Add To Spinner From Array

Dec 5, 2011

I've added a spinner to one of the pages within my app. When the page(activity) loads it calls a web service and the values that are returned need to be displayed within the spinner.

I've found lots of examples where you can add values from an array but the array values are always hard coded. I need to be able to add whatever is returned from the service into an array and then add that to my spinner.

Is this possible?

Android :: Look Up Position In Spinner From String Array?

Aug 24, 2009

I have a pretty simple question, but I am still hammering my brain with finding an elegant solution.

I have a spinner filled with an array defined as xml resource:

<string-array name="distances"> <item>item1</item> <item>item2</item> </string-array>

Whenever I close the application I save the selected string of the spinner in a database. E.g. I save "item1".

On application restart I now want to reload the spinner with the previous selection. Therefore I read "item1" from the db and now have to somehow lookup the position of it and there I am stuck. An additionalproblem is that the array might have changed from the time where the data was saved to the db.

Android : Spinner Cannot Load An Integer Array / Way To Fix

Android : Way To Create Spinner Programmatically From Array

May 6, 2010

I'm all new to Android and I'm trying to create a spinner programmatically and feeding it with data from an array, but Eclipse gives me a warning that I can't handle.

Here's what I got:

This ArrayList holds the elements that should be in the spinner (gets filled from a file later on):

ArrayList<String> spinnerArray = new ArrayList<String>();

This is code ...

Now the second line (ArrayAdapter...) gives me a warning in Eclipse saying "ArrayAdapter is a raw type... References to generic type ArrayAdapter<T> should be parameterized", I have no idea how to fix this (or what that means in the first place :) ).

It's just a warning and the App seems to run alright, but I'd still like to understand what's wrong and fix it.

Android :: Spinner Widgets Look Different On Different Devices - Can Define Own Spinner That Looks Same On All Handsets

May 20, 2010

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.

Android :: Call Spinner's Value - Use Other Values Based On A Spinner's Value

Jan 25, 2010

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'

Android :: Popup List Like Spinner Without Spinner

Jan 25, 2010

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?

Android :: Spinner Display The Radio Button In Textview?

Oct 27, 2010

i have a spinner with an arrayadapter that is dynamically managed. when it gets displayed, the spinner text also displays the radio button. how do i get rid of this radio button?
NOTE: i'm not talking about the radio buttons that appear in the list that is displayed when i select the drop down on the spinner.

here is a pic of what it looks like: SIGH cannot upload image as i don't have 10 pts. so i've found a link: http://www.slashresources.com/android-gui-examples/ scroll down about 1/2 way and find the spinner example on that page. and my spinner looks like the spinner thats grayed out by the list. notice how the drop down arrow is all strecthed and yucky... thats my problem.

Here are the appropriate code snippet... couple of points:

This code is in the constructor of widget which is a subclass of Spinner value is an array of Object instances (passed when the widget gets created) there are no XML resources; all widgets are dynamically created thinking i need to "manipulate" the prompt, i added setPrompt(...) in the constructor and also in the onitemclicked event listener... this had no effect.

Q: what am i missing? seems to me i'm missing some attribute of the Spinner which is causing the radio button to also display in the text part of the spinner.

CODE:............

Android :: Use Spinner To Hide / Display View Objects?

Sep 26, 2010

For an Android application, I'm trying to use a Spinner which, when an option is selected, will hide/display relevant View objects. For my application, these objects are an EditText and an associated TextView label for the field. Unfortunately, I can't seem to get the EditText to hide/display, and when I add it code to hide/display the TextView, I get a NullPointerException. I presume that since I am laying out the view objects in a RelativeLayout, by hiding one of the view objects, I am removing its relationship with other view objects, hence the NullPointer.

Can anyone figure out why this might be happening? Here's my code...

Android :: Setting Values And Display Text In Android Spinner

May 31, 2010

I need help in setting up value and display text in spinner. As per now I am populating my spinner by array adapter e.g. mySpinner.setAdapter(myAdapter);

And as far as I know after doing this the display text and the value of spinner at same position is same. The other attribute that I can get from spinner is the position on the item. Now in my case I want to make spinner like the drop down box, which we have in .NET. Which holds a text and value. Where as text is displayed and value is at back end. So if I change drop down box , I can either use its selected text or value. But its not happening in android spinner case.

