Scroll View - Serve più spazio sullo schermo in Android Studio

Question

Sto provando a creare una piccola applicazione convertitore di unità e ho bisogno di più spazio sullo schermo. Dopo aver visto le domande precedenti ho provato a passare il mio layout a una vista lineare e ad aggiungere una vista a scorrimento, ma non riesco ancora ad aggiungere altri elementi alla pagina. Tutto ciò che è contenuto nella vista lineare è ancora impostato alla stessa dimensione dello schermo anche se la finestra scorre.

<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

</ScrollView> 

Come aumentare la lunghezza dello schermo? Ho provato a impostare la lunghezza della vista lineare per riempire il genitore e non ha funzionato neanche.

Answer 1

Modifica android:orientation="horizontal" nel `LinearLayout' permetterà il suo contenuto per riempire il genitore correttamente

Answer 2

Devi cambiare l'orientamento orizzontale per
