try code.. set image view width , height run time.
private void setimageview() { // adding view tree observer on image container yourlayout.getviewtreeobserver().addonpredrawlistener(new viewtreeobserver.onpredrawlistener() { @override public boolean onpredraw() { // remove predrawlistener yourlayout.getviewtreeobserver().removeonpredrawlistener(this); setimageviewparams(); return true; } }); yourimageview.getviewtreeobserver().addonpredrawlistener(new viewtreeobserver .onpredrawlistener() { @override public boolean onpredraw() { // remove predrawlistener yourimageview.getviewtreeobserver().removeonpredrawlistener(this); setimageviewparams(); return true; } }); } private void setimageviewparams() { if (yourimageview.getheight() == 0 || rootview.getheight() == 0) { return; } linearlayout.layoutparams layoutparams = (linearlayout.layoutparams) rootview.getlayoutparams(); int imageviewpostion = (rootview.getwidth()/2); linearlayout.layoutparams imageviewlayoutparams = (linear.layoutparams) yourimageview.getlayoutparams(); imageviewlayoutparams.setwidth = positonafterimagecontainer; iamgeviewlayoutparams.setheight = positonafterimagecontainer; imageviewid.setlayoutparams(imageviewlayoutparams); }
