ViewFlipper à l'intérieur RecyclerView ViewHolder

Question

J'utilise viewFlipper dans RecyclerView Adapter Item, mais il fonctionne de façon anormale, comme si je retournais une vue, puis que je la fais défiler, l'autre vue du recyclerView est également retournée. S'il vous plaît me aider à résoudre ce problème ..

code

Pour RecyclerView Adaptateur:

public class SelfStudyAdapter extends RecyclerView.Adapter<SelfStudyAdapter.ViewHolder> { 
    private BaseActivity context; 
    private LayoutInflater inflater; 
    private List<SelfStudyModel> dataList = new ArrayList<>(); 
    private AdapterClickListener adapterClickListener; 

    public SelfStudyAdapter(BaseActivity context, List<SelfStudyModel> dataList) { 
     this.context = context; 
     this.dataList = dataList; 
     inflater = LayoutInflater.from(context); 
    } 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View view = inflater.inflate(R.layout.item_new_learning_path, parent, false); 
     return new ViewHolder(view); 
    } 

    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 
     SelfStudyModel data = dataList.get(position); 

     int getLastPercentage = Math.round(data.getLastTestPercentage()); 
     holder.txtChapter.setText(data.getChapter().getName()); 
     holder.txtChapterNo.setText(context.getResources().getString(R.string.chapter) + " " + data.getChapter().getNumber()); 
     holder.txtChapter2.setText(data.getChapter().getName()); 
     holder.txtChapterNo2.setText(context.getResources().getString(R.string.chapter) + " " + data.getChapter().getNumber()); 
     if (getLastPercentage > 0) { 
      holder.txtMarksPercentage2.setText(String.valueOf(getLastPercentage)); 
      holder.progressMarksPercentage2.setProgress(getLastPercentage); 
      holder.flProgressBar2.setVisibility(View.VISIBLE); 
      holder.txtLastPercentage2.setVisibility(View.VISIBLE); 
      holder.txtMarksPercentage2.setVisibility(View.VISIBLE); 
      holder.progressMarksPercentage2.setVisibility(View.VISIBLE); 
     } else { 
      holder.flProgressBar2.setVisibility(View.INVISIBLE); 
      holder.txtLastPercentage2.setVisibility(View.INVISIBLE); 
      holder.txtMarksPercentage2.setVisibility(View.INVISIBLE); 
      holder.progressMarksPercentage2.setVisibility(View.INVISIBLE); 
     } 

     holder.btnLearning2.setText(data.getLqViewed() + "/" + data.getLqTotal()); 
     holder.txtPqViewed.setText(String.valueOf(data.getWqViewed())); 
     holder.txtPqTotal.setText("/" + data.getWqTotal()); 
     holder.btnSummary2.setText(data.getSummaryTimeSpent() + " min"); 
     holder.txtPqUp.setText(String.valueOf(data.getFlaggedWqTotal())); 
     holder.txtPqDown.setText(String.valueOf(data.getNeedHelpWqTotal())); 
    } 

    @Override 
    public int getItemCount() { 
     return dataList.size(); 
    } 

    public AdapterClickListener getAdapterClickListener() { 
     return adapterClickListener; 
    } 

    public void setAdapterClickListener(AdapterClickListener adapterClickListener) { 
     this.adapterClickListener = adapterClickListener; 
    } 

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 

     protected ViewFlipper viewFlipper;

      btnSummary2.setOnClickListener(this);

      itemView.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        AnimationFactory.flipTransition(viewFlipper, AnimationFactory.FlipDirection.TOP_BOTTOM); 
       } 
      }); 
     } 

     @Override 
     public void onClick(View v) { 
      if (getAdapterClickListener() != null) { 
       getAdapterClickListener().onClick(getAdapterPosition(), v); 
      } 
     } 
    } 
}

J'ai eu un problème similaire en utilisant ViewSwitcher. Si vous voulez recycler toujours à la première vue de l'enfant, vous pouvez définir dans votre onBindViewHolder:

resetFlipper(holder.viewFlipper); 

Ensuite, créez une fonction d'aide pour mettre l'enfant sans déclencher l'animation:

private void resetFlipper(ViewFlipper vf){ 
    Animation inAnimation = vf.getInAnimation(); 
    Animation outAnimation = vf.getOutAnimation(); 
    vf.setInAnimation(null); 
    vf.setOutAnimation(null); 
    vf.setDisplayedChild(0); 
    vf.setInAnimation(inAnimation); 
    vf.setOutAnimation(outAnimation); 
}
