I add many ImageView to HorizontalScrollView, each ImageView load image from internet. But screen only display 3 ImageView.
I want to know what ImageView is on screen because I want to remove image from another ImageView that not display in screen.
Is there anyway to do that ?
Sorry for my bad English.
You need to consider using lazy ListView instead of <ScrollView> for your images. With a lazy ListView, the app won't download the hidden images until the user scroll to view them.
I'm not familiar with such a ListView but I think those links might help you:

How to possible for Drag and Drop image from one GridView to another GridView?
I am using only ImageView for one GridView.
TextView and ImageView using for second Gridview.
My screenshot is:
Image set using Piccaso (use Image path). Not download image from server, directly set path using Picasso and display image in GridView Item.
How to do it?
Please suggest a solution.
Thanks.
You could use DynamicGridview. Take a look at this tutorial.
I have an app that loads content from a database as well as images from the internet. I am using a RecyclerView along with CardView to display my content in a list form.
Each row has an image on the left side and text on the right.
The problem is that the text loads fast but the image takes time to load, so I want the image to continue loading in the background and then load into the ImageView object once loading is complete. I have no idea how to tackle this.
I use Picasso for this situation, but u can also use Glide and many more libraries. The documentation is pretty simple.
Try Picasso:http://square.github.io/picasso/
It's a one liner in onBindViewholder():
Picasso.with(context).load(url).into(viewHolder.imageView);
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 have a listView in which I have text and an image view Now the data is coming from the service in this case text is of some bytes but due to images size imageview populate after some time . for this I want to show loading symbol in in imageview so that in time of downloading user not say that the app is not able to show images. I have implemented all listActivity and adapters concepts and its working fine but the images take time due to which the imageview part shows black area . any help
Here this I want:
In Android we called it lazy list..
this will help you to understood..
1.Lazy loading of images in ListView
2.http://www.technotalkative.com/android-asynchronous-image-loading-in-listview/
For Image issue :
Change in ImageLoader class (if Using Lazy List)
final int stub_id=R.drawable.ic_launcher; //change it to process image
Good Luck
Place a ProgressBar and keep the imageView over the ProgressBar.So the progress bar is visible when there is no image in the image view. Also use lazyList to load image.
You might want to check out Android Query. it's a library that also supports Asynchronous image loading and caching.

In my apps i want to display images and text in three ways
ListView
GridView
FullScreen
i have 500+ images and text that i parse using JSON and store into SQLite.
I know how to create ListView & GridView but problem is I don't know how to create the custom layout.
I have image but due to my low reputation i am not able to post image.
I try to explain what i need.
I need custom fullscreen layout that has 2 buttons, one on the left and other on the right and between those 2 buttons I need Imageview that display the fullscreen image.
thanks in advance
Use UniversalImageLoader library, as it has all the modes you need. It also supports caching and lazy load, which you will definitely need on 500 images.
