Notepad Sample - adding more columns to listview

 I've done the notepad tutorial on Google's Android site, but I would
like to know how to add more fields to the list, in columns. At the
moment I can add the columns no problem, but they're not aligned like
you would a normal table on the layout:

john smith
heinrich cilliers
will peck

I would like it aligned as in a html table.

Any pointers?

 Every ListView item layout is separate from those next to it - 
therefore, it positions and sizes its children without any regard for 
other list items.


Two things you can try are:

- Do not try to make a table, and use multi-line layouts instead, the 
screen is typically not wide enough to fit a proper table anyway.


- For a table-like layout, position the views within your item layout so 
that they always have the same size, regardless of the data they 
contain. This can be done by using a LinearLayout, with the children 
having zero layout_width and non-zero layout_weight values.

 Thank you so much.

I am considering breaking the table up into multiple views as one see
in some other apps.

It just seems strange that there is no way to do this in android,
however I've seen it in other apps, "Iriduim Flares" for example,
which shows many numerals in columns and it's easy to read accross,
perfect for what I needed.

Thanks again for responding.

 The popup in Iridium Flares looks like a TableLayout:

 http://developer.android.com/reference/android/widget/TableLayout.html 

TableLayout doesn't recycle views like ListView, and so isn't really 
suited for long scrollable lists, but it's just fine for presenting 
compact data (also useful for lining up controls within a layout).

 I thought one could not do a row click on a table, so I assumed
otherwise. Pity. Thanks again.
