I am a newbie coder and new to the SDK. I was just playing around with an app that i made. I wanted to know as to how to retrieve the item id of the selected item from the spinner when the spinner is re- populated.
For example, I created 2 spinners, if you selected item 0 from spinner1 then spinner2 will have a bunch of items and if you selected item 1 from spinner1 then spinner2 will have a different set of items. Now, my question is that when i select item 1 from spinner 1 then the items in spinner2 dont have different ids. So how do i differentiate from the two sets of data?
User selected item 0 in spinner1 -> spinner2 gets data from array1 -> item 0 in spinner2 has id '0' and item text is "apple"
User selected item 1 in spinner1 -> spinner2 gets data from array2 -> item 0 in spinner2 has id '0' and item text is "oranges"
I know this sounds confusing but i hope the right people understood it..
I created two Spinners to display the data in my application. In my first Spinner, the first item of the list is always displayed directly, but in the second Spinner nothing is displayed, even if I click on an item on the drop down view. Can anybody explain this behaviour?
I am trying to get the selected item of my spinner that is populated and I am already seeing the values. when I try to use (String) s.getSelectedItem(); to get the selected item, I am receiving a handler exception on Logcat.
The spinner throwing the error is a 2nd spinner resulting from the 1st spinner's selected item (that works perfectly). In other words, user selects from spinner one and upon selection, populates spinner 2 (until here everything is fine). When trying to get the value of the selected row in spinner2 , I am receiving the error.
I am trying to change the items in a list view based on a value that gets selected in a spinner that is in the same activity. Is there a quick way to do filtering on the list adapter data based on that value, or should I go the long way of changing my adapter implementation for easy filtering?
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 have an xml layout file which contains a few widgets including a Spinner I want to display a list of strings in the spinner, the list is generated at runtime as a result of a function so it can not be in arrays.xml.
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:
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'
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.
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()
I want to display list of items in my application and user will select checkbox which is present in front of each item. List is displayed well. It also shows checkbox infront of list item but when I click on checkBox it is not getting selected. My code is like this .........................
When a wallpaper is set (either from the Wallpaper Gallery or from Pictures) where is the wallpaper that is selected saved? Is there a directory where this is saved? Is there a Database where this information is saved? who handles this? Is it the wallpaper service? What if I wanted to have multiple wallpapers and have the service rotate through each of them based on some setting - every 1 hour for example - what do I need to change in order to do that?
I'm trying to find out how I can create a pop-up menu bar, after I press on a checkbox item, so I can do multiple things like delete.If anyone know about any tutorial, or article it will be fully estimated!
I'm using a custom view to display items in a listview. For some reason every time the list is populated; the first item is shown as selected (ie; orange highlight). I've tried everything I can think about to solve it; any ideas?
Please Help me for getting the selected Item from a ListView. Items for the ListView are getting from a xml file. Elements of the ListView are filled up by the adapter(adpter contains ImageView and textView). I only need the TextView content from the ListView.By using the onItemClick i get only the index of the item.
In my android application I want to get URL of the hyper link text, selected from web page in my android web browser. How can I get it? I want to URL of the hyper link (link that is clicked inside of that webview).
If I was using an ImageButton with a selector for its background, is there a state I can change which will make it change its appearance? Right now I can get it to change images when pressed, but there seems to be no "highlighted" or "selected" or similar state which lets me toggle it's appearance at will.
Here's my XML, it only changes appearance when pressed.
I have a tab bar for which I've set the initial icons and labels as necessary. I have also hooked the onTabChanged callback of the TabHost such that I'm properly getting notified when a user selects a tab.
However, I've now discovered that there's not direct way to change the indicator of a tab. Can anyone enlighten me as to how the indicator icon can be changed on a tab when selected, and I'd like to do this programmatically (i.e. not in XML preferably).
There must be some way of doing this, given the Android developer docs set forth specs on selected states for tab icons.
I have an activity with three listviews, each having three different cursors, but all have the same ContextMenu show/resolve code and when the selection event fires, I want to get the ListView to refresh it.
I can't use menuInfo.targetView, as that holds the LinearLayout for the ListView row, and not the ListView.
in this method public boolean onContextItemSelected(MenuItem item)
I have a list view full of items, after the users selects an item it lights up, and then it goes normal. Is there a way to make it so after the users select an item in my ListView it stays selected, and highlighted?
Is it possible to read the text selected by the user.. ? is the text selected by the user automatically copied to the clipboard bcoz then we can copy the text from clipboard manager? is there a way to get notified when a user has selected any text ?
