Android : Programmatically Span Columns In A Tablelayout?
Aug 28, 2010
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?

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 am displaying a table of values in my android application, and would like the columns to be distributed evenly in terms of size , instead of sizing according to content. Been playing around with stretchColumns but couldn't manage to figure out the right combination.

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.

I'm trying to use ImageSpan to add icons to a textview (small graphics, symbols like emoticons, not much taller than normal letters) and whenever I have icons on the top line of text they're getting chopped off at the top. Icons on other lines are fine.It's like the textview, when calculating its size, doesn't take into account the icon size. Any idea how to get it to calculate the size correctly, so the top of the icons can be displayed? (sorry for the repost - I tried posting this a couple of weeks ago, but got no replies)

I've a textview I want to span almost the length of the screen, then 2 buttons at the bottom.
Right now I'm using a relative layout with a textview and two buttons and I can almost get it the way I want but the only thing is the textview isn't as long as I want it. I want it to be as long as necessary for whatever handset is using it. So a constant pixel amount is out.

How can you specify a column span in an android's gridview?
I have a gridview that displays 3 images for each row. Sometimes, there are images that have to span 2 rows.
Is it possible to do that in Android?
or should I be using a different view?

I have a large text view that I am styling with a SpannableStringBuilder. I want to be able to assign custom click event handlers to certain spans of text. For example, if I click a superscript character I want it to pop up a toast with some information about what the superscript references. So far I have found linkify which helps to make regular expression type of things like emails and phone numbers launch appropriate activities. What I want to be able to do is define a span and its styling and assign a click handler to it. I haven't found anything built in that supports this kind of functionality and so I'm asking for anyone with a fresh idea of how to do this.

I my design (as an example), I would have two text fields defined in my relative layout followed by an image and I would like the image to span the remainder of the screen.
Here is what I have so far:
CODE:..........
How do I tell my ImageView to span fill the remainder of the screen. If I define the height and width as "fill_parent" it fills over the two text views.

I am having this issue where I am trying to have a single TextView span one to two lines, fill the cell completely (so you can also click edges of the cell and it will trigger) and center-align.
This is the layout for the cell:
CODE:...
However cells seems to be filled correctly ONLY if it happens to wrap around and end up spanning two lines of text. It shows center-aligned and you can click anywhere in the cell to trigger the click. The cells that do not span multiple lines of text are left-aligned and trigger (highlight) only if you click where the text is. There is a "numb" area which does not react to clicks inside the cell if the text is short.

When I was using Froyo and Gingerbread I was able to specify days and time span in which particular mailbox will sync.
I cannot find this in ICS 4.0.3 anymore. Is that intentional "progress" in Android 4.0.3 ?

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?

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?

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?
