I am developing android application with socket.io. In this application I connect two user with each other. I have 3 screen, MainScreen, CategoryScreen, PictureScreen. In CategoryScreen I have nested recyclerView. Outer RecyclerView is vertical scrolling, Inner recyclerView horizontal scrolling. When one of user scroll the recycler view second user see scrolling of another user. Also if one of the user press back or choose category second user also should go back(previous screen) or open chosen category. How can I handle collision situation when two user scroll recycler view same time or navigate to other screen in app same time?
In my app i need to scroll user's page to up until the spinners reach the top of screen and then scroll up only postfeed. So posts will be in the scrollview, but what i need to do to stop all page scroll at the spinners on top? Can you give me xml-layout code and java if it necessary too.
My user's page link
I have created an Android app that allows people to select products and to then purchase them. My Product Selection screen uses a ViewPager to allow swiping the screen to display different groups of products. The ViewPager area uses a GridView to display the items.
Some of the items have a large name and therefore is not fully shown so I have added a Marquee feature to the text so that the name of the item scrolls which allows the name to be read fully. In general this feature works fine and the text scrolls as expected.
My issue occurs when swiping the screen; pages 1 & 2 work correctly and the text scrolls as expected but when swiping to other pages the text does not scroll. If a page contains lots of items, I can scroll the page up/down which then seems to trigger some sort of refresh on the GridView and the text then begins to scroll correctly.
I'm unsure why the marquee works for the 1st 2 pages and not the others (unless I scroll up/down to get the grid to refresh); the only thing that I can see is that my Fragments onCreateView() method is called twice upon initialization which seems to load the 1st 2 pages into memory. I've done a search on the Internet and this seems to be a normal process so is unlikely to be my issue.
I was wondering if there was a way to load all pages into memory (instead of just the 1st 2) or a way to force the GridView to refresh upon loading?
Any other suggestions would be great and I will give them a try.
Thanks...
I'm trying to implement an Android swipe transition on an image within my layout so the user can get some feedback while they are selecting the image.
So, the user would ideally place their finger on the image, and drag it right, and have the image track it until the user has sufficiently dragged it far enough right, just like it is shown here (from the Android dropdown menu in the second item):

This should be easily implemented with a ViewPager
I've made an activity that looks a lot like the level select screen from angry birds: there is a grid of button, and you can scroll through pages of them by swiping right or left.
I built it by creating a layout of the buttons, and then adding those layout to a Gallery view.
The problem is the animation is jerky, even if you swipe extra slowly, the content jumps ahead. Even when you fling the gallery page, it skips and jumps along its way to its destination.
I am wondering how to fix this: Maybe the complex layout it making it non responsive during the inflate?
Do you know how to fix this, or of a good way to do a workaround using some other approach that will let me have 3 or more screens smoothly swiping from page to page?
You should be using ViewPager. This is available in android support packages. Gallery Widget will not be smooth if you add components into it which has a lot of touch actions.
