天气预报、生活指数的数据请求与渲染

6. 天气预报

天气预报是预测未来几天的天气，常用列表显示，实现这个功能的业务逻辑是：访问API、获取返回值、列表配置、数据渲染。首先是API接口。

① 新增API接口

根据和风天气中的文档，得知未来3-7天的天气预报接口为：

https://free-api.heweather.net/s6/weather/forecast?key=3086e91d66c04ce588a7f538f917c7f4&location=福田区

在网页上访问得到返回值，生成一个实体

代码如下：

package com.llw.goodweather.bean;

import java.util.List;

public class WeatherForecastResponse {

    private List<HeWeather6Bean> HeWeather6;

    public List<HeWeather6Bean> getHeWeather6() {
        return HeWeather6;
    }

    public void setHeWeather6(List<HeWeather6Bean> HeWeather6) {
        this.HeWeather6 = HeWeather6;
    }

    public static class HeWeather6Bean {
        /**

            }
        }
    }
}

接下来在ApiService中添加

代码如下：

	/**
     * 未来3 - 7天天气预报
     */
    @GET("/s6/weather/forecast?key=3086e91d66c04ce588a7f538f917c7f4")
    Call<WeatherForecastResponse> getWeatherForecast(@Query("location") String location);

② 修改订阅器

接下来修改订阅器WeatherContract

WeatherContract代码如下：

package com.llw.goodweather.contract;

        public void todayWeather(final Context context, String location) {
            //得到构建之后的网络请求服务，这里的地址已经拼接完成，只差一个location了
            ApiService service = ServiceGenerator.createService(ApiService.class);
            //设置请求回调  NetCallBack是重写请求回调
            service.getTodayWeather(location).enqueue(new NetCallBack<TodayResponse>() {
                //成功回调
                @Override
                public void onSuccess(Call<TodayResponse> call, Response<TodayResponse> response) {

                        getView().getTodayWeatherResult(response);
                    }
                }

                //失败回调
                @Override
                public void onFailed() {
                    if (getView() != null) {//当视图不会空时获取错误信息
                        getView().getDataFailed();

        }


        /**

        public void weatherForecast(final Context context,String location){
            ApiService service = ServiceGenerator.createService(ApiService.class);
            service.getWeatherForecast(location).enqueue(new NetCallBack<WeatherForecastResponse>() {
                @Override
                public void onSuccess(Call<WeatherForecastResponse> call, Response<WeatherForecastResponse> response) {

                    }
                }
            });
        }
    }


    public interface IWeatherView extends BaseView {
        //查询当天天气的数据返回
        void getTodayWeatherResult(Response<TodayResponse> response);
        //查询天气预报的数据返回
        void getWeatherForecastResult(Response<WeatherForecastResponse> response);
        //错误返回
        void getDataFailed();
    }
}

接下来修改布局，增加列表和适配器

③ 修改布局，增加列表和适配器

代码中

这个时候你的MainActivity.java会报错

这是因为订阅器里面的内容没有写入。鼠标点击，Alt + Enter

接下来创建列表的item 在layout目录下创建item_weather_forecast_list.xml文件

代码如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <LinearLayout
        android:padding="@dimen/sp_12"
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <!--日期-->
        <TextView
            android:id="@+id/tv_date"
            android:text="1234"
            android:textSize="@dimen/sp_14"
            android:textColor="#FFF"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"/>
        <!--天气描述-->
        <TextView
            android:gravity="center"
            android:id="@+id/tv_info"
            android:textSize="@dimen/sp_14"
            android:textColor="#FFF"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"/>

        <!--最低温、最高温-->
        <TextView
            android:gravity="right"
            android:id="@+id/tv_low_and_height"
            android:textSize="@dimen/sp_14"
            android:textColor="#FFF"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"/>
    </LinearLayout>
</LinearLayout>

接下来创建一个适配器在com.llw.goodweather下新建一个WeatherForecastAdapter适配器

代码如下：

package com.llw.goodweather.adapter;

import androidx.annotation.Nullable;

import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;
import com.llw.goodweather.R;
import com.llw.goodweather.bean.WeatherForecastResponse;

import java.util.List;

