My question is this: i was looking at the "Hello world view: gridview" example and was wondering, how do i load all my images dynamically. for example in the ImageAdapter.java file, at the end there is:
CODE:..........
But what if i dont know the images name (as the user will add new images). what i would like to do is grab the image name from an xml file and then load it into an array.

I have an application that will have 5-15 buttons depending on what is available from a backend. How do I define the proper GridView layout files to include an array of buttons that will each have different text and other attributes? Each button will essentially add an item to a cart, so the onClick code will be the same except for the item it adds to the cart.
How can I define an array so I can add a variable number of buttons, but still reference each of them by a unique ID? I've seen examples of the arrays.xml, but they have created an array of strings that are pre-set. I need a way to create an object and not have the text defined in the layout or arrays xml file.
Update - Added info about adding to a GridView
I want to add this to a GridView, so calling the addView method results in an UnsupportedOperationException. I can do the following:

Is there a way to convert JSON Array to normal Java Array for android ListView data binding?
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 am having a similar issue while trying to use a GridView in a PopupWindow. On my Activity's onCreate method, I am inflating a gridview from xml as follows:
CODE:......................
I would like this GridView to popup on a button click. Also inside of my activity's onCreate,
I have:

On button click, I am throwing a ClassCastException from GridView.onMeasure(int, int).
I have a gridview that is inflated by multiple buttons. I used just a gridview and it worked fine. The grid was in correct order and was centered. Although, I wanted to add a button below the grid of buttons that was different and centered. To do this I decided to section off the gridview and then add the button (therefore it wouldn't be affected by the gridview).
I tried the following code to seperate the views:
CODE:...................
The problem is that this code smushes the gridview to the left and oddly it flips it (Position 0 is ont he bottom right and the last button is on the top left pushed off screen). The following image shows what is the result:
Any idea why its pushed to the left and flipped? Or maybe how I could have just the Gridview with the button on the bottom?
I'm trying to use a custom listSelector on a GridView. When I use the default listSelector, I see that it modifies the size of my items so the listSelector display correctly. The list Selector is bigger than my items:
See how when using the default selecto, it make grid items to be resized. Above the gridview I have a LinearLayout with 4 of the same images(ImageView) the GridView contains. http://twitpic.com/2hxkjh
I wanted a custom listSelector, not as bigger as the default (that makes my items smaller), but bigger enough to simulate a border on them without overlap my items content. I'm, not sure if this is an expected behavior, but when I set the listSelector with my own image, I see the selector being fit to my items size. At least my items won't get resized. [url]
Any ideas of how to set a selector that doesn't get resized?

View 3 Replies View RelatedI have a GridView that displays images, which are, unfortunately, of different sizes. They are shown in between two lines of text:
CODE:.........
If IMAGE1 is the same height as IMAGE2, everything is fine, but if IMAGE1 is longer than IMAGE2, text2.1 will run into text3.1 (padding doesn't seem to help much, as there's too much of it when images are of the same height).
I know there's a way to stretch the images in the ImageView so they are the same height, but is it possible to keep images as is and set the row height somehow?

View 2 Replies View RelatedI'm trying to disable the highlighting of objects in a GridView in Android 2.2. I did find another article saying that I should set the selector to a transparent ColorDrawable, but the views in my GridView are still dimmed when I select them. I'm just using the GridView to display static objects (right now it's text, but I plan on switching it to simple images). None of these objects will be selected. Would it be better to just use a basic view and draw my images manually with quartz?

Also I have question on performance issues on how horizontal scroll view works.
I have to show 1000 objects and for this I have to create objects and add it to view and scroll view works fine. This seems a lot of memory is there a way we can make horizontallscrollview behave like gridview so that it request for only particular objects to be created when needed.

I need to create a home screen (menu) with four to six items arranged in a grid view, each item needs to have an icon and a text below the icon.

View 2 Replies View RelatedI have a grid view of buttons that is generated by a CursorAdapter. When the CursorAdapter is passed to the Gridview the view renders correctly however the first item in the grid does not fire the OnClickListener event.
If I select another button in the grid, the event fires correctly however if I selected the first button then another button, it loads the first button action then the section button action.
When testing this, it only seems to be an issue in Android 2.2 on my emulator, my 1.5 phone works as expected. I've wiped the emulator but that doesn't seem to have made a difference.
