java - 使用 RecyclerView 和 Picasso 问题处理大量图像

Question

更新
我发现了我的问题。我正在尝试使用 RecyclerView 处理大量图像(.webp 格式的 770 个图像，图像总大小为 10mb)，但它显示内存不足错误。
如何解决这个问题？
我正在使用 picasso 加载图像

抛出 OutOfMemoryError“无法分配具有 107504 个可用字节和 104KB 的 810076 字节分配，直到 OOM”

旧
如果列表大小小于 100 没有问题，如何使用回收器 View 加载 700 项。每个项目都包含 webp 格式的图像
我正在尝试这段代码，它抛出内存不足错误并使应用程序崩溃。如何解决这个错误？
(它包含 700 个图像，全部为 webp 格式，此代码位于具有网格布局的 recyclerview 中)

 InputStream ins = null;

                try {
                    ins = mContext.getAssets().open(mData.get(position).getImagename()+".webp");
                    Bitmap bitmap = BitmapFactory.decodeStream(ins);
                    holder.image.setImageBitmap(bitmap);
                } catch (final IOException e) {
                    e.printStackTrace();
                } finally {
                    if (ins != null)
                        try {
                            ins.close();
                        } catch (IOException e) { }
                }

我的 list 文件

<application
        android:name=".App"
        android:allowBackup="false"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:supportsRtl="true"
        tools:replace="android:allowBackup"
        android:theme="@style/AppTheme">

更新我用 Picasso 替换，它在 2GB RAM 的智能手机中工作，在 500MB 的智能手机中崩溃，有时在 1GB RAM 的智能手机中也崩溃
添加 picasso 后，现在图像加载需要 5 秒

更新了新代码 但问题没有解决

这是我用来加载的代码

try {
                       List<Millafish_profile> list = mDatabaseManager.getAll();
                       for (int i = 0; i < list.size(); i++) {
                           final int finalI = i;//"@drawable/" +
                           String uri = list.get(i).getPic().replace("’", "_").replace(".jpg", "").replace(".png", "").replace("-", "_");  // where myresource (without the extension) is the file
                           // Log.i("uri_"+i,uri+"");
                           Millafish_profile millafish_profile = list.get(i);//mDatabaseManager.getprofile(mDatabaseManager.getallfishname().get(finalI));
                           millafish_profile.setImageuri(uri.toLowerCase());
                           millafish_profileList.add(millafish_profile);
                           //if(i==20)break;

                           {
                               //adapter.notifyItemChanged(i);
                               //(millafish_profileList.size());
                           }

                       }
                       adapter.notifyDataSetChanged();
                       millafish_profileList_org = new ArrayList<>();
                       millafish_profileList_org.addAll(millafish_profileList);

                   }catch (Exception e){
                       Log.e("homepage",e.getMessage()+"");
                   }

Answer 1

删除 Picasso 并使用 Glide

Glide.with(mContext).load(Uri.parse("file:///android_asset/"+mData.get(position).getImageuri()+".webp"))
                                .thumbnail(0.5f)

                                .into(holder.image);
