Question

在我的应用中，我的captureBonus活动（ImageView所在的地方）中也包含以下代码：

// Process the Sample Image
bonusSampleImage = findViewById(R.id.bonusSampleImage);
Glide.with(this)
    .load("http://i.imgur.com/DvpvklR.png")
    //.load("https://www.tourofhonor.com/appimages/2019fl4.jpg")
    .into(bonusSampleImage);

但是，当我运行我的应用程序时，我根本看不到任何图像视图。在添加上面的代码之前，将出现带有占位符的图像视图。另外，我尝试了代码中的两个链接，但均无效（我认为这与https有关）。

我已经具有Internet和外部存储权限。

我发现Glide在logcat中记录了一些活动，尽管如此，它只能在详细模式下查看：

2019-05-01 16:51:38.329 3182-3182/net.tommyc.android.tourofhonor W/Glide: Failed to find GeneratedAppGlideModule. You should include an annotationProcessor compile dependency on com.github.bumptech.glide:compiler in your application and a @GlideModule annotated AppGlideModule implementation or LibraryGlideModules will be silently ignored

If you want to load the original image and are ok with the corresponding memory cost and OOMs (depending on the input size), use .override(Target.SIZE_ORIGINAL). Otherwise, use LayoutParams.MATCH_PARENT, set layout_width and layout_height to fixed dimension, or use .override() with fixed dimensions.

Answer 1

您在URL中缺少s。请使用https代替http作为图像URL。

Glide.with(this)
    .load("https://i.imgur.com/DvpvklR.png")  // Add https instead of http
    .placeholder(R.drawable.sample_image_missing)  // Add a placeholder here
    .into(bonusSampleImage);

以下内容与您的build.gradle文件中的依存关系有关。我认为这是失踪的。

annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'

如Glide's文档中所述，如果您还没有存储库，则也需要它们。

是的，请检查您的互联网连接。

Answer 2

dependencies {
  implementation 'com.github.bumptech.glide:glide:4.9.0'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
}

repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
        maven { url 'https://maven.google.com' }
    }

创建一个MyGlideApp类并重建您的项目。

@GlideModule
public class MyGlideApp extends AppGlideModule {

    @Override
    public boolean isManifestParsingEnabled() {
        return false;
    }
}

将此内容粘贴到您的活动课程中

public void loadGlideImage(Context context, ImageView imageView, String url) {
            GlideApp.with(context.getApplicationContext())
                    .load(url)
                    .signature(new ObjectKey(url))
                    .dontAnimate()
                    .into(imageView);
    }

那你就可以做

String img_url = "https://www.tourofhonor.com/appimages/2019fl4.jpg";
loadGlideImage(this, bonusSampleImage, img_url);

滑行未在我的android应用中显示图像
