Question

我正在尝试使用滑动将图像从URL加载到我的imageview中，但它无法正常工作。我无法下载和显示图像。我已经在我的项目中添加了所有依赖项和权限，但它似乎仍无法正常工作。任何想法哪里出错了？以下是我项目中的所有文件。奇怪的是我的日志中没有出现任何错误或异常

Answer 3

我找到了这个答案here，并且有人也在stackoverflow上发布了此答案。我尝试使用上述代码几个小时，但出现错误。我无法解释，但对我有用

第一步：将其发布到 build.gradle

 implementation ("com.github.bumptech.glide:glide:4.9.0") {
    exclude group: "com.android.support"
}
// Glide v4 uses this new annotation processor -- see https://bumptech.github.io/glide/doc/generatedapi.html
annotationProcessor 'androidx.annotation:annotation:1.0.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
implementation ("com.github.bumptech.glide:glide:4.9.0@aar") {
    transitive = true
}

第二步：创建一个空的公共类，并扩展AppGlideMoudle并包含

 import com.bumptech.glide.annotation.GlideModule; 
 import com.bumptech.glide.module.AppGlideModule;
 public class MyAppGlideModule extends AppGlideModule {
 // empty class
 }

最后一步：添加到MainActivity

 String urlimage= "url for the image";
        posterImageView = findViewById(R.id.imagePoster);
        Glide.with(getApplicationContext())
                .load(urlimage)
                .into(posterImageView);

在Android中使用Glide加载图片
