View 1 Replies View RelatedI 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:

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

On the applications screen, (the one which you drag up from the bottom of the home screen), is there any way to create folders there and re-organise the position of apps? I know that you can create folders on the home screens, but this isn't what I want to do. I would love to be able to create a folder that I can dump all of the programs I will never use but which Sony will not allow me to delete, (you know the ones - moxier etc!!)

View 2 Replies View RelatedOn an Android layout, I'd like to have a set of rows, each with two TextViews. The leftmost column of TextViews should be right-aligned, just left of an imaginary centerline down the screen. The rightmost column should be left-aligned.
Examples of this can be seen at http://stuff.greenberg.org/ScopeCalc.htm

I have set a content provider, for some reason I am able to to delete a row this way:
getContentResolver().delete(myUri, "_id=" + "3", null);
but i am not able to delete a row that way:
getContentResolver().delete(myUri, "NAME=" + "chris", null);
getting this error:
02-15 15:48:08.197: ERROR/AndroidRuntime(3043): android.database.sqlite.SQLiteException: no such column: chris: , while compiling: DELETE FROM User WHERE NAME=chris
I have checked my database file, and it is there.. but for some reason i can delete columns from my database only by the _id column, how can i fix this?

How can I make columns in Android ListView? I have this list item layout xml:

The problem is when the f.ex. wind_direction change from "4" to "300", then the columns are not aligned.
Who can this be made with fixed width of columns and using the whole width independent of devices?
I've got a question about updating an app after release. If I have a database that contains 10 columns and I add a feature that requires an 11th column after the app has been released, where would I put the sql code to add the new column so that when they install the app it keeps their current data, but adds that 11th column? Is that even possible or would I need to create another table that references the first with a foreign key?

View 3 Replies View RelatedI want my android application to create a .js file, which can then be read by my web view. I have read that the "assets" file is ready only so I cannot save a file to there during runtime. I am saving it in the default "/files/" directory.

I create a set of RadioButtons in a RadioGroup on the fly (no XML), and would like to arrange them in either two columns or two rows - right now they are in a single column. I could of course create two sets of RadioButtons, and place each in a different RadioGroup view, but presumably then I would have to control the active state of each button by taking into account both views. Does anyone have an idea how to better do this?

When I try to get the values of the columns, I get null. How can I obtain the emails? Maybe the CONTENT_URI is not correct or the data is stored in another table and I have to make a join.
I am wondering if Android's ContentResolver supports using SQL functions over the columns when you query a ContentProvider. Such as SQLite3 date functions, to get a specific date format, or datediff?

I have an XML layout which contains a TableLayout with an unknown number of TableRows...
The number of Rows will be established durin runtime, what I do know though is that I want two columns...
So I have a couple of questions regarding this :
- is there a way to set the whole TableLayout to have 2 columns ?
- is there a way programmatically to give an id to the (during runtime) created TableRows which will be placed within the TableLayout, so I can reference them later on from other parts of the software ?
I have a dynamic tablelayout that I build programmatically. Every so often one of the rows has a child SeekBar.
How I can programmatically make these SeekBars span across all the table columns?

View 5 Replies View RelatedI am trying to create a Servicefor my application which will negotiate Bluetooth connections and data. I want this service's lifecycle to start and end with the Application, but still be able to have specific Activities listen for events that occur within this service (in addition an Activty should be able to call specific methods of the Service to write data or query connection state).
I started by creating AIDL interfaces for my callbacks and service, but I can't figure out exactly what I'm doing.
How is the best way to go about this? EDIT: To be clear, I do not specifically need (or want) more than one process for my application. Right now I don't have more than one; I'm just using AIDL because it is the only way I know of for a Service to communicate with an Activity.
I read http://developer.android.com/guide/topics/resources/resources-i18n.html. But it shows how to localize your app for the currently selected locale of the phone. However, I want to add a "language" option into my own app, and allow the user to switch the UI language independent of the phone's locale setting.
My currently solution is to manage a string table myself, and dynamically edit the text string of every UI element. However, this is rather tedious. Is there a better way?
