Android :: Disappearing Dividers In Spinner Drop-down List
Sep 24, 2010
I am writing my first simple Android App: It loads temperature samples from a Java based measurement system (CSV via HTTP), shows the available channels in a Spinner and when a channel is selected, it shows the corresponding value and a timestamp in two TextViews. The App works fine, except a little cosmetic problem: The items in the drop-down list are separated by a horizontal line (divider) and depending on the scroll position, some lines disappear and appear again, when I scroll some more pixels up or down. The phenomenon happens on the emulator screen as well as on the handheld display (HTC Wildfire). Seems to be a screen resultion problem. Does anyone have a hint how to avoid this?
See my code below...

I 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:

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?

In an application I have a Spinner that has tens of items.When the user taps on the spinner, a popup dialog appears that shows the list of possible selections. However, since there are (sorted) tens of items, I want the user to be able to use the fast-scroll thumb (like fastScrollEnabled attribute on ListView), similar to the one enabled in Contacts application.I tried to get the ListView that is used in that pop-up dialog, but I didn't find any methods to do that.

I have an AutoCompleteTextView defined as the following inside a RelativeLayout,
<AutoCompleteTextView android:id="@+id/edit_tag"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/tag"
android:inputType="text"
android:imeOptions="actionNext" />
When I touch on a choice from the drop down list, instead of setting the text of this view to the one I chose, it clears the view as if no text has been inputted. I tried to debug this and walked through the execution of the program step by step. It seems to have been cleared at around line 123 in Looper.java, which I cannot see the source.

I am trying to change the text color of the spinner list items individually. I would like to be able to color the top three texts black and then the bottom four grey. This way the last items look disabled, but I still want to be able to capture the event when they are chosen. I haven't been able to find any documentation on how to do that. Alternatively I would like to disable som list items, but still be able to capture the event when they are chosen.

Is it possible to set the width of a spinner dropdown list in code? I have a spinner populated with integers, and it does not look good with the list expanding to full width. Can I set the width to wrap the content somehow?

When I try and send a new message, or forward a message some of my contacts don't show up on the drop down list. I'll type the first few characters of their name and it will bring up a list of the names in my contacts directory but some names are missing so I cannot send a text in the normal manner (I know I can find the contact through the dialler and send a message that way but that doesn't help if I try and forward a message). I've looked to see if there are any strange spaces in the names etc but I cannot fathom out why some of my contacts are missing from the drop down lict in messages. Anyone else have this problem or know a solution?

Is there a way to replace the standard ListView that pops up when opening a Spinner with a custom one?
I would like for my Spinner list to be Filterable (and/or even possibly have two tabs with different lists the user could select options from). Is this achievable or do I have to do my own implementation alltogether?

I have a question regarding a feature that just seemed to disappear from Handcent SMS.
Before, when I composed a message in the app or using quick compose (long press search button), there would be a drop down list of possible choices when I began typing in the "To:" field. For example, if I typed "k", it would show names beginning with "k". But now the feature is gone and it really sucks when I want to compose a text.
Does anyone else have this issue? Is it Handcent's problem or a software problem (v2.1 bug?), and does anyone know how to fix it?

Is the android:divider attribute under the TabWidget working? I tried the Tab Layout tutorial from android just to test (http://developer.android.com/resources/tutorials/views/hello-tabwidget.html) and set the android:divider to some image (for now I used the android vertical scrollbar as the drawable to really emphasize if its getting picked up (copied it from frameworks), but when I ran it on the emulator, it doesn't appear to be working. According to the docs, the TabWidget does seem to support this attribute: "Drawable used to draw the divider between tabs." I am using a nine-patched drawable as my divider image drawable.

I'm building a list that is sorted alphabetically. The list should show a divider containing the Letter that the following icons belong to.
I'm using a Cursoradapter that contains the already sorted result from the database. I plan on adding the divider to the list item and set it to visible if the shown letter changes. How do I know that I have a new Letter? Is there a better way then going forward or backward in the cursor and check if the item I show is the end or beginning of a new group?

I need to completely remove dividers from ExpandableListView. As for parent items it's a setDividerHeight method where I can pass a zero value. But there's no similar method for child divider. Is there any way to hide it?

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'm using a ListView with a custom ListAdapter and a custom Drawable as divider.
My list contains active elements and passive ones as well. By default, the ListView draws a divider only between two active items. This is exactly what I want it to do, expect that ListView leaves "dividerHeight" pixles free space above and under eacht inactive item. Because my ListView has no background-graphic (which is on purpose and can't be changed) I see slices of the underlying Views through my list.
If you have any dificulties imagining what this means, have a look at http://brianschimmel.de/divider.jpg
I'm rather sure this is a Bug, but maybe it's the intended behaviour. I wanted to hear your opinion (as well as a workaround, if there is any) before filing a bug at b.android.com I can even imagine a reason for the behaviour as it is: If you wanted to make list items active/ inactive at runtime, the current implementation does not change the positioning of the items, while the behaviour I proposes would do. But I'm not sure if activatin/inactivating items is a real need.
I'm thinking about not using the build in divider feature at all and inserting a special "divider item" between each two active items manually.

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'

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 just rooted my moto droid. Now I am wondering if it is possible to drop 1.5 or other versions of the OS on the phone and if so how? If anyone could explain how I do this or link some forums that explain this. Or is there maybe a dual boot option b/c I don't want to always us 1.5 only for testing purposes.
