我有一个产品列表，里面有一个带有CardViews的回收视图。每个CardView都有该产品的图像。如何在RecycleView中正确使用Picasso库
的问题是，我得到一个
"java.lang.OutOfMemoryError"
。 我认为是因为我在我的RecycleView适配器中使用了毕加索。
下面是代码：
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.squareup.picasso.Picasso;
import java.util.List;
import uk.co.something.R;
import uk.co.something.Product;
public class ProductListAdapter extends RecyclerView.Adapter<ProductListAdapter.ViewHolder> {
private List<Product> products;
private int rowLayout;
private Context appContext;
public ProductListAdapter(List<Product> products, int rowLayout, Context appContext) {
this.products = products;
this.rowLayout = rowLayout;
this.appContext = appContext;
}
@Override
public ProductListAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(rowLayout, viewGroup, false);
return new ProductListAdapter.ViewHolder(v);
}
@Override
public void onBindViewHolder(ProductListAdapter.ViewHolder viewHolder, int i) {
Product product = products.get(i);
Picasso.with(appContext).load(product.getUrl().getImage()).into(viewHolder.image);
Picasso.with(appContext).load(product.getRetailer().getIcon()).into(viewHolder.logo);
String productPrice = (product.getPrice().getDiscounted() == null || Double.parseDouble(product.getPrice().getDiscounted()) <= 0) ? product.getPrice().getCost() : product.getPrice().getDiscounted();
viewHolder.price.setText("\u00a3" + productPrice);
}
@Override
public int getItemCount() {
return products == null ? 0 : products.size();
}
static class ViewHolder extends RecyclerView.ViewHolder {
public ImageView image;
public ImageView logo;
public TextView price;
ViewHolder(View itemView) {
super(itemView);
image = (ImageView) itemView.findViewById(R.id.product_list_cardview_image);
logo = (ImageView) itemView.findViewById(R.id.product_list_cardview_logo);
price = (TextView) itemView.findViewById(R.id.product_list_cardview_price);
}
}
}
我得到的错误是这个：

在日志中说，问题就在这里：
View v = LayoutInflater.from(viewGroup.getContext()).inflate(rowLayout, viewGroup, false);
有人能帮我吗？
我认为你在布局xml中有一些大的图像。请展示它。 –
