我在androidstudio中使用改型从mysql检索数据。我想在recyclerview中显示数据。数据是 id_departure = K1 (字符串), id_destination = K2 (字符串), schedule = 2020-11-23 12:00:00 (日期时间)。我可以在android studio中以不同的值显示数据吗?例如: K1 代表伦敦, K2 代表伯明翰, K3 代表曼彻斯特, date =2020年11月23日, time = 12:00. 有人知道怎么做吗?谢谢您。以下是我在myorderactivity中的代码:

public class MyOrderActivity extends AppCompatActivity {
private RecyclerView rvHistory;
private RecyclerView.Adapter historyAdapter;
private RecyclerView.LayoutManager lmHistory;
private List<HistoryData> listData = new ArrayList<>();
private SwipeRefreshLayout swipeRefreshLayout;
private ProgressBar progressBar;
SessionManager sessionManager;
String idUser;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my_order);

    rvHistory = findViewById(R.id.rv_history);
    lmHistory = new LinearLayoutManager(MyOrderActivity.this, LinearLayoutManager.VERTICAL, false);
    rvHistory.setLayoutManager(lmHistory);
    swipeRefreshLayout = findViewById(R.id.swipe_refresh);
    progressBar = findViewById(R.id.progress_bar);

    sessionManager = new SessionManager(MyOrderActivity.this);
    idUser = sessionManager.getUserDetail().get(SessionManager.ID_USERS);

    showRecyclerList(idUser);

    swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            swipeRefreshLayout.setRefreshing(true);
            showRecyclerList(idUser);
            swipeRefreshLayout.setRefreshing(false);
        }
    });
}

private void showRecyclerList(String idUser) {
    progressBar.setVisibility(View.VISIBLE);

    ApiInterface apiInterface = ApiClient.getClient().create(ApiInterface.class);
    Call<History> historyCall = apiInterface.historyResponse(idUser);
    historyCall.enqueue(new Callback<History>() {
        @Override
        public void onResponse(Call<History> call, Response<History> response) {
            if(response.body() != null && response.isSuccessful() && response.body().isStatus()) {
                String message = response.body().getMessage();
                Toast.makeText(MyOrderActivity.this, message, Toast.LENGTH_SHORT).show();

                listData = response.body().getData();
                historyAdapter = new HistoryAdapter(MyOrderActivity.this, listData);
                rvHistory.setAdapter(historyAdapter);
                historyAdapter.notifyDataSetChanged();
                progressBar.setVisibility(View.INVISIBLE);
            }
        }

        @Override
        public void onFailure(Call<History> call, Throwable t) {
            progressBar.setVisibility(View.INVISIBLE);
            Toast.makeText(MyOrderActivity.this, t.getLocalizedMessage(), Toast.LENGTH_SHORT).show();

        }
    });

}
}

public HistoryAdapter(Context ctx, List<HistoryData> listHistory) {
    this.ctx = ctx;

    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_cardview_history, parent, false);
    HistoryHolder holder = new HistoryHolder(view);
    return holder;
}

@Override

    HistoryData historyData = listHistory.get(position);

    holder.tvDeparture.setText(historyData.getIdDeparture());
    holder.tvDestination.setText(historyData.getIdDestination());
    holder.tvDate.setText(historyData.getSchedule());
    holder.tvTime.setText(historyData.getSchedule());

}

@Override

    return listHistory.size();

public class HistoryHolder extends RecyclerView.ViewHolder {
    TextView tvDeparture, tvDestination, tvDate, tvTime;

    public HistoryHolder(@NonNull View itemView) {
        super(itemView);

        tvDeparture = itemView.findViewById(R.id.tv_item_departure);
        tvDestination = itemView.findViewById(R.id.tv_item_destination);
        tvDate = itemView.findViewById(R.id.tv_item_date);
        tvTime = itemView.findViewById(R.id.tv_item_time);
    }
}
