8,287 Points@InjectView in HourAdapter
Is it possible for me to use @InjectView in my HourAdapter.HourViewHolder and if it is then where would I go about to add the ButterKnife.inject(this) call

package com.teamtreehouse.stormy.adapters;
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import com.teamtreehouse.stormy.R;
import com.teamtreehouse.stormy.weather.Hour;
import butterknife.ButterKnife;
import butterknife.InjectView;

public class HourAdapter extends RecyclerView.Adapter<HourAdapter.HourViewHolder> {
private Hour[] mHours;
private Context mContext;
public HourAdapter(Context context, Hour[] hours) {
mContext = context;
mHours = hours;
}
@Override
public HourViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.hourly_list_item, parent, false);
HourViewHolder hourViewHolder = new HourViewHolder(view);
return hourViewHolder;
}
@Override
public void onBindViewHolder(HourViewHolder holder, int position) {
holder.bindHour(mHours[position]);
}
@Override
public int getItemCount() {
return mHours.length;
}
public class HourViewHolder extends RecyclerView.ViewHolder
implements View.OnClickListener{
//public TextView mTimeLabel;
//public TextView mSummaryLabel;
//public TextView mTemperatureLabel;
//public ImageView mIconImageView;
@InjectView(R.id.timeLabel)
TextView mTimeLabel;
@InjectView(R.id.summaryLabel)
TextView mSummaryLabel;
@InjectView(R.id.temperatureLabel)
TextView mTemperatureLabel;
@InjectView(R.id.iconImageView)
ImageView mIconImageView;
public HourViewHolder(View itemView) {
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);
ButterKnife.inject(this, itemView);
itemView.setOnClickListener(this);
}
public void bindHour(Hour hour) {
mTimeLabel.setText(hour.getHour());
mSummaryLabel.setText(hour.getSummary());
mTemperatureLabel.setText(hour.getTemperature() + "");
mIconImageView.setImageResource(hour.getIconId());
}
@Override
public void onClick(View v) {
String time = mTimeLabel.getText().toString();
String temperature = mTemperatureLabel.getText().toString();
String summary = mSummaryLabel.getText().toString();
String message = String.format("At %s it will be %s and %s",
time,
temperature,
summary);
Toast.makeText(mContext, message, Toast.LENGTH_LONG).show();
}
}
}

2,682 PointsIt is not @InjectView anymore. It is now @Bind. Also, use ButterKnife.bind(this)
Kourosh Raeen
23,733 PointsHi Peter - @Bind is for a newer version of the Butterknife library. The one used for this course is an older version that uses @InjectView.

2,682 PointsOh good to know. Thank you.
