I am using GridView to display more than 100 images from web. Its takes time to load and display, so I use lazy loading but that does not speed it up.
So I want to display the view or activity first and then I want to display the images in the background.
How do I achieve this?
Thank you
Have you tried Fedor's Lazy Loading logic: Lazy load of images in ListView
Yes this answer is for Loading images inside the ListView, but you can use the same for GridView as well. I had implemented previously and it was working fine in my case.

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'm developing an Android app that is used to get Images and texts from the internet using JSON.
I want to display these images and texts in gridview using a lazy loading approach to avoid the out of memory exception.
Say that i need to display 100 items, I want to display only 20 items after opening the activity and when i scroll down, another 20 items will be loaded, and so on.
How can i achieve that?

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.

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:
Question: How to do a lazy load of images in ListView?
A solution implemented
Project: Android Universal Image Loader
I have a listview that loads images form urls
I get lag when when images are out of view. Meaning the ones That i have to scroll to see, seems to be loading from the internet while I am trying to scroll to them.
How can I let the listview load all my images at first run?
I know this is an old question, but for those who have a similar problem:
The Glide Library could help with it. I had this problem as well and I could solve it by using Glide. You can load an image like this:
Glide.with(mContext)
.asDrawable()
.load(mImageUrl)
.into(mViewHolder.mImageView);
