I'm trying to have a ScrollView centered top to bottom within its parent, but I'd also like the ScrollView to be no taller than the height of it's child. The child's height is variable. If there is room, the ScrollView should stretch to be exactly the height of it's child. Any suggestion on how to set up this layout?
Put the ScrollView inside a android:layout_height="match_parent" RelativeLayout.
set the ScrollView to android:layout_centerVertical="true".
Set the ScrollView's height to android:layout_height="wrap_content".
This should get you a centered scrollview that is up to but no taller than the relativelayout that contains it.
Out of curiosity, why do you not want the scrollview set to fill_parent/fillViewport? I would suggest doing that, and simply centering the content of the scrollview instead.

I need display a Layout on botton of ScrollView such as:
1 - If the height of the content of the ScrollView is less than the height of the ScrollView, the Layout should be at the bottom of the ScrollView
2 - If the height of the content of the ScrollView is greater than the height of the ScrollView, then the Footer Layout should hide and only show Title.
When user scroll up to end of content, then Layout footer also scroll follow content.
PS: I'm using scrollview and must use it for my project.
I am confused on the following:
If I have a LinearLayout as part of a hierarchy and I want to programmatically change its position so that it is in the center of the parent layout how can I do this?
There are too many gravity attributes.
Should I update the gravity of the layout params of the item or of the parent?
If the parent is a LinearLayout you can use android:layout_gravity="center" on that view to center it in its parents view.
If the parent is a RelativeLayout you can use
android:layout_centerInParent="true"
I would generally use a RelativeLayout as a parent view if you want to center views inside it
Is there any way to have a ScrollView with android:fillViewport="true" and a child LinearLayout filling all the view when the content of the LinearLayout is not hight enough?
So far, in a LinearLayout inside a ScrollView we have to use android:layout_height="wrap_content". Can we add something else for filling all ScrollView?
What's the point? LinearLayout content won't stretch to fill ScrollView anyway. If you want to center LinearLayout in (fillViewPorted) ScrollView, use android:gravity="center" in LinearLayout. If you want to use LinearLayout weights to fill screen, don't use ScrollView, as it's height is potentially infinite. If
Set the android:layout_weight of the contents to 1.0. That will force the contents to use the available empty space when it is shorter than the ScrollView. It only works when android:fillViewport=
"true" is set on the scroll view.

<ScrollView>
<LinearLayout>
<TextView/>..
....
..
</LinearLayout>
</ScrollView>
You can add multiple items inside a LinearLayout. Since ScrollView is scrollable it won't affect the dimensions of the Views inside. You can add as many views as you need without worrying about screen size or View size..
You should add a LinearLayout as the only child inside your ScrollView. Then get a reference to that LinearLayout :
mLayout=(LinearLayout)findViewById(R.id.myLayout);
and then add Views dynamically from code using :
EditText et=new EditText(...);
//....
mLayout.addView(et);
A ScrollView can have only one direct child, so you need to put all the other Views in a Layout, such as LinearLayout and put that layout in ScrollView
Make your ScrollView's height as match_parent and the inner LinearLayout's height as wrap_content. The LinearLayout will stretch according to the number of children inside it and if the height exceeds the height of the ScrollView, the overflow can be seen by scrolling. If the ScrollView and inner Layout both have same height or if ScrollView have larger height than inner Layout, the scrolling won't happen for obvious reason.
