LinearLayout not expanding inside a ScrollView

Question

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  lt -- this expands full height 3    LinearLayout    fill parent    fill parent  lt -- 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   At first I thought I shouldn t post the full XML because it s usually a turn-down to see a huge chunk of code in a question  However  it seems it might be necessary  so here s the full layout    lt  xml version  1 0  encoding  utf-8   gt   lt LinearLayout     android layout width  fill parent      android layout height  fill parent      android orientation  vertical      xmlns android  http   schemas android com apk res android  gt       lt LinearLayout         android layout width  fill parent          android layout height  wrap content          android orientation  horizontal          android id    id video layout          android focusable  true          style   style VideoLayout  gt           lt FrameLayout             android layout width  wrap content              android layout height  wrap content              android foreground   android drawable ic media play              android foregroundGravity  center  gt               lt ImageView                 android layout width  wrap content                  android layout height  wrap content                  android id    id video thumb                  android padding  5dip                  android background   454545   gt           lt  FrameLayout gt           lt TextView             android layout width  fill parent              android layout height  wrap content              android focusable  true              style   style VideoTitle              android id    id video title              android layout gravity  center              android layout weight  1   gt       lt  LinearLayout gt       lt ScrollView         android layout width  fill parent          android layout height  fill parent          android layout weight  1  gt           lt  -- this ScrollView expands the full height of the screen               However  the next LinearLayout does not expand the full height of the ScrollView -- gt           lt LinearLayout             android layout width  fill parent              android layout height  fill parent              android layout weight  1              android layout gravity  fill              android orientation  vertical              android id    id info layout  gt               lt TextView                 android layout width  fill parent                  android layout height  fill parent                  android id    id info body                  style   style InfoText   gt               lt LinearLayout                 android layout width  fill parent                  android layout height  wrap content                  android orientation  horizontal                  style   android style ButtonBar  gt                       lt Button                         android layout width  wrap content                          android layout height  wrap content                          android layout gravity  center                          android layout weight  1                          android text   string button readmore                          android id    id btn read more   gt               lt  LinearLayout gt           lt  LinearLayout gt       lt  ScrollView gt   lt  LinearLayout gt    At the moment I have resorted to android layout gravity  bottom  on the problematic LinearLayout  which makes the button stick to the bottom of the screen no matter what  But that also makes the text stick to the bottom of the screen  which is not exactly what I was after   Update  scratch that  android layout gravity  bottom  makes the ScrollView unable to  well  scroll  Other ideas

The solution is to use   android fillViewport  true    on Scroll view and moreover try to use   wrap content  instead of  fill parent  as  fill parent    is deprecated now

I know this post is very old  For those who don t want to use android fillViewport  true  because it sometimes doesn t bring up the edittext above keyboard   Use Relative layout instead of LinearLayout it solves the purpose

All the answers here didn t work  completely  for me  Just to recap what we wanna do for a complete answer  We have a ScrollView  supposedly filling the device s viewport  thus we set fillViewport to  quot true quot  in the layout xml  Then  inside the ScrollView  we have a LinearLayout containing everything else  and that LinearLayout should be at least as high as its parent ScrollView  so stuff that s supposed to be on the bottom  of the LinearLayout  is actually  as we want it  at the bottom of the screen  or at the bottom of the ScrollView  in case the LinearLayout s content has more hight than the screen  Example activity main xml layout   lt ScrollView     android id  quot   id layout scrollwrapper quot      android layout width  quot match parent quot      android layout height  quot wrap content quot      android fillViewport  quot true quot      android layout alignParentTop  quot true quot      android layout above  quot   id layout footer quot       gt   lt LinearLayout     android id  quot   id layout scrollwrapper inner quot      android layout width  quot match parent quot      android layout height  quot wrap content quot      android orientation  quot vertical quot       gt     content which might or might not be higher than screen height     lt  LinearLayout gt   lt  ScrollView gt   Then  in the activity s onCreate  we  quot wait quot  for the LinearLayout s layouting to be done  implying it s parent s layouting is also already done  and then set it s minimum height to the ScrollView s height  Thus it also works in case the ScrollView does not occupy the whole screen height  Whether you call  post      on the ScrollView or the inner LinearLayout should not make that much of a difference  if one doesn t work for you  try the other  public class MainActivity extends AppCompatActivity     Override    Activity protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout activity main        LinearLayout linearLayoutWrapper   findViewById R id layout scrollwrapper inner                 linearLayoutWrapper post    - gt            linearLayoutWrapper setMinimumHeight   ScrollView linearLayoutWrapper getParent    getHeight                      Sadly  it s not an xml-only solution  but it works well enough for me  hope it also helps some other tortured android dev scouring the interwebs in search for a solution to this problem  D

Can you provide your layout xml   Doing so would allow people to recreate the issue with minimal effort   You might have to set  android layout weight  1    for the item that you want expanded

I have dynamically used to get this   I have a LinearLayout and within this used ScrollView as a child  Then i take again LinearLayout and add what ever View u want to this LinearLayout and then this LinearLayout add to ScrollView and finally add this ScrollView to LinearLayout  Then u can get scroll in ur ScrollView and nothing will left to visible   LinearLayout Parent --ScrollView child of LinerLayout  -- LinearLayout child of ScrollView -- add here textView  Buttons   spinner etc whatever u want   Then add this LinearLyout to ScrollView  Bcoz only one CHILD for ScrollView applicable and last add this ScrollView to LinearLyout If defined area is exceed from Screen size then u will get a Scroll within ScrollView

Found the solution myself in the end  The problem was not with the LinearLayout  but with the ScrollView  seems weird  considering the fact that the ScrollView was expanding  while the LinearLayout wasn t    The solution was to use android fillViewport  true  on the ScrollView

In my case i haven t given the      orientation of LinearLayout ScrollView s Child    So by default it takes horizontal  but scrollview scrols vertically  so please check if  android orientation  vertical   is set to your ScrollView s Child In the case of LinearLayout       This was my case hopes it helps somebody
