Hi Friends i had struck in this problem from 2 days i dont know whats the problem here i am using the Fast Adapter by mikepenz where i have two recycler view in this.Here i am getting this error
java.lang.RuntimeException: You have to provide a ViewHolder with a constructor which takes a view!
at com.mikepenz.fastadapter.items.AbstractItem$ReflectionBasedViewHolderFactory.create(AbstractItem.java:349)
I think i had set the everything correct as i am using same format in other class as well but i am only facing this issue class only and i dont have activated the progurard please find the below code

As far as I can tell you are using an outdated version of the FastAdapter which still had a feature enabled, to automatically detect the provided ViewHolder. As this functionality sometimes lead to the above error message (if used with proguard) it was removed in a newer version and replaced by a simple getViewHolder method.
@Override
public ViewHolder getViewHolder(View v) {
return new ViewHolder(v);
}
This new approach was introduced with the FastAdapter v2.5.0: https://github.com/mikepenz/FastAdapter/blob/develop/MIGRATION.md#v250
For older versions of the FastAdapter, there was the concept of a ViewHolderFactory which would (as an alternative to the automatic detection, which is not working in your case) provide the ViewHolder to the FastAdapter
Basically you'd implement the ViewHolderFactory and define the ViewHolderFactory in your item.
private static final ViewHolderFactory<? extends ViewHolder> FACTORY = new ItemFactory();
In addition you'd need the following:
/**
* our ItemFactory implementation which creates the ViewHolder for our adapter.
* It is highly recommended to implement a ViewHolderFactory as it is 0-1ms faster for ViewHolder creation,
* and it is also many many times more efficient if you define custom listeners on views within your item.
*/
protected static class ItemFactory implements ViewHolderFactory<ViewHolder> {
public ViewHolder create(View v) {
return new ViewHolder(v);
}
}
/**
* return our ViewHolderFactory implementation here
*
* @return
*/
@Override
public ViewHolderFactory<? extends ViewHolder> getFactory() {
return FACTORY;
}
You can see the whole thing here: https://github.com/mikepenz/FastAdapter/blob/v2.2.0/app/src/main/java/com/mikepenz/fastadapter/app/items/IconItem.java#L24
As an alternative adjusting the proguard rules could also work.
My recommendation is to update to one of the latest FastAdapter releases, as this was greatly simplified and enhanced.
