Android - how to make a scrollable constraintlayout

Question

I want to make a layout that lets me scroll down using constraint layout  but I don t know how to go about it  Should the ScrollView be the parent of the ConstraintLayout like this    lt  xml version  1 0  encoding  utf-8   gt    lt ScrollView xmlns android  http   schemas android com apk res android      xmlns app  http   schemas android com apk res-auto      xmlns tools  http   schemas android com tools      android layout width  match parent      android layout height  match parent      android fillViewport  true  gt    lt android support constraint ConstraintLayout     android id    id Constraint      android layout width  match parent      android layout height  match parent   gt      Or the other way around  Maybe someone can point me to a good tutorial on this or give an example  I can t seem to find one    Also  I don t know if this is a bug or some configuration that I don t have set up but I ve seen images like this one      where there are some components outside the blueprint  blue rectangle  yet they are visible  while on my side if I place a component on the  white space  I can t see it or move it anywhere  and it appears on the component tree    UPDATE    I found a way to make the constraint layout scrollable in the design tool  using a horizontal guideline to push down the constraint layout border and extend it beyond the device  after that  you can use the guideline as the new bottom of the constraint layout to anchor the components

                android:layout_alignParentEnd="true"
                >

            </android.support.constraint.ConstraintLayout>

        </RelativeLayout>
    </ScrollView>
</RelativeLayout>

This is how I resolved it   If you are using Nested ScrollView i e  ScrollView within a ConstraintLayout then use the following configuration for the ScrollView instead of  WRAP CONTENT  or  MATCH PARENT     lt ScrollView     android layout width  0dp      android layout height  0dp      app layout constraintStart toStartOf  parent      app layout constraintEnd toEndOf  parent      app layout constraintBottom toTopOf    id someOtherWidget      app layout constraintTop toTopOf  parent  gt

Constraintlayout is the Default for a new app  I am  learning to Android  now and had a very hard time figuring out how to handle the default  sample  code to scroll when a keyboard is up  I have seen many apps where I have to close the keyboard to click  submit  button and sometimes it does not goes away  Using this  ScrollView   ContraintLayout   Fields  hierarchy it is working just fine now  This way we can have the benefits and ease of use from ConstraintLayout in a scrollable view

Take out bottom button from the nestedscrollview and take linearlayout as parent  Add bottom and nestedscrollview as thier children  It will work absolutely fine  In manifest for the activity use this - this will raise the button when the keyboard is opened  android windowSoftInputMode  adjustResize stateVisible    lt  xml version  1 0  encoding  utf-8   gt   lt LinearLayout xmlns android  http   schemas android com apk res android      xmlns app  http   schemas android com apk res-auto      android layout width  match parent      android layout height  match parent      android orientation  vertical  gt        lt androidx core widget NestedScrollView xmlns tools  http   schemas android com tools          android layout width  match parent          android layout height  0dp          android layout weight  1          android fillViewport  true  gt            lt androidx constraintlayout widget ConstraintLayout             android layout width  match parent              android layout height  wrap content              android orientation  vertical  gt                lt com google android material textfield TextInputLayout                 android id    id input city name                  android layout width  match parent                  android layout height  wrap content                  android layout marginStart  20dp                  android layout marginTop  32dp                  android layout marginEnd  20dp                  android hint   string city name                  app layout constraintLeft toLeftOf  parent                  app layout constraintTop toTopOf  parent  gt                    lt com google android material textfield TextInputEditText                     android id    id city name                      android layout width  match parent                      android layout height  wrap content                      android digits  abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ                      android lines  1                      android maxLength  100                      android textSize  16sp    gt                lt  com google android material textfield TextInputLayout gt            lt  androidx constraintlayout widget ConstraintLayout gt        lt  androidx core widget NestedScrollView gt        lt Button         android id    id submit          android layout width  match parent          android layout height  wrap content          android background   color colorPrimary          android onClick  onSubmit          android padding  12dp          android text   string string continue          android textColor   FFFFFF          app layout constraintBottom toBottomOf  parent    gt    lt  LinearLayout gt

To summarize  you basically wrap your android support constraint ConstraintLayout view in a ScrollView within the text of the   xml file associated with your layout   Example activity sign in xml   lt  xml version  1 0  encoding  utf-8   gt    lt ScrollView xmlns android  http   schemas android com apk res android      xmlns app  http   schemas android com apk res-auto      xmlns tools  http   schemas android com tools      android layout width  match parent      android layout height  match parent      tools context   SignInActivity  gt   lt  -- usually the name of the Java file associated with this activity -- gt        lt android support constraint ConstraintLayout          xmlns android  http   schemas android com apk res android          xmlns app  http   schemas android com apk res-auto          xmlns tools  http   schemas android com tools          android layout width  match parent          android layout height  match parent          android background   drawable gradient          tools context  app android SignInActivity  gt            lt  -- all the layout details of your page -- gt        lt  android support constraint ConstraintLayout gt   lt  ScrollView gt      Note 1   The scroll bars only appear if a wrap is needed in any way  including the keyboard popping up   Note 2  It also wouldn t be a bad idea to make sure your ConstraintLayout is big enough to the reach the bottom and sides of any given screen  especially if you have a background  as this will ensure that there isn t odd whitespace  You can do this with spaces if nothing else

TO make a scrollable layout  the layout is correct  It will not be scrollable until there is reason to scroll just like in any other layout   So add enough content and it will be scrollable  just like with any layout Linear  Relative  etc   However  you cannot scroll properly in Blueprint or design-mode when designing with ConstraintLayout and ScrollView   Meaning   You can make a scrollable ConstraintLayout  but it will not scroll properly in the editor due to a bug scenario that wasn t considered  But even though scrolling doesn t work in the editor  it works on devices   I have made several scrolling COnstraintLayouts  so I have tested it   Note  Regarding your code  The ScrollView is missing a closing tag  I don t know if it is the case in the file or if it is a copy-paste miss  but you may want to look at it

A lot of answers here  nothing really simple  It s important that the ScrollView s lauout height is set to match parent while the layout height of the ContraintLayout is wrap content  lt ScrollView     xmlns android  quot http   schemas android com apk res android quot      android layout width  quot match parent quot      android layout height  quot match parent quot       gt        lt androidx constraintlayout widget ConstraintLayout         android layout width  quot match parent quot          android layout height  quot wrap content quot  gt

There is a type of constraint which breaks the scroll function   Just make sure you are not using this constraint on any view when wanting your ConstraintLayout to be scrollable with ScrollView    app layout constraintBottom toBottomOf    parent      If you remove these your scroll should work   Explanation    Setting the height of the child to match that of a ScrollView parent is contradictory to what the component is meant to do  What we want most of the time is for some dynamic sized content to be scrollable when it is larger than a screen frame  matching the height with the parent ScrollView would force all the content to be displayed into a fixed frame  the height of the parent  hence invalidating any scrolling functionality   This also happens when regular direct child components are set to layout height  match parent     If you want the child of the ScrollView to match the height of the parent when there is not enough content  simply set android fillViewport to true for the ScrollView

For me  none of the suggestions about removing bottom constraints nor setting scroll container to true seemed to work  What worked  expand the height of individual nested views in my layout so they  spanned  beyond the parent by using the  Expand Vertically  option of the Constraint Layout Editor as shown below    For any approach  it is important that the dotted preview lines extend vertically beyond the parent s top or bottom dimensions

There is a bug in version 2 2 that makes it impossible to scroll the ConstraintLayout  I guess it still exists  You can use LinearLayout or RelativeLayout alternatively   Also  check out  Is it possible to put a constraint layout inside a ScrollView
