Android set Tag, findViewWithTag -

I'm trying to find an image view by tag. I assign a tag to ImageView, but when I try to find ViewWithTag, it gives this blank space. I have read that I should add the child to the adapter, but the view does not have this function. Can anyone tell me how can I do this?

  Imejiwu principal = (Imejwu) searching for Vivibiaiaidi (RID. In principal.setTag ( "Prime");   
 Other Class (async task) I I have references  
  View noMiembros = new scene (reference); ImageView er = (ImageView) noMiembros.findViewWithTag ( "principal"); er.setImageBitmap (result); an activity AsyncTask pass and just use:  
    
 
 Imejiwu principal = ( Imageview) passed. Activate Kfindwubiaiaidi (Arkaidikimian_homeji);   
 or go Inflater context like this:  
  Leautinfletr inflater = layout Inflaterkfrom (reference); align = inflater.inflate (R.layout.your_viw_that_contains_that_image, parents, check false); ImageView principal = (ImageView) row.findViewById (R.id.imagen_home_0); // or tags principal = (ImageView) row.findViewWithTag ( "principal ");   
 Good luck.
