Android :: 8 X 10 2-dimensional Array Of Buttons In Android

Mar 23, 2010

I am stuck with a problem creating buttons dynamically in android. This is what i want to do-

I want to create 8 x 10 array of buttons. Since declaring 80 buttons in main.xml isn't efficient, I want to do this in the program itself. The biggest problem is placing/aligning the buttons like a grid. I can create button objects but how do I align them in the program?

Button b = new Button(this);
b.setId(i);
b.setText("Button " + i);

Like this-

1 1 1 1 1 1 1 1 1 1
2 2 2 2 2 2 2 2 2 2
.
.
.
10 10 10 10 10 10 10 10 10 10

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 :: Assigning Custom Ringtones To Some Contacts

May 12, 2010

I tried to assign custom ringtones for few people. I did go to People -> click contact name that I want to change -> under Information tap, click Ringtone -> change ringtone. But, it doesn't work. I have two cell phones so I did try. I thought that ringtone that I made was wrong, but I go to Setting -> Personalize -> change default ringtone for same MP3 file. it works! However, I couldn't make it for specific contact. Is there any thing that I did it wrong or should I turn on or off something?

Android :: How To Assigning Photos Directly To A Folder?

Sep 27, 2010

I have to say that I don't find Android's photo management intuitive. Having got to the bottom of how to set up folders for photos, what would be very useful would be to be able to choose which folder photos get put in as they are taken, rather than having to tinker about with a file management program later on (none of which seem to use thumbnails anyway). Am I right in thinking that there is no way to choose a folder from the inbuilt camera? Is there any other camera app that would let me do this?

HTC Incredible :: Assigning Ringtones To Contact Groups

Sep 10, 2010

I finally did a factory reset after installing the froyo update and now have my phone set up just about how it was before. Problem is,I have 180+ Google contacts sorted into 11 different groups and I want to assign a specific ringtone for each group. I did this some time ago before the upgrade for each individual contact but I just don't want to do it again. Yeah I'm lazy but what can I say I thought restoring my contacts would have kept the ringtones synced but it did not.I haven't found an app that will do it (a free app anyway).

HTC Incredible :: Assigning MP3 File As Ringtones To Specific Contacts

May 14, 2010

I tried to assign custom ringtones for few people. I did go to People -> click contact name that I want to change -> under Information tap, click Ringtone -> change ringtone -> After I pick custom ringtone -> Click OK button. Simple and Easy. But, when I test with another phone that I already assign ringtone, it doesn't work!

I thought that it didn't save it, but it was still pointing my custom ringtone. Well, second thought that my custom ringtone might be working, so I go to Setting -> Personalize -> change default ringtone for same MP3 file. it works! However, I couldn't make it for specific contact. Is there any thing that I did it wrong or should I turn on or off something?

Sony Ericsson Xperia X10 : Possible To Rename - Assigning New Name To Bluetooth Headset?

Oct 13, 2010

I have several headsets and it is quite confusing as they are all called Bluetooth headset on the X10.

On my old Nokia I could rename the headset so that I could recognize it by name rather than having to switch it on and wait for the X10 to find it and connect.

Is there any way of assigning a new name to a Bluetooth headset?

Android :: String-array Max Size?

May 12, 2010

I have a string-array in my resource file that has a little over 1,000 items in it. When I go to launch the activity that calls an AutoCompleteTextView the app won't load this array it simply backs out of that activity and returns to the previous activity. If I delete a bunch of items in the array it begins to work. How can I make it hold all my items? Is there a max size associated with this?

Android :: Passing An Array To A View

Apr 8, 2010

My background is in C, but I'm relatively new to Java and to Android. I have a question as to whether I'm implementing code in the best way:

As a learning exercise in Java and in meeting the Model-View- Controller pattern, I wrote a simple game. It plays out on a 2D grid owned by the game class, and is drawn to the display by an extended View class. I have it working, but I'm wondering after the fact if I'm going about it the right way.

Here's a simplified version of what I have:
