How would one go about displaying an image in the Android Dialog that is retrieved from the internet from a URL? I have seen examples of Dialogs with pictures (like here: http://quickandroid.blogspot.com/2011/03/alert-dialog-with-list-of-text-and.html) but all that I saw is how the piture is retrieved from the drawable folder.
How to display the image in a dialog from a URL? Is dialog even the best choice? Should I download the image first?
Thank you :)
you can use universal image loader to download image from web
see the link bellow
https://github.com/nostra13/Android-Universal-Image-Loader
Universal Image Loader is a good tip. No need to download the picture yourself. You can first download the picture with UIL, then inflate a Dialog from a layout (needs only contain an ImageView) and show the dialog. Or you can extend DialogFragment, download the picture and show it from there.
If a dialog is the best way to show a picture is up to you and your app.

I want to do get drop box images and show into the listview. I also getting the Images from Dropbox. I have not understand how to do show it into list view.

Follow the next steps:
Make your Dropbox photos public, and create direct URLs, doing this: After you copy the public Dropbox link to your clipboard, just change ?dl=0 to ?raw=1 at the end of the URL.
Now, you just have to use picasso to retrieve the images with the code
Picasso.with(context).load("http://yourpubliclinktodropbox.yourimage?raw=1 ").into(imageView);
I recommend to you to host your images in another service in order to avoid that change on the dropbox image URL.
I hope it helps.

Follow this steps:
1.Outer activity which display folders:
Create an activity with grid view of custom item.Each item is framelayout with image and semi-transparent background textview.
2.Second activity which display images:
Create an activity with gridview of images.
To learn how to create gridview,use this
Scan folders that you want to include using a method like this
Generate a thumbnail by opening an image from the folder and resizing like so.
Place these thumbnails in a gridview, possibly with a small overlay stating the name of the folder.
When a user clicks into the folder simply generate thumbnails the same way as above but for every image.
Go through this code - CM Gallery
It's the official CyanogenMod gallery's source code. This will help you a lot in understanding how does gallery work.
Also go through this tutorial which I found really useful - Android Gallery
What I am trying to do is an app similar to iFunny or any funny picture apps. I want to be able to get a list of direct image links from the internet and then display the image one by one on a gallery. The user can swipe to see the next picture. What should I add to be able to do this. I never worked with a gallery before. Thank you.
You can set Uri directly to the ImageView of the Gallery. As follows...
Uri myUrl=Uri.parse(ImageUrlArray[Position]);
imageView.setImageURI(myUrl);
Do it in the getView method of the ImageAdapter you used.
I want to create a program that gets some images from a webpage, and shows them on a gridview. I dont know how many of them exactly. It could be from 20 to 30. Ill do it with asynctask, which i have allready used before and more or less know how it works. But i don't know which way use it this time.
For now, what i would like to get is a progressbar (circle clicking) while image is downloading. And once its downloaded, it would disappear and image will load. I will use an array of objects with an adapter, to fill the gridview.
Which way would you use the asynctask?
Thanks in advance.
I would suggest you check out Lecture 6 of Harvard Extension CS76. There is a URLImageAdapter and example source code that does example what you are looking for.
Best of luck
If you want to save downloaded images and reuse them in future then you must look DownloadManager
To display dialog with cycling circle, look this: howto use ProgressDialog
I have a Gallery and a few images stored in it.
On selecting the images i want some URL s to get opened on the top of this gallery(As a web view only).
For example If i click on a particular image i need a url to get opened.
I tried using ViewSwitcher and since I am a begginner i couldn move further.
Can someone tell if this is possible or suggest me the ways?
Check this link.
You basically need to use setOnItemClickListener and there add the code to lunch an url with an Intent.
