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.

i am using a recyclerview to scroll between pdf pages for a book app
my problem is : i need a way to stop smooth scrolling for
example swype from right to the middle of screen brings next page if the user stop swyping before reach the middle of screen the application keep current page.
Like this one:
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...
On scrolling down gridView.
I want to scroll my three tabs on top as shown in second image.
And on scrolling up back shows that again like first image.
I have checked paralloid library, but not sure if it solves this problem or not.
Same functionality i found in google+ android app. In profile page on scrolling tab scroll till they reach on top. after that list view scrolls.
GridView already has scrolling built into it, so its children should scroll separately than its siblings by default. No extra library should be needed for scrolling down, although scrolling horizontally is a separate issue.
My project need to insert lots of data,I use scrollview to put them in one page.
Now I want it can scroll the item I press(primary Edittext) to the middle of screen.
I tried to use onFocusChangeListener()+scrollTo() with edittexts,but doesn't work very well.
Is there any better way to do it?
Have an onTouchListener for the scrollview.
When the user touches the screen, grab the x and y coordinates and then simply scroll to that point. So scrollview.scrollTo(x,y).

I'm trying to do something similar to PlayStore app. On the app details page you can see a scroll view which has a horizontal scrolling - "app screen images" and also some details below it like, Description, Reviews, etc...
My Question is: In the PlayStore app, when you scroll the image screen shots horizontally, the vertical scroll is locked and the whole view dose not scroll. Only when you touch and scroll some where below the screen shot images , you can scroll to see other details.
Here is where I'm stuck, Is it possible to do the same with a listView? I have a list view with a custom header View which detects for horizontal scroll gestures, (right to left and viceversa). At that time when the user is touching the header, I do not want the whole view to scroll as a normal listview dose when it has more items. Can some one guide me a solution for this? Check out the PlayStore app in your device for a clear understanding.
Thanks a bunch in advance. I would owe you a drink some day.
Why would you detect the gestures and implement the horizontal scrolling yourself, when there's a special control: HorizontalScrollView which already does this?
I don't know the internal details of Google Play app, but I would put the gallery of screenshots in a custom view, and this custom view to be wrapped in a HorizontalScrollView. Then add this custom view as a header to the ListView (basically how you begun).
As long as the scrolling directions are on different axis - the horizontal scrolling is done on X axis, and the vertical scroll on Y axis - there shouldn't be any problems in holding this.
Post Scriptum:
When you scroll the image screenshots horizontally in the Google Play app, I suppose there's a GalleryView instead of HorizontalScrollView, which can hold this type of transitions.
