问题

我正在尝试使用Glide加载个人资料图片，但在运行时抛出了空URL的错误。以下是代码部分：

BindingAdapters.java

public final class BindingAdapters {

    @BindingAdapter({"app:profile_url"})
    public static void loadProfileImage(ImageView view, String profileUrl) {
        new GlideLoader(view.getContext()).loadWithCircleCrop("http://aplikasi.muanetoraya.com/jaih/uploads/" + profileUrl, view);
    }

    @BindingAdapter({"app:image_url"})
    public static void loadImage(ImageView view, String profileUrl) {
        String url = "http://aplikasi.muanetoraya.com/jaih/uploads/" + profileUrl;
        new GlideLoader(view.getContext()).loadImage(url, view);
    }
}

这段代码在运行时抛出以下错误：

W/Glide: 加载失败，大小为 [240x240]，URL：http://aplikasi.muanetoraya.com/jaih/uploads/null
    class com.bumptech.glide.load.engine.GlideException: 无法加载资源

Here is my code:

    BindingAdapters.java

    public final class BindingAdapters {
    
        @BindingAdapter({"app:profile_url"})
        public static void loadProfileImage(ImageView view, String profileUrl) {
            new GlideLoader(view.getContext()).loadWithCircleCrop("http://aplikasi.muanetoraya.com/jaih/uploads/" + profileUrl, view);
        }
    
        @BindingAdapter({"app:image_url"})
        public static void loadImage(ImageView view, String profileUrl) {
            String url = "http://aplikasi.muanetoraya.com/jaih/uploads/" + profileUrl;
            new GlideLoader(view.getContext()).loadImage(url, view);
        }

and it throw error like this:

**得分**: 2

java.io.FileNotFoundException(http://aplikasi.muanetoraya.com/jaih/uploads/null)
表示您的
profileUrl
为空，因此此链接http://aplikasi.muanetoraya.com/jaih/uploads/null中的资源可能不可用。
