从 Firebase 存储中获取图像

Question

我是整个 Firebase 存储概念的新手。

我做了一些研究，发现了这个滑翔机。用于将图像添加到 imageView。现在它给了我这个错误。

我该如何解决？

还有其他方法吗？

这里是代码

StorageReference mStorageRef = FirebaseStorage.getInstance().getReference();
final StorageReference imgRef = mStorageRef.child("images/img.jpg");
final long ONE_MEGABYTE = 1024*1024;


imgRef.getBytes(ONE_MEGABYTE).addOnSuccessListener(new OnSuccessListener<byte[]>() {
    @Override
    public void onSuccess(byte[] bytes) {
        Glide.with(Cari.this).load(imgRef).diskCacheStrategy(DiskCacheStrategy.ALL).into(kuryerImg);
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {

    }
});

Answer 1

使用FirebaseImageLoader

Glide.with(this /* context */)
    .using(new FirebaseImageLoader())
    .load(storageReference)
    .into(imageView);

Answer 2

我有其他方法可以解决问题。

您可以获得图片的下载网址。 这是来自 Google 指南的代码。

StorageReference storageRef = 
  FirebaseStorage.getInstance().getReference();    
 storageRef.child("users/me/profile.png").getDownloadUrl()
.addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
    // Got the download URL for 'users/me/profile.png'
    })
.addOnFailureListener(new OnFailureListener() {
  @Override
  public void onFailure(@NonNull Exception exception) {
    // Handle any errors
   }
});

如果您需要将图像下载到设备的指南，这里有一个 Stackoverflow 链接： Download Image from URL

使用通用加载器而不是使用滑动，它加载图像比滑动更快

   DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
        .cacheOnDisc(true).cacheInMemory(true)
        .imageScaleType(ImageScaleType.EXACTLY)
        .displayer(new FadeInBitmapDisplayer(300)).build();

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(
        getApplicationContext())
        .defaultDisplayImageOptions(defaultOptions)
        .memoryCache(new WeakMemoryCache())
        .discCacheSize(100 * 1024 * 1024).build();

ImageLoader.getInstance().init(config);

final ImageLoader imageLoader = ImageLoader.getInstance();

final DisplayImageOptions options = new DisplayImageOptions.Builder().cacheInMemory(true)
        .cacheOnDisc(true).resetViewBeforeLoading(true)
        .showImageForEmptyUri(R.mipmap.preview)
        .showImageOnFail(R.mipmap.preview)
        .build();


 mdatabase.child(Table_item).addValueEventListener(new ValueEventListener() {


    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        Map map = (Map) dataSnapshot.getValue();
        String image1 = (String) map.get("imagename");
        String image2 = (String) map.get("image2name");
        imageLoader.displayImage(ImageView1, image1, options, new ImageLoadingListener() {

            @Override
            public void onLoadingStarted(String imageUri, View view) {

            }

            @Override
            public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
                progressBar.setVisibility(View.GONE);
            }

            @Override
            public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {


            }

            @Override
            public void onLoadingCancelled(String imageUri, View view) {
                progressBar.setVisibility(View.GONE);
            }
        });
        imageLoader.displayImage(ImageView2, image2name, options, new ImageLoadingListener() {
            @Override
            public void onLoadingStarted(String imageUri, View view) {

            }

            @Override
            public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
                progressBar.setVisibility(View.GONE);
            }

            @Override
            public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
                i++;
                progressstatus(i);
            }

            @Override
            public void onLoadingCancelled(String imageUri, View view) {
                progressBar.setVisibility(View.GONE);

            }
        });

使用以下依赖：

compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
