setImageResource(0) left the original xml src, and not null as i want it to

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.setImageResource(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.

Answer 1

you can use imageView.setImageDrawable(null);
