java - How to cancel the execution of postDelayed() -

i'm making app sort of widgets created on fly , can re-arranged drag , drop. i'm trying implement 2 things:

1. long press initiate drag , drop
2. short press(or click) open menu change settings.

but i'm having problem can't cancel code in handler's postdelayed() function. i'm using following code make happen.

      _sliders_item[_sliders_counter].setontouchlistener(new view.ontouchlistener() {             @override             public boolean ontouch(final view v, motionevent event) {                 handler hndlr = new handler();                 runnable _run = new runnable() {                     @override                     public void run() {                         clipdata data = clipdata.newplaintext("", "");                         view.dragshadowbuilder shadowbuilder = new view.dragshadowbuilder(v);                         v.startdrag(data, shadowbuilder, v, 0);                         v.setvisibility(view.invisible);                         _t1.settext("executed");                         _t1.show();                     }                 };                 if (_enable_editor) {                     if (event.getaction() == motionevent.action_down) {                         hndlr.postdelayed(_run,1000);                         //return true;                     }                     if (event.getaction() == motionevent.action_up){                         _t1.settext("menu");                         _t1.show();                         hndlr.removecallbacks(_run);                         //return true;                     }                 }                 return _enable_editor;             }         }); 

but problem is, when long press object, works fine. can initiate drag , drop. when short press it, code action_up event executes code inside runnable still executes. how can cancel runnable code when short press object?

you have keep references runnables , handler , use handler#removecallbacks().

so basically:

handler h = new handler(); runnable r = new runnable() { /* */ h.postdelayed(r, 1000);  // when want cancel. h.removecallbacks(r);
