Android : Need To Create Bitmap From Integer Array In C / OpenGL

Nov 29, 2009

I am trying to move my code from Java to C, and I have encountered a problem while trying to find a function in C that can take an array of ints and create a bitmap from it for OpenGL. In Java, I used

bitmap = Bitmap.createBitmap( {int array name} , w, h, Config.RGB_565);

Is there a similar function that I can use in C, or a workaround that I could use?

Also, if it matters, I am programming for Android.

Android :: Setting Intent Extra Value That's An Array Of String And Integer

Aug 3, 2010

I have a program that sends a broadcast Intent that needs an "extra" value.The value is declared as being of type Object[], though I know that the elements are always of type Integer or String.That's part of an API not under my control. What's the most concise and/or efficient way to do the equivalent of the putExtra call below?

Android : Get An Integer Array From Axml Resource In Droid Program?

Jan 14, 2010

I have an xml resource in res/values/integers.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<integer-array name="UserBases">
<item>2</item>
<item>8</item>
<item>10</item>
<item>16</item>
</integer-array>
</resources>

and ive tried several things to access it:

int[] bases = R.array.UserBases;

this just returns and int reference to UserBases not the array itself

int[] bases = Resources.getSystem().getIntArray(R.array.UserBases);

and this throws an exception back at me telling me the int reference R.array.UserBases points to nothing

what is the best way to access this array, push it into a nice base-type int[] and then possibly push any modifications back into the xml resource.

I've checked the android documentation but I haven't found anything terribly fruitful.

Android :: Look Up Position In Spinner From String Array?

Aug 24, 2009

I 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.

Android : Way To Create Spinner Programmatically From Array

May 6, 2010

I'm all new to Android and I'm trying to create a spinner programmatically and feeding it with data from an array, but Eclipse gives me a warning that I can't handle.

Here's what I got:

This ArrayList holds the elements that should be in the spinner (gets filled from a file later on):

ArrayList<String> spinnerArray = new ArrayList<String>();

This is code ...

Now the second line (ArrayAdapter...) gives me a warning in Eclipse saying "ArrayAdapter is a raw type... References to generic type ArrayAdapter<T> should be parameterized", I have no idea how to fix this (or what that means in the first place :) ).

It's just a warning and the App seems to run alright, but I'd still like to understand what's wrong and fix it.

Add To Spinner From Array

Dec 5, 2011

I've added a spinner to one of the pages within my app. When the page(activity) loads it calls a web service and the values that are returned need to be displayed within the spinner.

I've found lots of examples where you can add values from an array but the array values are always hard coded. I need to be able to add whatever is returned from the service into an array and then add that to my spinner.

Is this possible?

Android :: Converting Byte Rgb_565 Array Into Argb Or Rgb Array

Jan 12, 2010

I have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);

where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);

The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?

Android :: Converting Short Array To Byte Array

Feb 16, 2010

I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?

Android :: Navigating An Array - String Array

Oct 12, 2010

I'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.

Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);

That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.

CODE:................

But Like I said, I would like to just order through them one by one when a button is clicked.

Android :: Spinner Widgets Look Different On Different Devices - Can Define Own Spinner That Looks Same On All Handsets

May 20, 2010

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.

Android :: Call Spinner's Value - Use Other Values Based On A Spinner's Value

Jan 25, 2010

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'

Android :: Popup List Like Spinner Without Spinner

Jan 25, 2010

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?

Android :: Menuitem Id In Xml Format Can't Be An Integer?

Mar 16, 2010

in menu.add, you add an integer menuitem id.But when you specify the menu in xml, @+id can't take an integer, so you can't test the id for the menu item as an integer in a switch statement.What obvious thing am I missing, because surely an inconsistency this bone-stupid couldn't have passed muster with all those wonderful geniuses at Google.

on top of that, when I give the menu item a name like "@+id/myMenuItem", item.getItemId() returns an integer, a long one, which I guess is a representation of the hex pointer.

But what if I have in the activity - code defined integer variable and I want this integer variable also be shown on the display?

How do I PUSH the integer variable to the XML??? From main XML reference to other strings in XML is easy - @string/app_name ... but how do I use the integer variable from the activity?
