RecyclerView 2 lists in one

I am trying to create something similar to this:

RecyclerView

Instead of folders and files I want to have incomplete items and completed items.

I am new to RecyclerViews, how would I manage to get two unrelated lists such as folders and files into one RecyclerView that scrolls as one?

You could use heterogenous RecyclerView which supports more than one viewType or view holders. Your dataSet could be List<Object> or a marker class which supports the models Files and Folders for example and then you could do something like this in your adapter :

public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
class ViewHolderFolders extends RecyclerView.ViewHolder {
    ...
    public ViewHolderFolders(View itemView){
    ...
    }
}

class ViewHolderFiles extends RecyclerView.ViewHolder {
    ...
    public ViewHolderFiles(View itemView){
    ...
}

@Override
public int getItemViewType(int position) {
    //Let us say you return 0 for folders and 1 for files
    //This is just an example you could write your own logic but make sure to  differenciate the two
    //Folders and Files in here are model class used to populate the 
    //recyclerview with. This is just an example.
    if (yourDataSet.get(position) instanceof Folders) {
        return 0;
    } else{
        return 1;
    }

}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
     switch (viewType) {
         case 0: return new ViewHolderFolders(...);
         case 1: return new ViewHolderFiles(...);
         //Your code here
     }
}

@Override
public void onBindViewHolder(final RecyclerView.ViewHolder holder, final int position) {
    switch (holder.getItemViewType()) {
        case 0:
            ViewHolderFolders viewHolderFolders = (ViewHolderFolders)holder;
            ...
            break;

        case 1:
            ViewHolderFiles viewHolderFiles = (ViewHolderFiles)holder;
            ...
            break;
    }
}

}

You can use a sectioned recyclerView for this. Where you can have section as header and each header with its own items.

Refer to this library: Sectioned RecyclerView
