Nein so meine ich das nicht. Ich möchte jeweils die letzten Einträge der 3 Listen in einem entry_item_layout bzw einem Reylcerview Item ausgeben. Die nächsten Einträge der 3 Listen in folgende Recyclerviews bzw in einem neuen entry_item_layout. Bin nicht sicher ob das verständlich ist aber hier ein Screenshot um das zu verdeutlichen:

Die Werte von "liezen_lagerhaus_tankstelle" sollen in das Layout "layoutLagerhaus", die Werte von "liezen_jet_tankstelle" in das Layout "layoutJet" und die Werte von "trautenfels_shell_tankstelle" in das Layout "layoutShell" der entry_item_layout.xml.

Da wo noch "preis" steht sollen die entsprechenden Werte eingefügt werden also noch "liezen_jet_tankstelle" und "trautenfels_shell_tankstelle".

Sorry, hab erst jetzt bemerkt das wer auf meinen Post geantwortet hat.

Ich möchte jeweils den letzten Eintrag der 3 Listen im entry_item_layout ausgeben.

Hier ist das XML davon:

Hallo,

ich möchte gerne in einem Recyclerview Item den letzten Eintrag von jeweils 3 Array Listen ausgeben. In den folgenden Items natürlich die nächsten Einträge der 3 Listen usw.. Leider verstehe ich nicht wieso nicht alle Daten vom letzten Eintrag in einem Recyclerview Item ausgegeben werden sondern die Einträge verteilt werden auf die nächsten Recyclerviews. Wo könnte das Problem liegen?

Code

public class EntryAdapter extends RecyclerView.Adapter<EntryAdapter.EntryViewHolder> {

    private List<Entry_Pagination> lagerhausEntries;
    private List<Entry_Pagination> jetEntries;
    private List<Entry_Pagination> shellEntries;

    public EntryAdapter(List<Entry_Pagination> lagerhausEntries, List<Entry_Pagination> jetEntries, List<Entry_Pagination> shellEntries) {
        this.lagerhausEntries = lagerhausEntries;
        this.jetEntries = jetEntries;
        this.shellEntries = shellEntries;
    }

    @NonNull
    @Override
    public EntryViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.entry_item_layout, parent, false);
        return new EntryViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(@NonNull EntryViewHolder holder, int position) {
        // Determine which tankstelle (gas station) the entry belongs to
        Entry_Pagination entry;
        int itemViewType = getItemViewType(position);
        if (itemViewType == 0) {
            entry = lagerhausEntries.get(position);
            holder.bindEntry("liezen_lagerhaus_tankstelle", entry);
        } else if (itemViewType == 1) {
            entry = jetEntries.get(position - lagerhausEntries.size());
            holder.bindEntry("liezen_jet_tankstelle", entry);
        } else {
            entry = shellEntries.get(position - lagerhausEntries.size() - jetEntries.size());
            holder.bindEntry("trautenfels_shell_tankstelle", entry);
        }
    }


    @Override
    public int getItemViewType(int position) {
        if (position < lagerhausEntries.size()) {
            return 0; // Lagerhaus Tankstelle
        } else if (position < lagerhausEntries.size() + jetEntries.size()) {
            return 1; // Jet Tankstelle
        } else {
            return 2; // Shell Tankstelle
        }
    }

    @Override
    public int getItemCount() {
        // Total count is the sum of entries from all tankstellen
        return lagerhausEntries.size() + jetEntries.size() + shellEntries.size();
    }
