layout_weight inconsistency

Question

My app should look like this:

This is how it should look, though the way I had it before it wasn't scaling well. So that's why I am doing this, but it is giving me lots of problems.

But with even seemingly identical setups, the second row takes up all of the room, making it look like this:

Any explanation why it is doing this? It beats me. Here is my XML, any solutions?

Answer 1

The height on the middle LinearLayout is set to wrap_content, which is not what you want. Set all immediate children of the root LinearLayout to layout_height="0dp" and you will get all items evenly distributed in height.

Also, the weightSum=7 is unneeded if you intend for all elements to take up 100% of the container height.
