Android :: Empty Spinner Before First Selection / Setup It?

Aug 21, 2010

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?

Android :: Spinner - Don't Display Selection / Set Selection Text Color As Transparent?

Aug 4, 2009

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 :: Using Spinner Selection As A Value

Nov 20, 2010

I 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?

Android :: Spinner Selection Box On Activity And Dialog

Jun 22, 2010

I 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.

Android :: Spinner Control - Differentiating Between User Selection And Initialization

Jun 12, 2009

I'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?

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?

HTC Incredible :: Can't Setup POP Account Through Setup Screen

Nov 8, 2010

I was able to successfully setup a POP account through the Setup Screen...in fact when I go back through Setup, I still see the account. The problem is I can't DO anything with it in setup (including deleting it to start over) and it doesn't show up in my Apps window with an icon! I see it on the setup screen labeled "Setup Accounts" but no matter if I tap it or hold it or swipe it or try to hit the menu key, it just sits there. There is a green button with the checkmark in it. I guess what I would think i ought to be able to do is to assign it an icon (or even get a generic one) and find the account listed on my app screen...I'm willing to reset it, but I can't even delete it to start!

Android :: How To Empty The Logcat Buffer

Jul 23, 2010

How can I empty the logcat buffer in Android? I use adb logcat from command line and pipe the output to a file, since the DDMS has a very limited buffer. At the moment, when I restart my app (after fixing bugs etc) the logcat buffer has data from the previous launch as well. Even uninstalling the app does not clear the buffer. The only way I've found so far to clear the buffer, is reboot. This is effective, but would like to know if there's an easier way.
