Question

在我的应用程序的某些部分，我在自定义对话框上有RecyclerView，但在我设置数据时，请保留在Recyclerview中并且不要刷新新数据，例如下面的代码是我的show custom Dialog：< / p>

transferred_to_user_history.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        List<Transactions> transactionsHistoryList = Collections.emptyList();
        transactionsHistoryList = realm.where(Transactions.class)
                .equalTo("toUser", username)
                .equalTo("destinationEwalletId", latestChosenUserEwallet)
                .findAll();
        Log.e("transactionsHistoryList", transactionsHistoryList.size() + "");
        if (getChosenTransferredHistory == null)
            getChosenTransferredHistory =
                    new GetChosenEwalletTransferredHistory(ActivityTransferMoney.this)
                    .setData(transactionsHistoryList);

        getChosenTransferredHistory.setOnTransactiontHistory(new GetChosenEwalletTransferredHistory.IOnChooseTransactionHistory() {
            @Override
            public void getItem(EwalletsHistory item) {
                getChosenTransferredHistory.dismissDialog();
                getChosenTransferredHistory = null;
            }
        });
        getChosenTransferredHistory.showDialog();
    }
});

如果第一次附加transactionsHistoryList.size()变量1并且在RecyclerView上显示数据，并且在dismissDialog之后显示数据并重新附加空结果，我在最后一个showDialog附加了数据，

首先showDialog：

transactionsHistoryList.size(): 1

第二个showDialog：

transactionsHistoryList.size(): 0

在第二部分我有关于recylerview的一些数据，但transactionsHistoryList.size()是0

我的自定义对话框：

public GetChosenEwalletTransferredHistory(ActivityTransferMoney context) {
    this.context = context;
    realm = realm.getDefaultInstance();

    dialog = new Dialog(context, R.style.theme_dialog);
    dialog.setContentView(R.layout.dialog_user_transferred_history);

    transferred_history = (RecyclerView) dialog.findViewById(R.id.transferred_history);

    List<Transactions> r = new ArrayList<>();

    transferred_history.setLayoutManager(new LinearLayoutManager(context));
    adapter = new GetLatestUserTransferredHistoryAdapter(context, r);
    transferred_history.setAdapter(adapter);
}

public GetChosenEwalletTransferredHistory setData(List<Transactions> result) {
    adapter.setData(result);
    adapter.notifyDataSetChanged();
    return this;
}

我的适配器：

public class GetLatestUserTransferredHistoryAdapter extends RecyclerView.Adapter<GetLatestUserTransferredHistoryAdapter.EwalletHistoryViewHolder> {

    public static IOnItemClickListener iOnItemClickListener;
    List<Transactions> list = Collections.emptyList();
    Context context;

    public GetLatestUserTransferredHistoryAdapter(Context context, List<Transactions> list) {
        this.list = list;
        this.context = context;
    }

    @Override
    public EwalletHistoryViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View                     v      = LayoutInflater.from(parent.getContext()).inflate(R.layout.latest_transactions_items, parent, false);
        EwalletHistoryViewHolder holder = new EwalletHistoryViewHolder(v);
        return holder;
    }

    @Override
    public void onBindViewHolder(EwalletHistoryViewHolder holder, final int position) {
        holder.transaction_report_row.setText(list.get(position).getMoney() + list.get(0).getCurrencySymbol() + " on: " + list.get(position).getCreatedAt());
    }

    @Override
    public int getItemCount() {
        return list.size();
    }

    @Override
    public void onAttachedToRecyclerView(RecyclerView recyclerView) {
        super.onAttachedToRecyclerView(recyclerView);
    }

    public void setData(List<Transactions> list) {
        this.list = list;
    }
}

Answer 1

public void setData(List<Transactions> list) {
    this.list = list;
}

更改为：

public void setData(List<Transactions> list) {
    this.list.clear();
    this.list.addAll(list);
}

列表未使用=