For Example:

Text Value
Cat 10
Mountain 5
Stone 9
Fish 14
River 13
Loin 17

So from above array I am only displaying non-living objects text, and what I want is that when user select them I get there value i.e. like when Mountain selected I get 5. I hope this example made my question a bit more clear.

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?

Android :: How To Pull Strings From Array For Clicked List Item?

Aug 4, 2010

I have an array adapted listview (the array adapting is done in another class). I just got the click listener working for the list but now I want set it up so that when I click an item. It pulls the strings from the clicked item and piggybacks them on the intent to a new activity. I figure I am supposed to use intent.putextra however I am not sure how to pull the correct strings corresponding to the item that i click on. My code is below. I am simply lost to be honest

//Initialize the ListView lstTest = (ListView)findViewById(R.id.lstText);
//Initialize the ArrayList alrts = new ArrayList<Alerts>();
//Initialize the array adapter notice with the listitems.xml layout
arrayAdapter = new AlertsAdapter(this, R.layout.listitems,alrts);
//Set the above adapter as the adapter for the list
lstTest.setAdapter(arrayAdapter);
//Set the click listener for the list
lstTest.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView adapterView, View view, int item, long arg3) {
Intent intent = new Intent( HomePageActivity.this, PromotionActivity.class );
finish(); startActivity(intent); } } );

my alerts class..
public class Alerts {
public String cityid;
public String promoterid;
public String promoshortcontent;
public String promocontent;
public String promotitle;
public String locationid;
public String cover;

@Override public String toString() {
return "City: " +cityid+ " Promoter: " +promoterid+ "Short Promotion: " +promoshortcontent+ "Promotion: " +promocontent+ "Title: " +promotitle+ "Location: " +locationid+ "Cover: " +cover+ "$"; } }

anddddd my alertsadapter class..
public class AlertsAdapter extends ArrayAdapter<Alerts> {
int resource;
String response; Context context;
//Initialize adapter public AlertsAdapter(Context context, int resource, List<Alerts> items) {
super(context, resource, items); this.resource=resource;
} @Override public View getView(int position, View convertView, ViewGroup parent)
{ LinearLayout alertView; //Get the current alert object Alerts al = getItem(position);
//Inflate the view if(convertView==null) {
alertView = new LinearLayout(getContext());
String inflater = Context.LAYOUT_INFLATER_SERVICE; LayoutInflater vi;
vi = (LayoutInflater)getContext().getSystemService(inflater);
vi.inflate(resource, alertView, true); } else {
alertView = (LinearLayout) convertView; }
//Get the text boxes from the listitem.xml file
TextView textPromo =(TextView)alertView.findViewById(R.id.txtPromo);
TextView textPromoter =(TextView)alertView.findViewById(R.id.txtPromoter);
TextView textLocation =(TextView)alertView.findViewById(R.id.txtLocation);
//Assign the appropriate data from our alert object above
textPromo.setText(al.promocontent); textPromoter.setText(al.promoterid);
textLocation.setText(al.locationid); return alertView;

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?

Android :: Refreshing A Spinner

Jul 3, 2010

I have a view with a spinner. The activity starts another acvitity with a popup where I add or delete values that the parent shows in the Spinner.

So, in onActivityResult() I refresh the content of the Spinner so that it reflects any additional or deleted values, by calling my fillSpinner() method.

The parameter to this method is the previously selected value:

CODE:..........

When I open the Spinner, it contains the correct list (i.e. it was refreshed) and the correct value is selected. However, the Spinner control itself (in its closed state) does not show the selected value, but the first in the list.

When I step through the code in the debugger, the Spinner value is correct before and after I call setSelection() (and it is always called with the same correct id). However, since I cannot step out of the event, when I resume the execution after a short moment the value in the Spinner changes.

In other words, the spinner's displayed string is changed and is different from the selected item when I return from my popup activity.

Android :: Custom Spinner

Mar 9, 2010

The default drop down view of the spinner occupies the entire width of the screen. I tried to create a custom spinner which occupies only some portion of the width of the screen, but I'm unable to do. I want to see the objects behind the drop down. Here is what i tried, I changed the drop down view as,

adapter.setDropDownViewResource(R.layout.simple_spinner_dropdown_item); instead of

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_it­em);

In the layout.simple_spinner_dropdown_item.xml file I specified the width, but it still occupies the entire width. Can any one help. Is there any other view which is similar to spinner but I should be able to see the background objects like a alert dialog. Is it really possible?
