LinearLayout not expanding inside a ScrollView
- by Felix
I have a LinearLayout inside a ScrollView that has android:layout_height="fill_parent", but it doesn't expand to the full height of the ScrollView. My layout looks something like:
level layout layout_width layout_height
1 LinearLayout fill_parent fill_parent
2 LinearLayout fill_parent wrap_content
3 (some irrelevant stuff)
2 ScrollView fill_parent fill_parent <-- this expands full height
3 LinearLayout fill_parent fill_parent <-- this does not (has orientation=vertical)
(following stuff probably are irrelevant, but just to be sure:)
4 TextView fill_parent fill_parent
4 LinearLayout fill_parent wrap_content
I can see that the LinearLayout doesn't expand the full height of the ScrollView because in Eclipse in Android Layout Editor, if I select the ScrollView (in the Outline panel) it is highlighted with a red border that fills the screen to the bottom but when I select the LinearLayout its highlight doesn't expand to the bottom of the screen. How can I get it to do so?
The effect I'm trying to achieve is to have some text and a button below it (inside the LinearLayout in level 4 there's just a button). The text can be big enough to need a scrollbar, in which case I want the user to have to scroll down in order to see the button. In case the text is not big enough for a scroll bar, I want the LinearLayout containing the button to stick to the bottom of the screen.
