I want to display thumbnail image as image icon in ListView.
I am using array list that contains all thumbnail images path, these path will be accessed from the server.
My arraylist as ahown below.
mylist=['a1','a2','/playback/2012/a1.jpg','b1','b2','/playback/2012/000_b1.jpg', .....]
In this nearly 15 paths are there.. Now i want to display these images in listview.
'a1' is videoName 'a2' is categoryName and one more is path.
These path will be accessed from server only.. I think, we can't store it in drawable.
These are always changing.
How to solve it?
Please help me.

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 new to android, please help me to resolve this. I need to retrieve all images from gallery and show that like an animation using timer or thread. I Used below code get images from gallery how can I store the images in an array?My idea is to make animation using timer by picking images from an array and put in a single Imageview. but I could not store the images retrieved from gallery to an array. I could display it in gridview by using Imageadapter. In short I need to get n number of images from gallery and place it in an array and make animation using timer and single imageview.
String[] projection = {MediaStore.Images.Thumbnails._ID};
cursor=getContentResolver().query(MediaStore.Images.Thumbnails.INTERNAL_CONTENT_URI,
projection,null,null,MediaStore.Images.Thumbnails.IMAGE_ID);
You need to use AnimationDrawable and it's addFrame method. Here is the document.
You can try below link.
It will show how you can select multiple images from gallery;

I need a tutorial where in I can get images from a folder to display in grid view and then on click of the image in grid I can see full view and swipe functionality
any tutorial or code here please
thanks in advance
I think this is not hard to perform.
Find out your SD card folder path, scan and store image files and get image path in the SD card folder, get the bitmap from stored image path and put in to gridview. set gridview item selected listener to display image when click on a item.
There will not have a example code contains all the function you need. you can divide the problem to small ones, then try to solve it piece by piece. For example: solve scan image file from a folder first.
If the code given in gitHub can not fetch your images then paste the
path here which is used to fetch the images.
To set images in grid view, you already got the code. But now you
want to slide the images one by one. Then I can give you a hint that
use gallery view of android. It provides slider of small images. You
need to change the resolution of images. You need to combine these 2
views.
I don't know how to get the images what are available on the scree. I'm using imageview for the purpose of display the images on the screen.
Images will be changed randomly because i stored the images into array and images are in drawable. I want to know which image is displays on the screen at runtime.
thank u
When you change the image in the ImageView, hold onto the array index that you used in another variable.
I have a ListActivity that should display quite a lot of items and where each list item should contain a text and and an image. The images are gotten from a remote server. How can I display the remote image on the list item. Thanks in advance
Download the images into memory or a local cache using HttpURLConnection or similar then use BitmapFactory.decodeByteArray to convert the downloaded images into bitmaps and assign them to ImageViews using setImageDrawable to display them.
