android - Dynamic image with variable as a name -

i trying display image when have variable array (arr[r1]) matches name of picture. tried using didnt work:

imageview imageview = (imageview)findviewbyid(r.id.imageview); imageview.setimagedrawable(getresources().getdrawable(getresources().getidentifier("drawable/"+arr[r1], "drawable", getpackagename())));

any thought doing wrong?
