因此，我试图创建一个挑战游戏，你可以有2个选项来选择，我有两个卡在回收视图设置视图设置，我将如何改变他们的价值观，以获得一个新的挑战与点击按钮从主要活动，如果用户想要一个新的挑战？我使用sqlite数据库随机获取每一场战斗的数据。
我的onbindviewholder

@Override
    public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {
        SQLiteDatabase sqLiteDatabase = faceMashDatabaseHelper.getReadableDatabase();
        cursor = sqLiteDatabase.query("images", new String[]{"id","filename","name"},null,null,null,null,null);
        MyViewHolder myViewHolder = (MyViewHolder) holder;
        int position1 = (int)(Math.random()*(faceMashDatabaseHelper.getCount()-0+1)+0);
        cursor.moveToPosition(position1);
        String filename = cursor.getString(cursor.getColumnIndex("filename"));
        String name = cursor.getString(cursor.getColumnIndex("name"));
        CardView cardView = myViewHolder.getCardView();
        ImageView imageView = (ImageView) cardView.findViewById(R.id.imageView);
        TextView nameView = (TextView) cardView.findViewById(R.id.nameView);
        nameView.setText(name);
        File file = context.getFileStreamPath(filename);
        if(file.exists()){
            Bitmap bitmap = BitmapFactory.decodeFile(file.getAbsolutePath());
            imageView.setImageBitmap(bitmap);

        }
        cardView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String name = nameView.getText().toString();
                listener.onClick(position,name);
            }
        }); //This on click is for the card views themselves.

    }

我的onclick在当前时刻，我正在使用一个工具栏选项

case R.id.newbattle:
faceMashAdapter.notifyDataSetChanged();
