Scroll View - Need more screen space in android studio

Question

I am trying to create a small unit converter app and need more screen space. After viewing previous questions I tried to switch my layout to a linear view and add a scroll view, but I still cannot add any additional elements to the page. Everything contained within the linear view is still set to the same size as the screen even though the window is scrolling.

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="fill_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".TestActivity"
android:id="@+id/scrollView"
android:fillViewport="false">

<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/temperatureEditText"
    android:hint="Enter Temperature"
    android:layout_below="@+id/temperatureTextView"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true" />

    android:layout_alignParentLeft="true"

</LinearLayout>

</ScrollView>

How to I increase the length of the screen? I tried to set the Linear view length to fill parent and that did not work either.

Answer 1

Changing android:orientation="horizontal" in the `LinearLayout' will allow it's contents to fill the parent properly

Answer 2

You have to change your orientation to horizontal
