How to load image without file extension from URL to ImageView in Android

由 自闭症网瘾萝莉.ら 提交于 2019-12-24 20:07:48
问题 I have this URL https://speakyfox-api-qa.herokuapp.com/api/v1/files/be28dcec-4912-4f58-8cb8-12b9b2948fc3 . There is a PNG image on this URL address in blob storage accessible without any headers (normally) on the REST API. It opens normally from the web browser (e.g. Chrome). However, any attempt to load it in Java Android application to ImageView fails miserably. I have tried Volley, Picasso, Glide, Retrofit and manual methods. I include some code I have tried. The closest I have got to it

Volley - NetworkImageView sometimes doesn't show the error image?

问题 So I've decided to try out the new Volley library as shown on Google IO 2013. I've tried it out while using the easy solution of NetworkImageView to show multiple images on a GridView . It works nice and shows images, but if I let it download the images and then I turn off the WiFi during the download, it doesn't show an error as if everything still loads. Not only that, but if I restore the connection, it doesn't resume the loading. Why does it occur, and how can I fix it? Maybe it's

问题 I am new to work on Volley and on caching too :P. Though I have already gone through a number of articles & posts related to Image Caching with Volley but I am still not clear with the best/preferred way for Image Caching with Volley. Like disk caching or memory? What support does Volley already provide and how (related to L1 and L2 caching support)? I am using NetworkImageView in my case, to populate a list view with images to be fetched from net. Thanks in advance! 回答1: For image caching,

问题 in my android app, I am listing the images' previews with network image view. I want that if user press the previews it opens an activity with viewpager and show the original images of specific item of my recycler view. So, i have a two method in my mind. 1-) I will save two image for each of my images in my database. One of them will be preview image with small size and other one will be the original one. In my main newsfeed, app will load the preview images so download size will be smaller.

由 江枫思渺然 提交于 2019-12-11 06:07:51
问题 I am using RecyclerView and volley's NetworkImageView to render images once they are downloaded. The view consists of an author image, some text fields and a picture. Following is the code snippet to populate the view: // vh is the viewholder vh.picture.setDefaultImageResId(R.drawable.default_image); vh.picture.setImageUrl(post.getImageUrl(), mImageLoader); The problem I am facing is when scrolling, out of say 20 images, mostly ~18 show up. I see from the logs that all images are downloaded

display NetworkImageView's default image without network request

由 时光总嘲笑我的痴心妄想 提交于 2019-12-08 15:01:00
问题 I have a ListView displaying things, many of which have an illustrative image and some of which don't. The ViewHolder uses NetworkImageView to display the illustrations. The problem is that even if a default image is set, it won't be displayed until one calls setImageUrl(), which in turn will set the source bitmap of the view to null if the url is empty. If the url isn't empty, it makes a request. This means that one is forced to make a network request even if there isn't a valid network url

Adding Authentication Headers to NetworkImageView in Volley

由 ≡放荡痞女 提交于 2019-12-04 04:34:55
I use Volley and NetworkImageView. This has been working great for several projects. However I need to send auth token in headers for my image request right now. What is the best way to do this? In my normal requests I override getHeaders() and put my token in that way. But ImageLoader which is what NetworkImageView uses generates a generic Request, making it hard to add headers... I have come up with a solution. In order to use NetworkImageView you need to create an image loader. At this point of the code, just overide the makeImageRequest() method of ImageLoader , and inside makeImageRequest
