Why there is no method to get Resource Name from Drawable object

To create Drawable object from any resource we can use the following code (my image name is arrow_selected.png)

Drawable d =getResources().getDrawable(R.drawable.arow_selected);

But later in the application I want to get the resource name from this drawable object. I didnot find any method to get resource name like the following

d.getResourceName();

Why there is no such method in android API. How can I get Resource Name from Drawable object?

In case if you really need that functionality (I'm not sure you do), you could create your own class that extends Drawable class and receives Resource ID in a parameter of the constructor.

Then you need to store this ResID in a special field in your class and implement getter and setter for that field. Voila!

I was doing a search for this as well but I came up with the following solution:

String name = context.getResources().getResourceEntryName(imageResID);

I hope this helps.

Because a Drawable does not have to be created from a resource.

How can I get Resource Name from Drawable object?

You don't. You track it elsewhere (e.g., other data members of a class).
