我正在开发天气android应用，我想以相应的说明将天气情况显示为图标，但图像视图未显示网址图标 在我的终点以下
public interface ApiService {
@GET("/v1/search.json?")
// return type is List
Call<List<Weather>> getWeather(
@Query("key") String mKey,
@Query("q") String mCityName);
@GET("v1/forecast.json")
Call<ForecastEndingPoint> forecast(
@Query("key") String key,
@Query("q") String condition,
@Query("days") int days
);
}
在我已声明API URL的WeatherClient.java类下面
public class WeatherClient {
private static final String ROOT_URL = "http://api.apixu.com";
/**
* Get Retrofit Instance
*/
private static Retrofit getRetrofitInstance() {
return new Retrofit.Builder()
.baseUrl(ROOT_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
/**
* Get API Service
*
* @return API Service
*/
public static ApiService getApiService() {
return getRetrofitInstance().create(ApiService.class);
}
}
在我的ConditionAdapter.java类下，该类已实现了天气描述和图标
public class ConditionAdapter extends RecyclerView.Adapter<ConditionAdapter.CustomViewHolder> {
public List<ForecastEndingPoint> forecastList;
public Context context;
public Context picassoContext;
private final int imageWidthPixels = 1024;
private final int imageHeightPixels = 768;
public ConditionAdapter(List<ForecastEndingPoint> forecastList, Context context, Context picassoContext) {
this.forecastList = forecastList;
this.context = context;
this.picassoContext = picassoContext;
}
@Override
public ConditionAdapter.CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.weather_list, parent, false);
return new CustomViewHolder(itemView);
}
@Override
public void onBindViewHolder(CustomViewHolder holder, int position) {
// String icon = condition1.getCurrent().getCondition().getIcon();
// int r = map.get(icon);
ForecastEndingPoint forecastEndingPoint = forecastList.get(position);
holder.weatherDescription.setText((String.valueOf(forecastEndingPoint.getCurrent().getCondition().getText())));
// Condition condition = new Condition();
Picasso.get().load(forecastEndingPoint.getCurrent().getCondition().getIcon())
.fit().centerCrop().into(holder.weatherIcon);
// @@ -80,7 +80,7 @@ public int getItemCount() {

public class CustomViewHolder extends RecyclerView.ViewHolder {

weatherDescription = view.findViewById(R.id.weatherDescription);
// weatherDescription = (TextView)view.findViewById(R.id.weatherDescription);

}
}
在我实现了城市名称和地区的WeatherAdapter类下面
public class WeatherAdapter extends RecyclerView.Adapter<WeatherAdapter.CustomViewHolder> {
private List<Weather> weathers;
private List<Condition> conditionList;
private Context context;
public WeatherAdapter(List<Weather> weathers) {

答案 0 :(得分：0)
您需要更正图标位置的网址。
final String icon = forecastEndingPoint.getCurrent()
.getCondition().getIcon().replace("//", "");
Picasso.get().load(icon)
.fit().centerCrop().into(holder.weatherIcon);
如果Picasso缺少协议，则可能需要添加。
final String icon = "http:" + forecastEndingPoint.getCurrent()
.getCondition().getIcon();
Picasso.get().load(icon)
.fit().centerCrop().into(holder.weatherIcon);
