boolean ontouch(view v, motionevent event) {                 if (event.getaction() == motionevent.action_up) {                     message msg = new message();                     msg.what = 255;                     msg.arg1 = 255;                     chandler.sendmessage(msg);                 }                  if (event.getaction() == motionevent.action_down) {                         message msg = new message();                         msg.what = what;                         msg.arg1 = 55;                         chandler.sendmessage(msg);                 }                 return false;             }         });

your time appreciated !!

michael , have 2 choices such implementation

  • set onclicklistener on each of widgets in each grid item(eg.textview/imageview)

or

and you're done!
