How to check which current image resource is attached to ImageView in android xml?

Question

I want to check which image resource is attached to ImageView in xml, I am able to check that which image resource is attached to image view but my requirement is to how to check that the ImageView has the same resource which I have set into xml or not, based on that I need to perform some actions.Code always executes else part. Following is my code,

  if (regProfile.getDrawable() == getResources().getDrawable( R.drawable.ivpic))      {       Toast.makeText(_con, "Image is ivPic", Toast.LENGTH_LONG).show();        // new RegisterAsyntaskNew().execute();      }    else      {      Toast.makeText(_con, "Image isn't ivPic", Toast.LENGTH_LONG).show();       // new RegisterAsyntask().execute();      }

Hi please have a try with this as follows

if (regProfile.getDrawable().getConstantState() == getResources().getDrawable( R.drawable.ivpic).getConstantState())  {   Toast.makeText(_con, "Image is ivPic", Toast.LENGTH_LONG).show();    // new RegisterAsyntaskNew().execute();  }  else  {  Toast.makeText(_con, "Image isn't ivPic", Toast.LENGTH_LONG).show();   // new RegisterAsyntask().execute();  } 

please use .getConstantState() to compare

EDIT:

.getResources().getDrawable(imageResource) 

Is deprecated in API21, so I changed Jitesh Upadhyay's answer.

Here is the code:

@SuppressWarnings("deprecation") @SuppressLint("NewApi") public static boolean checkImageResource(Context ctx, ImageView imageView,         int imageResource) {     boolean result = false;      if (ctx != null && imageView != null && imageView.getDrawable() != null) {         ConstantState constantState;          if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {             constantState = ctx.getResources()                     .getDrawable(imageResource, ctx.getTheme())                     .getConstantState();         } else {             constantState = ctx.getResources().getDrawable(imageResource)                     .getConstantState();         }          if (imageView.getDrawable().getConstantState() == constantState) {             result = true;         }     }      return result; }
