今天要來延續昨天的部分，首先來修改一下card_item的地方。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="120dp"
    android:layout_height="120dp"
    android:padding="5dp">
    <!--bg05與footprint04為牌的背面，腳印的部分可以改成其他的圖示。-->
    <ImageView
        android:id="@+id/photo_stroke"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/bg05" />

    <ImageView
        android:layout_centerInParent="true"
        android:layout_width="70dp"
        android:layout_height="60dp"
        android:background="@drawable/footprint04" />

    <!--下方有設置隱藏的屬性，在觸發翻轉的動作後會顯示之後再recyclerView中設置的圖片，並依照先前生成的數列來判斷要顯示的圖片為何。-->
    <ImageView
        android:layout_margin="3dp"
        android:id="@+id/photo_item"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="invisible" />

    <!--邊框。-->
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/bg06" />

    <!--未使用，用來標示元件位置-->
    <TextView
        android:id="@+id/info_text"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_alignParentEnd="true"
        android:layout_margin="5dp"
        android:background="@drawable/round07"
        android:gravity="center"
        android:textColor="#ffffff"
        android:visibility="gone"
        android:layout_alignParentRight="true" />

</RelativeLayout>

接下來是recyclerViewAdapter的部分，imageResource的地方為drawable中的圖示，用來後續顯示的圖示，在mData的部分為前面的數列，這裡會判斷數值為何，為1的話就會將該item位置的圖示設置為imageResource[0]，因為前面只會產生1~7的數值，所以這個部分就要再-1才會符合imageResource的內容。

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

    private String[] mData = new String[0];
    private LayoutInflater mInflater;
    private ItemClickListener mClickListener;
    private Integer[] imageResource = {R.drawable.red_card, R.drawable.orange_card, R.drawable.yellow_card,
            R.drawable.green_card, R.drawable.blue_card, R.drawable.indigo_card, R.drawable.purple_card};

    private int checkEvent;
    private int score;
    private int selectCard;
    private ArrayList<ImageView> ivNumberList;
    private ArrayList<Integer> selectList;
    private ArrayList<View> itemViewList;
    private Handler handler;
    private ArrayList<String> mImgRandomSelect;

    //選取狀態
    private int[] mSelectRegister;

    MyRecyclerViewAdapter(Context context, String[] data, int[] selectRegister) {
        handler = new Handler();
        selectList = new ArrayList<>();
        ivNumberList = new ArrayList<>();
        itemViewList = new ArrayList<>();
        mImgRandomSelect = new ArrayList<>();
        this.mInflater = LayoutInflater.from(context);
        this.mData = data;
        this.mSelectRegister = selectRegister;
    }


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

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.myTextView.setText(mData[position]);
        holder.mImageView.setImageResource(imageResource[Integer.parseInt(mData[position]) - 1]);
    }

    @Override
    public int getItemCount() {
        return mData.length;
    }

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView myTextView;
        ImageView mImageView;
        ImageView cardView;

        ObjectAnimator animator = ObjectAnimator.ofFloat(itemView, "rotationY", 0, 180);
        ObjectAnimator animatorBack = ObjectAnimator.ofFloat(itemView, "rotationY", 180, 360);

        ViewHolder(View itemView) {
            super(itemView);
            myTextView = itemView.findViewById(R.id.info_text);
            mImageView = itemView.findViewById(R.id.photo_item);
            cardView = itemView.findViewById(R.id.photo_stroke);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
        }
    }

    void setClickListener(ItemClickListener itemClickListener) {
        this.mClickListener = itemClickListener;
    }

    public interface ItemClickListener {
        void onItemClick(View view, int position, int score);
    }
}

通過上面的操作，已經完成所有元件的顯示，明天要進入到點擊的部分來判斷可能選擇的結果與動畫的撥放。
