Clickable moving buttons in android -


i'm trying create app in android spawn button @ top of screen random x-possition, have move downwards @ constant pace , when click disappear, i'm confident in abilities of myself 1 problem can't seem work around want able click button time while moving, i've found how change possition of button still fixed while want follow visual button. not sure if i'm saying makes sense if so, if me out appreciated! in advance

public void animate() {     starbutton.startanimation(anim);     long start = system.currenttimemillis();     boolean bool = true;     int = 0;     while(bool) {         long cur = system.currenttimemillis();         if(cur - start >= 50) {             float postogo = starbutton.gety() + 20;             starbutton.sety(postogo);             i++;             start = system.currenttimemillis();             if(i > 40) {                 bool = false;             }         }     } }

don't use old animation api, use new 1 objectanimators , stuff. check out tutorial : http://www.vogella.com/tutorials/androidanimation/article.html

edit: clarification...the old api didn't move anything, drawing image of view @ different position, view never changed position, new 1 changes position , other properties.
