how to get the source of ImageView in order to change it?

Question

I know that changing the ImageView resource is not big deal just using myImageView.setImageResource(mynewImageDrawable)

but what I want to do is to chec

Answer 1

Actualy after my try ,I find there is a way to get source of imageView without need of tag property.

Integer src = attrs.getAttributeResourceValue(
                    "http://schemas.android.com/apk/res/android", "src", -1);

The first parameter is namespace of android and src is the property name. This method return the image resource id if it found or it will return -1;
