Что вы думаете о переворачивании карт переработчика?

/ 15 февраля 2019

У меня есть Recyclerview с элементами cardview, я хочу показать только один элемент в моем recyclerview, который находится перед моей картой.когда я нажимал на лицевую сторону карты, это переворачивал карту и отображал заднюю карту.В этом макете у меня есть кнопка, чтобы показать следующую карту тоже.Мой код указан ниже, но проблема в том, что когда я нажимаю на первую карту, она переворачивается и отображается обратно, но карта 4-ая тоже перевернулась, как я могу это исправить?

Основная активность 

public class ReviewActivity extends AppCompatActivity {

Toolbar toolbar;

private ReviewAdapterRecyclerView adapter;
private LinearLayoutManager mLayoutManager;
private RecyclerView recyclerView;
private ArrayList<Card> cards;
// Database Helper
MyDatabaseHelper db;

public CardView f,b;
public LinearLayout dialog;
private boolean isShowingBack = false;
public ImageButton nxt;
public int cPos = 1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_review);

    setupToolbar();

    assert getSupportActionBar() != null;
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    db = new MyDatabaseHelper(getApplicationContext());

    cards = db.getAllCards();

    recyclerView = (RecyclerView) findViewById(R.id.recycler_review);
    recyclerView.setHasFixedSize(true);
    //mLayoutManager = new LinearLayoutManager(this);
    mLayoutManager = new SnappingLinearLayoutManager(getApplicationContext());
    //recyclerView.setLayoutManager(new SnappingLinearLayoutManager(this,VERTICAL,false));
    recyclerView.setLayoutManager(new SnappingLinearLayoutManager(getApplicationContext()));
    recyclerView.setLayoutManager(mLayoutManager);

    adapter = new ReviewAdapterRecyclerView(cards, this);

    recyclerView.setAdapter(adapter);
    adapter.notifyDataSetChanged();
    dialog = (LinearLayout) findViewById(R.id.review_dialog);

    recyclerView.addOnItemTouchListener(
            new RecyclerItemClickListener(getApplicationContext(),recyclerView, new RecyclerItemClickListener.OnItemClickListener() {
                @Override
                public void onItemClick(View view, int position) {
                    if (findViewById(R.id.card_front).getVisibility()==GONE) {
                        b = (CardView) view.findViewById(R.id.card_front);
                        f = (CardView) view.findViewById(R.id.card_back);
                        dialog.setVisibility(View.GONE);
                    } else {
                        f = (CardView) view.findViewById(R.id.card_front);
                        b = (CardView) view.findViewById(R.id.card_back);
                        dialog.setVisibility(View.VISIBLE);
                   }
                    f.animate().rotationX(-90).setDuration(300).setListener(new AnimatorListenerAdapter() {
                        @Override
                        public void onAnimationEnd(Animator animation) {
                            super.onAnimationEnd(animation);
                            f.setVisibility(View.GONE);
                            b.setRotationX(90);
                            b.setVisibility(View.VISIBLE);
                            b.animate().rotationX(0).setDuration(300).setListener(null);
                        }
                    });
                    isShowingBack=!isShowingBack;
                }

                @Override
                public void onLongItemClick(View view, int position) {
                    // do whatever
                }
            })
    );
    nxt = (ImageButton) findViewById(R.id.showNextCard);
    nxt.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            //myRecyclerView.getLayoutManager().scrollToPosition(cPos++);
            if(cPos==cards.size()){
                Toast.makeText(ReviewActivity.this, "finish", Toast.LENGTH_SHORT).show();
                finish();
            }
            isShowingBack = !isShowingBack;
            recyclerView.getLayoutManager().scrollToPosition(cPos++);
            dialog.setVisibility(View.GONE);
        }
    });
}

Адаптер Recyclerview 

public class ReviewAdapterRecyclerView extends RecyclerView.Adapter<ReviewAdapterRecyclerView.MyViewHolder> {

private ArrayList<Card> cardList;
private Context ctx;

public ReviewAdapterRecyclerView(ArrayList<Card> cards, Context context) {
    this.cardList = cards;
    this.ctx = context;
}

class MyViewHolder extends RecyclerView.ViewHolder {
    public CardView fr,bk;
    public TextView txtFront, txtBack, txtFrontHeader, txtBackHeader;
    public View view;

    public MyViewHolder(final View itemView) {
        super(itemView);
        view=itemView;
        txtFrontHeader = (TextView) itemView.findViewById(R.id.front_header_txt);
        txtBackHeader = (TextView) itemView.findViewById(R.id.back_header_txt);
        txtFront = (TextView) itemView.findViewById(R.id.display_card_front_text);
        txtBack = (TextView) itemView.findViewById(R.id.display_card_back_text);
        fr=(CardView) itemView.findViewById(R.id.card_front);
        bk=(CardView) itemView.findViewById(R.id.card_back);
    }
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    LayoutInflater inflater=LayoutInflater.from(parent.getContext());
    View view = inflater.inflate(R.layout.cards_review_layout, parent, false);
    return new MyViewHolder(view);
}

@Override
public void onBindViewHolder(final MyViewHolder holder, final int position) {

    final Card card = cardList.get(position);
    String s = ctx.getString(R.string.box);
    holder.txtFrontHeader.setText(card.getGroupName() + " " + card.getId());
    holder.txtBackHeader.setText(s + " " + boxString(card.getBoxNo()));
    holder.txtFront.setText(card.getFront());
    holder.txtBack.setText(card.getRear());
}

private String boxString(int x) {
    String s = "";
    switch (x) {
        case 1:
            s = ctx.getString(R.string.first);
            break;
        case 2:
            s = ctx.getString(R.string.second);
            break;
        case 3:
            s = ctx.getString(R.string.third);
            break;
        case 4:
            s = ctx.getString(R.string.fourth);
            break;
        case 5:
            s = ctx.getString(R.string.fifth);
            break;

    }
    return s;
}

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