Question

我正在尝试从url异步加载图片（在后台线程上）。

尝试这样的事情：

  val futureTarget = glide
    .asBitmap()
    .load("https://dummyimage.com/300/09f/fff.png")
    .submit(300, 300)

  val bitmap = futureTarget.get()

但是，当尝试从URL加载任何图像时，它会使应用程序崩溃，并且在加载本地资源时可以正常工作。

Logcat

There was 1 cause:
    com.bumptech.glide.load.HttpException(Not Found)
     call GlideException#logRootCauses(String) for more detail

    There was 1 cause:

     call GlideException#logRootCauses(String) for more detail

我添加了Internet权限。

<uses-permission android:name="android.permission.INTERNET" />

使用Dagger 2提供Glide

@Provides
@Singleton
static RequestManager provideGlide(final Application application) {
    return GlideApp.with(application);
}

知道我缺少什么吗？

更新

我发现某些HttpInterceptor存在问题。该解决方案可以同步下载位图。

Answer 1

尝试一下。

    val options = RequestOptions()
            .placeholder(R.drawable.your_placeholder_image)
            .error(R.drawable.your_error_image)

    Glide.with(this).load(image_url).apply(options).into(imageView)

编辑：-获取Callbacks

Glide.with(this)
        .load(url)
        .listener(object : RequestListener<Drawable> {
            override fun onLoadFailed(e: GlideException?, model: Any?, target: Target<Drawable>?, isFirstResource: Boolean): Boolean {
                //TODO: something on exception
            }
            override fun onResourceReady(resource: Drawable?, model: Any?, target: Target<Drawable>?, dataSource: DataSource?, isFirstResource: Boolean): Boolean {
                Log.d(TAG, "OnResourceReady")
                //do something when picture already loaded
                return false
            }
        })
        .into(imgView)

尝试一下...。这将为您提供帮助。

Glide.with(this)
  .load(image_url)
