You can add tag to ImageView,

Set a tag either in xml or dynamically In xml:

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/imageview" 
    android:background="@drawable/drawable_name"
    android:tag="drawable_name"/>

Dynamically,

ImageView imageView=(ImageView)findViewById(R.id.imageview);
imageView.setTag("bg");

Use imageView.getTag() to retrieve image information.

String backgroundImageName = String.valueOf(imageView.getTag()); 

you can set tag when you change your drawable and get it by this method
