I am working in android. i am trying to display name of university using listView.
my list view is looking like this.
Now i want to add a search bar on the top of this list view. if i press A in search bar then this list view should display all the name of university start with A, if i press some other character then according university name must be displayed.
Please tell me how can implement this. Is any way to make search bar in android. I have seen in iPhone, it works very efficiently in iPhone. Please help me how can make this search bar ?
Thank you in advance...
This may be the long way. but this is just an idea..
I think you have to create a layout xml file with one EditText and ListView. Inside activity you have to listen for textChange in EditText and then probably you have to filter your ListAdapterbased on the text entered by the user and bind it with ListView.
See the complete example here : http://www.androidpeople.com/android-listview-searchbox-sort-items
You can use setTextFilterEnabled(true) on your list view.
I think this may help you to get an idea. http://developer.android.com/resources/tutorials/views/hello-autocomplete.html

I want to show suggestions not only as starting character but also a containing character... means 's' suggestions should be like tags,pas,also, and so on.
#sagar jagdale :
You can use Android AutoCompleteTextView.
It provides suggestions automatically when the user is typing. The list of suggestions is displayed in a drop down menu from which the user can choose an item to replace the content of the edit box with.

how can I create in my android app a button that will automatically put the search suggestion into the search bar, so that when you click on the button, the search bar will be automatically filled with the corresponding text?
An example is shown in the image below.
Have you looked into AutoCompleteTextView? From the docs:
The list of suggestions is displayed in a drop down menu from which the user can choose an item to replace the content of the edit box with.
EDIT: If you're using a SearchView, the process is much different. Assuming you've already set up the SearchView, you have to provide search suggestions that the system will display as the user types. These can be recent query suggestions or custom search suggestions.
There are several steps involved, but in a nutshell, you will have to create a Content Provider that takes a search query and serves up a list of suggestions (details here). Once you've done this, you can configure your search bar to fill itself in when the user selects a suggestion (details here).
Hope this helps!
The solution is to call setQueryRefinementEnabled(true) on the SearchView object
I have used this forum when I didn't know how to do something, but now I have decided to begin participating in it.
I would like to know how could I do a dropdown text (maybe it has a specific name and that's why I don't find any results on the internet). I mean, I have some tags in the screen (About, Company, Contact, ...). Each of these tags has a down arrow on the right side, and when I click it, it has to display (and hide if it's clicked again).
Here are the links with the images of what I want to do.

Thank you in advance!
You should use an ExpandableListView component.
There is a tutorial for it here.
Finally I did it with ImageViews and TextViews using the property android:visibility. Now that it's a static version is working properly. I hope that it continues working well when taking the information from the DB
I am new to android. I was stuck on a problem but I finally solved it.
I was using a TextField instead of CompleteTextViewField so whats the difference between these two and when should I use each one of them?
Thanks
Neither of those classes you mention (TextField, CompleteTextViewField) exist. Do you mean EditText and AutoCompleteTextView? I think the documentation explains it pretty well:
[AutoCompleteTextView is] An editable text view that shows completion suggestions automatically while the user is typing. The list of suggestions is displayed in a drop down menu from which the user can choose an item to replace the content of the edit box with.
That is, use it rather than a normal EditText if you have a set of common autocompletions for what gets entered in the box. The docs also link to a full sample that shows how to populate that list of suggestions with an Adapter.
friends,
i want to perform functionality same like stackoverflow tags as we do normally creating a question separated by commas in android.
i know we have auto complete text view in android any one suggest me can i use it for multi selection?
or any useful way to achieve this?
any help would be appreciated.
it can be achieve through two ways
i devised my own machanism so may b you people have better approach than me please share too.
1) simple
2) advance
1) in simple we can use autocomplete text view and only use single tag with hard coded values which is limitation.
2) i have used a popup page with a Edittext and add button on top and listview with checkboxes below it.
fixed items i have already loaded into list view with checkboxes so that i could select multiple tags.
and in case of if i want to add my custom tag then i use that edit text above list view and store it in temporary data and
then finally using bundle i show selected values where i want seperated by commas.
thats it.
