Java/Android: Handler and a for loop to show some elements of an array -


i have array buttons (10 buttons )

and want show these buttons delay using handler

but problem don't want show buttons !

i mean , saved buttons using sharedpreferences , buttons invisible in loop.

so here's thing , how can use handler.postdelayed

to show buttons aren't saved invisible ?

here's example:

    button btn1 = (button)findviewbyid(r.id.btn1);     button btn2 = (button)findviewbyid(r.id.btn2);     button btn3 = (button)findviewbyid(r.id.btn3);     button btn4 = (button)findviewbyid(r.id.btn4);     button btn5 = (button)findviewbyid(r.id.btn5);  // buttons array         button mybtns[] = new button[]{btn1, btn2 , btn3 , btn4 , btn5};      // handler myhandler = new handler();      (int x=0; x<mybtns.length; x++)     {         if (!mysharedpreforsavedbtns.getboolean(mybtns[x].getid()+"",false))         {              myhandler.postdelayed(new runnable() {            public void run() {  // how can show buttons 1 one ???                         mybtns[x].setvisibility(view.visible);                      }                  }, 500 * x);              }         }

now how can show buttons 1 one ???

 (int x = 0; x < mybtns.length; x++){         final int finalx = x;         new handler().postdelayed(new runnable() {             @override             public void run() {                  mybtns[finalx].setvisibility(view.visible);             }         }, 500*x);  }

or can use 

handler uithreadhandler  = new handler();     showdelayed(btn1, delaytime);     showdelayed(btn2, delaytime);    public void showdelayed(final view v, int delay){     uithreadhandler.postdelayed(new runnable() {         @override         public void run() {             v.setvisibility(view.visible);         }     }, delay); }

hope work
