使用firebase cloud时未加载图像[重复]

Question

因此，我正在开发一个小型聊天应用程序，可以加载存储在Firebase Cloud中的图像。

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_SIGN_IN) {
        // Code for text message
    }
        else if(requestCode==RC_PHOTO_PICKER && resultCode==RESULT_OK){
            Uri selectedImageUri=data.getData();
            StorageReference photoRef=mChatPhotoReference.child(selectedImageUri.getLastPathSegment());
            photoRef.putFile(selectedImageUri).addOnSuccessListener(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    String downloadUrl=taskSnapshot.getMetadata().getReference().getDownloadUrl().toString();
                    FriendlyMessage friendlyMessage=new FriendlyMessage(null,mUsername,downloadUrl);
                    mDatabaseReference.push().setValue(friendlyMessage);
                    Log.e("WWWWWWWWWWWWWWWWWWWWWWW",downloadUrl);

                }
            });
    }

}

public View getView(int position, View convertView, ViewGroup parent) {
    if (convertView == null) {
        convertView = ((Activity) getContext()).getLayoutInflater().inflate(R.layout.item_message, parent, false);
    }

    ImageView photoImageView = (ImageView) convertView.findViewById(R.id.photoImageView);
    TextView messageTextView = (TextView) convertView.findViewById(R.id.messageTextView);
    TextView authorTextView = (TextView) convertView.findViewById(R.id.nameTextView);

    FriendlyMessage message = getItem(position); 

    boolean isPhoto = message.getPhotoUrl() != null;
    if (isPhoto) {
        Log.e("VVVVVVVVVVVVVVVVVVVV",message.getPhotoUrl());
        messageTextView.setVisibility(View.GONE);
        photoImageView.setVisibility(View.VISIBLE);
        Glide.with(photoImageView.getContext())
                .load(message.getPhotoUrl())
                .into(photoImageView);
    } else {
          Load text..
    }
    authorTextView.setText(message.getName());

    return convertView;
}

Answer 1

尝试使用RequestOptions应该如下所示

RequestOptions options = new RequestOptions()
                    .centerCrop()
                    .placeholder(R.mipmap.ic_launcher_round)
                    .error(R.mipmap.ic_launcher_round);



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

如果您没有获得url，您将显示错误图像，在本例中为ic_lanucher_round
