Hi,
I would like to see how my app works on a 800x600 android netbook. how can i setup an emulator with this size?
thanks chris
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?
I'm binding a data table into a Spinner. But I cannot set the default selection for the Spinner based on a specified identifier which comes from the id column of the table.
How can I do that?
I have a update view, where I need to preselect the value stored in database for a Spinner.
I was having in mind something like this, but the Adapter has no indexOf method, so I am stuck .
void setSpinner(String value)
{
int pos=getSpinnerField().getAdapter().indexOf(value);
getSpinnerField().setSelection(pos);}
How can I decrease the font size of my spinner? I have reduced the spinner size to 35 pix because of which my text gets cut in half. How do i do that? Also I dont want anything to be selected beforehand. Default text should be "select some value".
View 1 Replies View RelatedI am having an Android view with a Spinner on it. I call a populateSpinner() method to add some default values to it.
I also have a onItemSelected() event which gets called before the view is completed to print.
I would like to run a code inside this block only when the user changes the selected items, not when I add or the form gets created.
I like to decrease/change the spinner size which include: 1) the spinner object size. 2) the font displayed , its size and color. 3) when I open spinner the list view which is displayed, its font size and color.

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 tried doing:
CODE:...........
But this crashes my application.
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'
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?
I am trying to populate a spinner depending on another spinner's selected item, my code is the following:
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 am trying (as many are doing) to populate a 2nd spinner out of the first spinner selected item like this:..............
View 3 Replies View RelatedSo I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file
View 1 Replies View RelatedI am currently developing a dictionary application with voice database. I would like to know about the current Android limitation on the file size. I am using a self-provided sqlite database ( > 50mb ) . I tested that once the built .apk size exceeds ~30mb the app will not be installed onto the simulator (INSTALL_FAILED_ INSUFFICIENT _STORAGE). Could anyone confirm me that if up until now there is no way to embed such large size files in a single apk ( Aimed to sell at Google Market without requiring user to download datafile afterwards). Also, is there a limitation of 1,048,576 bytes for a single file in the assets folder ?

View 2 Replies View RelatedCan somebody explain to me what makes up the installed application size? I have an apk that is about 8 MB, and often when I install I get the INSUFFICIENT_STORAGE error. I have around 25-30 MB free space on the phone. I'm doing debugging so I have to upload lots of new versions. If I uninstall the previous version then I can install the new version. The application manager claims that the app is taking up 22 MB. So back to the original question, how come the app is taking up 22 MB when it really only is 8 MB?

Is there any explaination of that?

View 3 Replies View RelatedMy app downloads .png files to the sd card for later use. I kept getting OutOfMemoryErrors (if anyone could explain this too, that'd be great!) and so I took a look at the sizes of the images saved to the sd card, and they seem to be roughly double what they are on the server. Why is this, and how can I make them smaller?

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!

I am trying to perform a rating system, where with the choices to select from returns a constant number so I can insert a value into a database. My intentions are to have 3 choices, 'Great', 'Mediocre' and 'Bad'. I would like Great to be a constant for '3', Mediocre to have a constant '2' and Bad to have a constant for '1'. I would like to insert only the numerical values if possible, any easy way to do this?
