Question

我希望使用 json 从服务器加载图片并使用 //model public function logo(){ return $this->belongsTo(Media::class, 'image_id'); } //template echo $product->logo()->count(); 库将其显示到ImageView，我写下面的代码但没有显示给我Glide中的任何图片!!
对于此问题，我使用imageView和Log.d用于显示图片链接（服务器上的图片链接）并显示图片链接，但在toast中没有任何图片!!

DataModel：

imageView

AsyncTask：

public class DataModel implements Serializable {

    private static final long serialVersionUID = 1L;
    private int id;
    private String title;
    private String description;
    private String image;
    private String category;
    private String date;
    private String price;

    public DataModel(int id, String title, String description, String category, String date, String image) {
        this.id = id;
        this.title = title;
        this.description = description;
        this.category = category;
        this.date = date;
        this.image = image;
    }

    public String getPrice() {
        return price;
    }

    public void setPrice(String price) {
        this.price = price;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getCategory() {
        return category;
    }

    public void setCategory(String category) {
        this.category = category;
    }

    public String getImage() {
        return image;
    }

    public void setImage(String image) {
        this.image = image;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

}

适配器：

    private Context mContext;
    private String ServerAddress = freeServer_IP.getFreeIP();

    public void getFreeDataInfo(Context context) {
        mContext = context;
        new getInfo().execute(ServerAddress + "limit=10");

            dialog = new ProgressDialog(mContext);
            this.dialog.setMessage("شکیبا باشید...");
            this.dialog.show();

            infoModels.clear();
        }

                    .cacheControl(CacheControl.FORCE_NETWORK)
                    .build();

                            Log.d("Data", "---------------------------------");

                            //Use the title and id as per your requirement
                            infoModels.add(new DataModel(id, title, description, category, date, image));
                        }

如何解决此问题并在06-11 05:37:20.808 1692-1692/com.razemovafaghiat.tellfa.android D/ImageData: image : http:/razemovafaghiat.ir/uploads/download/egve.jpg中显示图片？谢谢所有＆lt; 3

Answer 1

您遵循了正确的方法。但问题非常棘手，但易于解决。

您收到的网址是

http:/razemovafaghiat.ir/uploads/download/egve.jpg

但应该是这个，

http://razemovafaghiat.ir/uploads/download/egve.jpg

Glide 无法理解或解析以前的网址。我尝试过，它与第二个网址完美配合。

只需将您从服务器收到的网址更改为正确的网址格式即可。如果您无法控制后端服务器，请尝试更正客户端代码中的URL。

如果您希望看到此工作一次，请尝试一次，

Glide.with(getContext()).load("http://razemovafaghiat.ir/uploads/download/egve.jpg").into(mImageView);
