My code works like this to list all items in my String array - itemsarray

However, I know by this call that I only want to list the first X number of items from itemsarray. How can I load only the first X items form itemsarray into the ListAdapter?
With spinner, I am able to create a dropdownlist menu. (As seen from the code below)
Quote:
// Set up the action bar.
final ActionBar actionBar = getActionBar();
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_M ODE_LIST);
[Code]...
However, how should i make it draw a XML upon selection of the item in the dropdownlist's array? Or should i just change everything to popup menu and onclicklistner instead of spinner.
I just got a Droid, and after having used it for a while, I felt like I wanted to make a program for it. The program that I am trying to make calculates the actual storage capacity of secondary storage mediums. The user select from a list of units that ranges from KB to YB and the size the entered gets put into a formula depending on the chosen unit.However, there is a bit of a problem with the program.From my testing,I have narrowed it down to the fact that the user's selection is not really being obtained from the spinner.Everything I look up seems to point me to a method quite similar to how it works in J2SE, but it does nothing. How am I actually supposed to get that data?
View 1 Replies View RelatedI've built a dialog that asks the user to pick a city from the list provided when the application first opens. The dialog works perfectly, however I want to store the user's choice so that when the app is opened a second time, it checks to see if the user has already made a selection previously. If they have, it doesn't display the dialog and defines the city variable as their previously chosen preference. And obviously, if they haven't made a selection previously (because its their first time opening the app or for some reason the app couldn't read the stored preference), it displays the dialog.
View 1 Replies View RelatedI've implemented a spinner with an OnItemSelectedListener event handler. When I initialize the spinner and when a user makes a selection the even handler gets called. What I need is to determine when a user makes a selection. Is there a way to determine in the OnItemSelectedListener whether the event was triggered because of data initialization, or because of a user selection? Am I going down the wrong path trying to do this with the OnItemSelectedListener? Is there a better way to to capture a user selection event on a spinner control?
View 5 Replies View Relatedi have code that runs onitemselectedlistener event of spinner.So when i am in the method :
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
//I want to do something here if its a user who changed the the selected item
}
... can i know whether item selection was changed programmatically or by a user action through UI.

I'm trying to use Spinner as a button with selection pop-up. Basically I want an icon and when user clicks it - the popup list is displayed and user can make a selection. The Spinner happily accepts icon image as drawable background. Unfortunately when I select a value the text overlays the background. Is it possible to set selection text color as a transparent? Or maybe there's a better way?

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.
CODE:................
But Like I said, I would like to just order through them one by one when a button is clicked.
Is there a simple way to convert a JsonArray to a standard Java Array? Obviously, you can iterate and do it explicitly, but I wanted to see if there was a direct way to do so.

View 3 Replies View Relatedi have the following problem. I fill a ListView with a custom ArrayAdapter with data from a BD. However, in background, i'm updating those datas from the info provided by an API, so the idea is when the update finish, the adapter shows the updated data instead its "old version".
The problem is that when i do that, i notice a lag while the adapter is updating itself. Is the any efficient solution to avoid this?
Lets say I have 1 - 1,000 in a list and I click on 250. When I push the back button I want to go back to 250 not all the way back up to 1. Is this possible?

View 1 Replies View RelatedI've built an application that loads XML from a server, then creates a list of items and with that I create and adapter that I set with setListAdapter(my adapter);
The problem I'm having now is that creating the list and adapter takes time, so I was thinking on creating just like 20 entries and populate the list, then create the rest on runs background or maybe when the person gets to the bottom (like gmail application).
I am trying to use ListView and ListAdapter. If I create a simple Android project and add a ListView as the content view, and set it's adapter to my adapter based on ListAdapter, everything seems to work. My ListAdapter's 'getCount' is called, and I return 3, my 'getViewTypeCount' is called and I return 1, my 'getItemType' is called and I return 0, and for each item, my 'getView' is called and I return a TextView. Everything works, and the list is displayed with 3 items.
Now if I try and do the same thing in a more complicated environment, it does not work. My 'getCount', 'getViewTypeCount' and 'getItemType' methods are called, but the 'getView' method is never called and the ListView appears empty.
Now I know that I must be doing something wrong in the more complicated case, but I cannot see what it is. The code is really too involved to post here, but I was hoping that someone could give me some ideas as to why my 'getView' is never called even though I return 3 from my 'getCount' method.

I'm experimenting with the Android platform, and I'm beginning to love it, but right now I'm stuck, at this cursor/list adapter problem-thing.
