I'm running into a problem: when I use a non-trivial type of Spinner item, the Spinner displays the drop-down list someplace other than on the Spinner.
(Note: most of this description is identical to https://stackoverflow.com/questions/4188443/android-doesnt-honor-selection-change-with-custom-spinner-items, but the problem I'm reporting here is slightly different. I've split these up so it's clear where to direct different replies to)
My goal was to have a slightly more fancy display for each item in the spinner, and so I started by creating a layout that contains several items, one of which is the target TextView (lbl2, in this case)
I then attempt to set up the Spinner (my eventual goal is to populate the spinner programmatically, so I'm not using resources to set this up) using:
Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = new ArrayAdapter<CharSequence>(
this, R.layout.spinner_fancy, R.id.lbl2);
adapter.add("Item #1");
adapter.add("Item #2");
adapter.add("Item #3");
spinner.setAdapter(adapter);
When I run the program it looks (mostly) good - the Spinner is, in fact, rendering the goofy-looking multi-color, vertical layout of three textviews for each item, and it's correctly substituting Item #1, Item #2, and Item #3 for lbl2. I can even click on the spinner & bring up the drop-down list of choices.
This problem is that the items aren't displayed over the spinner. Instead they're just kind of floating over the activity, a bit further down. Hopefully this picture will help clarify: Floating Spinner Elements http://www.freeimagehosting.net/uploads/bf9f584156.png
EDIT: Thanks for the vote up - I've fixed up the image so it's now inline!
Android Spinners work in that way... The list of items is shown in "dialog mode".
You can add a title to the list using this in the XML layout (in the spinner section):
android:prompt="Select a fancy item..."

I have an android application with a drop down list which have left and right icon, I try to use spinner with left and right drawable, but does not work, what I need is look like below where user can only enter (select) from the list, which mean autocomplete text is not useful, also dropped list does not contain image, How can I achieve that?
So after better understanding your idea, this is the steps you need.
create a custom adapter (this should take the list of string you want to display and the list of icons )
list item is one edit text like
<EditText
...
android:drawableLeft="#drawable/my_icon" />
create your spinner and set the adapter
Spinner sp = findViewById(R.id.spinner);
sp.setAdapter(your custom adapter)
add the item selected listener and you are done.

I have set a dynamic value in a spinner . I am using following code for the same.
spinner_generalbooks.setAdapter(new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_spinner_item, new String[]{"Author","ISBN","Keyword","Title"}));
It is working fine, but I have a problem with the view of the spinner . If we select simple_spinner_item, it is ok in normal state, but when we want to change it, the rows are very narrow and not CheckedTextView whereas in normal spinner options comes with CheckedTextView. If we select simple_spinner_dropdown_item, the options come with CheckedTextView, but in normal state, it looks different as in the pic
(First one is default spinner and second one is using simple_spinner_dropdown_item).
I want to show the spinner just like as default spinner. How to make it?
Android will take the layout specified in the adapter and use it for the control and the items unless you specify the view-resource separately. The way through this is to set the layout to simple_item in the ArrayAdapter constructor and then set the layout dropdown_item separately in a call to setDropDownViewResource().
ArrayAdapter newAdapter = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_spinner_item, new String[]{"Author","ISBN","Keyword","Title"});
newAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner_generalbooks.setAdapter(newAdapter);
If you whant to customize the visual of your Spinner, it'll be more simple to create your own component. A spinner is just a Layout that contains text, image and that display a list in a popup. Create a custom layout for your item and use a new BaseAdapter object to bind your datas.

hope i could help
When my items contains English and/or numeric signs, it shows the radio selection near the item, but when it doesn't contains any English and/or numeric signs (contains only Hebrew in my example) it does not show the radio selection near the item.
For the adapters (array adapter) creation i used the layout "android.R.layout.simple_spinner_item"
And before setting the Spinner adapter I did
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
The solution I found for now, is set the layout to "simple_dropdown_item_1line"; this solves the problem by not showing the radio button.
Any ideas on how to get the radio button visible always?
correction - the solution does not work. for few of my spinners it shows a white text on a white background.
Hi the below code works for me in hebrew
For the Adapter use android.R.layout.simple_spinner_item
and myAdapter.setDropDownViewResource(android.R.layout.select_dialog_singlechoice);

Use an appropriate layout for the drop-down view resource. android.R.layout.simple_spinner_dropdown_item should always work. If you create your own layout, and it does not work, identify where you changed things from android.R.layout.simple_spinner_dropdown_item that would affect matters (e.g., text color, background color).
I have a spinner with data content, but the spinner is very small. How can i put the spinner diferrent?
I guess you're talking about the "drop down" item list (in the other case you would just have to change the size of the Spinner in the xml file).
You have differents way to set the Adapter actually, for example, when you declared your ArrayAdapter (or another Adapter), you can set a layout to put data in a View.
See Android.R.layout
For example : "simple_spinner_item" is really small so you'd rather use another one like "simple_dropdown_item_1line"
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item,spinnerArray);
Can you show us some code if this is not what you are looking for ? I'm not sure of what you are talking (if it's the Spinner element or the list)
I have an android spinner that's populated by a list of strings using an ArrayAdapter and it operates fine, however because of the way the spinner is displayed I'm running into a display height problem with the list items.
At first glance, it would seem that the ArrayAdapter can use a single layout for displaying options which leads to the problem I'm having. When displaying the current item in the spinner (when the user is not selecting a new item from the list) the spinner pads the text so that the spinner is a reasonable size for clicking on. However, when the user taps on it and brings up the list to select a new item, the list items presented are way too small height-wise. If I use an item layout that presents the list items at a reasonable height, then the spinner itself becomes exorbitantly huge due to its own padding of the list item.
Any ideas on how I can manage the height of these two item display modes so that effectively they display with the same height value instead of the spinner height being larger than the list item display height?
I've run into this issue myself a while ago, and it turned out that I need to use different layouts for dropdown and display
I have this code:
adapter = new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, cGroups,
new String[] {
"name", "_id"
}, new int[] {
android.R.id.text1
});
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Yes, the above answer is correct.
It took me forever to find this, because it's wrong in the sdk samples for 2.2 Android. And I had a hard time accepting that.
Here's a snippet from
samples/android-12/Spinner/src/com/android/example/spinner/SpinnerActivity.java:
this.mAdapter = ArrayAdapter.createFromResource(this, R.array.Planets,
android.R.layout.simple_spinner_dropdown_item);
while it should have android.R.layout.simple_spinner_item there instead and simple_spinner_dropdown_item should only be used for the dropdown items. Otherwise the spinner arrow get streched and it draws dropdown selection circle to the display, too.
