IllegalArgumentException: width should be > 0?

Question

I use Asynctask to set the image to RecyclerView when the page is executed

Asynctask takes a recyclerView's width and height

However, this error occurs 'IllegalArgumentException: width should be > 0'

I looked up similar cases and saw that it was a problem to run too soon

So I tried onPause, onStart, and onPostCreated, but the same result came up

Put it in the button and run it to get the result I want

Therefore, I think that the point of execution is the problem

When should I call this method to get the page to run and immediately set the

image to recyclerView?

Can you post what have you tried i.e the piece of code and the error log ? — Chithra B, Feb 05 '18 at 10:51

Without any code from your end, what I can suggest is to do something like :

recyclerView.post(new Runnable() {
                @Override
                public void run() {
                     // Execute your AsyncTask here by providing Width
                }
            });

Because the problem I can guess is your RecyclerView is not properly inflated when you call the AsyncTask with width

Also I would suggest you to put the method after you call setAdapter

I will have to enter code and error next time. Thank you for your advice. Have a nice day! — Jshin, Feb 05 '18 at 11:30
