Android Metro-Style Design Pattern

Android Metro-Style Design Pattern

I'm designing a Metro-Style Android application.
Tiles, Groups & Scrolls are done!
For who're not familiar with Metro-Style (aka Modern UI), please take a
look at the following picture.

Question :
What's the best (performance wise) design pattern for sorting tiles
dynamically in 2 rows & multiple columns ?
- LinearLayout
- - Every 2 tiles have same weight
Or
- TableLayout
- - Every 2 tiles have same row
Or
- Something else ?
