set datas

first step: create bean, must extends IBaseWeatherData

public interface IBaseWeatherData {

    int getHighDegree();

    int getLowDegree();
}

public class MyWeatherData implements IBaseWeatherData {

    public int highDegree;
    public int lowDegree;

    public MyWeatherData() {
    }

    public MyWeatherData(int highDegree, int lowDegree) {
        this.highDegree = highDegree;
        this.lowDegree = lowDegree;
    }

    @Override
    public int getHighDegree() {
        return highDegree;
    }

    @Override
    public int getLowDegree() {
        return lowDegree;
    }
}

second step: call WeatherView's method -- setDatas

 /**
     * 设置数据    T extends IBaseWeatherData
     * issue: 1.必须设置最低和最高的温度值，以及要展示的数据的position
     * 2.如果你需要在展示数据的时候，需要设置其它属性，那么这个方法必须在最后才能调用，否则控件不会重绘
     * 3.如果，确实需要动态改变属性，可以继承WeatherView，然后重写属性方法, 在调用父类方法之后，在调用  postInvalidate() 或者 invalidate()
     *
     * @param datas
     * @param highestDegree
     * @param lowestDegree
     * @param position
     */
    public void setDatas(List<T> datas, int highestDegree, int lowestDegree, int position) {
        this.datas = datas;
        this.highestDegree = highestDegree;
        this.lowestDegree = lowestDegree;
        this.position = position;
        postInvalidate();
    }

Create by xml

<cjh.weatherviewlibarary.WeatherView
                android:id="@+id/weatherView2"
                android:layout_width="80dp"
                android:layout_height="160dp"
                app:backgroundColor="@color/colorAccent"
                app:dotColor="@android:color/white"
                app:dotRadiu="5dp"
                app:highTxtColor="@color/colorPrimaryDark"
                app:istoday="true"
                app:lineColor="@color/colorPrimaryDark"
                app:lineStrokWidth="1dp"
                app:todayHighDotColor="#228989"
                app:todayHighTxtColor="@android:color/black"
                app:todayLowDotColor="#EAC100"
                app:todayLowTxtColor="@android:color/black"
                app:txtColor="@color/colorPrimary"
                app:txtSize="14sp"
                app:txtToBorder="10dp"
                app:txtToDot="9dp" />

Create by code

 @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new ViewHolder(new WeatherView<MyWeatherData>(context));
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        if (style == DEFAULT_WEATHERVIEW) {
            holder.weatherView.setHaveMiddleLine(true);
            holder.weatherView.setMiddleLineParams(1, Color.parseColor("#B8860B"));
        } else if (style == SETTING_WEATHERVIEW) {
            holder.weatherView.setWH(weatherViewW, weatherViewW * 2);
            holder.weatherView.setBackgroundColor(Color.parseColor("#22000000"));
            holder.weatherView.setDotParams(MainActivity.instance.dip2px(3), Color.parseColor("#FFFFFF"), Color.parseColor("#00FF00"));
            holder.weatherView.setTxtParams(MainActivity.instance.sp2px(12), Color.parseColor("#00ff00"), MainActivity.instance.dip2px(8), MainActivity.instance.dip2px(10));
            holder.weatherView.setLineParams(MainActivity.instance.dip2px(1), Color.YELLOW, Color.parseColor("#5F9EA0"));
            if (position == 1) {
                holder.weatherView.setToday(true);
                holder.weatherView.setTodayParams(MainActivity.instance.dip2px(3), Color.parseColor("#B8860B"), Color.parseColor("#8B1A1A"));
            } else
                holder.weatherView.setToday(false);
        }
        holder.weatherView.setDatas(datas, highestDegree, lowestDegree, position);
    }

important

only setData() invalidates WeatherView, if you hope other methods can invalidate WeatherView. You can create classes that extend WeatherView, and rewrite methods, all the WeatherView's methods are public and protected. like this:

public void setWH(){
    super.setWH();
    postInvalidate();
}
