May be FastScroll fits to you?
http://developer.android.com/reference/android/widget/AbsListView.html#setFastScrollEnabled%28boolean%29
You can get it by using Database,manage a table to store parsed data and then display data in listview by fetching it database table,
please refer the link for more about database in android
http://developer.android.com/guide/topics/providers/content-providers.html
I tried to do the same and i ended up putting a list view and a textview into a frame layout and then using touch positions in conjunction with list.setslection() to focus...worked for me ! more here: Replication of Apple's Search in Android
I agree with Sergey Glotov, regarding Fastscroll, please take a look at sectionIndexer interface.
Maybe these links(eg1 and eg2) will help you.

Want to achieve this in Android using ListView and data from cursor (result set returned by a database query).
Popular cities are identified by a flag in the database.
Any suggestion, ideas or third party library would be helpful.
You need to make the List View as Indexable. You can check the below link which I used as well to achieve the same.
Complete library source:
https://github.com/woozzu/IndexableListView
Particular class source:
https://github.com/woozzu/IndexableListView/blob/master/src/com/woozzu/android/widget/IndexableListView.java
You can use customized ExpandableListView and show your data in sorted order by alphabetically. You have to take care about both Group view as well Child view.
Just use section indexes! They're built into ListView
I want to display the ListView items in alphabetical order.
I also want to display the items with a separator.
If any one knows can you please help me on this? Thanks in advance.
There are two basic ways for ordering your ListView:
Use Collections.sort() and have your objects implement the Comparator interface.
If you are using a Cursor to load your data (e.g. from a ContentProvider or database), you can use the SQL to order the data returned.
As for adding sections to your ListView, there are also 2 basic ways to do this. Both methods are very well documented in this blog post by Cyril Mottier.
Good Morning All,
I am creating an application to display List of applications with their data usage.
I want my list to look similar to Traffic Counter Pro on android Market
I have also added the print-screen on my box.net as SOF does allow me to upload image
So Can someone direct me how to create ListView like this?
My second Question related to this how to create a tab style Activity.
Two examples that helped me a lot:
http://www.codemobiles.com/forum/viewtopic.php?t=876
and
http://android-developers.blogspot.com/2009/02/android-layout-tricks-1.html
i hope they are usefull to you.
You have to use custom ListView to embed images and format texts as given in the listview.
check out this example or this example or this example or even this example that gives you good understanding on listviews.
Good luck.
This is ListView which items consist of 4 Views objects, look through the tutorial of how to create ListViews and through the tutorial of how to create TabActivitys. And also use links suggested by #parag.
If you observe the screen shot carefully you can identify that group of these fields are available as list item.
They are
Application Icon
Application Name
Data Uploaded
Data Downloaded
Total Data Usage
So you have to create a layout with these fields as children with appropriate position and Use this custom layout as child layout for ListView.
I hope it may help you.

I think you are looking for Expandable listView. You can check the example here
Hope this may help u..
Building a dictionary application I need a ListView that shows over 100k items. I want to let the user scroll as much as needed.
What's the best practice for searching and showing words?
Is it ok to show 150,000 words in the ListView (for pereformance)?
If not how to add 100 other words after the user reaches to the end of the list?
Currently I show 50 words previous and 50 words next of searched word.
Thank you.
(second answer in response to clarification about performance)
There are different ways to do this based on where your data is.
The best way is to have your data in a sqlite database and use a CursorAdapter. Android then manages the fetching of your data and won't fetch data that isn't currently being shown on the screen.
If your words are in an array in memory, try ArrayAdapter or SimpleAdapter.
The Adapter interface, from which all of the above classes inherit, is designed to provide good ListView performance regardless of the number of objects in the list.
One built-in way to allow fast scrolling is via the fast scroll thumb. In your xml, set:
android:fastScrollEnabled="true"
on your ListView, or try:
listView.setFastScrollEnabled(true)
listView.setFastScrollAlwaysVisible(true)
RecyclerView is very good for this. I have developed an open source library especially designed to scroll through large list with extreme speed. In fact it can move well in excess of 1000 items per second both in single and multiple column layouts You can check out the repo here: https://bitbucket.org/warwick/hgfastlist or you can checkout the OpenGL version here: https://bitbucket.org/warwick/hgglfastlist. Here is a demo video on Youtube: https://www.youtube.com/watch?v=oz7aeAlOHBA&feature=youtu.be
Even if you don't want to use this library, there's loads of code to read through in the demo app that will give you good ideas.
