java - Why is setText not working? -


so have view made of single textview in middle , change text in textview according user's action, when use following code:

if(condition == 1){     maintext.settext("correct");     try {         wait(100);     } catch (interruptedexception e) {         e.printstacktrace();     }     random r = new random();     int idx = r.nextint(names.length);     random = (names[idx]);     maintext.settext(random);     condition = 0; }

the maintext doesn't change correct, change random.

any idea on how fix this, thanks

you can not use delays on ui thread, fail 100% of time.

set text, , post runnable ui thread delays desired time, , changes text.

view.settext("something"); view.postdelayed(new runnable(){     public void run(){         view.settext("somethingelse.");     } }, 200);
