I have a Gallery view, the view is loaded with 10 images. The situation I'm struggling with is when the user scrolls to the end of the gallery how do I load the next 10 images?
I added a "Next" button to fetch the next 10 images the problem with this solution is when I switch the phones orientation to landscape gallery view wont scroll anymore. Plus I read here
that you cannot put interactive controls in Gallery view.
If I implement the onScroll() or onFling() methods then I will be fetching the next 10 images without knowing if the user has reached the end of the first 10 in the view.
Your advice would be much appreciated.
There's a couple of solutions I can see.
First of all, create an image at the first/last spot to change gallery view. onClick() is supported I believe, and you can see the gallery that was selected.
The second is to have the controls outside of the gallery, ie, right below the gallery view.
Hope this helps.

I'm trying to implement my ownt picrutes gallary app. I'm using ImageSwitche for showing big image and Gallery for showing thumbnails. The problem is that when user scrolls gallery it changes selection to thumbnain whic is in the middle of gallery but required behaviour is just scroll like ListView and change image when user tap on thumbnail.
Does anybody have suggestion how to implement such behaviour.
PS. HorizontalScrollView with LinearLayout inside is bad idea becaus of it does not recycle views and holds all the pictures of thumbnails in the memory.
Take a look at the solution I have for my own question here
Basically I ended up with slightly modified version of ViewPager to display N-number of pages instead of just one. The only thing that I don't like about that that you will not have velocity-based scrolling as in ListView
I need to create listview which should displays as a photo slider. I mean that it have to be only one item at the screen. And when user starts swiping up or down item above or below become be visible, but doesn't fill the screen. And when user swipes it at some defined point, this item fulfills the screen. And so forth.
As a photo slider. You open it and see only one photo at the screen. Then you click on the photo and start swipe down. Accordingly to your swiping photo which is in bottom of current fulfills the screen. I want to implement such a principle at my listview items.
I attached the files which can describe what I want to implement. So position 1 - start position of the listview. Then user touches the screen and start to swipe left. You can see that on the 2-nd picture - user sees the item 1 yet, but also see 2-nd item. And, finally, when he swipe over 2-nd item to the end, he sees only it on the screen. I'm sorry for such strange explanation, but I think that it can make my question more clearly.
Besides, I want to implement vertical swiping, not horizontal at my listview and it should be only one item on it.
I am still not sure if I got you, but from what I could gather? Are you looking for a View Pager? If yes, then a nice tutorial is given at this link. View Pager is used in the home page of the google play app. Try opening it and slide right left top bottom and see if thats what you want? Also, from the images it seems as if the headers have been added to the View Pager, that can easily be added by using view pager indicator. I hope i was of some help to you. If you have some doubt please feel free to ask.
I implemented Gallery using Horizontal scroll view by referring some tutorials on google. I tried gallery with gallery widget but its crashing on ics. so i went for horizontal scroll view. I implemented it successfully but i want to limit scrolling of it to 1 image at a time like the way we do in gallery.
Please help me with this.
Its quite more easier with ViewPager. I found now.Pager moves only one item at a time.
I followed
View Pager Example in Android Development
I have retrieved the all the imaged from sd card and displayed in my grid view.On tap on one image icon from the grid it goes to second activity and display that clicked image in the image view.
But now i want to implement that when we flink/swap on image from the second activity then the image should be changed to next/previous.
Please give me solution.
Thanks
What you are looking for is ViewFlipper with GestureDetector. Here are few links which will get you started with.

And once you understand the concept, make use of answer here.
gesture Detector is used to detect fling events and view flipper to flip to next element.
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.
