i am using a list view in which i want to directly shift to particular position when i run my code. i m using listview.smoothScrollToPosition(22) which will show the scrolling effect.. which i do not want to show. i want to directly display 22 position of list view.
i used other methods like listview.setselection(), listview.scrollTo() which doesnt work??
Kindly, help me out
Thank you
setSelection is what I use in a public domain app I develop. You can read the code here. It scrolls the ListView to the position I specify.
Perhaps you could post your code if this method isn't working for you?

I'm creating android tv app but I don't know how to implement endless scroll in Verticalgridfragment, i use ArrayObjectAdapter, can someone help me do that?
I'd love to give you a full answer with oodles of code samples but I'm not at my work computer. Basically you'll implement the onItemSelected listener in your Browse/RowsFragment (it should be something like setOnItemViewSelectedListener() from your fragment).
Then you do a check to see if the currently selected element is within 5 or 10 or 15 elements from the end of the list. If it's within that threshold, then make the request for the next page of your list and call addAll() on your adapter when you get the next page. You can optionally show a "loading card" while the next page request is in flight and remove it when you get your data.
I based my implementation off of this open source project - while it's not perfect it should be enough of a code sample to get your started.
I need to create listview like in this picture. The listview item go over each other like google chrome tabs.. I can move up or down listview item... Could anyone tell me a good advice or tell me examples how should I do this?

You need an iOS passbook style component like CardWalletView
You have to create some accordions type control
Here is a link which will help you

when you close the previous view you will not animate that view to the end you have to keep some margin of 2 to 3 pixels to show view as you want
Another idea is you should create some view and use drag and drop... But also you have to some Math calculation... Try this maybe you can get something
Expanding list views may help you with that. I assume that your list view will essentially expand on click and shift everything below the selected area downwards revealing only the content of that selected tab.
Expanding list views utilize the parent-child methods that would allow you to create a very rough view of what you are showing. Styling and customizing those rough layouts afterwards could very well allow you to get that look you're looking for.
Here are some links that might be useful.

Hello Please help me with an Issue, I have a gallery to which i had applied animation. What is actually does it zoom the current/clicked view.
I want that same behaviour in my listview, for example i have
PLAY
SETTINGS
QUIT
So when i click PLAY it should have a zoom effect PLAY
Please guide me..
The view that you are trying to implement can be done with gallaryview in android. So if you can modify gallery then you can get this behaviour, if it seems tough that just grab the opensource coverflow code and modify it a bit to get desired behaviour
you can have an integer variable to hold, currently focused element in list, and in your adapter's getView method, check this variable with position and on match can return a different view, on focus change, reset position holder value, and call adapter.notifyDataSetInvalidated();
I want to implement functionality where a listview loads a set number of views, but at the end of the scrolling it has a spinner in that view, while it loads more views
the official android twitter app has something like this, where it shows you old messages from your timeline but at the bottom of the list it will load more after running a spinner. you can still scroll up and down while this thread is happening without breaking anything
how would this be done? insight appreciated
i think by spinner u mean blocking screen ?
anyways what u need is pretty common, just search for listview implementation in android
here is one of the link i still had:
http://blog.zjor.ru/2010/12/loading-list-data-asynchronously-in.html
also check this if u really want to go to that extent ;)
https://github.com/commonsguy/cwac-endless
basically, it would probably be something like:
Load some data (use a limit)
When you enter the bindView of your last element, change your limit (may be by joining the cursor to another one)
I saw the Android app "Mobisle Notes Free" implement a really cool ListView, where a row gets moved to the bottom if its checkbox is checked. It's not just a simple refresh, but an actual animation where you see the row travel to the bottom. Does anyone know how to implement this?
You could check out the Android example application “ApiDemos.” It provides you with some source code that can show you how to do widget based animation.
Edit:
I believe it is classes Animation1, Animation2, and Animation3.
