Hola chicos, ¿cómo podría ordenar una vista de reciclador por los datos que están dentro de una vista de texto determinada que está dentro de cada elemento dentro de la vista de reciclaje. También me gustaría saber cómo agregar un encabezado a cada elemento que sea diferente en los datos. es decir.

Estoy ordenando tratando de ordenar por fecha y quiero que todas las fechas de xyz se agrupen bajo un encabezado y las fechas de 123 se agrupen bajo otro generador. ¿Es esto posible gracias.

Publicaré mi adaptador por ahora si necesita otra información, solo comente debajo de esto. Salud.

Aquí está el código que se indica en el fragmento en el que se encuentra la vista del reciclador.

 mAdapter = new RecyclerViewAdapterTransactions(getActivity(), account, amount, incomeExpense, type, date, category, uid, description);
             ((RecyclerViewAdapterTransactions) mAdapter).setMode(Attributes.Mode.Single);
             recyclerView.setHasFixedSize(true);
             recyclerView.setAdapter(mAdapter);

Adaptador RecyclerViewAdapterTransactions:

    public class RecyclerViewAdapterTransactions extends RecyclerSwipeAdapter<RecyclerViewAdapterTransactions.SimpleViewHolder>{

   public static class SimpleViewHolder extends RecyclerView.ViewHolder {

      SwipeLayout swipeLayout;
      ImageButton buttonDelete;
      ImageButton buttonEdit;

      TextView textViewAccount;
      TextView textViewAmount;
      TextView textViewIncomeExpense;
      TextView textViewDate;
      TextView textViewUID;
      TextView textViewCategory;
      TextView textViewDescription;
      TextView textViewType;

      public SimpleViewHolder(View itemView) {
         super(itemView);
         swipeLayout = (SwipeLayout) itemView.findViewById(R.id.swipeLayoutTransactions);
         buttonDelete = (ImageButton) itemView.findViewById(R.id.imageButtonTransactionDelete);
         buttonEdit = (ImageButton) itemView.findViewById(R.id.imageButtonTransactionEdit);

         textViewAmount = (TextView) itemView.findViewById(R.id.textViewAmount);
         textViewAccount = (TextView) itemView.findViewById(R.id.textViewAccount);
         textViewIncomeExpense = (TextView) itemView.findViewById(R.id.textViewIncomeExpense);
         textViewType = (TextView) itemView.findViewById(textViewTransactionType);
         textViewDate = (TextView) itemView.findViewById(R.id.textViewDateOfTransaction);
         textViewCategory = (TextView) itemView.findViewById(R.id.textViewCategory);
         textViewUID = (TextView) itemView.findViewById(R.id.id);
         textViewDescription = (TextView) itemView.findViewById(R.id.textViewDescription);


      }
   }
