java - Programatically setting TextView background -


i've defined background textview:

<?xml version="1.0" encoding="utf-8"?> <shape     xmlns:android="http://schemas.android.com/apk/res/android"     android:shape= "rectangle"  >     <solid android:color="#000"/>     <stroke android:width="1dp"  android:color="#ff9"/> </shape>

now i'm trying set textview programmatically:

textview.setbackground((drawable)findviewbyid(r.drawable.cellborder));

this isn't working though, it's telling me can't cast view drawable. there way this?

you have use

getresources().getdrawable(r.drawable.cellborder);

which return drawable.

if use findviewbyid() try find view in view hierarchy , return that. view not drawable, can't cast it.
