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'
In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

I have got an edit text where I want that when someone insert her values it will narrow his option's. the options are stored in a DB (up to 1200 values to one editbox ). i cant get the concept of how to do it.

View 1 Replies View RelatedI 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.
Is it possible to store strings values in multiple files? Eg, strings.xml, strings1.xml, strings2.xml etc.
I do not mean localized versions of the same file - those multiple files should contain different string ids in the same language, so in code they would be refered like: R.strings1.my_string_1 R.strings1.my_string_2 R.strings2.my_string_3 etc. So, "strings1", "strings2", "strings3" would be a kind of namespace for them.
Or, another way is to have multiple R classes inside one project, which would deal with different stringsXXX.xml files.
Like, currently we can refer to "my.name.space.R" and to "android.R" at the same time, so is it possible to have: android.R my.name.space1.R my.name.space2.R etc
At the same time inside single project?
In my current app, if the string is too long and doesn't fit into screen it gets cut. How to display rolling text for long strings in a spinner(i have seen that in some apps)?
View 2 Replies View RelatedI think I have a pretty easy problem to solve, but I have been beating my head against the wall for hours trying to get past it! I have an adapter that loads a list of URLS:
adapter=new MyAdapter(this, lStrings);
list.setAdapter(adapter);
The list of URLS looks like this:
private String[] lStrings={
"http://www.domain.com/file1.jpg",
"http://www.domain.com/file2.jpg",
"http://www.domain.com/file3.jpg",
};
What I want instead is to load these values from a text file that lies on the SD card. For that matter, I would be okay with loading the values from a text file into a String, and then load the String into the list as I imagine that would be the "cleaner approach". However, all attempts to do this have failed. For instance, I replaced the above snippet with this:
private String[] lStrings=
{ MainActivity.this.getString(R.string.myurllist) };
but then I get a Forced Close on loading.
I'm a bit new to Java, Android, and development in general.
Does anybody know of a work around for the android xml file string array inability to process string <item>'s that are not legal java variable names If not, is this not a major bug? Why does an item in an array need to generate a reference id anyway? Isn't this redundant?
View 2 Replies View RelatedI have some messages being passed back from my server through php. The problem is that the messages are in English and if the user is using another language they will still get the message in English.
So I had an idea that maybe instead of passing back the message I would instead pass the String resource Id from the android app, that way the app will get the correct string id for their language. I will use this in a number of apps so I just want to know if the string id is guaranteed to be the same across different android projects?
I can access android.R.string.ok value from java code, but can't see how to do the same in layout xml file - I only have @string/xxx in autocompletion list which does not have system string values.
View 3 Replies View RelatedI 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 wanted to know whether we can implement both date and time picker in one view...
In iphone app you can pick both date and time through one view. But in android we have date picker and time picker seperately. So, is there any method by which i can get values of both date and time from one view?
Can anybody help me about how to change the contents of spinner on run time in android.

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 tried doing:
CODE:...........
But this crashes my application.
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?

why? it works perfectly for the 1st spinner.

View 3 Replies View RelatedI have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.
