How to get the image name of the ImageView in Android? -

-

i have imageview in android . want name of image set in in imageview. how can ? 

imageview v = (imageview)findviewbyid(r.id.img); //string name = findimagename(v); if( name.equals(a)) {    //do }  else{    //do }

for first of need set tag imageview

<imageview     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:id="@+id/imageview1"      android:background="@drawable/bg1"     android:tag="bg1"/>

now image name set on imageview doing following,

imageview v = (imageview)findviewbyid(r.id.img); string backgroundimagename = string.valueof(v.gettag());

and should return image tag name "bg1".

now compare tag names or use further process

if( backgroundimagename.equals(bg1)) {    //do }  else{    //do }

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
