Is there any way to get the Drawable resource ID? For example, I am using an ImageView and I may initially use icon.png as its image but later I may change the image to icon2.png. I want to find out using the code that which image my ImageView is using from the resource. Is there any way?

This one is the best method to find out the R.drawable.img1 value when u click on the ImageView in your program. The method is something like that in main program. First of all save the image value in the tag like that

public...activity 
{
    //-----this resource name is retrieved through the tag value of the drawable of (touched) ImageView //image ontouchlistener event...
    ImageView imgview1.setTag("img1"); //as of R.drawable.img1
    ImageView imgview2.setTag("img2"); //as of R.drawable.img2

    onTouchListnener event... on imageView
    {    
        Object tag = imageView.getTag();                    
        int id = getResources().getIdentifier( tag, "drawable", this.getPackageName() );
        switch(id)
        {
            case R.drawable.img1:
                //do someoperation of ur choice
                break;
            case R.drawable.img2:
                //do someoperation of ur choice
                break:
        }//end of switch

    }//end of touch listener event

}//end of main activity