/**
 * 天气预报列表展示适配器
 */
public class WeatherForecastAdapter extends BaseQuickAdapter<WeatherForecastResponse.HeWeather6Bean.DailyForecastBean, BaseViewHolder> {

    public WeatherForecastAdapter(int layoutResId, @Nullable List<WeatherForecastResponse.HeWeather6Bean.DailyForecastBean> data) {
        super(layoutResId, data);
    }

    @Override
    protected void convert(BaseViewHolder helper, WeatherForecastResponse.HeWeather6Bean.DailyForecastBean item) {
        helper.setText(R.id.tv_date, item.getDate())//日期
                .setText(R.id.tv_info, item.getCond_txt_d())//天气
                .setText(R.id.tv_low_and_height, item.getTmp_min() + "/" + item.getTmp_max() + "℃");//最低温和最高温
    }
}

④ 使用适配器进行数据展示

在MainActivity.java中增加

	List<WeatherForecastResponse.HeWeather6Bean.DailyForecastBean> mList;//初始化数据源
    WeatherForecastAdapter mAdapter;//初始化适配器
	/**
     * 初始化天气预报数据列表
     */
    private void initList() {
        mList = new ArrayList<>();//声明为ArrayList
        mAdapter = new WeatherForecastAdapter(R.layout.item_weather_forecast_list, mList);//为适配器设置布局和数据源
        LinearLayoutManager manager = new LinearLayoutManager(context);//布局管理,默认是纵向
        rv.setLayoutManager(manager);//为列表配置管理器
        rv.setAdapter(mAdapter);//为列表配置适配器
    }

然后在**initData()**方法中调用

返回值做处理

	//查询天气预报，请求成功后的数据返回
    @Override
    public void getWeatherForecastResult(Response<WeatherForecastResponse> response) {
        if (("ok").equals(response.body().getHeWeather6().get(0).getStatus())) {
            //最低温和最高温
            tvLowHeight.setText(response.body().getHeWeather6().get(0).getDaily_forecast().get(0).getTmp_min() + " / " +
                    response.body().getHeWeather6().get(0).getDaily_forecast().get(0).getTmp_max() + "℃");

            if (response.body().getHeWeather6().get(0).getDaily_forecast() != null) {
                List<WeatherForecastResponse.HeWeather6Bean.DailyForecastBean> data
                        = response.body().getHeWeather6().get(0).getDaily_forecast();
                mList.clear();//添加数据之前先清除
                mList.addAll(data);//添加数据
                mAdapter.notifyDataSetChanged();//刷新列表
            } else {
                ToastUtils.showShortToast(context, "天气预报数据为空");
            }
        } else {
            ToastUtils.showShortToast(context, response.body().getHeWeather6().get(0).getStatus());
        }
    }

运行

这样天气预报这个功能就完成了。接下来是生活指数。

7. 生活指数

生活指数就是一些生活建议，实现的不走其实和天气预报差不太多，但是比天气预报要简单一些，因为不需要列表显示，文本即可。

① 新增API接口

根据和风天气中的文档，得知生活指数接口为：

https://free-api.heweather.net/s6/weather/lifestyle?key=3086e91d66c04ce588a7f538f917c7f4&location=福田区

在网页上访问得到返回值，生成一个实体

代码如下：

package com.llw.goodweather.bean;

import java.util.List;

public class LifeStyleResponse {

    private List<HeWeather6Bean> HeWeather6;

    public List<HeWeather6Bean> getHeWeather6() {
        return HeWeather6;
    }

    public void setHeWeather6(List<HeWeather6Bean> HeWeather6) {
        this.HeWeather6 = HeWeather6;
    }

    public static class HeWeather6Bean {
        /**

            public void setTxt(String txt) {
                this.txt = txt;
            }
        }
    }
}

在ApiService中增加

代码如下：

	/**
     * 生活指数
     */
    @GET("/s6/weather/lifestyle?key=3086e91d66c04ce588a7f538f917c7f4")
    Call<LifeStyleResponse> getLifestyle(@Query("location") String location);

记得将key的值修改为自己的Key

② 修改订阅器

在WeatherContract新增生活指数订阅

		/**
         * 生活指数
         * @param context
         * @param location
         */
        public void lifeStyle(final Context context,String location){
            ApiService service = ServiceGenerator.createService(ApiService.class);
            service.getLifestyle(location).enqueue(new NetCallBack<LifeStyleResponse>() {
                @Override
                public void onSuccess(Call<LifeStyleResponse> call, Response<LifeStyleResponse> response) {
                    if(getView() != null){
                        getView().getLifeStyleResult(response);
                    }
                }

