RecyclerView Adapter in android - android-recyclerview

Question

In #override onBindViewHolder method, I get an error message:
Non-static field 'mWeatherTextView' cannot be referenced from a
static context
I checked for all possible errors but didn't find any, even my code is similar to the solution provided but there is no error showing for the solution provided.
package com.example.android.sunshine;
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.TextView;
public class ForecastAdapter extends
RecyclerView.Adapter<ForecastAdapter.ForecastAdapterViewHolder> {
private String[] mWeatherData;
public ForecastAdapter(){}
public class ForecastAdapterViewHolder extends RecyclerView.ViewHolder{
public final TextView mWeatherTextView;
public ForecastAdapterViewHolder(View view){
super(view);
mWeatherTextView =(TextView)view.findViewById(R.id.tv_weather_data);
}
}
#Override
public ForecastAdapterViewHolder onCreateViewHolder(ViewGroup parent, int
viewType) {
Context context = parent.getContext();
int layoutIdForListItem = R.layout.forecast_list_item;
boolean shouldAttachToParentImmediately = false;
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(layoutIdForListItem,
parent,shouldAttachToParentImmediately);
return new ForecastAdapterViewHolder(view);
}
#Override
public void onBindViewHolder(ForecastAdapterViewHolder holder, int position)
{
String weatherForThisDay = mWeatherData[position];
ForecastAdapterViewHolder.mWeatherTextView.setText(weatherForThisDay);
_**/* error message says "Non-static field 'mWeatherTextView' cannot be referenced from a static context" */**_
}
#Override
public int getItemCount() {
if(mWeatherData == null) return 0;
return mWeatherData.length;
}
}

Answer 1

In onBindViewHolder, you will always use the holder that has been passed as an argument. So change ForecastAdapterViewHolder to holder in setText line.
package com.example.android.sunshine;
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.TextView;
public class ForecastAdapter extends
RecyclerView.Adapter<ForecastAdapter.ForecastAdapterViewHolder> {
private String[] mWeatherData;
public ForecastAdapter(){}
public class ForecastAdapterViewHolder extends RecyclerView.ViewHolder{
public final TextView mWeatherTextView;
public ForecastAdapterViewHolder(View view){
super(view);
mWeatherTextView =(TextView)view.findViewById(R.id.tv_weather_data);
}
}
#Override
public ForecastAdapterViewHolder onCreateViewHolder(ViewGroup parent, int
viewType) {
Context context = parent.getContext();
int layoutIdForListItem = R.layout.forecast_list_item;
boolean shouldAttachToParentImmediately = false;
LayoutInflater inflater = LayoutInflater.from(context);
View view = inflater.inflate(layoutIdForListItem,
parent,shouldAttachToParentImmediately);
return new ForecastAdapterViewHolder(view);
}
#Override
public void onBindViewHolder(ForecastAdapterViewHolder holder, int position)
{
String weatherForThisDay = mWeatherData[position];
holder.mWeatherTextView.setText(weatherForThisDay);
_**/* error message says "Non-static field 'mWeatherTextView' cannot be referenced from a static context" */**_
}
#Override
public int getItemCount() {
if(mWeatherData == null) return 0;
return mWeatherData.length;
}
}

Answer 2

Instead of ForecastAdapterViewHolder.mWeatherTextView.setText(weatherForThisDay);
use
holder.mWeatherTextView.setText(weatherForThisDay);
