I'm binding a data table into a Spinner. But I cannot set the default selection for the Spinner based on a specified identifier which comes from the id column of the table.
How can I do that?

I have a Spinner whose items comes from an ArrayAdaper, and I want the Spinner to initially show that no item has been selected. When the user clicks on the Spinner it's DropDownView should display just those items available for selection.
I don't want to add an empty/blank item at the head of my list of items because that means that it shows as an avalaible selection in the DropDownView and looks pretty lame. And if a selection is made I want it to be a valid one.
I tried spinner#setSelection(-1); but that doesn't work. The first item remains selected.
I tried setting no Adapter initially (which provides the desired initial view) and had hoped to configure the appropriate adapter in the OnClickListener, but spinner#setOnClickListener throw a RuntimeException saying "You probably want to use #setOnItemClickListener instead". And trying to use #setOnItemClickListener throws a RuntimeException saying it is not valid for a Spinner.
Surely this is a common use case. How can I set the Spinner to initially show as empty?
I'm trying to use Spinner as a button with selection pop-up. Basically I want an icon and when user clicks it - the popup list is displayed and user can make a selection. The Spinner happily accepts icon image as drawable background. Unfortunately when I select a value the text overlays the background. Is it possible to set selection text color as a transparent? Or maybe there's a better way?
View 3 Replies View RelatedI am trying to get a Spinner to work in Android. It displays fine and I can select any one of the options in the list. But how do I transfer that to a string?I would have thought in the code below that 'selected' would hold the selected string, but I get an 'Illegal modifier for the local class YourItemSelectedListener; only abstract or final is permitted' error on the 'YourItemSelectedListener'.What am I doing wrong?
View 1 Replies View RelatedI have a spinner selection box on my activity, but now I want to remove the spinner from the main view and make the selection available by an option from the menu button. How do I get the dialog the spinner shows if I click it without having the spinner? Currently I fill the spinner using a SimpleCursorAdapter like this:
Cursor c = db.fetchAllSets();
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this android.R.layout.simple_spinner_item, c, new String[] { DatabaseAdapter.SET_KEY_NAME }, new int[] { android.R.id.text1 });
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSetsSpinner.setAdapter(adapter);
So now I'm planning to remove the spinner from my activity, add a new button to the menu and in the onOptionsItemSelected(...) show a dialog with the list of available selection - just the way it is right now after clicking the spinner object.
As the title says, i have a Spinner with just a couple of options and a button. I didnt declared any Listener for the spinner, instead of that, what i want is use the button and perform different actions depending on the spinner selected option.
So, i declared a handler in the button option "android:onClick", but once there, i dont know how to access the option selected in the Spinner.
I am trying to have my program grab web content based on "Spinner" selection. I have a "Spinner" and a "button" to execute selected item.
View 1 Replies View RelatedI've implemented a spinner with an OnItemSelectedListener event handler. When I initialize the spinner and when a user makes a selection the even handler gets called. What I need is to determine when a user makes a selection. Is there a way to determine in the OnItemSelectedListener whether the event was triggered because of data initialization, or because of a user selection? Am I going down the wrong path trying to do this with the OnItemSelectedListener? Is there a better way to to capture a user selection event on a spinner control?
View 5 Replies View RelatedI am wondering is there any way to create something similar to spinner but which allows multiple selection. I guess we can select multiple entries from ListView but I don't have much space to show all the entires and also I need to show three different categories on the same Activity which you can select from.
Here is what I want to do:
Category 1:
Category 2:
Category 3:
So I am new to developing android apps and had a question. I have a spinner and based on the selection I was wondering the best way to call another class / layout.Here is my main class
Code:
public class BestBuyMobileActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
[code]....
I hope, my issue would be clear for you from my question title. I have three linear layouts in each row of the list view. One linear layout contains an Imageview and the other two linear layout contains text views. These three linear layouts comprise my list view row. But, to my surprise, the listview default selection(orange colored) does not work when I move the trackball of mouse or when I select it from the phone.

View 7 Replies View RelatedI 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 having an Android view with a Spinner on it. I call a populateSpinner() method to add some default values to it.
I also have a onItemSelected() event which gets called before the view is completed to print.
I would like to run a code inside this block only when the user changes the selected items, not when I add or the form gets created.
I mistakenly selected one of two email accounts on my X -- as being the "Default"
This was a mistake, as I really should have kept the setting dynamic -- so I could chose to send from either account.
Now I can't undo that default setting -- nor can I even switch the default to the other email account.
Here's how I got to the menu in question:
GUI Messaging Icon > Left Menu Button > Messaging Settings > Email > Default Email Account
Anyone know how I can undo this default setting -- and put myself back in the position of being able to select which account to use dynamically?

View 2 Replies View RelatedI 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'

View 2 Replies View RelatedI 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:

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.
