Recycler view not working
Update
View is loaded now, after i implemented this :-
holder.time.setText(user.getTime());
to
holder.time.setText(Integer.toString(user.getTime()));
but I still get this message in Log :-
E/RecyclerView: No adapter attached; skipping layout
any idea about this ?
I have used volley to get data from server and then show the data on Recycler view using Cardview. But it is crashing the app with error saying that adapter not attached. Although I have attached the adapter. I am not able to find the issue. Please Help.

try changing code
holder.time.setText(user.getTime());
to
holder.time.setText(Integer.toString(user.getTime()));

Amod GokhaleThe problem is in this code
holder.time.setText(user.getTime());
As textview have overloaded setText(int)
Method which supposed to be used with string resources, these resources will be resolved by integer number defined like R.string.* .
In your case user.getTime() returning integer value that will be treated like a predefined XML string resource(that will not exist in your case).

AlokE/RecyclerView: No adapter attached; skipping layout
That means there is no adapter, therefore the layout will be skipped, that is not the error is info. If you don't want to see it anymore, then attach an empty adapter and then update the adapter.
This is your error:
E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.ravibhardwaj.kbcmaster, PID: 6718
android.content.res.Resources$NotFoundException: String resource ID #0xf0
Because of this:
holder.time.setText(user.getTime());
Because:
public Integer getTime() {
return time;
}
That is an integer, setText() can accept String or int, because of resources such as R.string.something is an int. Fix it:
holder.time.setText(String.valueOf(user.getTime()));