                @Override
                public void onFailed() {
                    if(getView() != null){
                        getView().getDataFailed();
                    }
                }
            });
        }

		//查询生活指数的数据返回
        void getLifeStyleResult(Response<LifeStyleResponse> response);

③ 修改布局

这次要展示的数据会比较多，所以布局的整体要用NestedScrollView包裹起来，变成一个·可以上下滑动的布局，布局修改后的代码如下(PS：为了不出现问题，这里我贴上全部的布局代码)：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:gravity="center"
    android:fitsSystemWindows="true"
    android:background="@drawable/pic_bg"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <!--相对布局-->
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
        <!--主要的布局文件-->
        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"

                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:contentInsetLeft="16dp"
                app:popupTheme="@style/AppTheme.PopupOverlay">
                <TextView

                    android:layout_height="wrap_content"
                    android:layout_gravity="center"
                    android:textSize="16sp"
                    android:textColor="#FFF"
                    android:text="城市天气" />
            </androidx.appcompat.widget.Toolbar>

            <!--NestedScrollView 里面只能包裹一个大的布局，
            当这个布局长度超出手机展示的部分就可以滚动，其中overScrollMode="never"
            的意思是隐藏掉滚动条到顶部和底部时的水波纹-->
            <androidx.core.widget.NestedScrollView
                android:overScrollMode="never"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
                <!--天气和所在城市 -->

                    android:layout_height="match_parent">
                    <!--天气状况-->
                    <TextView
                        android:paddingLeft="16dp"
                        android:paddingTop="12dp"

                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"/>
                    <!--温度-->
                    <LinearLayout
                        android:gravity="top|center_horizontal"

注释已经在代码中写好了，相信你看了就明白了。接下来就是数据返回的处理，和页面数据渲染显示。

④ 数据渲染显示

由于返回的数据可能会为空，为了使返回数据为空的时候程序不报错，这里要做判断，在模块的utils包下写一个工具类。

工具类代码如下：

package com.llw.mvplibrary.utils;

import android.os.Build;
import android.util.SparseArray;
import android.util.SparseBooleanArray;
import android.util.SparseIntArray;

import androidx.collection.SimpleArrayMap;

import java.lang.reflect.Array;
import java.util.Collection;
import java.util.Map;

/**

接下来调用方法请求生活指数

请求返回数据做处理：

	//查询生活指数，请求成功后的数据返回
    @Override
    public void getLifeStyleResult(Response<LifeStyleResponse> response) {
        if(("ok").equals(response.body().getHeWeather6().get(0).getStatus())){
            List<LifeStyleResponse.HeWeather6Bean.LifestyleBean> data = response.body().getHeWeather6().get(0).getLifestyle();
            if(!ObjectUtils.isEmpty(data)){
                for (int i = 0;i<data.size();i++){
                    if(("comf").equals(data.get(i).getType())){
                        tvComf.setText("舒适度："+data.get(i).getTxt());
                    }else if(("drsg").equals(data.get(i).getType())){
                        tvDrsg.setText("穿衣指数："+data.get(i).getTxt());
                    }else if(("flu").equals(data.get(i).getType())){
                        tvFlu.setText("感冒指数："+data.get(i).getTxt());
                    }else if(("sport").equals(data.get(i).getType())){
                        tvSport.setText("运动指数："+data.get(i).getTxt());
                    }else if(("trav").equals(data.get(i).getType())){
                        tvTrav.setText("旅游指数："+data.get(i).getTxt());
                    }else if(("cw").equals(data.get(i).getType())){
                        tvCw.setText("洗车指数："+data.get(i).getTxt());
                    }else if(("air").equals(data.get(i).getType())){
                        tvAir.setText("空气指数："+data.get(i).getTxt());
                    }
                }

            }else {
                ToastUtils.showShortToast(context, "生活指数数据为空");
            }
        }else {
            ToastUtils.showShortToast(context, response.body().getHeWeather6().get(0).getStatus());
        }
    }
