You can find the official documentation here
This is a Spinner.
Spinners provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one.

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'm searching for a widget in a android app where the user can select a item from a specific list. it's only possible to select one and the list is defined by the app.
it's like a dropdown. I can't use a simple listView because I need at least 4 of there controls on one page. so what is a good solution?
I think, you are looking for something like Spinners
Spinners is what you are looking for.
You can use Spinner in android for dropdown.or you can use AlertDialog as like that of drodown.For using spinner read this.For using AlertDialog read this
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.
I have a range say,1-100 and i want the user to select a value from this range.Ofcourse showing this with a spinner will be awful.I want to use the functionality of date widget,where we can pick a date by pressing a +/- sign,the longer the press ,higher the iteration speed.
I found numberpicker.java that has the code the date widget uses to get this functionality, but do i have to paste that entire code to achieve this functionality!
Here is a tutorial on how to pull out NumberPicker; I've followed it myself: http://www.quietlycoding.com/?p=5

Unfortunately, yes, plus perhaps some resources as well (I have not looked at that code recently). I am not aware of anyone who has pulled that out to make a reusable component, and it is not a widget in the SDK.
Sorry!
