java - 如何创建数组列表，其中一个参数将等于另一个数组的参数

Question

我有关于天气的 API 调用。在响应中，我得到了 WeatherResponse，其中包含每日温度、每小时温度和每分钟温度的数组列表。在另一边，我有 RecyclerView，它从每日数组中显示一整天。当我单击 RecyclerView 上的某一天时，我需要展开单击的项目并显示同一天的所有时间。我创建了包含 TextView(Day from daily) 和 RecyclerView(Hours) 的 View ，其中将包含单击当天的小时数。在我的 Days rv 适配器中，我制作了监听当天点击的界面并在主要 Activity 中实现它。点击日和每日数组列表的界面调用位置。我在每日 rv 内为每小时 rv 创建了另一个适配器。那么，如何创建所选日期的时间列表？

这是 WeatherResponse

public class WeatherResponse extends BaseObservable implements Parcelable {

    @SerializedName("minutely")
    @Expose
    private List<Minutely> minutely = null;
    @SerializedName("hourly")
    @Expose
    private List<Hourly> hourly = null;
    @SerializedName("daily")
    @Expose
    private List<Daily> daily = null;

    public WeatherResponse() {
    }

    @Bindable
    public List<Minutely> getMinutely() {
        return minutely;
    }

    public void setMinutely(List<Minutely> minutely) {
        this.minutely = minutely;
    }

    @Bindable
    public List<Hourly> getHourly() {
        return hourly;
    }

    public void setHourly(List<Hourly> hourly) {
        notifyPropertyChanged(BR.hourly);
        this.hourly = hourly;
    }

    @Bindable
    public List<Daily> getDaily() {
        return daily;
    }

    public void setDaily(List<Daily> daily) {
        notifyPropertyChanged(BR.daily);
        this.daily = daily;
    }

}

和每小时模型

public class Hourly implements Parcelable
{

    @SerializedName("dt")
    @Expose
    private int dt;
    @SerializedName("temp")
    @Expose
    private double temp;
    @SerializedName("feels_like")
    @Expose
    private double feelsLike;
    @SerializedName("pressure")
    @Expose
    private int pressure;
    @SerializedName("humidity")
    @Expose
    private int humidity;
    @SerializedName("dew_point")
    @Expose
    private double dewPoint;
    @SerializedName("clouds")
    @Expose
    private int clouds;
    @SerializedName("wind_speed")
    @Expose
    private double windSpeed;
    @SerializedName("wind_deg")
    @Expose
    private int windDeg;
    @SerializedName("weather")
    @Expose
    private List<Weather> weather = null;
    @SerializedName("rain")
    @Expose
    private Rain rain;
}

和每日模型

public class Daily extends BaseObservable implements Parcelable {

    @SerializedName("dt")
    @Expose
    private int dt;
    @SerializedName("sunrise")
    @Expose
    private int sunrise;
    @SerializedName("sunset")
    @Expose
    private int sunset;
    @SerializedName("temp")
    @Expose
    private Temp temp;
    @SerializedName("feels_like")
    @Expose
    private FeelsLike feelsLike;
    @SerializedName("pressure")
    @Expose
    private int pressure;
    @SerializedName("humidity")
    @Expose
    private int humidity;
    @SerializedName("dew_point")
    @Expose
    private double dewPoint;
    @SerializedName("wind_speed")
    @Expose
    private double windSpeed;
    @SerializedName("wind_deg")
    @Expose
    private int windDeg;
    @SerializedName("weather")
    @Expose
    private List<Weather> weather = null;
    @SerializedName("clouds")
    @Expose
    private int clouds;
    @SerializedName("rain")
    @Expose
    private double rain;
    @SerializedName("uvi")
    @Expose
    private double uvi;
}

日常适配器绑定(bind)功能:

@Override
    public void onBindViewHolder(@NonNull DayViewHolder holder, int position) {
        Daily daily = dailies.get(position);
        holder.dayItemViewBinding.setDaily(daily);
        holder.dayItemViewBinding.getRoot().setTag(position);

        holder.dayItemViewBinding.getRoot().setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int position = (int) v.getTag();
                if (callback != null){
                    callback.onDayItemClick(position, daily);
                }
            }
        });

Answer 1

我明白了。

private void fillHoursRecyclerView(Daily daily) {
        selectedDay = new TimeUtils();
        hourToShow = new TimeUtils();
        selectedDay.getReadableDay(daily.getDt());
        ArrayList hourlies = new ArrayList<>();

        for (int i = 0; i < weatherResponseViewModel.getHourlyWeatherData().getValue().size(); i++) {
            if (hourToShow.getReadableDay(weatherResponseViewModel.getHourlyWeatherData().getValue().get(i).getDt()).equals(selectedDay.getReadableDay(daily.getDt()))) {
                hourlies.add(weatherResponseViewModel.getHourlyWeatherData().getValue().get(i));
            }
        }

        hoursRvAdapter = new HoursRvAdapter(getApplicationContext(), hourlies);
        hoursRecyclerView = findViewById(R.id.hoursRecyclerView);
        hoursRecyclerView.setLayoutManager(new LinearLayoutManager(this));
        hoursRecyclerView.setItemAnimator(new DefaultItemAnimator());
        hoursRecyclerView.setAdapter(hoursRvAdapter);
        hoursRecyclerView.setVisibility(View.VISIBLE);
        hoursRvAdapter.notifyDataSetChanged();
    }

public class TimeUtils {

    private String readableDay;

    public String getReadableDay(int dt) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            readableDay = Instant.ofEpochSecond(dt)
                    .atZone(ZoneId.of("Asia/Jerusalem"))
                    .getDayOfWeek()
                    .getDisplayName(TextStyle.FULL, Locale.US);
        }
        return readableDay;
    }

}
