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:
CODE:.........
But that doesn't layout the buttons in a grid like I would like. Can this be done in a GridView?

I have an application which fetches data from server and shows it in different lists in my application. I used the adb shell procrank command to find out the memory usage of my application It takes 10 mb for the UI (I have a single Activity ,but many layout files), And the data which comes from the server is stored in memory arrays for logical representation on UI (As well as database)and it takes 6 mb of the memory .So application's runtime size reaches to 16 mb and then many a times its crashing after that with OutOfMemoryException. Another major problem is that later for the next client release , the data comming from the server will be around 12 mb.. :( :( So i need to do a major restructuring in the App.I beleive that i cannot increase my App size from 16 mb to more So my question here is , can i have two seperate applications , one of which will fetch the data from the server and keep it in memory as well as database and another App will be used for showing the UI and it will do an inter Application communication to fetch the data and display it on the UI in this App. So the 1st App wil be a backgrond App which will handle Server communication as well as data storage , the second App will start this 1st App .

Day 2, now everytime I try and connect the MTP Application screen pops up, then crashes, then pops up again, then crashes, and continues to do so until I unplug. Has anyone else experienced this and fixed it?
Changing the USB setting to anything else, such as Mass Storage, works fine.
I've tried on Windows 7 and WinXP with the same result. Drivers are already on the computer from the first time.

I have two layouts: layout-port and layout-land. If I run the app with emulator or device, either vertically or horizontally, the app runs fine with the correct layouts. However, if I rotate either the emulator or device, the app exits. There's no crashing, perse', it just exits. I have other app's with similarly defined layouts that work fine without any orientation handling in the manifest. I'm not concerned about persisting data.
The main differences between the one's that work and this one are (this one has):
* Menus with sub-menus
* Dialog screens (not the android dialog widget)
* Tab widget
All of the above items work in their respective layouts (port and land), the app just exits when rotating the emulator or device and I need to restart the app.

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?

I 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?

I'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?

I am just wondering if the children of gridview can be shown horizontally instead of vertical view.
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 don't know if it is possible, but actually I wouldn't see why not.
Can we do a grid view not just with ImageView but with a custom view.
I am trying to make a grid view of a view composed of an ImageView and a TextView.
I know that everything happens in my Adapter getView's function but I can't figure out how to do it.
CODE:................
My view has an id of R.id.fileUnitLayout. Let's say my inner TextView has an id of A and my inner ImageView has an id of B. How can I fill them ?

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. I googled and everything I could find were adapterView examples, with dynamic menu loading, and I want to make it with static xml, this view will not change so no need for dynamic code.

I 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.

I have used GridView for 2-dim grid of Buttons. My problem is, that a user may "navigate" through this grid's cells -- with use of arrow keys it is possible to move yellow rectangle and by pressing enter select cell (rectangle becomes orange for a moment). Everything is behind buttons which are placed in cells of grid. How to disable possibility to select and navigate cells of grid? I would like to still use grid view but have the same possibility to navigate (change focus) among buttons (not cells in which buttons are placed) at it is possible when I place buttons in cells of TableView (not GridView).
