As soon as I changed the array to a string-array, this works fine. Is this normal? I realize that I can (and will) just convert the string array values to an int, but it seems weird that I have to.
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.

I am trying to make an android widget like the Google Voice Widget where users can go through an array of Strings which is retreived from the SQLite database.

View 2 Replies View RelatedI 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?
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?
View 3 Replies View RelatedI'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.

View 5 Replies View Relatedin 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.
I started two days ago with android, gone through the hello android stuff and also started to read the Hello Android book, which is great.
PROBLEM:
I use in my app - VERY EASY APP- the XML output. So basically the main activity just tells the android to show the XML layout of main.
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?
I got an exception "Unable to parse 53.6 as an integer".

countDisplay = new TextView(this);
this.setContentView(countDisplay);
countDisplay.setText("counter here");
} }
