问题
I have a problem with my XML layout, something that I thought wouldn't give me many problems. I have a layout below in a scroll view, but the bottom of the layout is being cut off, I can't see anything past the second list view. From looking around, I can't seem to see anything wrong with the xml itself and I can't see what I am doing wrong.
I have tried the suggestion to the problem, that is adding a weight to each of the different elements but this still hasnt solved the problem.
I have also added the main activity in which the fragment is placed incase that might help solve the problem

回答1:
I solved the issue. As the scroll view was being displayed the bottom was being cut off by the bottom action bar on the actual phone. So to solve this I added padding to the bottom of the scrollview in order to push it back up above the action bar.
The new layout it as follows

回答2:
Add these lines in your ScrollView
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true"
android:scrollbars="vertical">
回答3:
use weightSum for all components in your xml file,
It's android:layout_weight. Weight can only be used in LinearLayout. If the orientation of linearlayout is Vertical, then use android:layout_height="0dp" and if the orientation is horizontal, then use android:layout_width = "0dp". It'll work perfectly.
From your question -- bottom of the layout is being cut off
It is because of fixed height given to components.
EDIT -- xml added

回答4:
You put a weightsum of 1 and your scrollview is 28. You have to put something like that <LinearLayout weightsum=15>(you don't have to put 15) and then what is inside your layout you have to distribute your 15 sum. Like <TextView layout_weight=1> it means that your textview is gonna 1/15. When I use weight I also put the height or the width, depending on which one I want to play, to 0dp. For exemple if I want to play on the width <TextView width=0dp height=wrap_content weight=1>. So you have to give a weight to every child of your LinearLayout.
Hope it help.
Edit: Also ListView in a ScrollView is not a good idea, could come from here. Look this post: How can I put a ListView into a ScrollView without it collapsing?
