Force width when generating dynamic linearlayouts

Question

I'm setting up a layout, that I'm adding to (via a for-loop) based on a set of objects. The issue is if there are say 3 fields (columns), if the middle field has a longer text length in the first entry than the second... the middle field in the first one will consume a larger width, even if I've already defined a weightSum and a layout_weight for that center column. My question is, when dynamically adding rows like this, how can I ensure that they all end up being the exact same width, as defined in the XML?

Why don't you just set a fixed width?

As in

setWidth(int width)

EDIT:

The formula to convert px to dpi is:

truePixels = DIPs * (device DPI / 160)

Here take a look how to get screen dpi.

Docs about supporting multiple screens.

Because my layout is specified using weight, so I don't get odd results on different sized device screens. If I set actual dimensions, it may cause layout issues on smaller screens, vs tablet screens – RyanInBinary Jul 05 '12 at 16:08
You can use DPI so it's compatible with different screens. – Comic Sans MS Lover Jul 05 '12 at 16:09
When you use setWidth is it looking for a dpi value? I thought it was in pixels – RyanInBinary Jul 05 '12 at 16:12
you can alwasy get the density screen and multiply the widht – Blackbelt Jul 05 '12 at 16:13
@RyanInBinary As stated by blackbelt, you can convert px to dpi. Take a look at the edit. – Comic Sans MS Lover Jul 05 '12 at 16:15

If you're using xml layout for rows then:

android:layout_width="0"

If everything is done programmatically then setWidth(0)
