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 view pager in a recycler view cell, which is swiped to reveal a checkmark image. Outside of this, the recycler view is contained in a fragment which is located inside of another viewpager. What I want to accomplish is, after the cell's viewpager finishes, it begins to drag the view pager containing the fragment. I have been working on this for two days and have not reached any solution. It works fine if I lift my finger between swiping the view pager in the cell and then swiping the screen again to swipe the fragment's view pager. However, I want this swipe to be possible without having to lift a finger off the screen. A good model of this is snapchat's swipe to message views. Any help would seriously be appreciated. i do not know what to do. I can provide code, but it's fairly complicated and messy.
The images below are the current app I am trying to execute this behavior in. They are for testing purposes of course. Image 1) is before nothing is swiped. Image 2) is after the cell's view pager has been swiped, and Image 3) is after the fragment's view pager has been swiped. What I want is for there to be no need to touch the screen twice in between images two and three.
best solution is to find a view that does the swipe effect without a pager
cause this is a lot of nested views
I've used one before that has done the job
check this library I used it to implement a row with a swipe to show call button and was inside a tabbed activity didn't have any issues

I want to create an image slider using the HorizontalScrollView. Indeed, the slider will display one image at the time and I want to be able to use the fling gesture to navigate left and right in the slider.
Any Idea to which methods to override in the HorizontalScrollView to achieve this.
Thanks a lot.

You could use Gallery with Image Switcher view to achieve this
This Link is usefull to you for better way to implement Android HorizontalScrollView to move image one by one.

You'd be better served implementing this with a Gallery widget or a ViewPager. These elements handle the display and interaction portion for you; you just have to provide the data behind that. If these don't quite work for you, better to customize one of them then start all the way from scratch.
Gallery Docs
ViewPager Docs
You can use any of below things for your need
Gallery - A view that shows items in a center-locked, horizontally scrolling list.
ViewPager -Layout manager that allows the user to flip left and right through pages of data. You supply an implementation of a PagerAdapter to generate the pages that the view
shows.
HorizontalScrollView -Layout container for a view hierarchy that can be scrolled by the user, allowing it to be larger than the physical display
for reference see these links - Gallery , ViewPager and HorizontalScrollView
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.
Is it possible to animate part of an activity launch?
I am not wanting my action bar to animate, however the rest of the view should slide in.
I have tried using a Gallery for this, however I have not been able to animate the gallery while programatically setting the selected view. This is because the gallery does not load more than the currently displayed view and its immediate adjacent views.
When you can use the viewflipper for this. Which shows 1 child at a time. You can set a IN and OUT animation for the views. So when you set the activew view index animations will be applied.
Can someone please tell me how do I create the android phone style picture view in the gallery. That is, when you click on a picture, it pops up as a full screen and you can swipe your finger across the screen and flip through the other pictures in the folder.
How do you create that particular view?
You can use a ViewFlipper to easily switch between different child views and you can use a GestureDetector to detect the swipe gesture.
Override the gallery adapter with a base adapter which has this behavior.
