How to execute the method with returned value from an asynctask?

Question

A method is for Custom View, and Asnyctask B is for getting URL. To load an image on Custom View with returned URL from Asynctask, I need to execute Custom View method after the asynctask. When I call the method after asynctask, the method gets null because asynctask didnt return the value yet. How can I handle this problem?

customView= findViewById(R.id.custom_view);
UrlRequest urlRequest = new UrlRequest(this).build(); // AsyncTask
customView.loadImg(urlRequest); // null value

On Logcat, customView.loadImg method run first, then urlRequest is returned.

I expect the returned data, but the actual output is null...

it's gonna be my last option, but I need to separate those two... haha thanks tho — AwesomeCho, Jul 31 '19 at 08:18
Use Glide or Picasso it is far better than writing custom method. You can use an interface with an async method to get the response — OhhhThatVarun, Jul 31 '19 at 08:25
you can start image loading in `onPostExecute()` of Asnyctask B — Shrey Garg, Jul 31 '19 at 08:28

Maybe check this out. It should work the same way as await does in c#. I am not completely sure tho
