Android :: Set Number Of Columns Programmatically In TableLayout?

Apr 28, 2010

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 ?

Android : Way To Enable Number Of Columns And Rows On Home Screen

Oct 9, 2010

I have been using LaucherPro for about a month now and really like it. I finally found out how to swipe gesture my dock and all.

Now my problem is that I decided to play with setting a little more and wanted to enable the number of columns and rows on the home screen. I sit my columns to 3 and rows to 1, then attempted to add widgets. However, when I do do I get a message saying that there is no more room on my home screen. I don't have anything on my home screen so I'm not understanding what I am doing wrong. I uninstalled and reinstalled LP and still the same problem.

Android :: Column TableLayout As Only Child Of Scroll View - TableLayout Width

Oct 30, 2010

I have a two column TableLayout as the only child of a scroll view. The first column contains TextViews ('labels') and the second column contains EditText/Spinner/DateWidget etc ('values').

Even though I have have specified android:layout_width="fill_parent" for TableLayout, TableRow & all widgets (in 'values' column).

The screen looks perfect when the activity is created. However, when one types a really long value in the EditText, the 'values' column goes beyond the visible screen area.

Android :: Getting Google Order Number Programmatically After App Bought From Market

Nov 20, 2009

As you may know, when you buy an app from the market, an email is sent to you with a "Google order number" (which I believe is 15 digits long), which is specific to this transaction. I was wondering if this number is stored anywhere on your device after you purchase an app, and if it is, is there anything in the API to allow an android app to retrieve this number. If this number cannot be retrieved, is there a similar market transaction code that's retrievable?

Android :: Best Layout For A Set Of Columns

Dec 31, 2009

On 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

What's the best layout to use?

Android :: Update - Database That Contains 10 Columns

Feb 25, 2010

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?

Android :: Radio Group Over Two Columns / Rows?

May 15, 2010

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?

I'm trying to create an experience very similar to Aldiko or the Kindle app in which the user can tap left or right to go to the previous or next page of text. Hope this makes sense, thanks for reading.

Android :: Sorting Results When Autocomplete Matches Multiple Columns In SQL

Oct 27, 2009

I've run into an issue with an autocomplete field I'm working on.The field I'm working with is composed of the form "<NAME> (<CODE>)".When a user starts typing in text, I want to display any results that match either NAME or CODE.For example, if this list contains items and their codes, like "Personal Computer (PC)", then I'd want the list to pop up that row if the user types "P", "PC", "Per", etc.However, the problem I'm running into now is how to best sort the results that come back from this.For example, If someone enters "PC", I want "Personal Computer (PC)" to be the first result. However, if there's another row (you'll have to bear with me as this is contrived) "PC Case (301)", then there's no simple ordering I can do on the results to ensure that the best match appears first. Ordering by name and code both returns PC Case first.I want a query where it returns the best match first, rather than items in alphabetical order.Is there such a function I can use in SQLite to get this, or should I return the results and then mess with the order in the code?
