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 am working on an android application where I need to show some offers in horizontal scroll view. These offers are in the form of clickable buttons.
Here is the list example:
Notes about this pic:
This is a horizontal scroll list of clickable buttons.
This list can have multiple buttons and at a time, we can show only 2 buttons with full width like shown in the pic.
Here is the 2nd pic:
Notes about this 2nd pic:
This show that one button is in the center.
What I want:
I want when user scroll the horizontal list then button that is displayed with full width in scroll view should animate to the center when user removes his hands from scrolling view. With that said, I can scroll by tapping and it should be smoothly but when I leave doing scrolling then the button that seems to come in center should be animated to center position like in 2nd image.
I tried this given solution but this works when I click on a button.
Android : Locating the item at center position of the screen after selecting it ,In the horizontalscrollview
This is exactly similar but I want the button in the center when I
leave doing scrolling.
Any help?
I want to create an Gallery-like View which are same as Gallery widget in android! If I try to use default Gallery with Adapter which is list of small Bitmap, It work nicely! However, there's default focus of Gallery (focused Bitmap is default on the center of screen), I don't want that focus! I want to make my View act as a Gallery but doesn't has default focus!
In conclusion, I want to create a Gallery which focused Item can be at any position of Gallery and that Item doesn't automatically move to center of Screen! How can I do that? Should I inherit from Gallery widget? Or I should create my own View?
Thanks everyone!
Just in case you are still waiting, the answer is ViewPager.
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 build a Listview, each item of this Listview in a layout composed of a Gallery.
On click of an item of the Gallery, I want to translate it to the top of my screen.
Even with setZAdjustment(Animation.ZORDER_TOP); my gallery cell doesn't move outside the gallery.
I assume it's because it can't go outside it's parent view.
Is there a way to do this ?
Thanks
I assume it's because it can't go outside it's parent view.
you are right.
There is no way that you can move that exact view. What you can do is make yourself a new ImageView and add it to your top level layout right over the top of the selected cell. Set its image by calling .getDrawingCache() on the gallery cell. Then you can animate your new ImageView to where ever you want.
Depending on what you want to do with it once it has been moved this might work out for you. But fair warning it is a somewhat convoluted process to achieve the effect you're after
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.
