SharedPreferences within a fragment - android-fragments

Question

Once the user selects an item from a list in another fragment it brings you to this fragment. And I'm having issues trying to save the users rating that was selected. when the user goes back it should be the same rating that was previously selected.
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import android.support.v4.app.Fragment;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.RatingBar;
import android.widget.TextView;
import java.util.Arrays;
public class infoFragment extends Fragment {
TextView degrees;
ImageView image;
String stringtext;
String [] hold;
private RatingBar rating;
SharedPreferences wmbPreference1;
SharedPreferences.Editor editor;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.info_layout, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState){
image = (ImageView) view.findViewById(R.id.imageView);
why can i not use "this"
rating =((RatingBar) view.findViewById(R.id.ratingBar)).setOnRatingBarChangeListener(this);
wmbPreference1 = PreferenceManager.getDefaultSharedPreferences(this);
degrees =(TextView)view.findViewById(R.id.textView);
}
public void onRatingChanged(RatingBar ratingBar, float rating,
boolean fromTouch) {
final int numStars = ratingBar.getNumStars();
editor = wmbPreference1.edit();
editor.putInt("numStars", numStars);
editor.commit();
int ratings = wmbPreference1.getInt("numStars", 0);
}
public void setText(final String string) {
Character[] hold;
if(string == "apple"){
String[] word = { " A \n", "B\n" };
degrees.setText(Arrays.toString(word).replaceAll("\\[|\\]", ""));;
image.setImageResource(R.drawable.APPLE);
}
Should I call onRatingChanged within the conditional statement for it to save?
if(string == "orange"){
String[] word = { " AA\n", "AB\n" };
degrees.setText(Arrays.toString(word).replaceAll("\\[|\\]", ""));;
image.setImageResource(R.drawable.bruce);
}
}
public void sentText(){
new MyTask().execute();
}
private class MyTask extends AsyncTask<String, String, String> {
#Override
protected String doInBackground(String... strings) {
Bundle b = getArguments();
stringtext = b.getString("text");
return null;
}
protected void onPostExecute(String result){setText(stringtext);
}
}
}

Your Fragment should implement OnRatingBarChangeListener:
public class infoFragment extends Fragment implements OnRatingBarChangeListener
The other thing is that setOnRatingChangeListener does not return a value, so you can't assign the return value to rating as you did.
You should do:
rating = (RatingBar) view.findViewById(R.id.ratingBar);
rating.setOnRatingBarChangeListener(this);
