这是我的recyclerView适配器类。我想从这里显示图像头像。我不明白怎么做。我尝试了什么 -

Glide文档但不理解
在stackoverflow中，每个人都使用之前定义的静态URL。但我的网址是随机生成的以及如何使用该网址
我尝试使用位图。但无法弄明白。怎么做？

Answer 1

您可以这样记录，

Uri uri = Uri.parse(Uri.parse(data.get(position).getUserInfo().getAvatar()).getPath());
Glide.with(context).load(uri).into(holder.imV);

Answer 2

您可以使用Picasso库。使用Picasso加载图片非常简单，您可以这样做：

Uri imageURI = Uri.parse(Uri.parse(data.get(position).getUserInfo().getAvatar()).getPath());
Picasso.with(context).load("imageURI").into(holder.imV);

在他们的website中，您可以获得所有细节。

另一个库是Glide。您也可以使用Glide来加载图片。

您还可以使用Glide：

Uri imageURI = Uri.parse(Uri.parse(data.get(position).getUserInfo().getAvatar()).getPath());
Glide.with(context).load(imageURI).asBitmap().placeholder(R.drawable.placeholder)
         .error(R.drawable.error).into(holder.imV);

Answer 3

您还可以使用const filter = {} filter[Op.or] = [ { date: { [Op.gt]: sinceDate } }, { [Op.and]: { date: sinceDate, id: { [Op.gt]: sinceId } } } const result = await Posts.findAll({ where: filter })库。

UniversalImageLoader

OR

您可以在应用程序中使用Glide Library。你在任何适配器类中使用了load image，所以试试这个。

    universalImageLoader imageLoader =new universalImageLoader();

  imageLoader.loadImage(imageUri, targetSize, options, new SimpleImageLoadingListener() {
      @Override
      public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
        // use your bitmap …
      }
    });

Answer 4

试试这个：

 GlideApp
    .with(context)
    .load(url)
    .centerCrop() //cropping center image 
    .placeholder(R.drawable.loading_spinner) //placeholder while loading image 
    .into(viewHodler.myImageView);

Answer 5

试试这个：

Glide.with(context)
.load("your image url")
.into(holder.imV);

使用viewholder中的滑动从服务器加载图像
