Is there example android code or sample android app which demonstrate animation of the views while scrolling.
For example. In a scroll view some items are not visible when you scroll the items will start to come inside the screen that time i just want to animate that view.
any help would be greatly appreciated.
Thanks.
Download this app. Here you will find tons of libraries of your use. I also seen the library which your are asking in this app. You will find source code links in the app as well.

Or You can do one more thing
Just add on scroll listener and some more listeners are there by which you can detect which portion of your scroll view is visible.
Then You can add animation to those views.
Try Listview animation library.
Modify it and use.

Hey Every one I am working on a project that requires ListView/RecyclerView items animation in a very unique. Here is the sample app RetailMeNot. The ListView or RecyclerView used in this app is definitely custom and looks pretty cool. Initially, the list show smaller image of a child-item. As the user scrolls up, the child item expands fully to reveal a bigger image and previously expand item collapse/hide and put the next item on top.
Has anyone seen a library or implementation of a similar ListView/RecyclerView?
I really tried hard to make this effect on ListView and RecyclerView but couldn't achieve the required result.....
Any help would be really appreciated, Thanks in Advance!!!
After doing so much search and trying so many example's I finally created the effect with this library. This library has the same expand/collapse effect as RetailMeNot. Just download the library and use it in your project.
Happy Coding!!!
I am working on an android application and want to implement a functionality in which I want to show a layout which will contain Like/Comment of that content at the bottom of the page.
I want this layout to be shown when I scroll up the page and hide when I scroll down the page.
I have scene many applications that have implemented this feature, but I have no idea how to implement this feature in my app.
Please check this link of the app which is giving the same functionality which I want to implenment https://play.google.com/store/apps/details?id=com.midsizemango.materialapps
Please help if anyone have idea here, Thanks a lot in advanced.
You need to do the same thing which happens with fab, first create a class extendingCoordinatorLayout.Behavior<View> and implement it like other fab examples. just remember that it won't work on simple listView and gridView.
Also here's a good detailed tutorial for you.
You Just have to set Scroll-Up & Scroll-Down listener of your Recycler view or Scroll View check Reference link.
Now base on Scroll-Up & Scroll-Down listener set VISIBLE / GONEof your footer view either it is LinearLayout or Toolbar with animation.
I'm trying to figure out the best approach to design a horizontal scrollview from android >= 2.1 with some text over the image that when scroll if end is reached it starts showing the first items again hence carousel behavior.
You can continue scrolling horizontally, forever, and the first item shows up again when the end is reached, for example when scrolling swiping to the left. It can be a view pager with an adapter, a carousel but not horizontal scrollview as it does not support some android device.
Any suggestions would be greatly appreciated.
Why not use a ViewPager? As it is available in the Support Library. I would insist to use ViewPager instead of HorizontalScrollView or Gallery. You can check an example for ViewPager from my github.
UPDATE
To show multiple views inside a Fragment you can use getPageWidth(). Check here for reference.
For future people looking for this, here's an excellent library that fit my needs for a similar problem!

I am using a ScrollView to display a list of items that are inflated on runtime. Like a feed of updates for the user.
While thinking about the options i got to let the user update the view with new notifications I thought about the pull to refresh feature in the twitter app.
Anyone got any idea how and if can it be implemented with a ScrollView ?
Saw there are some implementations for that using ListView but I don't like the idea of changing all of my platform to gain this refresh effect.
There is a solution introduced for implementing pull to refresh for various component which are scrollable like listview and scroollview.
Look at ChangeLog link https://github.com/chrisbanes/Android-PullToRefresh
ListView with just one element can be treated as a ScrollView. You can use the implementation for pull-to-refresh ListView and add just one item in it. I had used this trick in the past.
You can do that. You can increase the top margin of the scrollview when the user moves the finger down and the scrollview it's on it's top. Then on release fire the update and decrease the margin with animation.(You have to create your own animation to pull that off). That's the idea. If you want more particular help ask what you cannot implement.
I'm trying to create a Popupindow in which the views can be changed by swiping. Each view should also be scrollable when larger than the popup window. I also want to move only one view when swiping. I can't find any simple way to do that (the Gallery move several views when swiping).
Is there any widget I missed or do I have to implement everything to achieve that (with ViewFlipper and gesture detection for instance)?
Anybody can help with the best way to do that?
Thanks
I've found and ended up using the fantastic HorizontalPager.
