Question

I have a Handler how can i know when the postdelayed method has been completed.

    new Handler().postDelayed(new Runnable(){
        public void run() {
            ll.setEnabled(false);
        } 
    }, 3000);

I think you can always write one flag/toast/log in that run() method like,

Handler handler = new Handler();
handler.postDelayed(new Runnable(){ 
            public void run() { 
                ll.setEnabled(false); 
                handler.postDelayed(afterExe,0);
            }  
        }, 3000);   

Runnable afterExe = new Runnable()
{
   public void run()
   {
           //code to next step
   }
}

Sorry If i didn’t get you correctly.
