Android: Views in ScrollView doesn't appear past empty LinearLayout

Question

On Android 4, I have a simple ScrollView which presents a form to fill in. Inside the view I have a number of buttons, then this Layout,

<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/layoutImages" />

then more buttons. The layout always stops rendering at the LinearLayout. If I move the layout down the list of views, all views above it appear. I can reference the other layouts in code nicely so they are there, just not visible.

Do I need to do something to the LinearLayout to prevent it from stopping the rendering of all the subsequent views?

For reference, here's the full layout:

<?xml version="1.0" encoding="utf-8"?>

Answer 1

That is because you have your layout_height set to "fill_parent" so it's taking up the rest of the space below that. That's why it works when it's at the bottom, but not in the middle. Try either changing it to "wrap_content" or using a RelativeLayout.
