Can't figure out why scrollview is not scrolling

Question

I'm making a simple converter app. Trying to convert input and display it in the EditTexts below but my ScrollView doesnt work.(Literally does nothing) I use ConstraintLayout as root and I have LinearLayout inside it which is the root of ScrollView.

So, What am I missing here?

<?xml version="1.0" encoding="utf-8"?>

            </LinearLayout>




        </ScrollView>
    </LinearLayout>


</android.support.constraint.ConstraintLayout>

i think its probably because of **android:layout_height="fill_parent"** try changing it to *wrap_content* or *match_parent* see if that helps. — SepJaPro2.4, Jul 05 '17 at 08:34

try this make your scroll view android:fillViewport="true"

<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">

 <LinearLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:orientation="vertical">
  // add here all your controls
</LinearLayout>

</ScrollView>

Yes this worked but It scrolls and shows half of the EditTexts on landscape mode. It works fine on portrait tho. – gunesevitan Jul 05 '17 at 08:45

Put an empty view with fixed height

<View
   android:layout_width="match_parent"
   android:layout_height="50dp" />

as your last item in the linear layout which is a child of scroll view..

This worked for me..
