嗨,我想知道为什么我得到这个错误说它找不到符号bindHour当我有它在页面底部声明?任何帮助将非常感激,非常感谢你提前!!

public class HourViewHolder extends RecyclerView.ViewHolder {

super(itemView);
mTimeLabel = (TextView) itemView.findViewById(R.id.timeLabel);
mSummaryLabel = (TextView) itemView.findViewById(R.id.summaryLabel);
mTemperatureLabel = (TextView) itemView.findViewById(R.id.temperatureLabel);
mIconImageView = (ImageView) itemView.findViewById(R.id.iconImageView);
}
public void bindHour(Hour hour) {
mTimeLabel.setText(hour.getHour());
mSummaryLabel.setText(hour.getSummary());
mTemperatureLabel.setText(hour.getTemperature() + "");
mIconImageView.setImageResource(hour.getIconId());
}
}
}
,这是我的logcat,当我试图运行它。它似乎有一个问题与bindHour在OnBindViewHolder方法?

标准是:
public class HourAdapter extends RecyclerView.Adapter<HourAdapter.HourViewHolder>
那么你的方法签名变成:
public HourViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
public void onBindViewHolder(HourViewHolder holder, int position)
它不是为RecyclerView.ViewHolder定义的。你需要先将holder转换为一个HourViewHolder
