Android : Disable Spinner Item?
Dec 10, 2009
How do I disable (gray out, make unselectable) an item in a Spinner? I tried calling View.disable() on the associated child of the Spinner, but it remains black text (not gray) and selectable.
There must be some way of showing but leaving unselectable certain items in a spinner, right? This is a standard "menu" behavior that goes back decades. Android permits it, right? I want the user to see that certain options are possible under certain circumstances even if they are impossible at the immediate moment...exactly the way items in the main Android menu-button invoked menu can be visible but unselectable.

Is it possible to display particular entries in a Spinner list as disabled?
i.e. I want to always display a spinner with 4 entries (North, South, East and West, say), but I want to be able to disable any one of these so that is appears greyed out and not selectable.
Is this possible, or will I have to recreate the list each time, leaving out the invalid entries?

I need to get an item's position in spinner knowing it's ID. I've tried to do it with Spinner and SpinnerAdapter classes but there are no corresponding methods there.

I am a newbie coder and new to the SDK. I was just playing around with an app that i made. I wanted to know as to how to retrieve the item id of the selected item from the spinner when the spinner is re- populated.
For example, I created 2 spinners, if you selected item 0 from spinner1 then spinner2 will have a bunch of items and if you selected item 1 from spinner1 then spinner2 will have a different set of items. Now, my question is that when i select item 1 from spinner 1 then the items in spinner2 dont have different ids. So how do i differentiate from the two sets of data?
To illustrate,
User selected item 0 in spinner1 -> spinner2 gets data from array1 -> item 0 in spinner2 has id '0' and item text is "apple"
User selected item 1 in spinner1 -> spinner2 gets data from array2 -> item 0 in spinner2 has id '0' and item text is "oranges"
I know this sounds confusing but i hope the right people understood it..

I created two Spinners to display the data in my application. In my first Spinner, the first item of the list is always displayed directly, but in the second Spinner nothing is displayed, even if I click on an item on the drop down view. Can anybody explain this behaviour?
Here is the code...

I have a update view, where I need to preselect the value stored in database for a Spinner.
I was having in mind something like this, but the Adapter has no indexOf method, so I am stuck .
void setSpinner(String value)
{
int pos=getSpinnerField().getAdapter().indexOf(value);
getSpinnerField().setSelection(pos);}

I am trying to get the selected item of my spinner that is populated and I am already seeing the values. when I try to use (String) s.getSelectedItem(); to get the selected item, I am receiving a handler exception on Logcat.
The spinner throwing the error is a 2nd spinner resulting from the 1st spinner's selected item (that works perfectly). In other words, user selects from spinner one and upon selection, populates spinner 2 (until here everything is fine). When trying to get the value of the selected row in spinner2 , I am receiving the error.
here's the main parts of my code...

Its me again. I tried the last hours, how to change content of a spinner. ok, lets start from the beginning.
I have three spinners. They all have initial values. The first spinner is the main spinner and the other two spinners depend on the vale chosen in the first one. So i want to update the last two spinners after making a selection in spinner one. *edit: All spinners are on the same activity.
How can i achieve this? My problem is that i can only make changes in the spinners onitemselectadapter but thats a whole new class. I cannot reach the activity where my other spinners are.

I have a spinner with items, populated via ArrayAdapter. I want to change font style for some (not for all) of spinner items, both for spinner's combobox and listbox. I guess that I need to subclass something, but I don't understand what. How can I do that?

Newbie question. I'm using a SimleCursorAdapter to populate a spinner from an SQLite table, as shown in the Android dev docs. Code...
I've set up a listener, but I can't figure out how to get the selected item text, it pulls up the SQLiteCursor, not the actual text in the spinner.Code...
Google turns up the question on several message boards, but no answers, so it appears to be a common newbie question. It may be painfully obvious to some.

I have a spinner, which mostly works. If a user selects one of the items in it, the 'onItemSelected' routine catches it just fine.
But if a user clicks the same spinner, but does not change from the already visible item that it's currently displaying, the 'onItemSelected' routine just ignores it, and the logs show:-
WARN/InputManagerService(577): Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@437948b0
I there anyway to capture someone doing this? The idea is that my spinner contains a list of names, and when a user selects one from the spinner, it gets added to a listview.
I could just add another button to get the name from the spinner, but, screen-space is already lacking and I'd rather not add anymore content.

In android, I create my menu item like this?
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(0, 0, 0, "Menu1");
menu.add(0, 1, 0, "Menu2");
return true;}
How can I set all the menu item disabled programmically (in another part of the code in my activity, not in onCreateOptionsMenu() method itself)?

