I need something like comboBox in android that have DisplayMember and ValueMember but for RadioButtons. I have a form that user should select one item, and I want to save the selected item in database. (the code of selected Item).
What should I do?
Take a look at Spinner,
Here's example about it http://developer.android.com/guide/topics/ui/controls/spinner.html
If u want something like radiobutton but can choose only one, use RadioGrop.
Or you can create your own dialog with radio button.
You can use setSingleChoiceItems property of alert dialog, which have radio buttons as you needed in question.
Check this example, it may help you.

I am looking for some guidance on how to develop the following spinner dialog shown below in the screen shot. It is present in your your android phone's Settings->Display-> Font Size option.
I have been able to implement a spinner with a simple CheckedTextView for each row.
But I am looking to develop something more specific as shown below.
I have searched all over the place for custom spinners.. but most of the show me how to add images etc to each item in the dropdown.. but nothing specific like this... where I have to "pre select" an item based on what is already chosen.
Some questions I am grappling with are....
1) Are those simple radio buttons beside a text view?
2) How would I know which item to "set selected" when I open the spinner dialog? Because my code would reside in my adapter, where my spinner would be in my Activity/Fragment.
3) How would I put a cancal button in a spinner dialog which dismisses it?
Thanks.
I had created a custom DialogFragment and inside onCreateDialog i am creating AlertDialog and showing it.

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
Assuming some logic that deals with measure units and the user is asked to choose between US and metric systems, what would be the better UI choice: using 2 CheckBoxes or RadioButtons? Is there an easy way to ensure just one View is checked?
Checkboxes are useful when you want the user to select multiple options.
Radio buttons are useful to guarantee a single option among multiple options. However, if you have a fair amount of radio buttons the user interface becomes a mess. Therefore, for those cases, Spinners are the best answer for your problem.
If you use Radio Buttons you can guarantee they only use one radio button using RadioGroups.
I would use a Spinner if I were you. It'll allow you to add other unit systems in the future.
Through radio button group you can do it. Just use a RadiobuttonGroup widget mention your radiobutton properties.
Simple. If you can't follow some of procedures I suggest going and look for tuts on them
First: Go to your xml file
Second: Create Radio group
Third: Create Radio button in between
Forth: make sure you have the id of the radio button.
fifth: call the item on your main class. RadioButton name = (RadioButton)findViewById(R.id.radioButton Name);
Now you can program the rest everything really just follows this order for anything in .xml. You need it call it and create and ID simple. Next time just look at youtube vids. I recommend the website TheNewBoston.org best tuts you'll ever encounter in a life time for almost all programming languages.
With the DatePickerDialog we can have a fancy interface to set the date as this
(source: androidpeople.com)
I like it but it can only be used to set date so how could I build a "DatePickerDialog-like" AlertDialog?
I mean users could click on the "plus" and "minus" button as well as put in the number with keyboard.
Instead of only being able to select a single date, I'd be able to select three different numbers using the three up/down/scroll controls.
Alright, here you go, check this out. Then, check out Android Custom Dialogs, which would allow you to make your own custom dialog.
Check out this project for more information
Make an EditText field that they can edit with a button to the right which says Pick a Date and pops up a dialog. If the user selects the popup dialog, fill in the EditText with the result.
You can make a custom view with a "+" button, an edittext and a "-" button. Make a custom dialog with that view. Read about Android Custom Dialog. I hope I helped.
I have a dialog with a listview, the first dialog is for selecting an item and the second one is when you edit the dialog. The first one uses a standard dialog box with no custom layout but for the second one I had to use a custom layout to get the picture in place (if anyone knows how I can populate a standard multiple choice dialog with an typed arrayadapter and item template let me know :)). The first dialog looks like standard dialog should look like but how can I get the second one to look the same with white background, lines between the items etc and be sure it always looks like the standard one even when that one is changed.

For the same, you need to use setMultiChoiceItems while creating dialog. I hope this example helps you: Android Multi selection dialogs
