Android :: Getting Values From Array

Apr 16, 2010

I have a collection of strings and declared the strings individually as arrays using ArrayList<String> al=new ArrayList<String>(); and called the arrays in the program by using al=getIntent().getStringArrayListExtra("titles");

Now, instead of declaring each of the arrays i have created SongsArray.java like below...

public class SongsArray {
private String title;
private String movieName;
private String singerName;
private String imagePath;
private String mediaPath;

public String gettitle()
{
return title;
}
public void settitle(String title) {.................

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 :: 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:

I have

Android : Use Of A String Not An Array On Another Method

May 11, 2010

Im trying to make an activity that has a multiple choice dialog after you push a button. In there you select from a list of things. But these things are received from a web method before the dialog appears. So I create a string array after I receive them inside the onCreate to initialise it there with the correct size. But my dialog method then cant get the array because propably its out of its scope.

My code looks like this:

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

I cant initialise my array when the class starts because I dont know its size yet. This has to do something with the scopes of my variables and I am pretty confused
