Android :: Spinner - Don't Display Selection / Set Selection Text Color As Transparent?
Aug 4, 2009I'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 RelatedAndroid :: Call Spinner's Value - Use Other Values Based On A Spinner's Value
Jan 25, 2010I 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 :: Using Spinner Selection As A Value
Nov 20, 2010I 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 RelatedAndroid :: Spinner Selection Box On Activity And Dialog
Jun 22, 2010I 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 :: Empty Spinner Before First Selection / Setup It?
Aug 21, 2010I 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 Control - Differentiating Between User Selection And Initialization
Jun 12, 2009I'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 :: Desnity-Based Resource Selection?
May 27, 2010I have a graphic (test.png) of which I need to include density- specific versions, so I put a large (150 X 150) version in res/ drawable-hdpi, and a smaller (100 x 100) version in res/drawable-mdpi. I then include an ImageView, and set the src attribute to @drawable/ test. In the Eclipse Layout editor I can change the configuration between mdpi and hdpi configurations and the correct version of test.png is displayed. Unfortunately, when I compile and load onto a device, the mdpi version is always chosen. The only time the hdpi version is chosen is if it is the only option. I have tested this on the Droid and EVO 4G, which are both running Android 2.1 Update 1, and also the emulator with the same results. For what it's worth, I have also tested on a Motorola CLIQ (running Android 1.5) and an Ion (currently running CM 5.0.7) and they get the mdpi version (as expected, since they are both mdpi devices).

Android :: Spinner Widgets Look Different On Different Devices - Can Define Own Spinner That Looks Same On All Handsets
May 20, 2010I use this code to generate a spinner in my app:

Android :: Popup List Like Spinner Without Spinner
Jan 25, 2010I 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?

View 2 Replies View RelatedAndroid :: Alternative Way To Grab Progress On Multipart/form Upload
Jul 14, 2010As described in this answer you cannot grab a progress of a multipart/form POST upload in Android using only the Android SDK, because there is an issue with the stream buffering when using HttpURLConnection which will be fixed post Froyo (see http://code.google.com/p/android/issues/detail?id=3164#c6).
Since the Apache HttpClient 3.1 was removed from the SDK quite early and the new HttpClient, which is now part of the SDK, wasn't adopted completely (it misses multipart capabilities) you can add the missing parts (specifically apache-mime4j-0.6.jar and httpmime-4.0.1.jar) to perform a multipart/form-data upload AND grab the progress of the upload (also described in the answer mentioned above).
Now, the reason why I open a new question is, that doing as described leads to an enormous growth of the installed app size (in my case from 170kb to 732kb).
So, the question is: Is there any other way to perform a multipart/form-data upload and grab the upload progress without increasing the app size that much? Are there any other libraries one can use or is there any other alternative way, not mentioned here?
