In my application I have a Gallery view and two buttons to scroll it - left and right. Scrolling the gallery by fling also works, and here is the problem: how can I update the states of buttons after the user scrolled the Gallery using fling movements? Is there any callback that tells that Gallery's selected item has changed? Thanks.
There is an onItemSelectedListener that you can use with a gallery. If you use it you'll probably also want to read about setCallbackDuringFling() that can enable/disable the listener while flinging.

I want to give animation in GridView. So that when the list gets prepared, it will scroll to given position without touching the screen.
You can use the methods smoothScrollToPosition and smoothScrollToPositionFromTop to make the GridView go to that position.
I got a listview with images and some info overlaying them. I want to make so, that when I tap an image info fades out from ALL OF THE LISTVIEW. then I can scroll images and tap on them for this info. how is it possible to do so?
Try to implement an onClickListener for the image view. When you tap on an image the listener will be called and you can change the view state of the info.
I used gallery view to display images but I want only one side to scroll. How do I stop left to right scrolling or backward scrolling? Or how do I create custom gallery?
GallerView is a deprecated widget.
I use ViewPager which you can modify as a custom gallery. Your fragments will be your slides or images which you will be able to swipe around.
You can read more about that here or here.
If you want to swipe only one way, then you would have to extend ViewPager and override onTouch event.
I am using a gallery in my app. I am using the code given here. The problem is while clicking a item in gallery it moves to the left (as default gallery property is to move the item selected to the center).How to stop the item to scroll to the left.
You need to adjust the Horizontal Scroll of the Gallery element.
gallery.scrollTo(yourOffset,0);
I'm try to implement disable Gallery scrolling when pictures in gallery is less than 5 pictures.If I have more than 6 pics the scrolling will enable scrolling in Gallery!
but I have no idea how to implement it. I have already reference "Gallery default item selected is in center", to adjust first picture to the left,
after adjust the first picture, I reference "how to stop scrolling gallery?" , but it doesn't work! and "Android Custom gallery to disable scrolling.." don't have any solution..
Any one have idea? how to disable scrolling the picture in Gallery?
Here I am giving you one solution whatever I am getting from your question In place of gallery You can make view like gallery by using Horizontal scroll view, add linearLayout in that and add image view dynamically if images is coming dynamically to linearLayout so it will resolved scrolling issue and left align problem as well.
