android - How to use textview.getLayout()? It returns null -


i’m trying set layout textview can use getellipsiscount() method. below code returns null layout value. how can take layout , use getellipsiscount(0) method.

    public class mainactivity extends activity {   @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     textview mytextview =(textview) findviewbyid(r.id.textview1);     mytextview.settext(mytext);          layout layout = mytextview.getlayout();         if(layout != null){             mytextview.settext("very layout worked\n");         }  }

you calling early, thats why returning null

try this

  viewtreeobserver vto = mytextview.getviewtreeobserver();     vto.addongloballayoutlistener(new ongloballayoutlistener() {         @override         public void ongloballayout() {            layout layout = mytextview.getlayout();           }     });
