I'm trying to download image from url using Asynchronous downloading method that I find in Stack overflow.We can see the image is downloading from the console prints , but the image is not getting displayed in image view.
The problem is that https://imgur.com/2yO5RbG is not an image; it is an html page, as your own test tells you right in the console. So the call to UIImage(data:) fails and returns nil. The image is at https://i.imgur.com/2yO5RbG.jpg.

I want to get the url of img from website with flutter. But when I use .attributes［'src'］for getting the image url, I get the loading svg. is there any way to get the image url not the loading svg??
I want to add an image that I added to my application from the phone's gallery to the list and call it with Image.asset as a String value.
I managed to get the image with ImagePicker. Unfortunately, there is no next. I don't know exactly how to do this.
In short: I will select an image from gallery with ImagePicker and replace it with "Image.file"
I will do it by converting it to String value with Image.asset.
You have to use image.file or image.memory to load an image from ImagePicker.
image.asset is for images that already exist within your app.
I am using 'SwiftSoup' SDK to parse HTML content from UIWebView. I want the image size and resolution for each and every image fetched from HTML content. How to get the image size and resolution as soon as an image is loaded and from HTML content received from SwiftSoup?
Assuming you know when all images from the HTML are loaded, here's a javascript code that can be used to grab a list of sizes for all images:
let script = "JSON.stringify([].slice.call(document.getElementsByTagName('img')).map(function(img) { return {url: img.src, width: img.clientWidth, height: img.clientHeight} }))"
Executing this javascript via stringByEvaluatingJavaScript(from:) should give you a JSON that you can parse to obtain the desired info.
For example the output for this page is
[{"url":"https://i.stack.imgur.com/rQQMq.png?s=48&g=1","width":24,"height":24},{"url":"https://www.gravatar.com/avatar/46be6ae9d14855f5ab1aaf1d510ab8bc?s=32&d=identicon&r=PG&f=1","width":32,"height":32},{"url":"https://clc.stackoverflow.com/impression.gif?an=49ocs77evOWqh-6LVv8gJiaWI_07xL9f6GBcyDt7dl3NWtNsxo9-twOOBzKwMPRsYGBosGdkZGCRZuqawDHjMeecj4L_WRhSDiyObbJ82JRhP5vp7j6Og2e4ru0W9mRhmNs0gbnc8pVcsT0jc2Z-sTTTwxaOliucyy4LsrAwFLRcfRVt-e6KDEjTco4LjVyda4XkgZqaJcJzLa9Oj4RoMrJk4eJgYpBgYGDg4o1ij5VnYhAHsvk4o9gSmZgYRIBsfmYbtrvCTAxiIHH2ALapwv3t9i1z_NRrAA&md=291","width":0,"height":0}]
I'd recommend though to switch to WKWebView since it's recommended also by Apple, and because stringByEvaluatingJavaScript(from:) is blocking (WKWebView provides an async version of this function, and one that also will do the parsing for you, so you can remove the JSON.stringify() call from the script).
I want to load image in card view with other data like title and desc.
I am uaing php to get result as json response which is working and also i am able to set data to textview and pass from one activity to other !
Only problem i am facing is in setting image in image view.
i can add image manually by making listview obj and storing link in ArrayList obj
Like obj.add(R.drawable.feature1.jpg)
How to do it dynamically from the json response i am getting ?
Sorry if i sound confusing as i am new to android and just want to make a image gallery where first i will display list of albums and after clicking one of albums all images from that albums are loaded and displayed.
{"products":[{"mid":"1","title":"Demo Video 1","link":"https:\/\/m.youtube.com\/watch?v=PCwjNfSM-U","mediaCreatedOn":"2015-08-30 18:59:18","mediaUpdatedOn":"0000-00-00 00:00:00"},{"mid":"2","title":"Demo Video 1","link":"https:\/\/www.youtube.com\/","mediaCreatedOn":"2015-08-30 18:59:18","mediaUpdatedOn":"0000-00-00 00:00:00"}],"success":1}
The above is the output from server side where only the youtube link is replaced by server img location.
Thank you for reading, have a nice day ahead :)
1:You can store image to database Example:mysite.com/img/34324234342.png (phpMysql)
2:And you can get image from php rest service (Only image link)
3:For load image from link , you can use picasso library (android)
4:If you want image with text, you can use custom listview
Example xml for restful service.
<myimage>
<title>abc</title>
<ipath>mysite.com/img/34324234342.png</ipath>
</myimage>
I created this custom annotationView that can contain a logo and a label in the screenshot the logo is stored locally,
screenshot : http://hpics.li/3c45def
now I want to display the logo stored on the server, I tried to integrate the tableview imagedownloader but I failed, someone has an idea of where to start
Thank you
You can use NSURLRequest to download the raw data for the image from the server. Once downloaded you can set the image in your tableview.
You start by having a look at this post.
