Comment accéder à l'évaluation de la barre d'évaluation dans recyclerview

Question

J'utilise la vue carte et la vue recycleur avec pied de page. Il s'agit d'un formulaire d'enquête avec une vue de texte montrant les questions et la barre de notation. Il y aura plus d'une question et le pied de page aura textarea et soumettre le bouton. J'ai essayé d'obtenir la note de la barre de cotation en cliquant sur le bouton Soumettre, mais j'obtiens la cote de la dernière carte de la recyclview. Voici le code que j'utilise pour obtenir les notes. La méthode submitResponse() est appelée en cliquant sur le bouton Soumettre et j'écris le code pour obtenir la note de tous les cardview dedans.

public class SurveyDetailsAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> { 


private static final int FOOTER_VIEW = 1; 
static List<SurveyQuestions> surveyQuestionses= new ArrayList<>(); 
public static Activity ctx; 

public static ScheduleData scheduleData; 
public static SurveyDetailsViewHolder vh; 

public SurveyDetailsAdapter(List<SurveyQuestions> surveyQuestionses,Activity ctx,ScheduleData scheduleData) { 
    this.surveyQuestionses = surveyQuestionses; 
    this.ctx=ctx; 
    this.scheduleData=scheduleData; 
} 

@Override 
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 

     View v; 

    if (viewType == FOOTER_VIEW) { 
     v = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_footer, parent, false); 
     FooterViewHolder vh = new FooterViewHolder(v); 
     return vh; 
    } 
    v = LayoutInflater.from(parent.getContext()).inflate(R.layout.survey_details_view_layout, parent, false); 
    SurveyDetailsViewHolder pvh = new SurveyDetailsViewHolder(v); 
    return pvh; 

} 

@Override 
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 

    // holder.time.setText(String.valueOf(scheduleData.get(position).starttime+"-"+String.valueOf(scheduleData.get(position).endtime))); 
    // holder.title.setText(String.valueOf(scheduleData.get(position).title)); 
    // holder.date.setText(String.valueOf(scheduleData.get(position).date)); 

    try { 
     if (holder instanceof SurveyDetailsViewHolder) { 
      vh = (SurveyDetailsViewHolder) holder; 
      vh.question.setText(surveyQuestionses.get(position).question); 

      // vh.bindView(position); 


     } else if (holder instanceof FooterViewHolder) { 
      FooterViewHolder vh = (FooterViewHolder) holder; 

     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 



@Override 
public int getItemCount() { 
    if (surveyQuestionses == null) { 
     return 0; 
    } 
    if (surveyQuestionses.size() == 0) { 
     return 1; 
    } 

    return surveyQuestionses.size()+1; 
} 

// Now define getItemViewType of your own. 
@Override 
public int getItemViewType(int position) { 
    if (position ==surveyQuestionses.size()) { 
     // This is where we'll add footer. 
     return FOOTER_VIEW; 
    } 

    return super.getItemViewType(position); 
} 

@Override 
public void onAttachedToRecyclerView(RecyclerView recyclerView) { 
    super.onAttachedToRecyclerView(recyclerView); 
} 

public class FooterViewHolder extends RecyclerView.ViewHolder { 
    EditText comments; 
    MainActivity mainActivity = (MainActivity) ctx; 


    public FooterViewHolder(final View itemView) { 
     super(itemView); 

     itemView.findViewById(R.id.submit).setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       // Do whatever you want on clicking the item 

       submitResponse(); 
       Toast.makeText(mainActivity.getApplicationContext(),"Thank you.", Toast.LENGTH_SHORT).show(); 
       mainActivity.switchContent(Surveys.FRAGMENT_TAG); 
      } 
     }); 
     } 

    public void submitResponse(){ 

     comments=(EditText)itemView.findViewById(R.id.comments); 

     List<String> rat= new ArrayList<String>(); 

     for(int i=0;i<surveyQuestionses.size();i++){ 
      rat.add(String.valueOf(SurveyDetailsViewHolder.ratingBar.getRating())); 
     } 

     for(int j=0;j<rat.size();j++){ 
      Toast.makeText(mainActivity.getApplicationContext(),rat.get(0).toString()+rat.get(1).toString()+rat.get(2).toString(), Toast.LENGTH_SHORT).show(); 
     } 

    } 

    } 

// So you're done with adding a footer and its action on onClick. 
// Now set the default ViewHolder for NormalViewHolder 

public static class SurveyDetailsViewHolder extends RecyclerView.ViewHolder { 
    public static CardView cv; 
    TextView question; 
    public static RatingBar ratingBar; 
    SurveyDetailsViewHolder(View itemView) { 
     super(itemView); 

     cv = (CardView) itemView.findViewById(R.id.card_view_layout); 
     question = (TextView) itemView.findViewById(R.id.que1); 
     ratingBar = (RatingBar) itemView.findViewById(R.id.ratingBar); 




    } 
} 
} 

Answer 1

Vous avez SurveyQuestion POJO. Ajouter votre POJO nouveau champ, vous pouvez l'appeler note

public class SurveyQuestion { 
    public float rating = 0.0f; //this will be default value, if user has not rate, this value will be passed 
    // Your other variabes, constructors etc. 
} 

Ensuite, vous devez écouter vos changements de barre de note sur votre RecyclerView Adaptateur

public static class SurveyDetailsViewHolder extends RecyclerView.ViewHolder { 
public static CardView cv; 
    TextView question; 
    public static RatingBar ratingBar; 

    SurveyDetailsViewHolder(View itemView) { 
     super(itemView); 
     cv = (CardView) itemView.findViewById(R.id.card_view_layout); 
     question = (TextView) itemView.findViewById(R.id.que1); 
     ratingBar = (RatingBar) itemView.findViewById(R.id.ratingBar); 
     ratingBar .setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() { 
     @Override 
     public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) { 
      surveyQuestionses.get(getPosition()).rating = ratingBar.getRating(); 
     } 
    }); 

    } 
} 

Enfin sur votre méthode submitResponse() vous pouvez accéder à vos notes de votre surveyQuestionses liste.

public void submitResponse(){ 

    comments=(EditText)itemView.findViewById(R.id.comments); 

    List<String> rat= new ArrayList<String>(); 

    for(int i=0;i<surveyQuestionses.size();i++){ 
     rat.add(String.valueOf(surveyQuestionses.rating)); 
    } 
}
