how to setImage to null in android when the xml has src not null?

Question

I have this xml

<ImageView
    android:id="@+id/ImgOn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:src="@drawable/icon_on" />

I want to remove this image sometimes via code. I've seen many posts like this, but in my case imageButton.setBackgroundResource(0); leaves the default image which appears in my xml layout.

How would you remove it programmatically? I heard transparent color crashes some old devices.

update

setImageResource(0) left the xml's original src as well and not null as i want it to be

did you try `imageView.setImageDrawable(null);`? – Shayan Pourvatan Apr 02 '14 at 09:37 — Shayan Pourvatan, Apr 02 '14 at 09:37

Try this..

Your setting setBackgroundResource that's for android:background="@drawable/icon_on" not for android:src="@drawable/icon_on" background and src both are different use

imageButton.setImageResource(0);

EDIT

imageButton.setImageDrawable(null);

The background (backgroundresource) and foreground (src) image are two different things, thus the one does not influence the other.

Remove the foreground image using:

imageButton.setImageDrawable(null);
