For some reason, I wrote every line you wrote but it does not work at all. The whole thing is blank when I run, there are visible black lines separating each item yes, but nowhere do the items and their corresponding sub-items to be seen. No words whatsoever, btw I did not add any image , just a simple title and des thats it
I did everything as in the video, but go to the activity application crashes java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ImageView.setImageResource(int)' on a null object reference
