    ------     view 1 (25%)     ------       ------     view 2 (25%)     ------       ------     view 3 (25%)     ------       ------     view 4 (25%)     ------

after adding new layout programmatically

     ------     view 1 (25%)     ------       ------     view 2 (25%)     ------       ------     view  3 (25%)     ------       ------     view 4 (25%)     ------        ------     view 5 (25%)     ------

total layout 125% , scrollable. thanks

when use weights, sizes of views determined dynamically ensure views fit within size of parent - proportions determined weights.

from described, linearlayout not sound correct solution problem. listview may better approach, automatically provide scrolling functionality when total size of items exceeds size of listview itself. listview easy implement , gives scrolling , separators between items automatically. have @ listview developer's guide more information.
