I have an app and it's main layout has an imageview and a textview. I want the imageview to load whatever image is the thumbnail from the website and the text to load the title of the post on the website. Layout looks like this. Thanks in advance.
I have scoured the internet to no avail, any help is appreciated.
There's nothing 'ready-made' available.
You'll have to:
Find what's the website API (or create one);
make a call to this API to acquire the site data (usually as JSON or XML);
parse that data into meaningful information;
download the image (usually as a Bitmap object);
and set this Bitmap to the ImageView using the method .setImageBitmap(Bitmap);

I have a list of photos that I want to display so I am using a RecyclerView and a RecyclerView.Adapter. So when I bind the view in onBindViewHolder(), I do something like this:
// photo is a Object that contains a url
// photoViewHolder.photo is the imageview
Glide.with(photoViewHolder.photo.getContext()) //use the imageview context
.load(photo.getPhotoScaledURL())//load the photo using an url
.into(photoViewHolder.photo); //into the imageview
But here I am always relying on the URL. Would I be able to somehow always have this image cached? Or is there a better way to do this?
To show some of the images offline first download your image and store the path in DB.Now whenever you offline show the downloaded image.And when online just check the whether image is already downloaded or not, If downloaded then show downloaded image else use glide.
I am currently doing a project which needs to load images in a listView with some text from web.I am using universal image loader library,every thing work fine images are loading perfectly without any problem, but my requirement is that if there is no image in a specfic url, i dont want to show that image view in the listview row.which is similer to the news stand app of google.
in the above screen of the newsstand app if there is no image the imageview is not shown and the text will fill to the total width of the cell or row in the listview.How can i achieve this requirement.i have goggled but did not get any right solution or clue to fix this issue,can any one give any snippet or any idea to sort out this issue.
Thank you
In your adapter, when you call the library to display the image, if there is no image url just set the visibility of your ImageView to GONE (and VISIBLE again when there is an url).
If you want to wait that the image is completely loaded to make the ImageView visible, you'll need to register a loading listener. See here.
I am working on a simple app and I am having issues understanding how to use volley for something I feel should be an easy task. Currently I have gotten volley to grab a json array that populates a list of images with titles next to them. The problem is I want to be able to press on an item in the list and spawn a new fragment with a larger version of the image in it. This seems like a really basic task, but I can't seem to find the right way to do it. If I grab the full images to create the list view, I run out of memory. I started grabbing thumbnail images, but then when I create the fragment, the view is inflated before the request for the image finishes. What is the right way to do this?
You can specify a placeholder image while Volley downloads your image, and an error image if the download wasn’t successful. In your situation, you can use your thumbnail image as the placeholder image.
The Making Image Request section in this artcle shows the good way to handle image request with Volley.
Sample code:
// Loading image with placeholder and error image
imageLoader.get(Const.URL_IMAGE, ImageLoader.getImageListener(
imageView, YOUR_THUNMBNAIL_IMAGE, R.drawable.ico_error));
I was thinking of an app that would pars images and text from a rss and that the output will be like this:

but my question is how i could get the image from rss in a imageview with fill_parent as width and that there would be an textview on the imageview.
Does anybody know how to do this?
Taken from this post
See this custom or dynamic Listview example
also see this to how to load image from URL
This is the most comprehensive RSS reader tutroial I've found as well.
I'm trying to display several Images dynamically. After retrieving a url from xml parsing, I convert it to a Bitmap and loaded in image view using setImageBitmap in AsyncTask ,but current url image does not loaded but next url images loaded,whenever call next url,so i want to refresh or reload imageview in AsyncTask?.is it possible? possible please give code for me..
Thanks all
You can use Droid-fu's WebImageView.
