RecyclerView changes the height when scrolled how to solve this?

Question

I'm using a recyclerview in order to show some photos of products, when I open the app it works amazing but when I scroll, the height of each card gets a lot bigger and then when I open the keyboard the height gets it's best size and then when I scroll, it gets this bad size again, I can't figure out how to fix that.

xml

<android.support.v7.widget.RecyclerView
   android:id="@+id/recycler_view"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:clipToPadding="false"
   android:scrollbars="vertical" />

Adapter

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

private Context mContext;
private List<Product> productList;

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.product_card, parent, false);

    return new ProductsAdapter.ViewHolder(itemView);

}

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

    Product album = productList.get(position);
    holder.title.setText(album.getName());
    holder.price.setText(album.getPrice() + " DZA");

    // loading album cover using Glide library
    Glide.with(mContext).load(album.getThumbnail()).into(holder.thumbnail);

    holder.overflow.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            showPopupMenu(holder.overflow);
        }
    });
}

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

public class ViewHolder extends RecyclerView.ViewHolder{
    public TextView title, price;
    public ImageView thumbnail, overflow;

    public ViewHolder (View itemView){
        super (itemView);
        title = (TextView) itemView.findViewById(R.id.title);
        price = (TextView) itemView.findViewById(R.id.count);
        thumbnail = (ImageView) itemView.findViewById(R.id.thumbnail);
        overflow = (ImageView) itemView.findViewById(R.id.overflow);
    }
}

public ProductsAdapter(Context mContext, List<Product> productList) {
    this.mContext = mContext;
    this.productList = productList;
}
private void showPopupMenu(View view) {
    // inflate menu
    PopupMenu popup = new PopupMenu(mContext, view);
    MenuInflater inflater = popup.getMenuInflater();
    inflater.inflate(R.menu.menu_product_card, popup.getMenu());
    popup.setOnMenuItemClickListener(new MyMenuItemClickListener());
    popup.show();
}
class MyMenuItemClickListener implements PopupMenu.OnMenuItemClickListener {

    public MyMenuItemClickListener() {
    }

    @Override
    public boolean onMenuItemClick(MenuItem menuItem) {
        switch (menuItem.getItemId()) {
            case R.id.action_add_favourite:
                Toast.makeText(mContext, "Add to favourite", Toast.LENGTH_SHORT).show();
                return true;
            case R.id.action_play_next:
                Toast.makeText(mContext, "Play next", Toast.LENGTH_SHORT).show();
                return true;
            default:
        }
        return false;
    }
}
}

Answer 1

I fixed the problem, it was all about wrap_content and match_parent I made a very stupid mistake sorry everyone. I changed match_parent to wrap_content in cardview and this works perfectly now. Thanks guys.
