android valueanimator for relativelayout with textview inside is laggy -


i trying animate changes of layout width. layout element i'm trying animate relativelayout. contains textview positioned rule align_parent_bottom. i'm creating code extending relativelayout viewgroup.

the following part of constructor: 

1    title = new textview(c); 2    layoutparams tvparams = new layoutparams(layoutparams.match_parent,                                               layoutparams.wrap_content); 3    tvparams.addrule(align_parent_bottom); 4    title.setlayoutparams(tvparams); 5    title.settext(this.feed.title); 6    this.addview(title);

and valueanimator: 

mscalex = valueanimator.ofint(mparamsoriginal.width, mparamslarge.width); mscalex.setinterpolator(new linearinterpolator()); mscalex.addupdatelistener(new valueanimator.animatorupdatelistener() {     @override     public void onanimationupdate(valueanimator valueanimator) {         int val = (integer) valueanimator.getanimatedvalue();         linearlayout.layoutparams layoutparams = (linearlayout.layoutparams) getlayoutparams();         layoutparams.width = val;         requestlayout();     } });

the thing comment rows 2-4 , put textview on layout works fine. otherwise profiler says causes constant re-measurement of view , device spends 90% of processor time on it.

so, there way solve issue?
