I want to make a Gallery View with slide show and image zooming(as the default gallery in android). I started with implementing ViewFlipper. I have added ImageView to ViewFlipper in runtime. But it takes very long time to load large number of images initially. And i couldn't make image zooming. Can anyone provide good solution take make an efficient gallery view with slideshow and image zooming??

I'm trying to replicate the functionality of Facebook's image upload. To briefly describe it you click the Photo button from the main screen of the app you are taken to an image picker that will let you select up to 30 images. Once selected the images load in some kind of list view that allows you to add a caption, remove the image from the list, or do some other Facebook-y things. If you scroll around the list can move very quickly, and if you only have 5-10 images you generally spend little to no time waiting for items to reload.
Right now I have a recycler view and am using Picasso to load the images from disk, resize them, and then display them. This works, but it's not smooth or fast. Even if I only have five or six images loaded they don't come up instantly if I scroll from the bottom back to the top. I have tried increasing the LRU Cache size in Picasso, but that didn't do anything at all. It seems like the scaled image isn't getting cached so it has to be scaled to fit the screen width every time. That's just my guess though.
Any suggestions on how to get this to run more smoothly?
I am getting url of 10 images from server and I want it to display in a image view which flips the images automatically and also we can flip. I am not sure what to use whether image gallery or view flipper or some animation.
I am using an Image Loaded which loads images based on requirment and since the images are big. I want to display an intermediate Spinning Image showing which would convey that the image is loading to the User.
I am displaying these images in the Viewpager.
We can not use a Gif image to display the animation and i wonder how it can be done.
P.S i am not looking for a Progress Dialog.
You could try doing a View Animation on the ImageView. Rotate is one of the included animations, and you can define it in XML.
Here's a Youtube Video from Google explaining it a little more.
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:

I have a gallery that I use to display some ImageViews. I'd like to know which image in the gallery is currently highlighted/focused.
So far, setOnItemClickListener only fires if I actually click on the images. If I scroll through the images, a new image takes focus. I want to know which image that is.
How can I do this?
Get the images number in the list
Get the image (view) it self
