Maintain fixed ration between LinearLayou and TableLayout height

In the below code, I designed so that linearLayout2 and tableLayout2 should have 1:2 height ratio. linearLayout2 contains 1 imageview and 1 table layout with 4 table rows whereas tableLayout2 contains 8 table rows.

Normally this setup works fine. But if I load a longer image in imageview1, the setup gets messed up with linearLayout2 becomes very long (same size as imageview1), but tableLayout2 srinks to minimum height.

How can I make sure to maintain same 1:2 ratio all the time?

Thanks,