In my application has a ListView. When long press on item the "Context Menu" will appear. I want to check the data ID, then set disable/enable to my Context Menu "Items". I can not find out the function like getMenuInfo() or something like this.
@Override
public void onCreateContextMenu(ContextMenu menu , View v, ContextMenuInfo menuInfo)
{ super.onCreateContextMenu(menu, v, menuInfo);
menu.add(0, ADD_FAVORITE_ID, 0, "Check");
menu.add(0, ADD_FAVORITE_ID, 0, "UnCheck").setEnabled(false);}

I use this code to generate a spinner in my app:
code:.........
On my device (Motorola Milestone) and in the emulator this looks like the standard gray spinner widget.
On of my colleagues uses a Motorola Backflip and on his device the Spinner is black. Now its very hard to read the font in the spinner.
What do I have to do to use my own view for the spinner? I don't mind to have the gray spinner on all devices, but it should always look the same on all devices.

I have a spinner 'aperture' set up with a list of numbers, and a spinner 'mode' with two options. When a button is pushed I need a calculation to run using various inputs, including the current selection from 'aperture' and a value derived from 'mode'. How do I call the value of a spinner so I can use it in a calculation?
Also, how do I use the spinner 'mode's selection to set this other value before implimenting it in the calculation? To be more specific, if the spinner is set to Small then the value I use in the calculation is 0.015, whereas if Large is selected I need to use 0.028
My other inputs are EditText views, so right now I am set up like this:
CODE:............
That is not the actual equation, it is just a test to make sure everything connects properly. How would I call the value of spinner 'aperture' and the Small/Large spinner 'mode'

I have a spinner widget in my activity which lets users pick a list name.
Normally, the function of the spinner is to switch between lists but for a couple of instances, I swap out the selection change listener to perform a different function with the same list of options. Once the selection has been made, the old listener is restored and life goes on.
This is a bad and buggy arrangement. Instead, I would like to have a function that just takes a selection listener and some other parameters and shows a popup list that's populated by the same cursor (or and identical cursor) as the spinner, without using the spinner itself.
Is there any way I can do this?

I am trying to populate a spinner depending on another spinner's selected item, my code is the following:
CODE:.................
what is intriguing me is that the first spinner onitemselection works perfectly ( I can see the values in LogCat) then when I change selection of the 2nd spinner I am gettging an error on this line: String selected= (String) s2.getSelectedItem(); So the compiler gets insisde then onItemSelected function of the 2nd spinner but throws an Handler exceltion on s2.getSelectedItem()
why? it works perfectly for the 1st spinner.

I don't know exactly how to explain this problem, but I'll try. I have a ListView with several items. Each item has inside a TextView and two ImageView. I want the ImageView change when I click on them, and I want to open a context menu when I press for a long time into the ListView item.For the ImageView, everything works properly. For the whole item, I can show the context menu after a long press, but my problem is that the ImageView changes as well when I am pressing the TextView, for example.I hope you understand my problem. I think that all the children of a view are affected by an event in the parent, but I am not sure.

Trying to implement simple dictionary. I want to make it so while the user is typing in the EditText box the list to scroll automatically to the best match. I don't want it to filter the list. For example if the user types "s" in the EditText I want the first word that s/he sees under the EditText box to be the first word in the dictionary that starts with "s." But the user should still be able to slide up and down and to be able to see the entire list of words. It is basically like a go to functionality. I used ArrayList to store my list of words. The data is in res/raw/data.xml file. Here is my onCreate method
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
wordListView = (ListView)findViewById(R.id.wordList);
myEditText = (EditText)findViewById(R.id.myEditText);
words = new ArrayList<Word>();
arrAdap = new ArrayAdapter<Word>(this, android.R.layout.simple_list_item_1, words);
wordListView.setAdapter(arrAdap); try {
InputStream inSource = getResources().openRawResource(R.raw.data);
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(inSource, null);
NodeList wordsList = doc.getElementsByTagName("eng-bg");
int length = wordsList.getLength();
for(int i = 0; i<length; i++) {
Element entry = (Element)wordsList.item(i);
Element eng = (Element)entry.getElementsByTagName("english").item(0);
Element bul = (Element)entry.getElementsByTagName("bulgarian").item(0);
Element id = (Element)entry.getElementsByTagName("ID").item(0);
String english = eng.getFirstChild().getNodeValue();
String bulgarian = bul.getFirstChild().getNodeValue();
int wordId = Integer.parseInt(id.getFirstChild().getNodeValue());
Word word = new Word(bulgarian, english, wordId);
addNewWord(word);
} catch (ParserConfigurationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}wordListView.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
selectedWord = words.get(pos);
showDialog(TRANS_DIALOG);
myEditText.setText(selectedWord.getEnglish());
myEditText.addTextChangedListener(new TextWatcher(){
public void onTextChanged(CharSequence s, int start, int before, int count) {
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
