改造，多個模型一個適配器

這是我的JSON：改造，多個模型一個適配器

     "deg": 264, 
     "clouds": 88, 
     "rain": 4.72 
    } 
    ] 
}

因爲有些數據我想在這裏找回嵌套我已經取得了多個模型。

public class Response { 

    @SerializedName("city") 
    @Expose 
    private City city; 
    @SerializedName("cod") 
    @Expose 
    private String cod; 
    @SerializedName("message") 
    @Expose 
    private Double message; 
    @SerializedName("cnt") 
    @Expose 
    private Integer cnt; 
    @SerializedName("list") 
    @Expose 
    private List<WeatherList> list = new ArrayList<WeatherList>(); 


public class WeatherList { 

    @SerializedName("dt") 
    @Expose 
    private Integer dt; 
    @SerializedName("temp") 
    @Expose 
    private Temp temp; 
    @SerializedName("pressure") 
    @Expose 
    private Double pressure; 
    @SerializedName("humidity") 
    @Expose 
    private Integer humidity; 
    @SerializedName("weather") 
    @Expose 
    private List<Weather> weather = new ArrayList<Weather>(); 
    @SerializedName("speed") 
    @Expose 
    private Double speed; 
    @SerializedName("deg") 
    @Expose 
    private Integer deg; 
    @SerializedName("clouds") 
    @Expose 
    private Integer clouds; 
    @SerializedName("rain") 
    @Expose 
    private Double rain;

等等我覺得在這裏粘貼所有的模型沒有意義。當然，他們都包含setters和getters。

我不知道（我在網上找不到任何相關主題）如何將數據從多個模型一次傳遞給適配器。

public class ForecastAdapter extends RecyclerView.Adapter<ForecastAdapter.ForecastViewHolder> { 
    private List<Response> forecasts; 
    private int rowLayout; 
    private Context context; 

    constructor, getters and setters 

    @Override 
    public ForecastAdapter.ForecastViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View view = LayoutInflater.from(parent.getContext()).inflate(rowLayout, parent, false); 
     return new ForecastViewHolder(view); 
    } 

    @Override 
    public void onBindViewHolder(ForecastViewHolder holder, final int position) { 
     ?????? 
    } 

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


    public static class ForecastViewHolder extends RecyclerView.ViewHolder { 
     LinearLayout forecastLayout; 
     TextView date; 
     TextView tempDay; 
     TextView tempNight; 
     TextView tempMin; 
     TextView tempMax; 

     public ForecastViewHolder(View view) { 
      super(view); 
      forecastLayout = (LinearLayout) view.findViewById(R.id.forecast_item_layout); 
      date = (TextView) view.findViewById(R.id.date); 
      tempDay = (TextView) view.findViewById(R.id.temp_day); 
      tempNight = (TextView) view.findViewById(R.id.temp_night); 
      tempMin = (TextView) view.findViewById(R.id.temp_min); 
      tempMax = (TextView) view.findViewById(R.id.temp_max); 
     } 
    } 

}

我想從所有型號的傳遞數據，並將其設置在onBindViewHolder方法，但我不知道怎麼辦。有任何想法嗎？

在您的適配器中創建一個構造函數。創建適配器時，你得到的迴應

public ForecastAdapter(Context context,List<Response> forecasts) { 
    this.forecasts = forecasts; 
    this.context=context; 
}

併爲每TextView的在onbindViewHolder

@Override 
public void onBindViewHolder(ForecastViewHolder holder, final int position) { 
    holder.date.setText(forecasts.get(position).getDate()); 
}

組數據這樣。

變化領域

private List<Response> forecasts;到private Response response;

在getItemCount()變化

return forecasts.size();返回return response.getList().size();

重命名類WeatherList更直觀DayForecast

最後

@Override 
public void onBindViewHolder(ForecastViewHolder holder, final int position) { 
    DayForecast dayForecast = response.getList().get(position); 
    holder.date.setText(convertToString(dayForecast.getDt())); 
    holder.tempDay.setText(dayForecast.getTemp().toString)); 
    //and so on.. 
}
