Remove the background of a textview

Question

I set a background for a textview and I want to remove it dynamically but it dosen't work, are there any suggestion?

if (mToday) {
        monthView[mRow][mColumn].setBackgroundResource(R.color.black);
    }
    else {
        monthView[mRow][mColumn].setBackgroundResource(0);
    }

I found a reasonable explanation here why it is happen, but again didn't solve the problem.

I checked all of the setbackgroundX methods but no one accept null! — Mahdak, Mar 02 '13 at 06:48
textView.setBackgroundDrawable(null); or android:background="@null" — Shiv, Mar 02 '13 at 07:08

You sure? because it normally helps, remember it has to be background**Resource** – Anders Metnik Oct 08 '14 at 07:57

try the following code just changed 0 to null in .setBackgroundDrawable thats all it will work check once :

 if (mToday)
 {
     monthView[mRow][mColumn].setBackgroundResource(R.color.black);
 }
else
 {
      monthView[mRow][mColumn].setBackgroundDrawable(null);
 }

I think this should work

monthView[mRow][mColumn].setBackgroundDrawable(null);
